RV AC Unit: Keeping Your RV Cool and Comfortable

As an avid RV enthusiast, you know that your RV is your home away from home. It’s your sanctuary on the road, and you want to make sure that it’s comfortable and inviting. One of the most important components of your RV is the air conditioning unit. Without it, your RV can quickly become hot and stuffy, making it difficult to relax and enjoy your travels. In this article, we’ll take a closer look at RV AC units, how they work, and what you need to know to keep your RV cool and comfortable.

How Does an RV AC Unit Work?

Before we dive into the specifics of RV AC units, it’s important to understand how they work. An RV AC unit operates much like a traditional home air conditioning unit. It uses a compressor, condenser, and evaporator to cool the air inside your RV. The compressor compresses the refrigerant gas, which then flows through the condenser where it releases heat. The refrigerant then flows through the evaporator, where it absorbs heat from the air inside your RV. The cooled air is then blown back into your RV through the air ducts.

The Different Types of RV AC Units

There are two main types of RV AC units: rooftop units and portable units. Rooftop units are the most common type of RV AC unit and are installed on the roof of your RV. They are typically more powerful than portable units and can cool larger areas more efficiently. Portable units, on the other hand, are smaller and can be moved from room to room. They are ideal for smaller RVs or for those who don’t want to install a rooftop unit.

Choosing the Right Size RV AC Unit

When it comes to choosing the right size RV AC unit, there are a few things to consider. The size of your RV, the climate you’ll be traveling in, and your personal preferences all play a role in determining the size of the unit you need. As a general rule, you’ll want to choose an AC unit that can cool your RV by 20-25 degrees Fahrenheit. This means that if the temperature outside is 90 degrees Fahrenheit, your AC unit should be able to cool your RV to 65-70 degrees Fahrenheit.

Maintaining Your RV AC Unit

Like any other appliance, your RV AC unit requires regular maintenance to keep it running smoothly. Here are a few tips to help you maintain your RV AC unit:

1. Clean or replace the air filter regularly. A dirty air filter can reduce the efficiency of your AC unit and make it work harder than it needs to.

2. Keep the condenser clean. The condenser is located on the roof of your RV and can become clogged with dirt and debris. Use a soft brush or compressed air to clean it regularly.

3. Check the refrigerant levels. Low refrigerant levels can cause your AC unit to work harder than it needs to, reducing its efficiency and lifespan.

4. Inspect the ductwork for leaks. Leaks in the ductwork can reduce the efficiency of your AC unit and make it work harder than it needs to.


Your RV AC unit is an essential component of your RV, keeping you cool and comfortable on the road. By understanding how it works, choosing the right size unit, and maintaining it properly, you can ensure that your RV stays cool and comfortable no matter where your travels take you. Whether you’re exploring the great outdoors or enjoying a weekend getaway, your RV AC unit will keep you cool and comfortable all summer long.
