Best Home Building in Charlotte NC

After calling Accent Comfort Services to check my AC not functioning properly, I was given the diagnosis that the TXV needed to be changed (quoted an estimate of over $700 to get it repaired).  I called another company which checked the TXV and concluded there was nothing wrong with the TXV.  The problem was the damper was in the closed position and the thermostat was bad.  After repairing those problems diagnosed by the new company, my AC worked properly as it should.  Not only was I given the wrong diagnosis by Accent Comfort Services, but refused to refund me the misdiagnosis claiming they can't do anything due to some time passed by even though I have proof of everything that was done and they can check for themselves. Moreover, I had called them more than once to be emailed a receipt of the charges for them coming over and giving me their diagnosis (since I was calling from out of state)...needless to say, I still haven't received any.  Takes a bad experience to learn.
