"Jeff and his team did and excellent job with the installation of two Daikin HVAC units. I had many questions about the units and install and they were quick and thorough in responding. The price and warranty were competitive with high end brands. The crew was courteous and professional during the two day install. They were the only company that included replacement of the coolant lines, rather than just flushing the old ones. So far the Daikin variable speed AC units are exceptionally quiet and the house is very comfortable. Would recommend Ace Home Services and Unique Comfort without reservation."

"The workmanship was very professional and cleaned up afterwards. Wouldn't even know they were here. Billy did an excellent job with the removal and instillation of a new hot water heater. Brought the instillation up to code by adding a drip pan and expansion tank. I have them coming back to replace valves for washing machine and installing shutoff valves."

"I was in need of a new water heater. When I posted looking for an installer I was contacted very promptly. During the conversation we discussed type of heater I would need and was quoted a very reasonable price . My appointment was set up with my choice of day and time and installer arrived at expected time. All work was neatly done and old heater was removed. I would certainly recommend 1-800-Plumber+Air"

I've been an electrician for nearly 10 years and I'm an owner-operated company based out of Quakertown. There is no job too small for me. A handful of jobs I take care of are outlets, switches, lights, ceiling, bath, and attic fans, electric car chargers, underground electric for outbuildings, electrical panels, service upgrades, troubleshooting and more.
