Best RV Air Conditioners

So you really want to get a nice air conditioner for your rig but afraid that you might waste money on less than ideal products? Then you come to the right place as down below, you would be introduced to some of the finest A/C models for RV nowadays. 

1. Dometic Brisk II Air RV AC (B57915.XX1C0)

Dometic Brisk II Air B57915.XX1C0

  • BTU: 15,000
  • Volt: 110V
  • Wattage: 2,800W

Why This Is The Best 

Compact, aerodynamic and powerful, Dometic Brisk II Air (B57915.XX1C0) is the best RV air conditioner on the market in terms of all-around performance. As the Dometic unit possesses a modest profile, it’s a good match of recreational vehicles that have limited room. Thanks to the use of lightweight materials in its construction, Brisk II Air (B57915.XX1C0) facilitates installation as well as maintenance in most cases.

As the A/C from Dometic features a center discharge air delivery, its airflow and cooling efficiency prove to be superior to the average products. While the unit is strong, it remains fairly quiet in operation due to the presence of the noise-dampening brackets. As a result, you can enjoy cool airs and have peace of mind on the road if you get Brisk II Air (B57915.XX1C0).

For post-purchase support, RVers would receive a 2-year Protection Plus warranty once they purchase Dometic Brisk II Air (B57915.XX1C0) which is nice. However, keep in mind that the warranty is going to be voided if you use the unit with household thermostats.  

Easy to install, works great.

Finally killed my 13,500 btu Dometic ac unit last summer (12 years old). My RV is large (35 foot travel trailer) and on hot days it would run constantly. Upgraded to the 15,000 btu unit. Really easy install, less than 30 minutes start to finish. Blows ice cold and operates properly. I thought I would be spending $1000 and busting knuckles for four hours, but no, less than $600 and 30 easy minutes. I hope I can get 12 years out of this one.

2. Airxcel Mach 15 RV AC

Airxcel Mach 15
amazon cta


  • BTU: 15,000
  • Volt: 120V
  • Wattage: 1,800W

Why It’s An Editor’s Choice:

Featuring a 1/3 HP fan motor, which is the largest one used in modern RV air conditioners, Airxcel Mach 15 is essentially the strongest RV roof AC unit available for purchase. With the ability to deliver cool air an impressive rate of 320 cubic feet a minute, the model from Airxcel is widely called the best RV air conditioner regarding power by multiple RV air conditioner reviews. The streamlined designs of the unit further improve its cooling efficiently in conventional RV configurations. 

Packing an excellent combination of all-copper tubing and gas-flux brazed joints, the Airxcel AC often maintain peak performance for a long time. As the unit incorporates large evaporator/condenser coils and raised lace fins, it’s able to dissipate heat effectively and efficiently in challenging weather conditions. Being a high output model, Mach 15 is the best RV AC unit for ducted installation but with a ceiling assembly kit, it shall perform admirably in non-ducted setups. 

Designed for the standard 14 x 14 vent opening, Airxcel Mach 15 could be adapted to most recreational vehicles so RVers don’t have to worry about compatibility. As the unit could work existing Coleman thermostats, you could save a good deal of money if you get it as a replacement A/C.

I have access to a forklift at work, so getting it up on the rooftop of my 96 Gulf Stream was easy. Replaced a worn out 13,500 btu Coleman Mack with this unit. At first I thought this would be an easy direct swap, but when I got this into place I realized that not only was the bolt pattern different by about 1.5 inches on each corner, it required smaller bolts than the old unit. (1/4 vs 3/8). But after a trip to the hardware store and some creative fabrication work on the ceiling bracket I got it bolted firmly into place. The wiring plug was a perfect fit. We’ll see how well it does this summer, it does move a lot more air through the ducts than the old one. 😊
Update: This ac unit is awesome! It easily keeps my 32 foot Gulf Stream cool parked in direct sunlight on a hot day. Both my 5500 watt Onan generator and my Champion 4000 watt inverter generator easily start and run this unit. Very happy with this purchase!

