Air Conditioning in Houston on June 11th, 2014

“During the installation of my new AC/Furnace, I had the pleasure of working with HVAC Manager Chris Crawford and HVAC Techs Jason Bowman & Gary M., who all gave me "white-glove" service to the max! Working in the installation industry myself, I must say they were all about the customer experience. On the day of installation HVAC Tech Jason Bowman was there to see my job thru completion on his DAY OFF! Hats off to the team that worked my install!”

“We had an annual Checkup on A/C. As usual the technician was very well informed and helped us to make the right decisions so we can prolong the life of our AC unit as long as possible. He also took the time to walk me through some maintenance tips and show me what we can do to make sure we don't find ourselves in a negative situations. We have been using Abacus for over 7 years for plumbing and was so excited when they also offered AC services. The technicians are always very nice and take the time to explain everything to us.”
