3. Dometic Penguin II Polar White 640315CXX1C0


  • Vigorous air conditioning 
  • 3-speed blower

  • Weight: 99 lbs


The best RV air conditioner is not only robust but also environmentally friendly. On these criteria, the Dometic Penguin II Polar White 640315CXX1C0 version is resounding. 

The usage of R410 refrigerant allows the Penguin II release heat better and eco-safe. At the same time, the AC can cover as full as a 400 square foot RV interior, only generating 13,500 btu at 3,000 wattage consumption. 

Consequently, this Dometic variant has a three-speed fan that yields a less noisy performance while giving an ideal balance of airflow. Besides, it has a versatile 10-position selector switch that is convenient when you want to regulate the temperature and the dehumidification level.

The 640315CXX1C0 can still put up it’s A-game even at colder seasons due to its heat pump included in the thermostat controller. Also, it works nicely on any RVs, whether ducted or not. 

Meanwhile, you can mount this high performing air cooler a bit easy due to its low profile. Therefore, amidst its heavyweight at almost a hundred pounds, it reduces the drag on the RV’s fuel. 

Plus, a sturdy base reinforces its stand, even passing through inclined or severe roads.

On the contrary, the 55-decibel noise while the AC runs is annoying, although its shroud’s improved design helps to have a more quiet operation.   

When you’re in a quest for an eco-friendly and energy-efficient RV air conditioning device, the 640315CXX1C0 is the best pick. You just have to shell out more bucks than the other brands when you purchase this one.

  • Weight: 105 lbs

What To Like?

The best RV air conditioner is what you truly need when you’re a full-time RVer that goes around most of the time annually. In this case, the most qualified to take the job is the Dometic Penguin HP 651816.CXX1C0.

It can cool down an entire campervan during summer, and at the same time, can warm you up in winter seasons because of its added heat pump. Admittedly, the unit can perform durably based on its specs. 

More than that, this unit works quietly and safely on either ducted or non-ducted motorhomes. Because of this, you enjoy a sound sleep inside a refreshing ambiance without any boisterous noise coming from your air conditioning unit. 

Furthermore, you can ensure a well-reduced wind resistance even if you mount this unit on the roof. The well-engineered shroud with sturdy base and brackets and compressed EPA foam disables dragging while pleasuring comfy ventilation.

However, the high amplitude of energy it consumes and its heavyweight might be its apparent downside. Of course, you don’t expect to buy this high performing RV AC at a low price. 

Nonetheless, 651816.CXX1C0 unique features compensate for its price tag. Plus, it won’t give you so much problem installing it in your rig. 

If you have the money, why not buy this one. All you what you look for an RV air conditioning equipment is here, and you can’t lose confidence in a product with these proven credentials.

5. Dometic Sanitation 143002P041 


  • simple and easy to install
  • Powerful cooling power
  • cheap


  • Noisy operation
  • Feeble shroud
  • Model: Brisk Air II
  • Type: Ceiling type
  • Strength: 13,500 btu, 110 V
  • Dimensions: 28 x 24 x 12 in
  • Weight:  75 lbs

What To Like?

You might be wondering why a non-special unit is included in this list of the best RV air conditioning equipment? Well, the Dometic Sanitation White 143002P041 Rivet-SemiI has its uniqueness to brag about that lures many trailer owners.

Owners with smaller recreational vehicles might be rushing to purchase this when sellers put it up for sale. The featherweight materials and its simple non-ducted roof installation catch that much appeal.

Despite that meager size, Brisk Air II is mighty at 13,000 btu generated at 110 voltage. This magnitude can still manage to fill up an RV inside ranging from 200 – 300 square feet wide. 

This performance is remarkable for a device that you can buy affordably. Sad to say, the low price always has downhills such as loud grumblings and feeble shrouds.  

Therefore, you have to anticipate the Brisk Air issues related to endurance and longevity, even if it’s not massive and bulky. Nevertheless, the company guarantees a 2-year warranty for this device. 

The Brisk Air II suits a van with the most straightforward interior. You don’t have to raise vast sums of money just to get this one.

6. Airxcel Mach 15 08-0080 


  • Strong cooling power 
  • Superb heat 
  • ⅓ hp blower with 320 CFM
  • Durable materials
  • affordable


  • Noisy operation
  • Model: 08-0080
  • Type: rooftop/non-ducted
  • Strength: 15,000 btu 1,800W 120V
  • Dimensions: 42 x 28 x 16 in
  • Weight: 90 lbs

What To Like?

Surely, you’ll love the Airxcel Mach 15 08-0080 as the best RV air conditioner for its supreme cooling strength among rooftop air conditioning equipment. It has a registered magnitude of 15,000 btu at an efficient 1,800 watts, produced by 120 volts. 

Even more, Airxcel Mach 15 08-0080 has a ⅓ hp motor that can produce a whopping 320 CFM airflow. This baby can fill in a motorhome with at least 350 square feet inside space or more extensive. 

Furthermore, the mightiest rooftop-mounted air conditioner is also a superb heater that can generate 5600 electrical heat energy. Thus, you can have an RV air conditioning device and a warmer at the same time. 

Interestingly, the manufacturer has integrated an all-copper tube and gas-flux fused joints, and incorporated a condenser coil and lace fins. These features ensure the high performance and efficient heat dissipation at a consistent and enduring basis. 

Also, Airxcel Mach 08-0080 has a meticulously engineered design that prevents blow down straight and swings nicely without restraining the motor. Besides, this version is resistant to corrosion because of the plastic shaft and stainless steel shroud.  

Meanwhile, with all these tremendous feats, installing 08-0080 in your van might take longer. Not to mention its 50-decibel noise when you turn it on and stays longer. 

It’s seldom that you can find a product with these abilities at a low and affordable price. Admittedly, while on the road, the chilling effect has soothed you to sleep before you suffer the noise it makes throughout the trip.

7. Airxcel Mach 3 (08-0079)


  • Strong cooling power 
  • Superb heater 
  • ⅓ hp blower with 320 CFM
  • Energy efficient
  • Eco-friendly R410 agent
  • Durable materials
  • affordable


  • Noisy operation
  • Bulky
  • Model: 08-0080
  • Type: rooftop/non-ducted
  • Strength: 15,000 btu 1,800W 120V
  • Dimensions: 42 x 28 x 16 in
  • Weight: 90 lbs

What To Like?

