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).

Can I use car refrigerant in my home AC?
You cannot use the same refrigerant, unless the system is specifically designed for that type. Here in the US, they use R134a for cars (older cars used R12). Central AC systems here use R22 and R410a (although R22 is becoming rare).
Can I run my RV AC on 110?
Ok lets say you have 30 amp trailer power you use the normal 30 to 110 adapter. Not using any other extension cords or stuff. Running the ac should be ok, however you will most likely not be able to run much else. Good power management is important when plugged into standard 110.
What is r22 refrigerant being replaced with?
Can I buy r22 freon?
However, servicing current, existing equipment is still acceptable if there is an available supply of R22. To confirm the public’s compliance with the new law, all sales of R22 must be purchased by a certified technician. Only recycled R22 refrigerant will be available to service existing air conditioners after 2020.
How do I change the Freon in my AC unit?
Before you add Freon to an AC unit, make sure to clean the air filter, blower wheel, and coils to ensure your unit is running smoothly. Then, put on some gloves and safety glasses to protect yourself from the Freon and turn off your AC. After it is off, hook up the refrigerant gauges to the valve connections.
Do RV air conditioners have filters?
Dirty AC filters can reduce the cooling capacity and efficiency of your Air Conditioner/s. The filters for RV Roof air conditioners are located inside the RV under the air distribution bezel on the AC unit. Once the filter/s is removed on most RV Air Conditioning units you will be able to see the evaporator coils.
