I had my HVAC blower go out and need a blower replacement. I searched and found McCullough as a preferred company through the carrier hvac site and got connected with Craig. Craig was very knowledgable and very helpful. He answered all my questions and in the end I ended up getting a maintenance plan with the company. Heat works great now! Thanks Craig

We have used McCullough's for years & always have a great customer experience! When we had our new outside unit installed in the Spring, Joey saved us by recommending that we do so...thank goodness with the Summer that came! We had our fall ac/heater checkup & our service tech, James P. was OUTSTANDING! He called me 30 minutes before, was on time, answered my questions, was very professional & personable. I highly recommend this company.
Brian came out today on2/24/26 to check on our ac. He was very through, checking everything out & removing the leaves from the outside unit. He told me about a treatment to spray into the vents that we may do.
Thank you!
