I have an Airxcel model 46413-812, that's mounted under my park model, that's always seemed to take a long time to cool our 500 sq ft park model. It's a 13,500 BTU unit, so it's plenty big..The park model has skirting all the way around the unit and the skirting is vented with 3 - 2' x 3' screens to allow airflow under the unit.There is no debris in the coil and the inside air return is clean. The airflow out the 4 vents seems very weak to me. It's 7 years old. I don't believe there's a high or low speed fan connection by looking at the diagram. The other day it was 91 degrees here and the A/C unit ran for 5+ hours before it turned off at 77 degrees.
Thanks for any comments
I'm not sure I would call a 13,500 btu unit plenty big for a 500 sqft park unit.
at an average of 10' wide that means your dealing with a 50' long trailer.
If you look at most rv's anything over 35' long usually gets a second AC unit and always gets a 15,000 btu primary.
Remember most rv's have thin walls, and much less insulation than a sticks and bricks house, so the AC requirements will be higher than a comparable sized house.
