The original contractor had come out but did not resolve the issues which included improper date/time readings at the thermostat and no automatic switchover of the heat pump to the furnace and vice versa at a predetermined outdoor temperature. Justin determined that the outdoor sensor had not been set up properly on the heat pump, and that the thermostat needed an app so that it would read proper date and time as well as proper outdoor temperature so that the equipment switchover would work properly. I was very satisfied with Justin's professionalism and thoroughness in diagnosing and fixing the issues we had with our HVAC system. I am very pleased with the results and would recommend Key HVAC to my family and friends.

Two years ago they replaced one of our furnaces which had outlived its useful life. Last winter (2026) the furnace heating our upstairs, located in our attic, died.

Access was not easy as it required climbing a ladder in a bedroom closet and going up through a small opening in the ceiling. I don't know how the men were able to take the old equipment out and install the new furnace but they did it. We couldn't be happier with the service Simmons Plumbing & HVAC provides.

We switched an oil account to Haffner/Energy North from another local provider. We also had them…read moreinstall a new Oil furnace/boiler. While oil delivery service has been satisfactory, the install was overpriced and raised questions about the integrity of Haffner's/Energy North. We had a proposal from our former dealer to install a Buderus boiler based system. I asked the Haffners team for a proposal and price to install a system of equal quality and especially efficiency. Haffner's proposed to install a Peerless boiler based system. In multiple discussions, that system was represented to be of the same quality and efficiency as the Buderus. Those representations proved to be not accurate. I later learned that while Peerless is a very well regarded brand, it is of lesser quality and lower efficiency than the Buderus. This first came to light when one of the Haffner's technicians who installed the Peerless system acknowledged those facts in conversation after the install. I was very disappointed and immediately raised concerns about the inaccurate statements and the lack of value in what Haffner's had installed. They "met the price" of the Buderus proposal [their original price was higher for the Peerless system]. When I challenged Haffner's supervisory staff, they offered a $100 dollar price accommodation. Given the discrepancy in value and efficiency, that did not begin to make up for the inaccurate statements we relied on in accepting their proposal. This was a system for a 95 year old widow, they should have been more honest. I ultimately spoke with a neutral party about the comparison between the two boilers - a 30+ years in the business plumbing and heating professional who has worked in my home [the system at issue was for my elderly mother] for two decades. He said while Peerless is a good quality unit, it is not at the level of the Buderus. He said in his entire career, he never had experienced a defect in a Buderus device. He also explained the difference in efficiency. In the peerless boiler, heat is transferred in a single pass around a heated chamber. The medium to be heated in the Buderus system passes three times, transferring more heat for each unit of oil burned. That information only increased my disappointment with what Haffner's's/Energy North represented to me and how they treated my mother once the inaccuracies and unfairness were brought to their attention. Conclusion: Good service and low oil prices. But pay attention to what is represented about equipment quality and efficiency. In retrospect, we should have stuck with the competing local dealer and installed the Buderus based system.
