We had an issue with our AC on a Saturday morning, and Henry arrived 30 minutes after we called. He fixed the problem very quickly and we were back in business.

Alex gave us the most information and comparison of product choices of the three HVAC companies we received estimates from to replace our unit. The technicians were prompt and finished in less time than predicted. The follow up visit by Jimmy was as scheduled and his check revealed the WiFi thermostat needed to be replaced which he promptly scheduled for the following week. They took care of all the rebates and provided the information about the tax credit filing. Great business to deal with.

There are no words to express how great my experience was with each of the McCullough employees I worked with. All were professional, knowledgeable, caring, and HONEST. Even the ladies at the office went above and beyond my expectations by keeping me informed and registering my new unit for me. Great company to work with. Will recommend to anyone needing HVAC service. Make McCullough Heating & Air Conditioning your 1st choice!

This is the 2nd time we’ve had Henry come out to the house for service. He’s absolutely fantastic. He’s really nice, knowledgeable of his trade, and able to make innovate improvements on the fly. Highly recommend McCullough and Henry.
