Your RV provides you with many of the creature comforts of home, but your RV’s A/C might not be as strong as you’d like on the hottest days of summer. There are a few factors that will impact how well your A/C will work: the climate of your destination, the size of your RV, and the number of A/C units you have.

As an example, if you only have one A/C unit on a large Class A and you’re expecting it to keep your interior cool in Florida during August, you’re probably going to be disappointed. But if you’re camping in Michigan with a smaller Class B, one A/C unit is probably enough to keep your interior cool.

Tips for Using Your RV A/C

You should outfit your rig’s A/C system to fit your camping lifestyle. RV A/C units are either ducted or non-ducted and come in a variety of weights and cooling capabilities. If you’re looking for a rig with a built-in unit, or if you’re upgrading or purchasing a new A/C unit, keep the following in mind: 

  • If your RV runs on 30 amps, then you will only be able to run one A/C unit. If you think you’ll want more than one cooling unit, you’ll need a rig that runs on 50 amps. Not all 50 amp RVs are prewired or ducted for a 2nd AC, so it’s good to ask in advance when shopping.
  • A unit with a higher BTU (British Thermal Units) has more cooling power and typically ranges from 11,000 to 15,00 BTU/hour. Many RVs come standard with units around 13,000 BTU/hour. A more powerful A/C unit isn’t always your answer to cooling your rig as it depends on the size of your rig and the climate you’re in. 

If using a portable A/C unit, keep an eye on your electricity usage and note any additions to your RV’s dimensions and weight.

Tips for Keeping Your RV Cool in the Summer

  • Park in shaded areas. 
  • Use your RV awning and window shades to reduce sun exposure when parked. 
  • Clean your A/C filters regularly. 
  • Cover your A/C in the off season or during long periods of storage to protect your A/C unit from critters and prevent the cooling fins from any storm damage.
  • Check your A/C for any unwanted intruders or damage (small animals can chew on the wires).
  • Check the temperature of your A/C for proper operation.
  • If you have non-ducted A/C, close off smaller areas of your rig to cool off your main living area more quickly. 
  • If you have ducted A/C, some models offer a replacement ceiling assembly to add a direct vent feature so you can perform the above step. 
  • Vent insulators will help trap cool air in your RV and make it more energy-efficient. 
  • Solar shields for your windshield, skylights, and windows will reflect UV rays and help regulate your rig’s interior temperature. 
  • Slide-out toppers also help protect your RV from the sun’s rays and keep the inside cool. 
  • Foil insulation works well for hybrids and pop-up campers. 
  • SoftStartRV is an easy-to-install device that allows you to run your A/C with more appliances by reducing the startup amps by 65 to 70 percent. It also reduces noise so you can sleep more comfortably with your A/C unit on.
How can I keep my RV cool without A/C?

Park your RV in shaded areas and use your RV awning when parked. Items like vent insulators, solar shields, and slide-out toppers (if you have slide-outs) can also help.

How do I keep my campervan cool in the summer?

Make sure you have an A/C unit that can handle the temperature and environment where you will be traveling and camping. Regularly clean your A/C filters and make sure you maintain your unit(s) throughout the year. 

How do you insulate an RV in the summer?
