There’s nothing quite like taking your RV out for a long road trip, especially in the spring and summer. Beautiful weather, incredible destinations and lifelong memories are just a few things that make these vacations great.

The RV lifestyle is all about comfort, and the one thing that ensures comfort on a hot day is your AC unit. Those units work hard during the hot spring and summer months, so it’s important to clean and maintain your roof AC unit. Here are just a few reasons why you should perform regular maintenance on your AC unit, and tips on how to clean it:

Comfort Level

A rooftop AC unit’s main function is to keep you and your family comfortable during those hot days out on the road. Whether you’re driving through the Florida Panhandle or the Arizona desert, your AC unit is key to having a great trip.


Rooftop AC units put in a ton of work during the spring and summer, and that effort can have its costs. Replacing a rooftop AC unit is a time-consuming and expensive process that can keep you away from the road for a long period of time. Cleaning and performing regular maintenance on your AC unit, including the filters and coils, not only increases the longevity of your AC unit but also gets you out on the road visiting incredible places.


Most warranty companies prefer owners perform, at a minimum, annual maintenance on their rooftop AC units. Doing so will allow you to catch problems early and ensure that your warranty keeps you covered.

Cleaning and Maintenance Tips

Here are a few tips for performing annual maintenance on your rooftop AC unit from our experts here at Lazydays RV:

  • ? First, check the AC filters inside your RV. For any dirty filters you find, clean them by either blowing on them or washing and drying them in the sink.
  • ? When performing rooftop AC maintenance, make safety your priority. Have proper footwear and clothing on in case the roof is wet or slippery, and make sure the RV and AC unit is completely powered off before removing the covering.
  • ? Check to see if your copper lines are not rubbing against anything inside the unit. If you can’t adjust them, buy some rubber covers for padding.
  • ? Make sure your rooftop AC coils are clean and relatively straight.