What could be more astonishing than robust cooling capacity, impressive warming function, low energy use, and eco-friendly energy emission? With these aces hiding in the sleeves, the Airxcel Mach 3 08-0079 should be in the best RV air conditioner list.

The Airxcel 08-0079 version has similarities with Airxcel 08-0080, except that the former has a registered strength of only 13,500 btu. Regardless of its thermal rate, 08-0079 can cover as large as 400 square feet rig using only 1,075 wattage generated by an unyielding electric current of 120 V and 15 A. 

Similarly, Airxcel 08-0079 also has a ⅓ hp fan motor that dissipates 320 CFM airflow, which is akin to 08-0080. Moreover, the integrated R410 when charging enables the AC energy efficiently, reinforcing the chilling effect, and safely emitting hot air. 

In winter seasons, you can still rely on Airxcel 08-0079 equipped with an optional warmer that can make 5600 units of energy. Indeed, a perfect AC device for full-time trailer van riders. 

You can easily regulate the rig’s atmosphere by configuring the thermostat using a three-position selector switch. This option gives you flexible choices of warming up, cooling down, or balancing the hostile atmosphere. 

Meanwhile, when it comes to durability, Airxcel 08-0079 remains in the conversation like its relevant appliances. The air conditioners’ set-up has full-copper tubes, formidable brazed gas-flux, evaporative condenser coil, stainless steel shroud, and plastic shaft.

Mainly, with these materials, it can shrug off any oxidation or corrosion. Thus, proper maintenance can make this RV air conditioner last for about five to ten years.

Regarding installation, we recommend that you mount this baby directly to the bulkhead to avoid angle issues. Lastly, this device can withstand any weather or road condition. 

However, expect a busy bee like this AC to exert too much noise like its relative Airxcel 08-0080. Though it’s easy to install, the bulky appearance is as if a sore in the eyes.  

Mach 3 is a perfect match when what you want is the cooler function of a Dometic 651816.CXX1C0, and the energy saver of a Dometic 640315CXX1C0, but you can’t afford the brand. The Airxcel manufactured air conditioners can provide the same magnitude at a low price, but it can’t work as quietly as a Dometic.

8. Airxcel 08-0212 Mach 8  


  • Light to medium cooling
  • Elect-A-Heat
  • Eco-friendly R410 agent
  • 300 CFM
  • Durable materials
  • Easy installation


  • Low thermal unit
  • Model: 08-0212
  • Type: Rooftop 
  • Strength: 9200 btu 1500W 110V
  • Dimensions: 9.99 x 9.99 x 9.99 in
  • Weight: 112 lbs

What To Like?

Amazingly, the best RV air conditioner list also includes air conditioners that can do awesome jobs for petite trailer vehicles. For this factor, we added the rooftop-mounted Airxcel 08-0212 Mach 8.

The Airxcel 08-0212 jives well on small motorhomes that provide enough height clearance. With a fiberglass fitting, the AC unit has a high-endurance quality that is guaranteed for longevity.

Meanwhile, the apparent weakness of a small unit is a low cooling capacity of just 9,200 thermal sizes. But, you can still be aware of its chilling sensation when passing by places with temperate climates. 

Moreover, the low thermal rate’s right side is the energy-saving mechanism due to the presence of R410 at 300 CFM. This feature reinforces the cooler despite the limited strength through eco-friendly hot air dissipation.

Aside from that, the manufacturer has loaded this petite 08-0212 with Elect-A-Heat equipment that makes it warmer at times. More importantly, it has a super silent fan that significantly reduces the noise when the unit is running. 

If you’re a newbie in the trailer van rental business, Airxcel 08-0212 is a good start-up investment. You just have to pick your routes and avoid super hot locations to prevent choosy clients’ adverse reactions.

9. Coleman-Mach 02-2212 Mach 3 Plus 48203C969


  • Remarkable cooling strength
  • 320 CFM Airflow system
  • Energy efficient
  • With optional heater
  • Durable
  • Easy installation
  • Works quietly


  • Requires retrofitting to most RVs
  • Model: 48203C969
  • Type: Rooftop 
  • Strength: 13,500 btu 1400W 115V
  • Dimensions: 42 x 98 x 16 in
  • Weight: 95 lbs

What To Like?

It’s not arguable that Coleman-Mach 02-2212 joins the ranks of the best RV air conditioner. With its sensational profile as an air cooler, recreational vehicle owners will surely vouch for this appliance.

Primarily, Coleman 02-2212 is peculiar for its huge evaporator/condenser coils, and lance fins that make it dispel hot air swiftly. Not to mention the full-copper tubing and resilient gas-flux brazed, which makes the unit last longer through time into various severe environments. 

Of course, with a thermal rate of 13,500 btu, Coleman 02-2212 can go toe-to-toe with the other air conditioners. Similarly, this appliance uses only 1400 watts at 115 volts, which is remarkably astounding. 

Such efficient energy can fill up a trailer van as full as 300 square feet inside dimension. Besides, it has a blower with multiple speeds that produces an airflow of 320 CFM that freezes further the already cold atmosphere.

Concurrently, Coleman 02-2212 is significantly reliable, even on winter days. This appliance also possesses a robust optional warmer assembly that generates 5600 measures of pure electrical hot air energy.

Unlike the other series, this one works quietly due to its quick airflow system. Therefore, you have a guaranteed indulgence of a sound sleep amidst long travels.  

Surprisingly, his baby requires retrofitting to ensure proper installation. Though it is still easy to mount, it does not always fit at the first try.

Thus, if you’re not used to with this thing, call a professional to install it to ensure stable fitting.    

To keep up with the RV rental industry, the Coleman 02-2212 can level the playing field. It is the trailer that campers are looking for, yet it won’t hurt your capitalization.

10. Honeywell MN10CESWW Portable RV AC


  • vigorous cooling strength at 10,000 thermal unit
  • Energy efficient
  • 3-in-1 function
  • Self-evaporating system
  • Dual drainage
  • featherweight
  • Washable filter


  • Requires window vent for installation
  • Model: MN10CESWW
  • Type: portable
  • Strength: 10,000 btu 
  • Dimensions: 15.2 x 18.1 x 29.4 in
  • Weight: 71 lbs

What To Like?

