Finally an HVAC company that came up with an actual long term solution to what was causing continual issues with my air handler vs just putting an expensive bandaid on the issue just to come back every year. Dereck was on time, professional, efficient in his diagnosis and thought through a solution that no one else had suggested in 4 years of me owning the system. I will be switching my go to HVAC business to McCullough as I need long term solutions to address the core of the issue , not expensive temporary yearly services. Relieved I tried a new company this time around and called McCullough.

McCollough is the best and Chris is the best of the best! McCollough’s service plan and technicians are fabulous. Chris thoroughly evaluated my units, replaced the filters (one in an extremely difficult location), and then explained all the problems with one of the units and costed out the needed repairs. And he’s very pleasant. The best service I’ve had from McCollough yet. Thank you, McCollough and Chris!
