I needed an entire new heat pump system as the one I had was 28 years old and leaking badly. Bob was truly professional in all senses of the word. He provided a flowchart for the whole house and recommended an additional vent in one room, in short more homework than any of the other bidders as well as the best price! His guys even laid out drop cloths because of the mud from recent rains. Everything   was done in a professional and timely manner. My highest recommendation to anyone needing AC service.
