To inspect the system for leaks, a A/C guy must use his special light to look for the fluorescing die that was put into your system.
He will have to look at entire system, every inch of pipe INCLUDING all of the parts inside the condenser ( the big box in your basement ) and the evaporator ( the part that gets cold ).
In order to look inside the evaporator and condenser they pretty much have to be removed from the coach and opened up.
If you go this far, make sure your A/C guy cleans the condenser and evaporator ( no matter how it looks ) and make sure the pipes inside the condenser are insulated very well.
I have all 4 of my CA's out of my bus right now. I am making some modifications to make my units work in HOT weather. ( the reason I have AC )
Good Luck
Rick
