Duda Enterprises

A homeowner called in August 2024 for an estimate to replace their furnace — other companies had told them the part it needed was no longer made. David looked it over, told them the furnace did not need replacing, and replaced the part instead. A customer writing in August 2021 tells a similar story about a 30-year-old boiler that broke on a winter weekend: he was out within a day, fixed it, and has kept it running since rather than selling them a new system. Duda Enterprises is David Duda's residential HVAC company in Quincy. It says it has worked the trade here since 1998, handling air conditioning, furnaces, ductless mini-splits, ductwork and oil heat with emergency availability around the clock, and that it is an authorized Mass Save heat pump installer. Dave takes the calls himself; a March 2026 reviewer names Matthew working alongside him. Speed in a crisis comes up constantly. In August 2022 an air conditioner died during a heat wave and the customer, braced for a long wait, got a call back straight away and Dave at the door within the hour. In February 2023 a burner quit and he was out to Stoughton inside an hour. In July 2023 a broken AC was running again in thirty minutes, and that customer later had a ductless mini-split put in. When a caller's thermostat failed in the middle of January 2026, he came the same day and confirmed what the owner already suspected: the 40-year-old unit had reached the end. The extras are what people write about afterwards. A January 2025 customer whose heat stopped had old wiring replaced and, on top of that, an automatic water feeder that had never worked finally put right. A March 2026 customer called about a pressure problem in the heating system and had the small things sorted too, with everything checked over before the crew left. Across 31 Google ratings the average is 4.8, and the written accounts reach back to 2021. The company's own site names Quincy as its service area, though reviewers write from Randolph, Stoughton and elsewhere on the South Shore. If your system is old and you would rather be told honestly whether it can be saved, this is the kind of shop to call — particularly for a breakdown in a heat wave or a cold snap. Ask what an after-hours call costs, and whether a heat pump quote runs through the Mass Save rebates the company says it is authorized for.
