How to Choose the Right RV Air Conditioner

As perceived by humans, a comfortable temperature range is up to 79 degrees Fahrenheit in low humidity, and only up to 68 degrees Fahrenheit in high humidity. With average humidity, we feel most comfortable at temperatures between 64.5- and 71.5-degrees Fahrenheit. The fickle nature of human comfort makes the air conditioner one of the most important inventions of modern times.

Best RV Thermostat Banner

In 1929, Frigidaire introduced a split-system room cooler that was heavy, but small and shaped like a radio cabinet, the first in-home air conditioners. General Electric improved on this design and proceeded to develop thirty-two home air conditioner models in the early 1930s, eight around the time the first RVs were made available to consumers. With the rise in popularity of recreational vehicles as traveling vacation homes, RV air conditioners became commonplace.

Is your RV air conditioner start slow? Is the air current weak or warm? Is it leaking, or does it only work well on specific speed settings? Has it gotten loud? You may need to replace your old unit. Knowing your air conditioner model is an essential first step if you are looking for a replacement.

You should only need to remove your ceiling assembly and perhaps use a flashlight to find the manufacturer’s data tag. RV air conditioners are available for ducted and non-ducted RV campers, so knowing which you have is also important.

Typically, there is a 14″ x 14″ space in the top of your coach made for an RV air conditioner. The installation will require you to unscrew your ceiling from the inside using the four mounting bolts. Remember to disconnect from your power supply before you remove an old air conditioning unit and/or install a new one.

With the top unit off the outside, proper installation will require you to align your RV air conditioning unit with the cut out using the preinstalled gasket. If your RV is ducted, you will have to line up your face place with your ductwork and connect your thermostat to your control kit.

Whether you are replacing an old-fashioned one, or whether you are looking to purchase your first RV air conditioning unit, there are several factors to consider as you’re shopping around, including BTUs, shape, and installation simplicity. You will also want a reasonably quiet one so that it doesn’t distract you when you are driving or disturb you while you are trying to sleep.

Key Features to Look For


BTUs (British Thermal Units) describes the amount of heat energy required to increase the temperature of a pound of water by one degree Fahrenheit. One thousand fifty-five joules are the approximate equivalent of one BTU. BTUs will determine how effectively your RV air conditioning unit will be able to chill your space to a comfortable temperature.

Power is a crucial consideration when it comes to RV air conditioners. 13,500 BTU is typical, and higher output will give a little better performance in extreme heat. On the other hand, if you won’t be using your unit often, nor in extreme conditions, you might reasonably be tempted by the lower prices of lower BTU appliances.

Some people prefer to install more than one unit, as a large RV may take up to 18,000 BTUs to cool satisfactorily.

Installation Simplicity

To some extent, this is about the weight of the unit. Especially if you plan to install the air conditioner yourself, you will do better with something compact and not too heavy, and that comes with well written, easy to interpret installation direction and a comprehensive unit manual.


If you are already experienced with RV air conditioners and have had a positive experience in the past, brand loyalty may factor in your shopping. Something else to consider is simply that if you already have replacement parts on hand, you may want to shop with brand compatibility in mind for that reason.

Shape & Size

Compact and aerodynamic are both features that make sense in an item that is going to be mounted on the roof of your moving vehicle. You want an RV air conditioner that will resist wind drag and allow your recreational vehicle as fast, stable, and fuel-efficient as possible. You will also want to factor your RV air conditioner into your vehicle’s overall clearance.

As mentioned above, the hole size for RV air conditioners is pretty standard. However, height can vary significantly. Keeping to a lower profile is often a trade-off between power and drag. That said, the more compact AC units with lower BTUs are also usually more affordable. Hence, it’s wise to think through your energy needs so that you are only compromising your aerodynamics and investing in maximum BTUs out of necessity.

Types of RV Air Conditioner Units

No matter the model, size, and age of your unit, chances are your RV came with a preinstalled rooftop air conditioning unit. The advantages of this installation placement include that it does not black windows or take up already limited floor space. This type of RV air conditioner is reliable and notably energy efficient at cooling a functional size space quickly.

The largest RVs, for instance, a 45-foot Class A diesel pusher, might benefit from a second air conditioner unit for the back bedroom, where you can close a door between that space and the main living area. A portable, ventless, indoor RV air conditioner. These are small, but they do take up floor space. On the upside, they often also include dehumidifier features, they require no mechanical skills to set up, and they are relatively affordable.

Window RV AC units (or floor units that use a window vent) are a less popular option. They are unsightly, and if they aren’t installed correctly can create dangerous fumes.


A loud fan or a noisy RV air conditioner fan motor can disrupt your sleep and make you an unpleasant campground neighbor. Starting with a quality appliance is the first tier toward preventing this problem. Secondarily, strange noises can crop up concerning basic mechanical malfunctions, for instance, something coming loose. Check your screen and vent before you assume it’s anything more technical than that.

Dual Use

When shopping for an RV air conditioner, you may notice that there are dual-usage units on the market. The increased versatility of these units is the advantage of an alternative heater, which means that you have less need to burn propane for heat (and therefore can buy propane less often).

Dual-usage RV air conditioners include a heat pump, allowing them to function not only as air conditioners but as heat sources, too. As one might expect, RV air conditioners with this heat pump feature are generally more expensive, and a heat pump is not designed to heat your RV to toasty comfort in the freezing cold.


RV air conditioners are great and present your key to comfort on the road and at your campsite. Like any other piece of equipment, however, RV air conditioning units do need regular maintenance, and eventually, they will wear and break. An RV air conditioner cover can also be a good investment in protecting your RV AC unit, though nothing lasts forever.

With this in mind, be sure to check your camper air conditioner for simple problems and have the number of a mechanic that you trust on hand for when things get more complicated. If you are reading here because the worst has happened, and it is now necessary to completely replace your RV air conditioner, hopefully, this post will help you feel adequately armed with the knowledge you’ll need to make an excellent selection for your RV.
