Just can't recommend them enough!!!! 3 Brothers did a…read moreawesome job of installing a master bath, and repairing my A/C in my old house. We just moved and wanted to do some major updating/upgrading. So far they have added a water line and drain for the washer, a new water line for the new fridge, a gas line for the new stove, and a slop sink in the basement, which required a pump. They showed up promptly, were courteous, professional, and when they were done, cleaned up not only what was there because of them, but vacuumed most of my basement. They will be coming back to update our master bath, just as soon as the supplier can get the parts. Come summer time, I'm sure they will be here to service my A/C, and come winter to service my heat. Simply the best!

I had to get an electric water heater replaced in my condo…read more It was not leaking so I was not in rush but condo required old ones replaced. I called Eric and he scheduled the replacement at a reasonable cost. Wayne came on the day of appointment and drained old one. As they were working I realized condo had listed automatic shutoff valve. That was way expensive part and needed electric outlet which we didn't have. Wayne had to re-connect electric wires and refill the water heater and they had to leave. I complained to condo and they agreed that automatic valve was optional. Wayne came back next day and installed the water heater. They did not charge more for extra trip. Very professional work and honest people.

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.

Although parts for our hot water heater were still under warranty, David's Heating and Cooling…read morequoted us over $900 in labor to get it fixed--a sum that exceeded the cost of replacing the unit altogether. The problem turned out to be a simple pilot light issue, yet their approach made it clear that running up labor charges took priority over taking care of the customer. Communication was poor throughout the process, and when we attempted to call for resolution, the woman who answered the phone hung up on us. As the President of a company that employs a large blue-collar workforce, I understand labor costs--but I also understand honesty, fairness, and professionalism. This company failed on all three fronts. We ultimately called Locher Plumbing, who were professional, communicative, and ethical. They quickly ordered the necessary part, returned for installation, and charged a fraction of what David's Heating and Cooling demanded. Locher proved that doing right by the customer is possible, and they earned our trust and future business. I cannot recommend strongly enough that others avoid David's Heating and Cooling.

Your lives are worth it! Pierre hands down is the best technician at David's. He's honest, trustworthy and competent. He fixed all our problems for $500. It was well worth it to have peace of mind entering the heating season.
