Our boiler broke and Duffy got us one and installed the next day to give us heat and hot water.The company where they got the boiler from was here and oversaw to make sure everything went ok. Great customer service and the guys who installed went above and beyond. So nice and polite and efficient. They even did extra work and got heat to work in a room where the baseboard heat didn't work. Installed all new thermostats too. Great company and would highly recommend. Thank you Duffey

Been using Duffey since we bought our house in 2019 (they installed the boiler prior to us owning). Been very happy with their service.

Everything works great and they cleaned up after as well. 100% recommend

The install was quick, efficient, and the technici... read more

We just had our house heater replaced two days after we called Duffey. We have used them previously and their first class service is reliable, efficient and remarkable. Everyone on their team is professional and personable. Top shelf company that will always be our first call when we need repairs. Thank You Duffeys!! Ann and Jim
