"Replaced 38 year old gas furnace, duct work and installed new smart thermostat. Anthony was very helpful and explained everything clearly. The 3 technicians did the work in 8 hours and cleaned up everything carefully. Anthony also cleaned my insert fireplace pilot light and helped me start the pilot light as a bonus! Highly recommend Perfect Star."

"Excellent. The Driver, Roberto was very punctual. Whenever he gave me a time of when he would be coming to either pickup the car or deliver the car, he was very punctual almost to the minute. Roberto did an excellent job. I couldn't be happier. I felt my "baby" was in good hands and he was very professional and responsible about the whole thing. I also liked that he gave me updates along the way."

"Matt and his crew did an excellent job with our new Carrier heat pump and Nest thermostat. All aspects of the project from the initial review, the quote, the installation and the followup were timely and professional. I would definitely work with Air Quality again. Five Stars."

"We had a wonderful experience with Got Watts. They installed 29 new solar panels for us and also upgraded our HVAC system (removed furnace/AC and installed new heat pump and air handler). We loved working with Eric, Jedd and Lee (HVAC), as well as Sam, Lindsay, Jeremy (solar). They were all responsive, professional, kind, knowledgeable, thorough. They even helped us through issues with PG&E and the rebate process. We highly recommend Got Watts."
