"Honest, reasonable, timely & has done work for my family for 15 years. New HVAC unit recently completed. What can I say about Full Efficiency and Carlos? I have been using them for a decade and my entire family for longer. Carlos always puts the customer first, whatever it takes. As an example my HVAC unit had begun to drip & rust. Most companies would just call it normal conditions, and run. Not Carlos. He called the manufacturer and went to bat for me. A few weeks later I learned that Full Efficiency was able to convince the manufacturer to replace my unit at minimal cost. There are few if any companies that would have taken the time or even cared. Most in fact, would try to sell you a new unit. Again that's not the way Carlos works if you need a new HVAC unit he'll tell you. If all it needs is a repair, he'll tell you that too."

"Phil serviced our AC today and he was wonderful. He communicated exactly what what wrong with the unit as well as ways to fix the issue in an affordable manner. He took care of the unit quickly and also installed our new thermostat, without adding the cost to his estimate. I would definitely recommend Phil/One Hour to everyone as everything is working like a charm!"

He takes the time to explain everything, does quality work, and always cleans up after himself. It’s hard to find someone this trustworthy these days, and I’ll definitely be using Rich for all my HVAC needs."