You might find it phenomenal if we raise the bar for the best RV air conditioner. At this level, the Honeywell MN10CESWW is in a more super league of top performances for an AC unit.

A portable AC with a thermal unit of only 10,000 btu can cover as much as 350 – 450 square ft full RVs. This feat is more exemplary than those of the Dometic, Airxcel, and Coleman rooftop versions with a thermal unit register of 13,500 to 15,000 but.  

Aside from that, you may force up this equipment with 2 AA batteries included in the box. Thus, it has safe protection from thermal overload, assuring you that this AC won’t fail you quickly.

Furthermore, this baby has 3-in-1 functions such as a cooler, fan, and dehumidifier. Thus, it includes a straightforward digital remote control, making it simple to regulate the duties and thermostat.

Interestingly, you don’t have to worry so much if the weather is too humid. The MN10CESWW has a self-evaporating mechanism that serves as a dual drainage system. 

Moreover, you are also assured of clean air because this ready-to-go air conditioner has an efficient filtration system that prevents any dust or dirt. Plus, this filter is washable so you can maintain the appliance regularly. 

It is impressive to house its condenser, compressor, and evaporator underneath its shroud as a featherweight appliance. And because it is portable, you can bring this anywhere.

However, it does not have a permanent window vent for installation. 

The MN10CESWW might be the best pick if you hate the installation complexities of both rooftop and window type. Besides, this baby can cool down far better and efficiently than other brands.

11. Honeywell MN12CESWW Portable RV Air conditioner


  • Stronger cooling strength than MN10CES
  • Energy efficient
  • 3-in-1 function
  • Self-evaporating system
  • Dual drainage
  • featherweight
  • Washable filter


  • Requires window vent for installation
  • Model: MN12CESWW
  • Type: portable
  • Strength: 12,000 btu 
  • Dimensions: 15.2 x 18.1 x 29.3 in
  • Weight: 68.3 lbs

What To Like?

The Honeywell MN12CESWW is similar to its previous version except that it is colder, more reliable, and less burdensome. Therefore, this more advanced AC deserves a spot among the ranks of the best RV air conditioning device. 

This product shares almost the same features with the lesser version. For example, this can do 3-in-1 functions (cooler, fan, and dehumidifying), has washable filters, 24-hour saving timer, 3-fan speed, and remote control.

Aside from that, this also has a self-evaporating/dual drainage system, and a very compressed physique to cover the compressor, condenser, and evaporator. This incredible because this version is a few pounds less dense than the previous one.

However, it is 2,000 thermal rate mightier than MN10CES, that can room up to 400 – 550 square feet. 2 AAA batteries are responsible for producing such magnitude. 

Also, it shares the same disadvantage of a non-permanent installation vent like the lesser device.   

If you’re looking for a manufactured handy air device, you can pick this instead of the MN10CES. The MN12CES is more robust, yet the features of the 2 are equally phenomenal.

12. Advent ACM150 RV Air Conditioner 


  • Immensely durable body
  • Robust chilling performance
  • With heater plug strip
  • Cute size and weight


  • Eats a lot of energy
  • Model: Acm150sp & acdb
  • Type: rooftop
  • Strength: 15,000 btu 2800W 115V
  • Dimensions: 33.46 x 25.6 x 15 in
  • Weight: 68.4 lbs

What To Like?

What’s the use of a freezer-like RV AC if you can’t bring it to any adventurous ride? This concern is not an issue with Advent ACM150, which also deserved to be a contender for the best RV air conditioner title. 

Despite its meager size and weight, the rooftop-mounted unit has reinforcements such as high-grade materials, an inexorable metal base pan, thick vent opening, and six dense foam support pads. These structures make the ACM150 an immovable force amidst the harshest road conditions your RV might hit. 

Not only that, but ACM150 also has a mighty chilling prowess coming from the combination of a 3-speed fan and 15,000 btu. This air conditioning strength can room as full as 400 – 500 square feet of RV’s inside space. 

Plus, this baby can also serve as a warmer by just turning on the plug-in heat strip. Thus, a versatile RV AC unit makes campers enjoy roaming everywhere, whether in summer or winter.    

Meanwhile, though this baby does not eat so many slots, yet it consumes so much energy. It consumes quite a massive 2800 watts generated at 115 volts. Therefore, make sure that your RV’s fuel is fully tanked and with an extra generator. 

For regular campers of extreme environments, the ACM150 can go side by side with your adventures. It can warm up and chill down; all these at an affordable bundle.

Massive energy usage of an average 2800 – 3000 watts is the significant downside of a workhorse AC with a thermal rate of 13,500 btu. But not Atwood 15027 with the exceptional, efficient usage of 1400 W at 110 V. 

Imagine filling up a 300 – 400 square foot-wide rig for a long trip without eating so much fuel. Plus, the airflow of 360 CFM and the downward direction of air augments further the AC’s thermal rate, which can freeze up the already cold surrounding.

Besides, regulating the thermostat level is not a problem due to a dual control system, a digital device screwed to the wall, and remote control. This improvisation means that the blower and condenser work separately, which reduces the noise when running.  

For a ducted AC, the Atwood 15027 has a significantly engineered design featuring a renewed frontage, which also increases wind resistance. Therefore, it minimizes the drag and saves more fuel. 

However, this baby is relatively more prominent than the other contenders, which might give you a hard time mounting it on the roof. Someone must lend you a hand to properly install the RV AC unit.

If you wish to sustain a refreshing ambiance while traveling miles away, without burning so much fuel, Atwood 15027 is the right pick. Efficient energy usage can extend more adventurous camping at a lesser cost.

Buyer’s Guide for RV Air Conditioners

Whether you’re tech-savvy or not, you must have adequate knowledge about some fundamental elements in your quest for the Best RV air conditioners. You need to check in a particular unit using these criteria because it would quickly hint whether it fits your motorhome.

Cooling Power

For starters, the potency to chill down the room temperature of your van consistently is the primary feature to look for in selecting the best RV AC. Some appliances gradually decrease the temperature but chill longer, and there some that reduce the temperature quickly but on short bursts only.

The British Thermal Unit (BTU) indicates the strength of AC, which must be proportionate to the motorhome dimensions. It means that the larger the RV is, the higher the thermal ratings it needs.

