Jeffrey P. Griffin

J. Griffin Heating and Plumbing is Jeff Griffin's company, and the work customers describe most often is taking an old oil system out of a house and putting a high-efficiency gas boiler in its place. A March 2022 homeowner had a very old heating system replaced with a high-efficiency boiler after finding him through HomeAdvisor. A May 2022 customer had the old oil equipment and the tank removed as part of the swap and called the attention to detail second to none. An August 2022 reviewer describes him handling the whole oil-to-gas conversion — the gas meter, the inspection, and the boiler and water heater — and a 2021 customer whose 24-year-old oil furnace was replaced said the crew organised the permits and timeline as well. Several accounts turn on what he recommends rather than what he sells. An April 2021 customer said the heating design was built around the family's needs rather than the most expensive product, and a 2021 reviewer replacing a 45-year-old furnace said Jeff was the only one of several companies to ask how long they planned to stay in the house. A June 2022 customer was told how the furnace and zones would be designed, got a water heater at no extra cost with the available rebates, and had the installation done in a day and a half. Smaller and urgent calls appear too: a February 2021 customer with a complicated boiler no one else could work on had him come out the same day, another in 2022 credited him with stopping pipes from bursting on a $16,000 job, and a May 2021 reviewer describes the team coming back on a Friday night to follow up on a problem. The most recent accounts are shorter — an April 2025 customer had a water heater in within two hours but described some hiccups along the way, and rated the job four stars. One account runs the other way. In September 2021 a customer said the plumber left a radiator job unfinished and they hired someone else; the owner replied at length, saying the radiator was installed as asked and working, and that a follow-up email had gone astray. That is the single negative in a record of 27 accounts running from 2015 to 2025, against 4.9-star averages from 245 ratings on both Angi and HomeAdvisor. For a heating replacement or an oil-to-gas conversion the written detail is unusually specific; get the scope and the follow-up terms in writing, as the disputed job suggests.
