Sean was great, came out on a Sunday. I’ve called McCullogh before and I will call them next time I have an HVAC issue.

My boyfriend and I recently had our AC replaced by McCullough and couldn’t say enough good things about our experience. The project manager Evan was amazing to deal with. We had several companies come out and he was by far and away the most knowledgeable and straightforward. The crew did a great job with the install and were professional and tidy. We would not hesitate to recommend McCullough to anyone getting a new AC system.

They were great, Makayla is excellent. Very professional and knowledgeable about the systems, and made helpful recommendations for lowering my utility bills on a go forward basis. I will definitely continue to use the company and would like her to be the point of contact for a winter check up.