However, relying on the thermal unit alone is simplistic thinking. There are air conditioning devices with 15,000 btu, yet it hardly covers a 350-square-foot rig, and there are devices with only 10-12 thousand thermal rates but can freeze a 500-sq ft RV.

Other variables contribute to coolness, such as blower, fan motor, airflow system, and dehumidification functions.   

Power Consumption

It is also essential to search for appliances that employ lower power consumption regardless of its capacity to chill down. Reduced wattage requirement to consume makes an RV air conditioner cost-effective, especially for extended usage. 

Devices with the AC strength of 5000 to 7000 thermal rate can already burn up to more than 1700 watts at start-up and greater than 600 watts while running. You also need to point in the weather when you expect a higher using rate during hotter seasons than colder and wet periods. 

Not to mention the electrical heat power to consume when the air conditioning unit has an optional heater and operates on winter seasons. 

Power Compatibility

Besides as a cooler and cost-efficient, you also need to consider the compatibility of your air conditioning unit’s power requirement with the power source available in your recreational van. Failure to manage this might result in either device malfunction or unlikely discharge of your motorhome.

For instance, some air conditioning devices need a more stable energy connection while some do not. However, the problem comes in when the trailer van cannot handle the demanded power to operate an RV air conditioner swiftly.

Therefore, you must load your vehicle with a generator to ensure that you have a sufficient supply of energy intended for long travels. 

Air Purification

To have an air purifier included when you buy an RV air conditioner adds value to the offered deal despite its non-essential components in the performance of the air cooler. However, surely you don’t want your vehicle to sustain any unpleasant odor.

Noise Level

Most air conditioners are noisy primarily when you use them for a very long time. Because of this, camping trips could be annoying when the air cooler is noisy. 

Fortunately, more modernized brands have quieter units that run for only about not less than 35 to not louder than 80 decibels. This measure is milder when you compare it to the sound of conversation about more than 40 but less than 60 decibels.  

We strongly recommend that you pick the best RV air conditioner with the latest and most advanced designs. If you can’t afford it yet, maintain your air conditioner substantially when it ages so meticulously. 


In the real sense, it’s not a joke when you neglect to note the clearance height, size, and weight of your desired RV air conditioning equipment in proportion to your rig’s inside. What use do you get from a powerful air cooler if it does not fit in your motorhome?

Primarily you need to determine the dimensions of your desired AC unit concerning the aspects of your trailer van. This criterion may affect the ease or difficulty of installing an RV AC. 

It is your basis in deciding whether to have window type, rooftop, or portable appliance. Not all classes have the same capacities to cover large or small interiors. 

That’s why you need to know how much space is still available to fit inside the van and whether it can provide fresh air sufficiently. 

Finally, the weight of the air conditioner significantly affects the driving speed of your motorhome. You might find yourself dragging the drive if the appliance is massive and heavy.

You might find it complicated to drive, especially when crossing bridges or any inclined planes. 

Insulation Strength

Another vital element is the air conditioner’s capability to dissipate heat. It is a must that the product you’re going to buy has the adequate capacity to slow down the heat exchange.

It is vital to consider the insulation strength when deciding to buy the best RV air conditioner. It is essential that heat remains in the unit while on cold seasons and to release it on warm days. 

In this case, you might need a professional’s help to assist you in verifying because the insulation capacity varies among brands.

Ease of Installation

Indeed, you should not leave behind this element in buying an air conditioner for your motorhome because the installation has an additional price, particularly on the window and rooftop types. But of course, most air conditioner companies include this render for free.

But if such assistance is not available in the deal, you can do it yourself by strictly following the procedures indicated in the operations manual. If you’re not confident, just pay extra to avoid further damage if you mistakenly install it.

Types of RV Air Conditioner

Last but not least, you have to familiarize yourself with the various RV air conditioning appliances to determine whether it fits the insides of your van. This consideration matters most notably on the manner of installation, cooling power, and other areas necessary that your motorhome must have first. 

Window Type

This type is the meekest among the air conditioner types. Window type air conditioning appliances are mounted through one of the windows of your trailer van. 

Window types are space savers inside, but you have to give up your view because it is an obstruction. Worse, you have to cut-off portions of your rig if the windows are not big enough to mount an air conditioner.

Luckily, you can buy cute sizes of the present-day version that can occupy only a small portion of your skylight. There are window type air conditioners that are lower than 15 – 20 inches, which register at 5,000 btu or stronger.   

Under Bench

As the name implies, under bench types are installed underneath the seats of your van for camping to make more interior space. Thus, it does not bar you from viewing your windows. 

At the same time, this design works better during cold weather because it allows the warm air to rise and stay above. Remember, colder air is denser than warmer air, so it is essential that hot air stays on top to warm up during cold months.

Portable Types

This type of air conditioner might be the most convenient of all. You can bring it anywhere inside your motorhome, or wherever you go even outside of your rig. Therefore, it does not require that you waive your roof skylight or any window to mount the air conditioner. 

However, models of this type have a maximum power of not more robust than 14,000 thermal rates. You don’t have to worry because most handy models have an integrated airflow system that can blow as much as 320 CFM.

Such magnitude is enough to lower the thermostat of a recreational van with over 500 square feet. Therefore, your motorhome must have a formidable air system to augment what handy devices short in thermal power.

It is required that you consider the dimensions of your motorhome before opting for handy RV Air conditioners. Nevertheless, if you can’t use a portable AC inside your trailer van, you may use it in your bedroom or office. 

Rooftop Type

Without a doubt, being a cooler is the main reason for having an air conditioner. That’s why it is highly recommended that you choose the rooftop model of air conditioner for the trailer van. 

Most rooftop-mounted air-cooling appliances have the average thermal unit of 13,500 to 15,000 thermal ratings. This power register is robust in covering RV sizes ranging from 350 – 450 square feet.  

Literally, Rooftop ACs cool down the inside of your motorhome as the air descends around every space. This design is perfect for a long summer road trip because colder air tends to stay low as it is more substantial than warmer ones. 

Furthermore, there is a low and high profile of this type of air conditioner. Interestingly, there is a rapid increase in the demand for low profile rooftop AC due to being more compact, lighter, and aerodynamic than the full profile version.

However, a high profile variant is quieter than its counterpart as if you’re doing your laundry in the washing equipment.  

Moreover, in general, the rooftop design is not appropriate during cold seasons because warmer air tends to stay on top than denser colder air. Unless your rooftop AC has an integrated window, it will be an obstruction on top, preventing natural light from passing through. 

