When one of my two heat pumps died three years ago a co-worker who moonlights as an energy auditor recommended getting at least four different estimates. That turned out to be excellent advice, since the quotes and the impressions I got from the six companies I had give me estimates were all over the map. When Karl from Air Conditioning Servicers came to my house he spent longer than the people from the other companies did inspecting my house and existing system. He pointed out a bunch of things about system that failed that likely lead to its early demist and he seemed like a real straight shooter. When his quote came in it was the second lowest and included a higher SEER heat pump than the lowest estimate did, so I went with his company and it is working way better than the old system did. Since then he has performed my annual services for me, and last week I had him replace my other heat pump, which was very unreliable, and replace some ductwork. The work on the second heat pump was completed less than a week after I requested an estimate, and I was impressed that he went beyond the letter of the contract to fix a couple unforeseen problems that appeared during the installation without charging me extra. While I highly recommend obtaining multiple estimates before having any major work done, I have been very happy with Air Conditioning Servicers, and I think they do excellent work at a reasonable price.
