So far the unit from Air Temp Mechanical Services has saved me quite a bit of money on my electricity bill, because I have an electric heater. I got a single unit, and I regret it. I should have gotten 2 units, but it seems to be working out pretty well. I read my electric bill, and I know it is saving me money, but I haven't gotten around to putting everything in a database yet to really look at it.

The installation was very neat. They did a very nice job. If I was rating the installation they would get a 5. I really do expect good service, so I am not surprised when I get it. If I don't get it I just don't go back to that company.