Ducted and Non-ducted Units

The choice between ducted and non-ducted devices is also considering what type of RV air conditioner to install on your rig. To choose one significantly depends so much on the height and length of the vehicle’s inside to maximize the air cooler.

On the one hand, a ducted air conditioner is more suitable for a bigger and more spacious motorhome because the AC mixes with the airflow system of the van. In other words, a ducted air conditioner is a centralized air conditioning system that reinforces a more refreshing atmosphere inside. 

But, you can’t directly manipulate the temperature emitted by non-ducted RV ACs through remote control. When it becomes too cold, you can increase the temperature by reconfiguring the regulator from a control panel that allows the air to pass through ducts. 

On the other hand, a non-ducted or ductless air conditioner is more conducive to petite campervans with no built-in airflow system. That’s why these types are smaller and lighter that does not require more force to distinguish heat inside.

Besides, non-ducted devices have remote controls, which allows a more convenient configuration of the thermostat. However, simpler air conditioner models tend to have a weaker cooling power and noisier than more sophisticated versions.    

Benefits of RV Air Conditioner

Based on the best RV air conditioner review, you may strongly agree that an air conditioner is a vital appliance. You can’t maintain the ultimate RV experience without equipping your motorhome with the best product. 


The main reason for doing an RV camping is rest and recreation. So, you must experience comfort at the maximum level.

Because most campings happen in summer seasons, you can’t merely rely on natural wind to refresh you. Besides, you can’t control its magnitude, direction, and even its history.

With the best air conditioning device, refreshment inside your RV could not be a problem, regardless of whether the AC has a dual, digital, or manual temperature regulating device, as long as you can reconfigure it. 

Meaning to say, to make your van cold or hot is within the tips of your fingers. Comfort is beyond imagination if the AC has added features like warming, dehumidifying, and airflow system that works properly.

And because RV campings are usually far away, it is also convenient to sleep soundly while on the journey. Traveling such a great distance requires a quiet and soothing atmosphere.

With a good rest and sleep, you can be enthusiastic and fruitful on a fully-loaded camping event. 

Purified RV Inside Air

Fresh nature blowing air is still the best to inhale when you’re camping. But with the ongoing deterioration of the natural environment, this has messed up this timely benefit.

Also, not all camping sites have abundant trees that can make fresh, clean air. Worse, some camping spots have industrial zones nearby, which contribute further to releasing the lousy breath, germs, and other virus-forming agents.

On these issues, the air conditioner inside your RV could only be your only way to breathe in clean air. Most air conditioning appliances have built-in air-purifying and dehumidifying functions to produce fresh air while inside a campervan.

That’s why air conditioning devices are vital in keeping your RV conducive for campers. People stay inside for hours and hours while traveling towards camping or hiking locations.   

Besides, camping should be beneficial to your health and not otherwise. 

Full Recreational Van Experience

Let’s admit it; an RV ride is already a kind of luxurious and splendid experience. Not all people have the chance to get inside it.

First-timers would love to stay inside for the rest of the day, even if they’re not going to a camping site. The amenities similar to a home inside, while going to your destination is a whole new thing for them.

Camping is already an exciting recreation. Going there by RVing exponentially levels up the fun.

However, all these day-dreaming will suck if campers bump into a screwed up RV because its the AC does not work well. It’s like a home without any windows at all. 

In other words, the air-refreshing device could make or break your camping ride experience. Therefore, your only solution is to buy the best RV air conditioner.

Thus, with the fantastic information gathered-up for you, there’s no way you can make a mistake. 

Tips in Maintaining RV Air Conditioner

Owning an RV has already drained a lot of money from the day you bought it and in maintaining it. The same goes for the air conditioner you put in.

Most of the best RV air conditioner products cost from $400 to $500 up to a grand. Therefore, it’s a devastating loss if you found your air conditioning device beyond repair.

For such a point, you must check your RV and everything in it whenever you stop or garage for home, especially your AC.

Other than aging or sudden wreck, corrosion and oxidation are some of the general damages earned by most appliances. These usually begin from nothing-to-worry spots until it has undermined the functioning of the air conditioner itself.    

So, to prevent these from ruining your RV air con, it’s time to open it up for thorough cleaning and overhaul. This process is just like how you clean your home air cooler. 

Dress your RV 

Damages that occur in any RV appliance or equipment comes from the outside. RV travel and destinations are always enthusiastic with lots of fun, risks, thrills, and every bone-chilling encounter.  

Hence, it’s inevitable to keep it clean when you’re traveling, unless you’re crazy enough to hide it under covers while on the road. So your chance to safeguard it is when it is in your garage and not in use.

So, put on a cover for your RV whenever it’s simply parking, and you knew that your stop would take a long while. That simple stuff would somehow prevent any unwelcoming dirt from penetrating your van and eventually infiltrating your appliances and equipment.

This is pretty basic, correct? But, most people, particularly when busy, tend to neglect this fundamentally-sound tip, and they only see the value when their motorhome has become valueless.

Fortunately, RV covers are always available, and companies are ready for this. Blankets and other merchandise are up for sale or sometimes part of the deals when you buy any RV equipment. 

Therefore, for crying out loud, cover your RV when it is just sitting right there in your garage. 

Clean it Up 

Covering your vehicle is just half of the solution, or even less because you can’t park your RV all your life. Why bought it if you’re not driving it or at least let it earn from rentals. 

The fact of the matter is you have to clean it at times. Ironically, cleaning an RV, including the air conditioner, can get dirty and ugly.

For cleaning the air conditioner alone, you have to be meticulous and pay so much closer to the following.

Condenser Coils

Firstly, you have to pay special attention to the condenser coils. You need to remove the metal cover, unplug the device, and wipe every inch properly. The loops play an essential role in the refrigeration process, which allows the dissipation of high temperatures while cooling the indoor. 

Folded Fins

Secondly, bent fins are not okay because they trap the hot air inside. Therefore, fins are fully capable when straightened so that the blazing air can dissipate properly from the condenser vapor. 

Fan Motors

Thirdly, see to it that bearings of fan motors or blowers are not stuck by regularly oiling it. This part is vital in improving the airflow, which dehumidifies the RV internal environment. 

