J. Griffin Heating Plumbing & Cooling Peabody

Call J. Griffin in a panic — literally: one Peabody homeowner phoned after their carbon monoxide detectors went off in the middle of the night, and the crew traced it to a dying furnace, sourced a replacement, and had heat and safety restored the same day. That's the throughline across the company's 34 Google reviews, every one of them five stars: a family-owned heating, plumbing and cooling shop working out of Peabody and North Reading, covering both emergency calls and routine installs across Eastern Massachusetts and southern New Hampshire, per the company's own site. The jobs on file range well past furnaces — tankless and Navien water heater work, minisplit maintenance, gas dryer hookups, a condenser swap, a frost-free outdoor faucet upgrade, new thermostats — and a handful of names keep showing up across reviews (Jeremy, Tom, Jeff, John), which points to a small, steady crew rather than rotating subs. Repeat customers show up too: one used the company for a boiler job and came back for a furnace repair, calling both visits good; another says they've used J. Griffin "for quite a few years." A Nextdoor poster with no apparent tie to the business separately named them as the go-to for a microwave installation in the Methuen area. There's nothing negative in the record to weigh against any of that — the review history runs clean through the last six months with no complaints. The trade-off is that most of the write-ups are short ("great service," "very professional") rather than blow-by-blow accounts, so the read leans more on consistency and volume than on deep documentation of any single repair. Before booking, it's worth confirming which location — Peabody or North Reading — would handle the job, and that the specific trade needed (plumbing vs. HVAC) is covered by whoever's on call that day.
