Can you put Freon in an RV air conditioner?

The air conditioner works by passing air over an evaporator coil, which is cooled by the use of a refrigerant. The most common refrigerant is Freon, a brand name owned by DuPont that is universally–albeit mistakenly–used as a generic term. It is possible to put Freon into some RV rooftop air conditioners.

Unlike home split system air conditioners, RV units are not designed from the factory to be recharged. As a result you cannot check an RV unit using pressure gauges without installing valves. I am often asked by RVers to check the Freon® in their unit. In very rare instances some high end RV’s do have a split system.

Additionally, why is my AC running but not cooling? There are a couple of reasons for ice buildup in your AC — dirty coils or filters resulting in poor airflow, or a lack of refrigerant. If that doesn’t get the unit blowing cold air again, it could be refrigerant levels are low (see below).
