Great experience! Our AC went out and McCullough was quick to come out and diagnose the issue. Narrowed it down and didn’t try to give me an inflated estimate and cost as other contractors did. The technician, Henry, was great to work with! Very clearly and thoroughly explained what the issue was and gave us a clear way ahead.
