We just wanted to let you know how impressed we were with the Gleason & Elfering team. Obviously, a furnace is somewhat of a blind item to lay people. So, in a sense, we had to find not simply “something”, but “someone” to trust. We commend you, not only for taking the time to answer all those questions intelligently, but for being cheerful, neat and unfailingly polite to boot. We will not hesitate to recommend your company to our friends who have heating or air conditioning needs.
