D F Plumbing & Mechanical is a Belchertown shop built for plumbing and heating problems around the Pioneer Valley: water heaters, boilers, gas piping, and the hydronic systems that keep older New England homes warm. The company, run by owner David Fredenburgh, says on its own site it has served the area for 25 years, and its BBB profile puts the figure at 31 — either way, this is a long-tenured local operation, not a startup. What keeps showing up in its reviews is speed paired with follow-through. Google shows a 4.7-star average from 31 ratings, and the written reviews on file — 14 of them, all five stars, running from 2021 through 2025 — repeat the same names: Dean, Rob, Joe, Richie. In an October 2025 review, a customer described calling eight other companies about a failed geothermal heat-pump compressor and getting nowhere, until Dean walked them through a phone bypass to get hot water back for the weekend and followed up by email to spec the right replacement unit. A 2021 review told a similar story about pricing rather than access: an estimate for a well sediment filter came in over the phone, and the final bill landed at the low end of that quote — "fair price for a good job," the reviewer wrote. The company's reach goes beyond routine house calls, too. In 2017, a Belchertown-based DF Plumbing crew installed plumbing during the redevelopment of the old Northampton State Hospital into condominiums at Village Hill — the kind of institutional job that speaks to more than a two-person outfit doing water heaters. A couple of things are worth asking about directly rather than assuming. The BBB lists the company at an A+ grade but notes it is not an accredited BBB business, which is a different thing than the grade alone suggests. And the tenure claim is worth confirming, since the company's own site and its BBB listing don't agree — 25 years by one count, 31 by the other. For anyone in the Belchertown-to-Northampton corridor dealing with a water heater, boiler, or gas piping job — especially one other companies have waved off — this is a shop with a real paper trail of getting people unstuck. Confirm current licensing and get a firm quote before the truck rolls, since neither one is stated outright online.

I had a Geothermal hot water heater that the compressor went on. After calling 8 companies and able to get anyone to speak with me, I stopped in at DF Plumbing and Dean talked me through bypassing the Heat Pump mode so that I could have hot water for the weekend. When I returned home and performed the bypass then e-mailed pictures to Dean so that he could provide me with the correct hot water heater for my needs then confirmed with me that I did have hot water and that he did not need to make an emergency home visit. Dean then provided me with an estimate for a new Hybrid Hot Water Heater. On Monday Dean called to advise that he would have a crew at my home on Tuesday to install the new hot water heater. On Tuesday Dean called to advise that his crew would be at my home within an hour. His crew was so awesome. Their work was neat, they cleaned up after they were done and did some of the nicest work I have seen and made sure all pipes were secured, that the water was on and running properly and took away my old unit. These people are my new best friends and I would use DF Plumbing and recommend the any day of the week. This organization is just the best and awesome. I give them 10 stars out of 5. They are that good.
DF Plumbing. Always reasonably priced, friendly, and consistent with our plumbing needs. I recently had a countertop installed but wanted the same sink. Richie removed it and put it back, replacing a few parts along the way. THANKS DF PLUMBING!
DF Plumbing have helped with a few of our plumbing needs over the last couple of years. They have always been quick to respond and are very knowledgeable. The most recent experience was particularly amazing. Not only were they able to squeeze our job in a few days earlier than expected, the workers who came, Joe & Sam, were outstanding: knowledgeable, outgoing, quick, helpful & all with a positive attitude!! We'll definitely be calling them again for any future needs.
Needed a new tankless water heater and DF Plumbing installed very quickly and efficiently. Answered all questions we had and Dean went above and beyond by helping explain our situation to Quabbin Analytics next store when I went in person to inquire about well water testing. Highly recommend!
Great Service from Rob and his team. The job was covered by our manufacturer warranty and DF was on site within a few hours of our call. We will be back again.
