Of course we waited until it finally got cold to turn on the heater, and it would not turn on. I sent an email on Sunday via Angies List and was called back at 9:30 Monday morning. By 10:50 they were at my door! I was very pleased with this quick response - which was unexpected because I know they must have gotten tons of calls. The thermostat was a bit pricey, and $20 had to be added on because the footprint was smaller than my existing thermostat, and it would have needed touch-up paint. (and I didn't have any). So the thermostat price was $195. I thought that was a bit overpriced for a $50 thermostat, but it's done and I have heat and I'm happy. They had to mess with the heater to get it to work. Hard for me to understand exactly what they did, but they were here for an hour working on it, and then testing the system to make sure everything worked properly before they left. They also removed my filters so that I could replace them, which was a nice touch as they are in the ceiling - kind of a pain for me to get at them. There were two guys who came out, one was the owner, both nice guys and very polite. The total bill was $230 including the $20 AL member discount. UPDATE: Two weeks after they came in and "fixed" our heater, it stopped working again. I called them back and they came out and wanted $500 to replace the circuit board. I said I'd have to wait and discuss this with my husband. We were able to buy the circuit board online for $125 and it was easy to install ourselves. These guys are very nice and responsive, but I think their fees are too high. It took my husband, (who is handy but had never done this type of repair before) 20 minutes. I'm sure it would have taken the repair man less than that, and he probably was able to purchase the part at wholesale. So basically around $400+ an hour for repair?????
