Delta Air Systems

We had an air conditioner installed in our 1950's bungalow, which had never had a/c before. The quote was straightforward and the end price was exactly what was quoted. The two technicians were extremely polite and professional. Delta obviously puts a lot of emphasis on the conduct of their employees. The junior technician dropped something and let a swear word pop out. When they realized my wife was in earshot they both apologized profusely. Later on, they came and found me and apologized profusely yet again! Really not a big deal, but they obviously thought it was, and I appreciated that. I've used Delta a couple of other times (furnace servicing, etc) and have always been very pleased with the way I'm treated by the technicians. I've had nothing but good experiences with this company.
