Anyone have issues cooling a 24' TH with a 13500 btu?

My 13.5 unit is marginal at best as is the heater.
Cheap and easy trick to help both heater and A/C, a roll of wide masking tape to seal around the ramp door. Easier to remove than put on, but it does help.

My experience with RV A/C units is that when its really hot 90+º out. THe units will struggle when parked in direct sunlight with no shade. A little shade will go a long way. The units simply aren't able to overcome and keep up with the extreme heat generated by the direct sun light.

the new units have a diff Freon in them as apposed to the say '08 units and DO NOT cool as well as the older ones but I have a 2011 wp 295 with the 13500 unit and once it gets over 95 it runs non stop and doesn't do a great job but does still work. at first it didn't do well but I pulled the cover and could see daylight and the bottom side of the ac cover through the 5 spots they didn't get sealed up so the return air it was pulling in to cool was partially being drawn from the attic ( so to speak ) and the outside. got it sealed up and worked better.

How warm was the interior before you turned on the unit?

Are you sure it is on a/c and not just fan? Just saying!

Is it ducted throughout the TT?

Yes both compressor and fan were running. No ducts. The TH was very hot after pulling it. 100+ degree's or more inside when I pulled into my camp spot around noon with no shade. Then I left the AC running and came back after dark and it was still warm inside. It finally caught up in the morning.. Kind of. But I just figured, why have a AC unit which takes 12 hours to cool it down in worst case heat scenario's..

My bed location close to the ceiling doesn't help. The AC unit cools the entire area. No walls, and a huge door in the back. And like I mentioned.. Styrofoam 1" insulation loosely fit in the spaces of a aluminum trainer doesn't do much. I don't think the ceiling has any insulation. And Im sure the floor doesn't.

Does my AC have service ports? I didn't even look since I was getting a great 25 degree drop across the A coil when testing. Maybe I need to clean the condenser..

Mine works fine I believe it is a Colman Mach. It does a great job on low setting at 90-95 degrees last year.

Most AC's whether they are 13,500 or 15K BTU's will only pull the temp down about 20 degrees from the ambient/outside air temp. I would think that TH's would be harder to cool as they have such large rear storage areas.

I wish our 22' TT had ducted air as the single, centrally located 13,500 BTU unit is loud but it will bring the temp down very quickly. Can't imagine how all of the 30'+ TT's with 13,500 units manage to generate enough cool air particularly in area's with lots of high humidity to deal with. If your TT is going to be anything over 27' look for a 15K BTU minimum if there is much warm weather camping in your future. :C
