I had him install a C wire which he did quickly and installed a new thermostat. But he was able to remove years of ick and grin from the coils and get the system running like new again. And quickly!!! Will use him for regular HVAC work!!

Billy did an outstanding job replacing my old thermostat to nest. He was very responsive, punctual and quick. I even hired someone to replace my thermostat before him and that person was unsuccessful. Billy was able to do in 10-15 min without issue. He also gave me some general HVAC advice. We will be hiring him in the future for all HVAC related work!

Billy came out today and did an excellent job on replacing our existing Carrier AC thermostats with the new Ecobee smart system without any problems. Arrived on time, very professional and knowledgeable. He checked and made sure everything was running smoothly and explained everything thoroughly. I would highly recommend him to anyone for any future projects related to HVAC systems.

Thank you Billy for coming out so late and doing an excellent job of removing the blocks in my A/C drains. I appreciate the overall quality and thought you put into your work and your prices were very reasonable for a weekend late night
