## The honest read

GEM Plumbing & Heating has become one of the busiest names in Massachusetts home service, and its 4.8-star average across 917 Google ratings — with about 650 written reviews collected since 2024 across six sources — points to a company running at real scale. Based in Raynham, it fields separate crews for plumbing, HVAC, electrical and water quality work, and its Massachusetts HVAC license is active on the state registry.

Of the roughly 156 reviews posted in the last six months, only four were negative, and the ones that stand out are the emergency calls. A technician named Nick showed up within the hour for a $199 flat emergency fee on Christmas Day to fix a dead furnace, walking the homeowner through how it worked before he left. A January 2026 review described a same-day fix on a gas steam boiler after a different installer had made things worse, and in July 2026 a plumber named Joseph B. replaced a blown hot water tank the same day it burst. Individual technicians get named again and again across trades — Nicole Tradd for plumbing and water testing, David S. for a stopgap HVAC repair followed by a next-morning fix, Corey Mayo for tracking down a hard-to-find part on a split AC system, and Dory and Kevin for untangling a wiring problem that turned out bigger than expected.

The recurring complaint, though, is price. Independent 1★ reviews spanning 2024 through mid-2026 describe being quoted $800-plus for a capacitor that costs under $50, a $149 fee charged when no repair was actually done, and a shower-head fix that was billed as a full-part replacement — one reviewer flatly called it a fleecing. A November 2025 review also described a technician sent without the copper pipe and couplings the job needed, a dispatch mix-up that left the home without heat for three days. BBB lists the company as accredited with an A- grade, but also shows 48 complaints on file — worth pinning down pricing in writing before any repair beyond a routine diagnostic.

For plumbing, HVAC and electrical work, GEM's size means a same-day or even same-hour response is realistic, and the technician-level praise is consistent across services — but get a firm, itemized price before work begins.

**Strengths:**
- Christmas emergency — arrived within the hour for a flat $199 call
- Same-day fixes — replaced a blown hot water tank the day it burst
- Persistent troubleshooting — tracked down a hard-to-find part for a second AC issue
- Named technicians — same names praised repeatedly across plumbing, HVAC and electrical work

**Concerns:**
- Price complaints — several 1★ reviews describe being charged well above parts cost
- Dispatch mix-up — a tech arrived without the parts needed, leaving no heat 3 days
- Fee disputes — a customer was charged $149 despite no repair being performed
