Best fuel supplier in South Hadley, Massachusetts (MA) 2024

Rinnai Tankless on-demand hot water heater installed: I was so pleased with the service I received from FSi. Jason responded promptly to my request for an estimate and answered all my questions almost immediately. The plumber was careful and efficient. After the installation they checked in to make sure everything was working well. I love my new hot water heater, and am very happy with the price and the service. These guys are my new plumbers for sure! ~Avril
