I am having trouble with my Proheat and read some past posts to try to get a handle on what was going on. I ran into Broompilot's post about a dealer outside of Houston that did him a good job. I would like to know who that dealer is so I can look them up. I also read some about upgrades that were covered under warrantee. Will look into this also. In the meantime, the heat won't heat and the AC compressor doesn't seem to be kicking in. Sitting in Raleigh, NC and this would be a good day to get things done if I can. Anybody know where to take it around here?
