“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.”

“David was great! Professional and competent, did an incredibly careful job. While the main problem with our old AC turned out to be clogged plumbing lines, he did careful clean-up, added solutions to breakup clogs, installed safety device, etc. He left the AC area in attic shining! We signed up for Abacus club, and want him to come back to do heater and AC checks regularly, then install new AC when the present one gives out. Abacus has become our company after all the jobs that you've done at our house since Sept (also rupture sewage line under foundation, new water heater, broken hot water line in attic...). Everyone was VERY responsive as we reported new problems in the house, and received very fast service.

“Jay was my technician. He explained everything very well, wore the booties while in the house, was honest and straightforward in our dealings and even though the job was not easily diagnosed and easily fixed, he stuck with it while making 2 trips here on a Sunday afternoon. During football no less even though the Texan's game was not a good one to watch as they lost. Initially it appeared to be the capacitor and he showed me why that needed to be replaced. Everything appeared to be working well until I noticed a couple of hours after he left I was still having some problems. After calling your dispatch he showed back up within the hour and determined my thermostat was faulty. Abacus was good and Jay was very good. I would like to have him out again if I have more problems. ”
