J. Griffin Heating Plumbing & Cooling

J. Griffin Heating, Plumbing & Cooling works out of 50 Main Street in North Reading, Massachusetts, and homeowners hire the company for the systems that fail at the worst moment: boilers, furnaces, water heaters, central air and everyday plumbing repairs. Reviewers describe it as a family-owned operation, and the Griffin name shows up on the vans and in the reviews alike, with Jeremy and Joshua Griffin both named by customers for jobs they ran themselves. The track record is deep and current: 204 reviews are on file from 2021 through 2026 across four sources, and Google alone carries a five-star average from 716 ratings. What recurs is speed on urgent work. One homeowner's hot water heater failed late at night, Jeff came out that night and returned the next morning to install the new tank. Another had a leaking tank quoted the same day and the replacement done first thing the following morning. A third called and was booked for the next day, within the estimated window, with the repair finished in about thirty minutes. When a carbon monoxide alarm went off, the company diagnosed the problem and had a replacement furnace running on the homeowner's own schedule. The crew is named again and again, which is unusual and worth weighting: Tom rebuilding a furnace flue and replacing an oil tank, Jeremy and Ray on HVAC maintenance and a hot water tank flush, John and Delia on repairs with what one customer called clear communication throughout. Navien equipment comes up specifically — a thorough annual service on a Navien gas water heater in July 2026, and in a January 2026 review an urgent Navien boiler repair handled quickly. Several reviewers single out being walked through options without pressure; one noted there were no attempts to upsell equipment. Two things are worth asking about before you book. Price reads mixed inside otherwise happy reviews: one June 2026 customer thought the price was high, while others call the pricing reasonable and one April 2026 heat pump customer said they had the best price in the area — so get the quote itemised. And in a November 2025 one-star review, a homeowner said a technician spent an hour clicking the pilot light without a real diagnostic and the furnace still did not work; if your call is a diagnosis rather than a straight replacement, ask who is coming and what the diagnostic process is. For a North Reading or North Shore homeowner facing a dead boiler, a failed water heater or an AC system that needs replacing, this is a strong first call.
