High-quality engineering makes this model a resistant powerhouse: the motor is fixed in relation to the blower and is mounted directly to the bulkhead, allowing the wheel to turn freely and blow straight down at no angle.

The motor’s shaft is sealed to protect it from damage and the elements, while the shroud is secured with corrosion-resistant stainless steel truss head screws. A plastic drain pan further bans corrosion.

All copper tubing and gas-flux brazed joints ensure a long lifespan and dependability. The system is further optimized for heat dissipation with large evaporator and condenser coils with raised lace fins.

Even under high temperature, in thick humidity and sweltering conditions, the air conditioner will start easily to deliver cold air.

With a high output, it’s your best bet for a ducted installation. The only knock on the Airxcel Mach 15 is it is noiser then the other RV AC s on our list.

It’s compatible with standard 14″ x 14″ vent openings. If you want a non-ducted installation, you’ll need a Coleman ceiling assembly kit, which is available separately.

For the non-ducted installation, you can also install a heat strip for warm air. The Airxcel Mach 15+ RV air conditioner is available in white or black and installation is fairly easy.

Despite the minimal weight and dimensions, it has a strong performance and delivers 15,000 BTUs of cooling thanks to a powerful quiet motor and fan. It offers sufficient cooling capacity for most RVs.

Compared to previous models, Dometic has greatly improved the Brisk II with reduced weight and increased air flow. It is one of the smallest rooftop models available and it fits 14 x 14 standard air vents.

With a stable base pan and a rigid, aerodynamic shroud, you don’t need to worry about durability or drag and reduced fuel efficiency. Strong motor brackets, foam housings and sound dampening keep vibration and noise to an absolute minimum.

Light high-tech materials such as expanded polypropylene can withstand the stress of rough travel, dust and heat. With reinforced screw holes, you can rely on a safe installation. Insulation and a center air discharge optimize airflow and cooling capacity so no cold escapes.

The Dometic Brisk II unit as it comes is only for cooling. If you want heat for your RV, you will need the Dometic Brisk 2 Heat Strip for a non-ducted installation.

For operation, the Brisk II requires an air distribution box (ADB) for a ducted install or a thermostat (both are not included).

It’s compatible with the Dometic Universal ADB, Dometic Return Air Grill, and the Dometic Single Zone LCD thermostat or Comfort Control Center II thermostat. The model is available in white and black.

The Dometic Brisk II offers amazing value at a reasonable price and is a powerful and reliable RV air conditioner with specifications and compact dimensions that are hard to beat.

How to Choose the Best RV Air Conditioner – Buyers Guide

An RV air conditioner provides comfort in your vehicle and helps keeps the air clean. It’s constructed to withstand vibration and adverse weather conditions while taking up less space than regular AC units or portable ones.

You’ll need to pay attention to the installation type, the capacity, electricity, as well as size and weight.

Best RV AC Unit

Cooling Efficiency

For a consistent cool in your vehicle, the three models we have reviewed can provide 15,000 BTU per hour. That is more than most pre-installed models which tend to stop at 13,500 BTU.

In terms of air output, the Coleman model is the most powerful one and is recommended for larger vehicles and ducted installations.


Regarding the size of the AC unit that is mounted on the roof, you’ll want to consider wind resistance and vehicle clearance.

All three models in our selection are shaped aerodynamically to reduce drag, but pay attention to the height if your vehicle has limitations, for example for parking in a garage.

Then there is the size of your RV and the area you want to cool. One AC is enough to regulate the temperature in the cabin and sleeping area, but for longer, larger vehicles, you might need to install an additional unit.

Also verify that the A/C doesn’t exceed the weight limit for the roof of your RV.

Type of Installation

When deciding on a ducted or non-ducted installation for your RV air conditioner, consider the existing ducts and air distribution in your vehicle.

If there is an air distribution box already or you want the cold to quickly flow to different party, a ducted version is for you.

A non-ducted unit might be easier to install, and it’s also sufficient in situations where you mainly want to cool one area and the unit will sit almost directly on top of it, i.e. the cabin or the bed.

