McCullough sent Sam our way to track down a problem causing our kwh usage to climb recently compared to same billing periods in past years. He was very persistent with his diagnostic procedures but got to the end of his day and will need to return tomorrow. The AC is cooling just fine so no inconvenience there. I am pleased that he is determined to find the issue and resolve it. It shows that he cares about his job and his customers. O

Our garbage disposal wasn’t working. I was so happy to learn that McCullough now offers plumbing services, and that free visits are included in my Comfort club membership! Will K came out and took care of everything and got our disposal working in no time. He gave me a courtesy call ahead of time, and was friendly and efficient. Think you, Will for helping us out today.

Highly recommend McCullough Heating and Air. On one occasion, our AC went out shortly before weekend guests were to arrive. Kyle and his team showed up after hours and quickly fixed the problem. We are incredibly grateful for their responsiveness and willingness to go the extra mile. Thank you Kyle and McCullough team - true professionals.
