AC Not Keeping Up

Moved from Forum Technical Support

Shade and 2nd AC most bang for buck.

Take the cover off on the inside and make sure that the outlet (cold) air) is not recycling with the intake (warm) air. Remember that the air being cooled comes from the inside of the RV not from the roof. In some cases the two plenums are next to each other and the metal can separate and cause internal leaks and recirculation. Use aluminum tape to repair.

Other generic tips are, find shade, and run the A/C hard at night when it's cooler out to "sub cool" the coach. This may allow it to keep up better in the daytime. But it'll get cold at night.

Cover windows on the outside of the RV. Park with bedroom facing south. Start air conditioner early in the day. Spray the roof and sides with water.

IMO most can't keep up with the hot weather, especially if you only have one AC unit. Most RV's are not insulated like a home is. Most have single pane windows. Most are not very efficient. Parking in the shade can help, window coverings can help also. We use reflective bubble wrap on our sun side windows, it seems to help with the heat. It definitely does on our windshield. JMO