How to Install an RV Air Conditioner

This video shows installation of a Dometic Brisk Air, the procedure is similar for installing most any brand.

Installing an RV Air Conditioner

Heating Use

All three models are for use in hot climates to cool things down. For year-round use in cold weather, they can be upgraded with a heat strip to blow warm air as well. The Advent Complete air conditioner features easiest upgrade as it’s a plug-in installation.

Power Consumption

An air conditioner is among the most power-hungry appliances you’ll have in your RV and therefore requires a generator to run. Look at the wattage each unit require and compare it to what your existing setup can provide.

If you have don’t yet have a generator, make sure it can power all the appliances and devices you want to use at the same time – you’ll be looking for a model between 3,500 W and 5,000 W.

Ease of Installation

In most instances, installing an RV air conditioner does not pose a big hurdle and you can simply work off the provided instructions. Things become more complicated when combining parts from different manufacturers or customizing an existing system.

As far as maintenance is concerned, follow the recommended procedures for cleaning. Typically this only requires changing or washing filters as the unit itself is sealed.

FAQs About RV Air Conditioners

Q: Can I also heat up my RV with an air conditioner?

A: As they come, all of the models above only deliver cold air. Yet all of them can be equipped with an additional heat strip, which you’ll need to purchase separately. This allows the unit to suck in fresh air and heat it up electrically instead of cooling it down.

Q: What is the difference between a ducted and non-ducted installation?

A: All of the RV air conditioners we’ve reviewed feature a box that is mounted onto the roof of your vehicle. It contains consists of a base pan, which houses a condenser, compressor and blower, and a shroud to cover it up.

In a ducted installation, the roof unit connects to ducts inside your RV that distribute the air and you control the settings with a remote or wall thermostat. An air distribution box (ADB) typically forms an interface between the AC and the ducts.

Depending on the size of your vehicle and duct installation, different parts of the RV could require their own roof unit.

A non-ducted installation is more simple as it’s basically an AC sucking in air on your roof and blowing it out cold at the bottom, that is from the ceiling. A control unit (also called ceiling assembly) allows you to set the temperature.

Q: What does the term BTU indicate?

A: BTU is short for British thermal unit. BTU per hour is used to express the power of heating and cooling systems such as air conditioners.

A higher value indicates a more powerful output. 1,000 BTU per hour are roughly equivalent to 293 W, so a 15,000 BTU/h model has an approximate output of 4,500 W.

Q: Do I need additional hardware?

A: If you are replacing or upgrading an existing rooftop unit with one of the models above, you will not need additional hardware if the new model is compatible with your installation.

A ducted installation might require a thermostat or air distribution box, if you don’t have these already. A non-ducted installation needs a control unit. The Advent Complete Air conditioner is an exception and already includes the ceiling assembly kit.

Any AC requires a good deal of electricity, which should not be a problem when you’re stationed in a campground environment where you can get a hook-up.

On the road and in the wilderness, you’ll have to rely on a generator – which you need to bring in case your vehicle isn’t already equipped with one. Make sure the generator can deliver enough power for your AC.

Q: Does an RV Air Conditioner require professional installation?

A: This depends on your skills and circumstances. Should you be the type who generally fixes and optimizes everything on your RV, you’ll be fine. Replacing an existing rooftop unit is a straightforward installation and means just exchanging one box for another.

If you have installed an AC in your RV or home before, it’s likely not a challenge for you. If you can’t find any standard vents, don’t think your vehicle is yet equipped for any AC or are afraid of damaging the roof of your RV or trailer, consult a professional or trusted and skilled friend.

  1. As Gary pointed out noise levels need to be included in the comparison, and yes I know you did not have the equipment to measure them. Problem is noise levels are the #2 complaint below cooling output.

    We have the Airxcel Mach 15 unit as a front AC and it pumps out the cold. On a 90 degree day it keeps the bedroom in the mid 60’s. Great selling point but it’s so loud it drowns out large V16 diesel engines nearby. We are so use it the noise it puts out we use it for white noise. TV in the bedroom is useless because it can’t overcome the sound of the Mach 15.
