"David helped me install Heat Pump Water Heater that I purchased from Home Depot. It was his first time installing a heat pump water heater but he made sure it gets installed as per code and right way. He worked with me to install stop valve in the end."

"My grandson flushed his little yellow bus down the toilet Friday afternoon. I called several plumbers in the area. By late Saturday afternoon I had only 1 returned call saying they could come out Monday morning. A friend suggested I call Gentille Plumbing and Heating. I called them and they said they could come early Sunday morning. Ryan arrived promptly as promise and quickly determine how to approach the issue and retrieved the little yellow bus. Cleanup was quick and pricing fair. Ryan was professional , friendly and was on his way within 45 minutes of arrival. Thank You Gentille Plumbing and Heating"

"I called the company on Sunday evening and they responded promptly early in the morning. My system was installed by them 3 years ago but somehow I missed last year's annual servicing. With the current heat wave it was severely underperforming. They sent out Robert Duclos within the hour. He diagnosed the problem---not enough Freon in the system, grass and mulch build-up in the compressor, valves buried under the landscaping--and fixed it all for the price of the annual service contract. I would definitely recommend them for anyone needing central a/c work."

"Replaced my water heater in an emergency and went tankless. Super happy with the entire team. They provided me temporary hot water and came back the next day to put on the tankless water heater. They gave me options and I’m happy with going tankless"