Now, for you to do all these properly, you have to remove the air conditioner from where it’s mounted and disassemble it. Ensure to keep every part around when you dislodge the equipment.  

After cleaning, mount it again, check if the device works, and improve the airflow. Sad to say, the worst thing to happen is to find the AC not working after returning. 

Plus, the ease of cleaning depends upon the type of installation. Portable appliances can be simple, but not for window types, and especially, for ducted rooftop types. 

Nonetheless, the best way to maintain your air conditioner is to keep it clean. After all, you can hire professional cleaners to save your RV air conditioning device from any untoward incidents. 

Let it work within its limits.  

It does not matter if your RV has the best air conditioning system. If you let it work too much every time, then it is bound to fall eventually. 

Primarily, if the manufacturer has engineered the RV AC to room up to only 350 sq.ft, don’t install it in your motorhome with 500 sq.ft ample space. In doing so, you are forcing your equipment to work on a maximum force all the time.  

The same problem with worse impact can happen when your RV doors or windows are opened while your air conditioning system is on. The air blown will just escape, and there is no way your RV can cool down inside when the barriers are up. 

If it is complicated for an air conditioner, with a standard thermal rate, to room-up beyond 400 sq.ft, what do you think is its chance of even fanning an open space? 

By doing this, you are either letting the AC age faster, make it suck more fuel, or discharge your RV more often. In any case, it could be your loss.

The bottom line’s thermal capacity of even the best RV air conditioners only works effectively within its limits. Thus, this is another useful tip in maintaining your AC. 

Always Check   

You need to check RV from time to time. That goes similarly to the air conditioning appliance. 

When you buy, you meticulously see through every detail to convince yourself that you have gotten the best air conditioner. So, you apply that level of scrutiny when you hear unpleasant sounds from your appliance, or when you have a long stop, and when the RV is not in use.

Here are the things you need to be particular about your device:

  • If there are cracks
  • Clogging dirt or debris
  • Tarnished metal parts
  • Slight corrosions and oxidation
  • Peeled wire coating or exposed live wire
  • Bent fins
  • Stuck motor fan gears

Luckily, you can mitigate all these with a thorough cleaning, repair, or overhaul. Thus, early detection means swift solutions.  

You’ll never know what hit your RV air system if it malfunctioned when you don’t give so much care and attention. However, don’t be crazy like anxiously checking it all the time, at least do it on a regular schedule like every month or two. 

Frequently Asked Questions

Amidst the voluminous discussions above, there are some issues left unsolved. We collected some and shared some insights about it.

Let’s hope that some of your queries are like the ones here. If not, comment down below, and we will graciously accommodate you. 

What is an RV Air Conditioner?

RV Air conditioning units are devices that look almost like what you use to cool down your bedroom but works similarly as a refrigerator. The AC units are either mounted on the roof, windows, or sometimes, hand-carry. 

But the main difference is how it works. House and office air conditioning units consume power from electricity generated by water, sun, or wind. However, the RV AC source of energy is either the vehicle’s fuel or battery charge. 

Thus, some RV owners upgrade their vehicle’s power generation by installing other equipment to get renewable energy. As you observed, most RVs have an AC spot on roofs, and most units are inclined to rooftop mounting. 

If you’re using solar or wind, you have panels over the roof, and it can efficiently conserve energy. Inside the van, ceiling installed air conditioners can cool down faster because the cold air is heavy and can swiftly descend. 

Furthermore, RV AC units are not for summer alone, but some designs also work efficiently on colder days as warmers. Most aerodynamic air conditioning systems have an optional heat strip or a heat pump to make the warming process.

Moreover, other air conditioners have dehumidifying functions that freshen up the inside atmosphere. This operation makes the RV more conducive for longer drives and tours. 

Thus, with the help of the air conditioner, campers can inhale clean air. 

After all, RVing has a bag of tricks for extreme activities and events. Thus, air conditioning appliances can significantly increase the level of comfort, rest, recreation, and satisfaction. 

How To Install An RV Air Conditioner?

Ensure that you have considered the appropriateness of the air conditioner to your RV, especially the size, type, and density. When you do, follow steps in the manual to install your appliance safely.  

Don’t forget to turn off the vehicle before you proceed.

  • Prepare the spot where to mount the unit, whether a window or a roof hole. Just see to it that you had made the adjustments when you considered the dimensions of the equipment. 
  • Aside from the dimensions, consider the energy source, wires, and a spot where you can place the ducts. The spot must be strong enough to hold, support, and unmove your appliance.
  • Mark the holes and segments where you’re going to drill screws.
  • When the hole is ready, unpack the wires, organize, and reconfigure it according to the manual’s instructions. 
  • Mount the air conditioner right above the roof or outside of the windows) tighten the bolts with screws as marked. Inside the van, install the locks for the ceiling or windows, use sealants to cover at certain portions where the metal and the device meets. 
  • Install the wires through the proper connections, as indicated by its colored coating. Observe extra precautions in doing this because you might cause an electric shock or explosion if you miss corresponding wires.  

To avoid messing up big time on this, might as well hire a professional electrician to do the job. If that person misses, at least someone will pay you instead of for you to recover the damages.

Nonetheless, when everything is in order, you can test the air conditioner.     

Can I run my RV air conditioner on battery power?

Of course, batteries can do fireworks for your RV air conditioning equipment. But the question is, how long can it last?

It means you need to fill in the energy gap by using other renewable sources. You may use wind, solar, hydro, and anything that could safely work to load the batteries.

But the thing is, battery load should not be the primary energy giver to run your appliance. Unless it’s a portable one, such a type is perfectly conducive for battery power.  

Can I heat my RV with the air conditioning appliance as well?

You usually can’t use an ordinary air conditioning appliance as a warmer. But, if it has a heat pump or heat strip, then you can. 

Therefore, you have an aid during colder months. However, the warming functions of RV ACs cannot substitute the capacity of a legitimate heater.

How To Charge my RV Air Conditioning appliance?

RV travels can get longer than expected, and at some part, your air conditioner’s energy will run out of supply. Then, you need to recharge to keep the tour going.

That’s why you need to be careful enough to do it. So, take into account the following steps as you observe the user’s manual of your unit. 

