Call anyone but these people. They sent a kid to my home under the guise of a $65 diagnostic charge. After a while he said he needed to go back to the office for a fan for my HVAC unit, and he came back again. When the kid said I was at $600 "so far" I paid them $100 and refused more work. They left my unit dis-assembled. David Settle was twice rude and hostile. I gave these pirates $100 to vandalize my home, look elsewhere.
