MKirklandExplorerSep 09, 2014AC maintenanceMy question got lost in the Dog/AC posts. I simply would like to know what you do from year to year for AC maintenance. Does the freon have to be refilled every year, if you can? Thanks
beemerphile1ExplorerSep 09, 2014The typical RV A/C unit is sealed and you cannot add refrigerant without adding a port to the system. Normally refrigerant is never added.Clean the fins, filter, and drain holes. I clean the filter once or twice a year and the rest whenever I think of it. Probably two to three years.