  1. Decrease the energy level of the unit by lowering the electrical breaker. 
  2. Prepare the appropriate refrigerant that fits and compatible with the unit.
  3. Open the lid of the unit and unscrew the shroud to ensure the uninterrupted flow of current.
  4. Replenish the depleted refrigerant with the new one. Do this slowly and accurately to avoid spillage. 
  5. Check if the temperature of the unit is 20 degrees colder than the RV internal surrounding.
  6. Once done, turn on your unit if it’s working better. 

How to solve Frost Formation?

Frost formation on your air conditioner’s vent is an indicator that your device is producing cold air at a very slow airspeed. But, you don’t have to mind this much because there are plenty of ways to eliminate frosting. 

You can turn the unit into a heater set to melt the ice. However, this is pretty tricky and risky because it might spit the ice and fall on something like wire or paper.

Also, it can utilize the fan setting to avoid spitting and just melt the ice gradually. However, to put certainty, just clean the unit for good to wash away the frosting, including some dirt.  

How to silence my Noisy RV Air Conditioner?

You might irk tremendously when your RV air conditioning unit produces loud and proud buzzing while traveling. It significantly affects the level of comfort you must be enjoying at the moment. 

Furthermore, a noisy RV air conditioning appliance means a lot of things to check inside the device. Thus, here are some things that you need to check when your AC unit begins grumbling. 

Aging RV Air Conditioners

Expect your air conditioning unit to get rusty when it is way too old. For your information, a secure brand new unit may averagely last for about 5 – 10 years. 

However, most manufacturers do not vouch for that long, as evidenced by a 2-3 year warranty on their products. But, depending on how you maintain the unit, it can last longer.

Nonetheless, over-extended usage contributes a lot to the decibels it produces over time. If you can’t bear the disturbance, you can still do something about it (see further discussions below).

When those remedies do not work, and you just accept that your AC unit is beyond repair, just replace it with a new one.

Clean the Fan Blades

It will make noise for sure, if there’s anything, dirt or dust build-up, on the blades of your fan blower. This might sound like a broken washing machine at the beginning 

When it goes so long, it might sound like a water pump motor and it’s horrible.

In that case, just wash and clean the edges properly. Do that without moistening the electrical components, particularly the wires. Or else, you might knock off your air conditioning device for good.  

Ramshackle Rubber Cushions  

Torn and worn out rubber cushions are another cause of noise produced by your air conditioning unit. Cushions are the ones catching and absorbing the vibrations created when the unit is running.

Over time, dilapidated rubber absorbers can’t withstand the vibrations. Therefore, it needs repair or replacements. 

Oily duct tubes 

Ducts filled with so much grease can be a cause of noisy RV air conditioners. Just rinse it or change it will do great work to silence your unit.

High-speed Fan 

You can silence your RV air conditioning device when you lower the speed of the fan. The rapid rotation also produces some annoying decibels. 

Sloppy-Fixed Components

Shaking joints, bolts, or gears that were loosely attached or screwed generates uncomfortably sounded noise. When this kind of grumbling occurs, it means a horrible danger. 

More than the irritating sounds, it also signals that your AC unit is about to fall. That could be the most terrible incident to happen. 

Proper Maintenance

Combining all the tips just means one thing: always to do a regular RV air conditioner maintenance. As previously discussed, an uneasy sounding AC unit means that there is something wrong with the appliance. 

Therefore, by regularly inspecting your device, you can save a lot of potential damages.

Let the Silencer Do Wonders 

Finally, if you are confident that the air conditioning device is in its best shape upon careful inspection, just use a silencer. There are some varieties of these that the manufacturer also sells.

This accessory can significantly reduce the noise by 8-10 decibels. Such a decrease is massive enough to make you comfortable inside your RV refreshing.   

Which size of the Air Conditioning unit is best for my RV?

Let us remember that the British Thermal Unit is the nominal indicator to determine the size of the AC unit that fits well for your RV. In other words, this pertains to the capacity to fill an entire RV with cold air. 

That goes similarly to the refrigeration rate as determined by the cubic feet per minute CFM. This translates to the airflow system, which improves the room temperature. 

Concerning that, the thermal unit refers to the amount of energy your unit can produce within an hour. This means the size of the best RV conditioner to choose must be based on the dimensions of your RV.

For example, RV air conditioning units with less 8,000 btu is just suitable for vans as small as less than 300 sq.ft. For RVs with less than 500 sq.ft, you need as strong as 10,000 – 13,000 btu, and as much as 14,000 – 18,000 btu for 1000 sq.ft full motorhomes. 

However, these thermal measures vary as the season changes. Of course, you don’t need your unit’s freezing capacity when it’s winter, unlike during summer vacations. 

Anyway, a lot of variables affect the capacity of an AC unit to room-up an RV.  

Why Is My Camper Air Conditioning Running But Is Not Cooling?

It is absurd to find out that your RV air conditioner is not functioning as a cooler from the time you leave until you reach your destination. Hence, it also means a lot of things when this problem occurs. 

For this reason, you need to conduct some assessment procedures to identify what’s causing this seeming malfunction. Indeed, any of these could be the culprit, and you can successfully diagnose and treat the problem.

Cooling Capacity Mismatch

Let’s go far enough; one of the possible reasons why it seems that your air conditioning unit is not working is because it does not fit. Your RV could probably be way too big for the air conditioning appliance’s thermal unit. 

To illustrate further, it is like your bedroom should have a window AC with two hp, but install a device that can make only one hp. That power difference may not be able to chill down your room as well as your RV. 

However, the nominal capacity may not always be an absolute thing. If the room temperature improves by 20 degrees colder despite the low thermal rating, then it is working. 

Meaning to say, covering a room with cold air needs time. It’s not an instant change in the chilling or warming rate. 

Congested Fins

As previously mentioned, straightened fins supplement coldness in the air blown by the RV air conditioner. Therefore, when your AC unit is not chilling down, it could be that you have bent fins. 

Usually, dirt and dust that builds-up inside are causing the clogging. So, by washing it away could decongest it and release an excellent airflow.  

Full Filter

Filter problems are similar to fin issues when clogged. Clogging happens when the foam of cobwebs have overwhelmed it or through the frosting. 

Fortunately, some merchandise includes a washable filter. You can clear it up with water and soap.

If cleaning does not solve the congestion, just buy a new one. It’s not that expensive compared to purchasing a new unit. 

Uncleaned evaporator and blower

To ensure that your RV air conditioner can maximize its power, complete the cleaning process by washing the evaporator and blower. When this is crystal clear, nothing could bar the air from flowing out smoothly. 


