"Trinity Heating installed a new thermostat in my house. The technician, Jimmy, was professional and courteous. After the installation he took the time to explain to me how to set up and use the new thermostat. I’m completely satisfied with their service and will use them again if needed."

"Ray is very professional, and provided options for my air conditioning unit replacement. Ray went out of his way to replace a small gas line leak that he found. He also drove to Anaheim early on Saturday morning to pick up a part that was needed for the AC unit, and came over to install it so that I would have the air conditioner available for the upcoming heat wave this week. He and his team were on time, and considerate during the installation process. I highly recommend RS Air Conditioning & Heating."
