You may have checked this but in the spirit of "trying to help" I thought I'd mention it.

Usually there is a tag in the area of the heater/ac box that has the type of refrigerant and the amount.

Other than that maybe someone with your same coach will help out.

When my dash A/C needed recharging I put in whatever amount of R-134a refrigerant that brought the "charge" in the system to the proper operating pressure..... using a "hose kit" like this:

However, I don't know the specific amount of R-134a refrigerant required for my system, your system or any other system.
Sorry

You say "compressor" but I assume you mean the dash AC system. My HR Navigator took about 13 cans after a new compressor was installed. I evacuated the system with a vacuum pump and then charged it with a manifold gauge set. The system pressures vary with outside temps. Here is a chart for R134a.

If you are asking about a standard rooftop RV Air Conditioner, they do not have ports for recharging. With the cost of installing them and the cost of freon, you are ahead to replace the unit.

This is your best chart if you have no knowledge of refrigeration, can get close. Remember to purge the air out of the hoses you use, air in the system will mess it all up. I would suggest you find a friend or friend of a friend to help you out.

On my rig with OTR AC in bedroom, the fill was @ 5.0 pounds of 134A and 8 oz of PAG oil.

The sticker describing the pounds of 134A and the type and amount of PAG oil is on the surge tank in the engine compartment.


The manufacturer of the system is out of business.
