J. Griffin Heating Plumbing & Cooling Peabody

A homeowner woke in March to carbon monoxide detectors going off. J. Griffin came straight out, traced the leak to the furnace, found a replacement unit and booked the swap. Same-day is ordinary here: a toilet repaired the day it was called in, heat and hot water back on the morning they quit for a customer who has used the company for years. J. Griffin describes itself as a family-owned heating, plumbing and cooling business working out of North Reading and Peabody, covering Eastern Massachusetts and Southern New Hampshire, and says it is a Mass Save program partner. The jobs customers describe run right across those trades — a tankless water heater system installed in May, annual service on a Navien water heater alongside a mini-split inspection in April, a condenser replaced in a tight spot in March, a gas dryer hooked up, a whole-house water filter fitted, thermostats and a dryer vent, and an outdoor faucet upgraded to frost-free before winter. Technicians get named, and the same names keep coming back. Jeremy, credited in May with doing the maintenance and then explaining every bit of it. Tom Pags, who a April customer says arrived on time, did both the mini-split and the water heater, and left every area spotless. Jeff, who a March reviewer says texts back on urgent matters. John, Josh and Dylan turn up too, usually alongside a line about explaining the work before starting it. Its Google page sits at 5.0 from 47 ratings, and every written review on file was posted in 2026, 28 of them since March — a short, consistent run rather than a long history to read back through. For a no-heat morning in Peabody or North Reading, this is a straightforward call: they answer, they show up, and the people who come explain what they are doing. If a furnace or heat pump replacement is on the table, ask what the Mass Save partnership actually gets you in rebates before you sign.