3. Airxcel Mach 3 RV AC

Airxcel Mach 3

  • BTU: 13,500
  • Volt: 120V
  • Wattage: 1,075W

Why It’s An Editor’s Choice

For RVers that care about the electricity bill, Airxcel Mach 3 is arguably the best RV air conditioner money can buy. Being able to offer a lot of cool airs without drawing too much power, the Airxcel model is the most efficient RV air conditioner nowadays. Similar to its cousin (Mach 15), Mach 3 also possesses a 1/3 HP fan motor which provides it with a splendid flow rate of 320 cubic feet per minute. Aside from cooling the interior of the vehicle, the unit could generate heat if fitted with the optional heater assembly.

Because of the built-in shaft, the air conditioner from Airxcel is relatively safe from damages caused by outdoor elements. With the incorporation of the plastic drain pan, the unit skillfully prevents and eliminates corrosion. The shroud that comes along the model also features protection for condenser coil so overall resistance is truly top-notch. If necessary, it’s possible to mount Mach 3 directly to the bulkhead to address angle distortion of the blower wheel.

To speed up the setup process and reduce cost, Airxcel Mach 3 could reuse existing ceiling assembly as well as thermostats. The model still needs to settle which means you should refrain from leaving it on for too long at first. 

We bought this to replace the original rusted roof top air conditioner in our 1969 Avion T28. It was very easy to install once we got the old unit out. I lifted the unit and my husband up in the bucket of his tractor and he was able to easily maneuver it into place. The wiring snapped together and the foam seal worked great. It is a little bit loud, but I like to run a fan at night to help me sleep anyway. It cooled our 28 foot camper and definitely eliminated the humidity. We are very pleased.

4. Dometic Brisk II Air RV AC (B59516.XX1CO)

amazon cta


  • BTU: 15,000
  • Volt: 110V
  • Wattage: 2,800W

Why We Love It:

If you like Dometic Brisk II Air (B57915.XX1C0) but want more cooling power, Dometic Brisk II Air (B59516.XX1CO) is for you. Boasting a BTU rating of 15,000, the unit from Dometic is capable of satisfying the cooling needs of RVers traveling in the middle of the summer.

This unit works well. Read the instructions well. They say to hook it up to electricity before you mount it on top of your trailer. This way, you can see the fans turning and inspect for any rubbing that results from jolts during shipment. This unit needs to be light weight to put on top of a camper or box trailer. Do not expect a light weight unit with a light weight frame with a compressor and fan motor mounted to it to arrive in perfect condition after UPS shipment. The frame base metal will be bent due to shipment. You will need to bend it back and make sure both fans can turn freely before mounting this on top of your camper.

Also, if you are mounting this to a unfinished box trailer with no interior, you will need to fabricate at least a 1/2″ thick sheet of plywood to facilitate getting the conduit/wiring to the unit. The control panel needs to mount to a flat surface with some small wood screws. The control panel has no openings for the wiring to enter. The control panel separates the in and out ductwork, and must be used as designed. Your camper or trailer needs to have the wiring to the 14″ by 14″ opening in such a way that there is a flat wood surface inside the camper/trailer for the control panel to mount to. Some slight fabrication will be needed to mount this to a camper / trailer where there has never been a unit before.

Shopping For The Best RV Air Conditioner: A Few Criteria

Different RVers experience different issues so it’s only natural that people have conflicting opinions regarding the best RV air conditioner on the market nowadays. Nonetheless, everyone agrees that if you want to get your money’s worth, it’s essential that you focus on certain qualities of AC. 

BTU (British Thermal Unit) Rating 

To determine if a particular air conditioner is strong enough to keep everything cool, all you have to do is to check its BTU rating. The higher the BTU rating, the stronger the cooling power. Take the space inside the interior of your recreational vehicle into account to decide just how much BTU you need. You could use the following space BTU estimates as references. 

  • From 100 to 300 square feet: Between 5,000 and 7,000 BTUs
  • From 300 to 550 square feet: Between 8,000 and 12,000 BTUs
  • From 550 to 1,000 square feet: Between 14,000 and 18,000 BTUs

In the case you have specific demands, feel free to go for higher BTU ratings.   

Size And Weight 

While searching for the best RV air conditioner, size is something that you must keep in mind at all times. For models mounted on the rooftop, the size of the unit is going to affect clearance height and overall drag. For portable models, the size of the unit determines how much space it occupies in the interior of the vehicle. In addition to that, it’s widely advised that you consider the weight of the unit as that often influence installation, maintenance and so on.  Once again, think about the profile and layout of your RV to make wise choices. 

