Gabriella Hernandez
My A/C unit began having issues the day before the Fourth of July weekend. I called about 10 places and finally was recommended to McCullough by another local tech. Scheduling was simple and automated. My tech, Micheal, was amazing! My unit gave out completely and Micheal called me in the afternoon to let me know his ETA. He arrived earlier than expected and went right to work. The issue was resolved both quickly and efficiently. He even took the time to explain the condo’s HVAC system and answered all my questions. At 5p on a Friday during a holiday weekend, I couldn’t have asked for better service. I’m extremely pleased and highly recommend this company.

Jamie was a great plumber to help with a suddenly leaking hot water heater that needed to be replaced. Super professional, talked through and priced different options, and got the replacement done the same day. Will absolutely use him again.

Very pleased with everyone we interacted with at McCullough - from scheduling people to estimator, to installers to QA inspection. Very professional and courteous. We replaced an aged AC/furnace, ductwork, insulation and weatherization of doors, etc. We took quotes from two others and no regrets going with McCullough. Chris did an excellent job explaining options and recommendations - never felt like I was being sold.
