I would highly recommend Mark Hack of Osprey Air Conditioning and Heating. I called for an estimate on a new heating system that I was told that I needed by another company. Mark told me that I did not need a new air conditioning unit because of rusted coils. He quoted me a price for a 16 seer unit that was $1300 lower than the other estimate for a 13 seer. I would trust this man for honesty and excellent knowledge of his products. I was told I needed a 4 ton air conditioner and Mark told me that 3 and a half was all that I needed. If you need a new air conditioner or repairs call Mark.
