What Our Customers Are Saying

⭐⭐⭐⭐⭐
"Knowledgeable, Friendly, and Trustworthy"
Norman Cantara – Google – July 15, 2025
“The young man Kevin, who cleaned our furnace today, was a wonderful and very pleasant guy. We hope to have him again next year because it’s always a pleasure to have someone explain things to us—we felt very comfortable with him. The office staff, in person and on the phone, were also very, very nice when we signed up to pre-buy our kerosene. Very happy with the service of this company.”

"They Showed Up When We Needed Them Most"
Jeffrey H – BBB – March 20, 2025
“Garthwaite's entire team... All rock stars. My wife came home to a furnace fire caused by a leaky valve. Their tech arrived that very night—fast, calm, and professional. Can’t thank them enough for their quick response and quality work.”

"Excellent Installation, Friendly Service"
Steve Irza – Google – November 29, 2024
“We converted from oil to propane for heat and hot water at our Drakes Island home. Garthwaite handled the purchase and installation of our ALTA combi boiler and tankless hot water heater. Excellent service—and a real person answers the phone! Very happy with the experience.”
