Does anyone else have a complaint/issue with roof air not able to get temp below 80 degrees or so.
Especially when outside temps are mid-eighties or higher.
Air return filters are clean and even on high cool cannot seem to get cooler . I have even run both engine air and roof air and that will help a little.
You might want to take a look at the divider that separates input air from output air - mine was loose and leaning over, letting the cooled air coming out mix with the room air going in. Putting the divider where it was supposed to be and taping it in place made a huge difference in performance of the A/C. This is not a rare condition apparently - there are quite few videos on youtube shwing exactly this condition.
