I’ve search for previous posts on my particular problem but have not found what is causing the issue.

We bought our 2018 Freedom Elite 30FE almost 3 years ago. It has a Coleman Mach 3 13000 btu air conditioning unit.

At first the air conditioner cooled the RV to an acceptable level (mid 70’s) unless it was extremely hot. The air coming out of the vents read in the mid 50’s - low 60’s.

This year, it just has not performed as it has in the past.

I’ve cleaned the evaporator and condenser coils, played with repositioning the thermistor probe, did a mod to optimize air flow, and during the day, in shade, the best the AC can do is 80 degrees inside. Outside temps are in the low to mid 90’s. The RV will not get down to our set 78 degrees and shut off until well after dark.
The air temps coming out of the vents only gets down to the low 60’s, unlike the 50’s of past years.

I don’t know what has changed. I called a mobile RV mechanic and he said he could get to me to look at the unit by late August. However he did tell me that if the problem was being caused by low Freon, that the Coleman unit is not designed to add coolant.
Can anyone offer some insight or offer ideas I haven’t incorporated as to what is causing my problems.
