716 Google ratings averaging 5 stars, and a family behind the counter: J. Griffin Heating Plumbing & Cooling is a North Reading heating, cooling and plumbing company that founder Jeff Griffin, per the company's site, opened after 27 years at a Massachusetts utility and now runs with his sons Jeremy and Josh. Recent jobs cover a wide range. In a July 2026 Google review, a homeowner whose carbon monoxide alarm went off said the company diagnosed the problem and installed a new furnace on the homeowner's schedule. Another that month credited Tom and his crew with rebuilding a furnace flue and replacing an oil tank, and a June 2026 reviewer had a leaking hot water boiler replaced. Earlier, in September 2021 and August 2022 HomeAdvisor reviews, customers described Jeff handling oil-to-gas conversions, removing old oil burners and installing new boilers and water heaters. A November 2025 Google reviewer said two technicians spent an hour clicking the pilot light and left the furnace still not working. A September 2025 reviewer praised Tom's work but said the $419 bill was 2.6 times what the same job cost a year earlier. A September 2021 Angi reviewer called the plumber a good talker who left knowing the job was not finished correctly, and said they had to hire another plumber. The BBB grades it A+. The state registry shows its Massachusetts plumber licence, 4342-PL-C, as active.
