FYI I learned this week that roof air comes in two different BTUs 13500 or 15000.

I learned this as a result of being on the warm side at the beach last week with temps near 100 degrees and no shade. I had 2 of my , 13500 roof airs replaced yesterday with two 15000 BTU by Russell Coach in Knoxville. I called Rob from the beach and asked if he worked on them and he said no he just replaces them, when they start to fail it is time to replace.

So that is what we did and of course I am not at the beach but it was 92 degrees here yesterday and I had the temp in the coach at a cool 69 degrees.

Rob @ Russell Coach is a pleasure to do business with.
