An RV air conditioner that is operating properly has a 16 to 22 degree difference in temperature between the air immediately entering the return air grill and the air immediately leaving the supply air louvers. There is a simple test you can perform that will let you know if your RV air conditioner is operating properly prior to leaving on a hot weather RV trip. Watch the RV DIY video below to learn how easy it is to test your RV air conditioner’s cooling performance.
