Have a 30' Komfort trailer with roof AC unit. Blows air but doesn't get cold. Can these units be recharged? I couldn't find any hook-up points to add AC.
who told you that I think they were blowing smoke! they are a sealed system but they can be worked on.The new law says that it cant be charged if it does not have the fittings on it from the factory ( they dont) . They say you have to buy a new one. I am in the same boat but coolant might not be your problem. Say thanks to the global warming scam for the law.
