We had an excellent experience with McCullough heating and air. Our 7 year old Carrier Infinity AC system broke down and it was still in warranty. Another company whom I had been using quoted - 6 to 8 weeks for repair and we started considering replacing the system.

I called McCullough for estimate for new system and their representative Kelvin suggested checking for repair first and setup us for repair service call.

Mathew came for repair, he checked what parts (compressor, inverter board) had to be replaced, got them from Carrier the same day and installed them and fixed the system in the same day (and much less than the cost that other service was quoting).

Thank you so much - Kelvin (for honest suggestion)
Thank you so much - Mathew (for fixing our AC in just one day)

Brandon came out to take a look at some issues we were having with our system. He quickly diagnosed the issue, fixed it, and made some great suggestions on how to keep our newer system running smoothly. He was on time, super friendly, and professional. Would gladly welcome Brandon back again to work on our unit any time.
