A few reviews for this pro…




When I had a problem they looked up my records and came prepared and reAdy to efficiently remedies the issue

They installed my system 6 years ago.

CATEGORY heating & air conditioning/hvac




I paid this company to come back in to perform an inspection and they found the real problem and replaced the part and installed a new gas line with an automatic shut off valve.  They also made sure that our unit was up to code.  I ended up paying $330 to get it fixed rather than taking another companies word for it and replacing the system. I would highly recommend ATC.  I called and thanked them...

The tech that came out to do the work was Rich Diederichs and he was wonderful.  I had them come out to perform an inspection on our unit because another company tried to tell us that we need a whole new unit.  They found the problem and fixed it with no problems.
