I have used McCullough Heating and Air multiple times over the past year when my HVAC has given me issues. They are easy to communicate and flexible with their scheduling. All of the service providers have been very considerate and friendly when doing ...their repair work. They provide options for repair plans and offer helpful advice for the longevity of my HVAC. Jeff went above and beyond in getting my HVAC working today. I will continue to utilize McCullough Heating and Air for future HVAC needs.Read More...

I recently had a 3 ton Infinity System installed by McCullough. The team that did the install, Ian, Shawn, Glass and George did an outstanding job. No complaints. They were able to do a full install.......HVAC, thermostat, ducts, vents and ...insulation.....in a day. Again job well done. The Sales Rep, Troy Moomey, was knowledgeable and very easy to work with. I would not hesitate to recommend the team for any AC needs. Thank you.Read More...

Desmond was courteous, thorough and went above and beyond to diagnose my issue and get my system reset and back up and running after a power outage. I will definitely use McCullough again.

Was supposed to be just a second opinion but the technician found the issue really quickly and was able to pinpoint the cause of the issue. The other three previous quotes which claimed I would need a whole new ac system costing thousands of dollars ...meanwhile the technician here said it was no more than drains needing to be cleaned out costing a few hundred dollars and got my ac running correctly again. Really glad I had them take a look at my issue or I may be in financial debt now.Read More...
