When I got my coach it was cold out the first of January and I never tried the AC. Well when the weather improved that is when I found out it did not get cold. I think when they replaced the radiator it did not get serviced trying to save $$$$ before they sold it. So I took it into Mac's Radiator and they did everything up front on the left of the gen set. They worked on it for about 3hrs to clean the system then charge it and added die to the system to check for leaks.
I know zip about AC system, just needs to be cold when you turn it on.
