CM Heating

Hired CM Heating for a routine furnace tune-up. The tech first told me my heat exchanger was cracked and there was rust. After I called their office, he changed it to: no crack, just a little rust — and the rust isn't a problem. But his meter was showing CO, he couldn't say why, and his answer was to replace the… Read full review

Edit: I fixed my problem myself for $60, they are liars that say a fix is impossible!!!

Update 12/8/2025 For some reason they thought I had a heat pump when I have a gas furnace and separate AC unit that they installed (both of them). So the servicing guy could only do the furnace and they'll need to come back in the spring for the AC. They had the same data issue earlier this year and I corrected… Read full review
