My AC wasn’t working and the solution wasn’t immediately apparent, but Sean committed to solving the problem. He knew his stuff, pulled in others when he needed to, and explained things well.

As usual, Matt was prompt and professional. I have learned more about units and parts from him over the past two years than in my previous 35 years as a homeowner.
Another 5 star visit by Matt & McCullough!
Matt performed the first annual maintenance 🔧on my A/C unit today.
Like his initial visit, Matt was very professional with every aspect of his review and informed me of his findings. Unlike previous technicians and HVAC companies, Matt excels in communicating very technical issues into clear and concise language.
I remain extremely satisfied with Matt and the staff at McCullough.
With summer 🏜 around the corner, I literally (and figuratively) feel great about my 🌬unit !!
