We had a wonderful experience with our service. Sam, our representative, was extremely professional, gracious and thorough. He took the time to diagnose the issues with our system and explain the issue. Everything was resolved in a timely manner, which is critical during the summer! Highly recommend

We are very pleased with the service we received. Thomas Ischy made it out the same day and was able to fix the AC and showed exactly where and what he was replacing. I’m definitely going to use them again for my HVAC repairs.

Craig was very professional, courteous and knowledgeable. He was able to assess the situation and then explain and answer all our questions patiently. He went above and beyond in figuring out how to operate a very tricky and uncooperative ladder that leads to the attic. Because of this we decided to go forward with MCCullough.
A very positive experience for a stressful situation.
