Best Heating in Houston TX

Charged $200 for 20 minutes of work to clean flame sensor and then left. I wasn't home so my girlfriend tried to pay on the spot, but was told we would get billed instead. Very overpriced for simple cleaning and maintenance.

We called Abacus for a coil cleaning and were quoted $79. My husband made sure to verify that it was for a coil cleaning and was told that it was indeed. However, on the day of our appointment, Abacus called to tell us 1) that the representative would be late and 2) that we had been misquoted. The $79 fee was a diagnostic fee. What?! Then when the representative arrived and was told that we wanted a cleaning and not a diagnosis, he insisted that he could not even enter the home unless we agreed to pay the diagnostic fee. Obviously, we sent him away. Not a good way to do business.
