AC issues


Recommended Posts

There are 2 ac/heatpumps on the roof, a 15k at the rear and 13.5 at the front of the trailer. The rear seems to be working


outside ground temp in the shade is about 80f

temp of inside of duct 49-45f taken with laser gun

condensation on ceiling duct flange

roof unit air exhaust 110f

condensation running off roof. A little over a gallon in 18hrs.


Fwd 13.5

air temp 75 out of ceiling duct

temp of ceiling adjacent to grill 78

roof unit exhaust air temp 95

no condensation on inside ceiling duct flange.

no condensation running off roof.


They both used to start up in 3 stages, a few minutes when temps were set, then some part of them would start then a minute or more later the second part or stage would start up.


Rear 15k still goes thru time delay then a 2 stage start up.


Front 13.5 still has time delay then starts up but doesn't seem to cool.


The front one seems to blow the breaker the odd time for some time.


Any diagnosis or recommendations?
