Our previous air conditioner was only 4 years old, but I refused to contact the installer as he was so unpleasant when contacted about a previous problem(wiring caught fire because he had installed too light of wire and had installed the the handler upside down). Jeff at Honest Air was recommended and, even though the compressor that failed would have been covered under warranty, I told him that I would not deal with the unpleasant individual that had installed that unit, so I purchased a new system from Honest Air and I am completely satisfied. The installers(Mike and David) were pleasant, efficient, and my air is cooler than it has ever been. I fully recommend this company!
