Best RV Air Conditioner Buying Guide

To choose the best unit for your recreational vehicle, you’ll need to consider several factors, including but not limited to size, power rating, and style.

This guide discusses these considerations in detail. Let’s begin with why you need an air conditioner inside your RV;

Advantages of RV AC Unit

All recreational vehicles come equipped with an inbuilt air conditioning system. So, the only reason you should invest in a separate air conditioning unit for the RV is to supplement your vehicle’s air conditioner system.

This is especially true if you’re camping in the summer. An RV can become pretty hot on a summer night. Air conditioning may be useful in such conditions to help you sleep better.

Unfortunately, most in-built RV air conditioning systems aren’t powerful enough to bring down the temperatures to the desired level.

Why? Because they mostly use battery power! Under such circumstances, an electric-powered RV AC can be brought in to boost indoor air conditions.

Thus they are energy efficient. Remember also that some RV AC units double up as heaters because they have a heat pump.

When buying an air conditioner for your RV, you can use the opportunity to invest in this type of AC, so you’re covered even during the colder months.

Best RV Air Conditioner Types

There are four main air conditioners for RVs, including rooftop, vent-free, portable, and window. Here’s what you need to know about each type;

Rooftop RV Air Conditioners

As the name suggests, rooftop RV ac are tucked into the roof. They are preferred over other RV air conditioners because they don’t take up space inside the RV.

There are options from 5,000BTU to 15,000 BTU cooling capacity when it comes to power– the choice is yours. A ducted rooftop is one of the best RV air conditioners because it guarantees 30% energy efficiency.

The RV air conditioners are cooled by the air outside, meaning that the weather outside the RV directly affects their operation. Rooftop RV air conditioners aren’t easy to install.

First off, the RV air conditioners weigh up to 100 pounds or more. So, you’ll have to plan for moving them around.

Secondly, installing rooftop RV air conditioners involves connecting a lot of wires and vents (for ducted types). Finally, the installation process requires at least two people working together.

Keep in mind that, since heat rises, rooftop RV air conditioners also can’t be used for heating. Another drawback is that the RV air conditioners add to the height of your vehicle.

Therefore, if you choose to buy one, find a sleep, low-profile model that doesn’t add too much height to your motorhome.

Vent-free Portable best RV Air Conditioners

Also known as swamp coolers because of how they handle moist air ventilation, vent-free portable RV air conditioners are smaller than other options on this list and typically come in attractive designs.

The main difference from vented options is that no refrigeration process is required to cool the air. Instead, air passing through the air conditioner is evaporated, and the resulting dry air is released to cool your indoors.

The lack of refrigeration makes vent-free RV air conditioners impressively energy efficient. However, these types of best RV AC units also come with a few downsides.

For one, they take up space on the floor, which might be inconvenient if you need to put other appliances or use them for other things.

Additionally, vent-free RV air conditioners work best in climates with dry heat. In relatively humid conditions, the RV air conditioner won’t be very effective at its job.

Portable RV Air Conditioner

All RV air conditioners are relatively small in size. But, portable ac units are the smallest in the category and feature handles for carrying the units around.

Since they are designed to be placed inside the RV, they are also generally beautiful in the vicinity of your guests and come in all kinds of shapes and colors.

The RV air conditioners feature one or two hoses for ventilation, with some equipped with adjustable frames for the window.

This way, you can position the air conditioner on the window from time to time. If you choose to buy a single-hose portable RV air conditioner, beware that they can be a bit inconvenient at dealing with heat.

The heat removed from the air can sometimes find its way back inside your RV. For this reason, two-hose models are better. That said, portable small RV AC units are the cheapest of the lot.

Single-hose models are particularly very cheap.

Window RV Air Conditioners

Finally, you can also choose a window air conditioner for your RV. As the name suggests, window RV AC units are designed to sit on the RV window. In fact, most of them are similar to window RV air conditioners used at home.

The RV air conditioners offer high cooling capacity – without taking up space on the RV floor. This makes them an attractive option for regular RV campers.

They come in small sizes, some as narrow as 14 inches. They are also quiet and easy to install than both vent-free and portable options.

Things To Consider When Purchasing An Air Conditioner For Your RV

Small portable air conditioner for camper There are several things to consider when buying an air conditioner for your RV. The following should be top of your list;

1. Power/BTUs

BTUs tell you how well an RV air conditioner can cool your space. To keep the heat out of your entire RV, you should be looking for at least 13,500 BTU cooling capacity for a medium-sized vehicle.

That’s because the RV isn’t a single room. Instead, there are several spaces to be cooled.

Additionally, the metal construction of recreational vehicles means that there’s bound to be substantial heat entering your vehicle. Only a powerful enough air conditioner can deal with such high amounts of heat.

2. Ducted vs. Non-Ducted

We mentioned this earlier when discussing types of RV air conditioners. For example, a ducted air conditioner blows air from within.

It has ductwork just like home air conditioning systems, and it is through these ducts, the air is blown into the RV. Non-ducted RV air conditioners don’t have ductwork.

Instead, they rely on the RV’s ductwork to distribute air throughout the vehicle. Each option has advantages and disadvantages.

For example, there’s the risk of hot air mixing with cool air in the “gap” between the zones for ducted options. Non-ducted options, meanwhile, are difficult to install.

3. Size and Shape

Whether you’re buying a rooftop or window model, size and shape are very important. The size of the air conditioner determines how much space it takes on the floor of the RV and, for rooftop models, how much clearance you have.

As for shape, we recommend a well-contoured, low-profile aerodynamic model with a shape that can resist drag.

Aerodynamic RV air conditioners not only keep your vehicle from being slowed down but also increases fuel efficiency.

4. Ease of Installation and Maintenance

Some RV air conditioning units are easy to install. Heck, some of the best portable ac models don’t even require installation. Unfortunately, however, some are also very difficult to install.

If you’re happy with calling a professional to do the installation and maintenance, you don’t have to worry about this point.

However, if you plan to install and maintain yourself, finding a less complicated model and readily available spare parts is advisable.

5. Extras

Some of the additional features you can look for in an RV air conditioner include; heat pump, air purifiers, remote control, and all-in-one functionality.

The number of air outlets is another factor you may want to keep in mind. Also, some RV air conditioners use batteries, while others don’t.

So if you’d like to use your air conditioner while driving, a model that can handle the 12V vehicle battery would be ideal.


Before buying any large appliance, it’s always important to do some research beforehand, particularly the features and specifications you should look out for in your chosen product.

With regard to small RV air conditioners, there are a variety of specifications that may be a priority for you: size, shape, weight, BTU rating, and ease of installation.

These are just considerations to factor in before making a final decision. You might also want a unit with lots of bonus features like timers, modes, and settings.

It’s entirely up to you. Now that you’ve considered some of the best small RV AC units on the market, you’ll be much better equipped when the time comes to making your purchase.

Now all that’s left is to get out and explore the world in your RV!
