It’s summer, which means RVers everywhere are trying to tame the gods of heat and humidity with the divine invention of air conditioning. Here are a few tips to keep your towable RVs and motorhomes’ A/C system in shape through the sweltering summer months.

How an Air Conditioner Works: The Simple Explanation

An air conditioner essentially sucks air through its intake and extracts heat from it by running the air through an evaporator. The cold air that remains is distributed through the vents and cools the interior of your coach. The most important aspect of a well-running A/C system is airflow. Maintaining proper airflow in you RV’s air conditioning system is crucial to ensure that your unit runs as it should.


Keeping your interior filters clean is a great first step toward maintaining airflow. You can replace your filters when they get dirty, or you can clean your filters and save the expense of buying new ones.

To clean filters inside your luxury RV or motorhome, remove the filter, wash it with water, shake out the debris and reinstall it. A clean filter allows air to flow.

Roof Units

Your outside unit can accumulate dust, dirt and leaves that can inhibit airflow. It’s always a good idea to keep the unit clean so air can flow through it properly.

To clean your roof unit, you must first remove its housing. Then take a hose and wash the condensing unit by running water over the coils. The coils will dry naturally when you restart you’re A/C unit. There is no need to use a spray nozzle or attack the coils with any kind of pressurized water, since this can potentially collapse the fins and reduce airflow. If you happen to collapse your unit’s fins, you can buy a fin comb at most auto parts retailers and use the comb to brush the fins back to their proper place.
