Highly recommend”
“My HVAC system was 30 years old. I noticed a strange smell during winter heating and more dust during summer cooling. My heating was cracked and my cooling had duct issues. The whole system needed replacing. Duncan was recommended by friends. They were easy to contact, easy to schedule, and the first quote was the one they charged. This is a family-owned and operated business and the pride they take in their work is exceptional. The total installation covered 3 days and communication was superb. They showed me the before and after units and their estimate was detailed. No surprises, no overcharging or corners cut. At the end of each day they cleaned up thoroughly. These are the guys to call, folks.”
