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.

Worse than car saleman - $491 and half day wasted. Somehow they got 5 star and a ton reviews on BBB - I don't believe it.  I'm sure Yelp has the real customer rating.

CenterPoint already tested and located the gas leak inside the wall.  However, Abacus was all about selling and getting the most money out of me with little regard to fixing my gas leak.  After the round about up selling, I just asked their plumbing guy to leave.  I still don't know where the leak is and got hit almost $500 but I refuse to further business with these shady practices.
