Air Conditioner is not cooling the trailer

I believe that having a 15K unit would be more help than you think. I read a post from someone who just changed his 13.5k unit for a 15K unit and was very happy with the results. However, If he were in the hot humid south, or the scorching deserts of Arizona, he may not think so.

I believe the answer is to install an additional unit, perhaps a 9.2K unit in the bedroom.

Absolutely agree on upping to a 15k or add another unit-and I double checked my post to make sure I mentioned my location. 98 degrees with 98% humidity is the daily forecast here. No way a 13.5 will ever cool a 27 foot fifth wheel satisfactorily (we like mid to low 70s inside) in 103 degree weather. Especially if you try to cook anything inside on the range or oven.

My point earlier is I was told numerous times my 13.5k was enough unit and that I needed to cover all my windows, use reflectix in my skylight/vents, and run my fan constant on high during the day and be happy with 78-82 degrees in the coach during the day. Add 2 kids to the mix in and out and we were miserable. So against my dealers recommendation I ripped out the newer 13.5 and installed a 15k. Problem solved. No special procedures required, just close the shades on the sunny side and we stay as cool as we like. My 15k unit cools the equivalent of a 27 foot fifth wheel, and I have a 13.5 chilling a 14 foot garage with a dryer running half the day.

My fiver shipped from the factory with a single 13.5 unit-what were they thinking!
