Rear ac recharge

I havenít opened up the AC to the back of the bus, but it needs to be recharged. Just curious if anyone has ever done this before and is it as simple as going to oíReillyís and getting some refrigerant like a car

Yes and no. Basically the same system. If it is empty it will take a LOT of small cans to fill it.

Bring it to an automotive AC shop and let them do a diagnostic. These systems take a lot of refrigerant and if you have a leak you'll waste money and just get frustrated.

Unless the system pressure is in the right range the various pressure switches will prevent the system from coming on (assuming it's just low on refrigerant), frustrating your diagnostic efforts.

Shops can test the current system pressure and tell you if it's just low or near zero, and they will be able to do a visual inspection of the hoses-they know what to look for.

Others more knowledgeable than me can give better details.

Last shorty I worked on with a separate rear unit had a capacity that was close to 15 lbs. You could have a case of cans and you still wouldn't have enough.

I echo the others, in that you should take it somewhere to be recovered, repaired, evacuated and then refilled. That much refrigerant isn't cheap, and I wouldn't recommend charging based off pressure on an automotive ac system, especially when so many of you don't have a gauge set, only a low side tap with a gauge in the handle.
