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.
