Best AC Units for RV Life: Keeping Cool on the Road

When you want to enjoy your adventures on the road, nobody wants their RV domain to feel uncomfortable and sticky. Whether it be at the beach, in the desert, or at a campsite—your recreational vehicle is your go-to for comfort and rest. 

The easiest way to achieve maximum temperature comfort in your recreational vehicle is by investing in an air conditioning unit. If you’ve found your way here, you are likely sussing out the best RV air conditioner for your needs. Whether you are looking to install one for the first time or to replace an old one, read on to learn all you need to know about RV air conditioners.

How to Choose the Right RV Air Conditioner

The maximum comfortable temperature for humans 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.

Typically, there is a 14″ x 14″ space in the top of your coach made for an RV AC unit. The installation will require you to unscrew your ceiling from inside the RV 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 AC unit with the cut-out using the preinstalled gasket. If your RV is ducted, you will have to line up your faceplate with your ductwork and connect your thermostat to your control panel.

There are many reasons you may want to replace your current AC unit with a new RV air conditioner. Is the old one slow to start? Is the airflow current weak or warm? Is it leaking, or does it only work well on specific speed settings? Has it gotten noisy? If you are looking for a replacement unit then knowing the model of the air conditioner you currently have is an essential first step

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

Whether you are replacing an old-fashioned unit or looking to buy an RV air conditioner for the first time, there are several factors to consider as you’re shopping around. These include the unit’s BTUs, its shape, noise level, and simplicity of installation.

Key Features to Look For


BTUs (British Thermal Units) describe the amount of heat energy required to increase the temperature of a pound of water by one degree Fahrenheit. BTUs will determine how effectively your AC unit will be able to chill your space to a comfortable temperature.

The BTU rating is a crucial consideration when it comes to choosing an RV AC unit. 13,500 BTU is typical, with a higher output giving 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 may prefer to install more than one unit, as large RVs may take up to 18,000 BTUs to cool satisfactorily.

Ease of Installation 

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


For RV owners with previous experience with air conditioner units, brand loyalty may factor in your shopping. Something else to consider is 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 important features for an item that is going to be mounted onto the roof of your moving vehicle. You want an RV AC unit that will resist wind drag and allow your recreational vehicle to be as fast, stable, and fuel-efficient as possible. You will also want to factor the height of your air conditioner into your vehicle’s overall clearance.

As mentioned above, the size of space in your RV ceiling for a rooftop AC unit is pretty standard. However, height can vary significantly. There is often a trade-off between increased power and a lower profile producing less drag. 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 the 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 conditioner. The advantages of an installed placement are that it does not block windows or take up already limited floor space. This type of air conditioner is reliable and notably energy efficient at cooling a functional size space quickly.

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.

There is also the option of buying portable, ventless, indoor RV air conditioners. These are small but do take up floor space. On the upside, they often also include dehumidifier features, require no mechanical skills to set up, and are relatively affordable. This may be an option for larger 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 loud AC unit fan, or a noisy fan motor, can disrupt your sleep and make you an unpopular campground neighbor. Buying a quality appliance should avoid this problem when it is functioning properly. But if it is making strange noises it could be due to some 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 dual-usage units on the market. A dual-usage RV AC unit will include a heat pump, allowing them to function not only as air conditioners but as heat sources as well. 

As one might expect, 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 freezing cold weather.

However, the increased versatility of these units is advantageous over using a separate heater, as you will have less need to burn propane for heat (and therefore can buy propane less often).


RV AC units are great, and essential in some cases, to have affording you comfort on the road and at your campsite. Like any other piece of equipment, AC for RV use will require regular maintenance, and eventually, they will wear and break. Air conditioner cover can 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.

Now you know what to look for in an A/C unit let’s take a look at the best RV air conditioners on the market today.
