Guillermo was extremely professional and effective. He was able to diagnose an issue with one room being hotter than the others when I have mentioned this problem for years to other technicians! I appreciate him!

Zach did an excellent and thorough job in my system check. He was prompt and polite. I always recommend McCullough to friends and family. Thank you.

Leaving 4 rather than 5 stars to encompass the entire process. The HVAC tech, Kyle did a stellar job. Efficient and knowledgeable. However the in-office customer service team needs some support, I found them to be disengaged and disorganized. After the diagnosis and paying half the bill, I had to reach out for an update 3 days later since I had not heard from them. Then when the service was scheduled for the repair, the gas valve was supposed to be delivered to my home address. Kyle shows up baffled the part was sent to their main store, needing another tech to drive it over. I even tried to confirm via text with the customer service rep, but they left me on read for that specific question. Needless to say, all is well and I have heat, but if you are paying a hefty price for services, they need to be organized. Shout out to Kyle.
