Our service tech, Mike Mctaggart, did a great job for us. He’s very professional, knowledgeable, efficient, friendly, and thorough. We plan to request him as our tech next time we need service.

Mike did an excellent job in assessing the situation with my A/C and providing explanations and options. He did not charge for his visit to give me a second opinion to compare with other companies. I highly recommend McCullough to anyone having an HVAC problem.

Mike was great! Moved around his schedule to get my AC fixed when it gave out on a 100 degree day. Quick service got everything working again. Definitely recommend.