Ease Of Installation 

Technically, you could always drop by an RV workshop and hire professionals to take care of the installation for you. Still, it’s worth noting that you already paid lots of money for the AC, why create more expense? So if possible, prioritize products that have plain, straightforward installation. AC like that would let you set up everything by yourself which save money. To ensure that the installation proceeds smoothly, it’s essential that you get all the parts from the same manufacturer. 

Noise Level 

Virtually every air conditioner these kinds of days produce noise in use but some prove to be quieter than others. In the case you want to optimize your travel experience in the outdoors then you should opt to get an AC that runs silently. All in all, it’s rather pointless to have a cool interior only for the AC to keep disturbing you with its operation noise. Because of that, if you want to get the best RV air conditioner for your rig, remember to check the noise level before making purchases. 


If you happen to come across a couple of AC models that have comparable performance, consider checking the miscellaneous. For example, units that come with an integrated heat pump would be more versatile compared to those that come without. Heat pump-equipped models could maintain a cool atmosphere in hot climates and provide warmth if the weather gets cold.  Therefore, air conditioners with a heat pump tend to be highly sought after by RVers that travel around the year. 

Rooftop Vs. Portable: Which Type Of A/C Is Better

Nowadays, the market offers two types of air conditioners for recreational vehicles: rooftop and portable.

RV AC reviews
  • Rooftop Air Conditioners: As the name suggests, models of the type sit on top of the roof of your rig so they don’t take up space in the interior. On the other hand, an RV rooftop air conditioner often reduces the amount of natural light available to recreational vehicles. In addition, because these air conditioners reside on the roof of your RV, RVers should be careful while passing through bridges, overhang and so on.  
  • Portable Air Conditioners: Unlike the fixed rooftop models, portable ones would be able to move around without much difficulty in the interior of your rig. However, portable air conditioners often have limited cooling power so they could only cool a single room in most cases. Furthermore, if you intend to get portable AC then it’s necessary to think about room inside your rig.    

Maintaining RV Air Conditioners:  A Couple Of Tips And Tricks

Having the best RV air conditioner is indeed nice but if you want to get the most out of it, you must look after it. Fortunately, you don’t have to be an expert to perform basic AC maintenance. Needless to say, for safety reasons, cut the power to the unit before doing anything.

  • Wipe The Coils: To access the evaporator coils, you need to remove the metal cover, unplug the control board and take out the freeze sensor. Normal household cleaners should be adequate but for maximum effect, consider using purpose design products.  
  • Straighten The Fins: Air conditioners that have bent fins tend to have restricted airflows which make them become less efficient.  So every now and then, grab a specialized coil fin comb and proceed to straighten the fins of your AC.
  • Oil The Motor: If your AC features bearings, it would have oiling ports so all you have to do is to refill the ports. On the other hand, in the case your air conditioner uses sleeves, you have to oil the shaft in between the sleeves and the housing.

Note: Beside periodic checks and maintenances, it’s strongly recommended that you cover your AC during off-seasons to prevent dirt, dust, debris and so on from getting in.

FAQs About AC For RV

Is it possible to run air conditioners on battery alone? 

Technically, you could run your AC using solely battery power but you must carry out quite a few preparations. Namely, you need solar panels, generators, additional batteries and so on to make it work. Unless you happen to be a full-time RVer, it’s often unnecessary to set up your rig like that.

So all A/C models should fit all recreational vehicles? 

In most of the cases, air conditioners for RV on the market could fit the average vehicles without requiring modifications. All in all, just check the size of the AC vent opening, calculate the ideal BTU rating and get the unit that suits you.

The air conditioner in my rig is working fine. Do I have to upgrade it? 

If you feel that your current AC is sufficient to keep the interior cool then feel free to keep it for the time being. Still, if your air conditioner is an outdated, box-like model then it would be wise to look for replacements. Air conditioners like that create a lot of drag on the road which worsens the fuel efficiency of your vehicle.

What are the best brands of A/C for RV?  

If you know for certain that a particular AC model is of good quality then you don’t have to care about its brand. But if you want to play it safe and get your air conditioner from reputable manufacturers then keep an eye out for units from Dometic, Coleman, Atwood and so on.
