The plastic housing for the double evaporator unit in the back of my bus is in bad shape. It is broken up, cracked, and shattered. The brand is Carrier. What are the chances I could get a new one? Or a nice used one? And where to look?
Also, I am looking to take my units down from the ceiling mounts so that I can spray some insulating foam. What should I do with the refrigerant lines ? I’m pretty sure the refrigerant R-134. Should I just discharge it into the atmosphere and put some stoppers in the lines?