Aside from cleaning some vital components, you might also want to check if there are leakages somewhere. The leak might be grease, hot or cold air, and intake or exhaust air are combining.

You can say it’s a minor issue when hot air leaks because this air comes from the gaps between the roof and the ducts. Remember, inside these ducts are the bulging wires, and you can use electrical tapes to seal.

However, when it is the cold air that’s leaking, that could be a significant problem. It means that the cold air is just roaming from the duct to the roof space.

 So, inspect if the duct’s seals are intact to avoid the colder air from escaping.

Furthermore, the problem could get even worse if the air from the intake and exhaust mixed-up. When this occurs, it means that the sky is not flowing through the RV inside due to the failure of the foam ring.

To solve this, you have to seal the air pathway between the intake and exhaust. Then, you can free up and divert the trapped air back to the interior again.  

Lastly, when the airflow inside the rig escapes via holes produced by external oxidation. So, always inspect including the coating of your RV.

Therefore, check these leaks with flashbulbs by aiming it through sides. The good thing is that any foam seal can repair all these kinds of leakages.

Give the best care ever

To keep it fresh and refreshing, observe the best maintenance you could apply in the long run. Begin with regular inspection, cleaning, oiling, and anything that could delay the damages.

After all, once you begin RVing and using the air conditioning equipment, damages might occur sooner or later. Maintenance is just a way to delay it with style. 

What are the best brands?

The answer to this question is glaring as bright as the sun. Based on our review of the best RV air conditioning devices, we have seen the same names. 


There is no doubt that this brand manufactures the best equipment for RV. As far as our list is concerned, ⅓ came from Dometic. These are the Brisk Air II series: B57915 and B59516; the Penguin II series 640315 and 651816; and Sanitation 143002P041.

Most of their units have standard and above thermal units, made of durable materials, and convenient for installation. Plus, you can buy their groups, with all these qualities, at justifiable prices.   

However, high power consumption is one common observation among their creations. But, it is reasonable since most of their units are robust air conditioning units. 

Anyway, you cannot go wrong with this brand because they have done all these since 1919. Therefore, they already have essential credibility. 


Airxcel deserves to belong in the best brands of the best RV air conditioning. Their creations are also formidable coolers just like Dometic, such as the 08-0080, 08-0079, and 08-0212.

Aside from that, their AC units can serve as air chillers and warmer, and dehumidifier. Surprisingly, with these functions, Airxcel devices do not use so much energy supply. 

They are also famous for durable and featherweight made units that are easy to install. 


Meanwhile, Atwood RV equipment and appliances, particularly the AC units, are famous for their air conditioning capacity. Most of their appliances have a registered nominal strength of above and maximum standards. 

Moreover, the energy efficiency and impervious structures are their best RV air conditioner attributes. It does not matter whether most of their works are heavy-lifted as long as they can make your RVing comfortable. 

In addition to that, longevity is also their league because Atwood has been in the industry since 1909. Can you imagine, this company has thrived through world war I and maintained its game at present.

With that long history, you can understand the mindset and philosophies behind in creating their products. It is impressive how they have evolved throughout the century. 

ASA Electronics

Last but not least, ASA Electronics have their fair share in the best RV air conditioning equipment’s premium brands. Although there are a couple of ACM units in the review, they are still among the best buys.

They are famous for their not so heavyweight products that are easy to install and with sturdy bases. These good qualities are testaments to their greatness and adaptation to the needs of the market. 

ASA Electronics has been there for a while since 1977. Thus, you need not worry about putting your money here.  

How much does an RV Conditioner cost?

You can purchase typical air conditioning units for less than $200. Some of these products may not be even suitable for RVs. They are made for bedrooms and offices, which are usually window-mounted. 

So, don’t expect these units to do wonders in your RV regularly. Not to mention, cheap units are irritably noisy.

Luckily, there are RV air conditioners with more substantial capacities, which might cost around $200 – $500. Commonly, half a grand worth AC units are handy, which can be very versatile and does not have installation issues. 

However, this effectively works on small to medium RVs while using standard thermal units and CFM. 

Finally, the most expensive AC units are those with massive sizes and room coverage. All of these products are known for the best performance, durability, and other sophisticated attributes.

Of course, these products come with atrociously high prices ranging from over $600 to a grand. Nonetheless, expect to experience almost freezing point when you get in your RV having one of these AC units. 

To sum it up, you may consider your air conditioning device as an asset and a well-invested project.

Do you need an upgrade?

Honestly, it depends on how you are going to rate the performance of the current product installed to your RV. If you’re satisfied, why change?

Unless you’re into the rental business, your RV must provide the most awe-inspiring experience campers can ever imagine. The first step is having the best RV air conditioner refreshing your motor home’s environment.

How intense should an RV Air Conditioner be?

Allow at least 30 minutes to pass when you turn on the air conditioning unit. By that time, the room temperature must decrease by 50%. That is cold enough to acclimate your body. 

Hence, if your AC unit can’t reach this level, you have to pay close attention and subject it to a thorough inspection. Something could be wrong and needs significant adjustments or repairs. 


Indeed, looking for the best RV conditioner may not be that easy at all. It’s way too complicated as if you’re buying a smartphone or any mobile device. 

Precaution and precision are the necessary tools for fully inspecting each product. 

You can’t go wrong by choosing sloppy or cheap ACs for your RV. You have to consider the high performing and the best profile concerning the cost and the benefits.

You need to study everything based on the thermal units, cubic feet per minute, materials used, ease of installation, density, and variables. In other words, everything is essential.

The competition for the best products is extremely tough. All the products possess the particular attributes you could ever desire for your RV. 

It so happens that the qualities are all over scattered in each brand. How you wish that all the strengths and remarkable feats are just in one product.

Regardless of how much you’re willing to pay, for as long as the master traits are there. That’s the case if you’re wealthy enough. 

However, those campers with a low budget wanted the best out of the most affordable products. They may forgo other areas that have no relevance to their needs.

It does not matter whether you can pay for expensive or cheaper products. The most important thing is the air conditioning technology does its job well in chilling your RV. 

Nonetheless, on your part, it could be more comfortable deciding. With helpful information, you can avoid deception or hype.

You can look closely and pick the best RV conditioner for your own sake and enjoyment.
