We have had another HVAC come out four times to “fix” our six year old unit. Derek came out promptly, completed his testing and diagnostics and located the concern. He was honest with his findings and informed us that it was a problem not involving the HVAC unit itself. He could had easily told us something else needed to be replaced in the unit and charged us for parts and labor, and we would have been none the wiser, but he was honest and told us that the issue was outside his scope and gave us his recommendation.
