Green Tech Plumbing & Heating

Across nearly 500 Google reviews, Green Tech Plumbing & Heating keeps showing up for the same kind of call: something failed overnight and someone needed it fixed today. The Somerville company handles plumbing and HVAC work throughout the Boston area — Cambridge, Medford, Malden, Charlestown, South Boston, even as far as Natick — and its reviews read less like a service log and more like a list of near-misses solved on short notice. The numbers back that up: 494 Google ratings average 4.8 stars, and the tone across dozens of recent reviews skews strongly positive. In the past six months alone, 63 reviews came in with only 4 negative. Two technicians, Dave (also called David) and Hector, get named directly and repeatedly — customers describe them walking through options before starting work, wearing shoe covers, and explaining what broke and why rather than just fixing it and leaving. When an AC unit died in a heat wave, a pipe froze in a cold snap, or a heater quit on a Sunday night, several reviewers say a technician showed up within an hour or two. The friction shows up around money on a handful of jobs. One customer paid a $100 diagnostic fee plus $300 for central air maintenance, then watched the system fail again shortly after — and says calls and texts went unanswered from there. Another paid $475 for a water pressure fix that a 15-minute visit didn't actually change. A third went through three separate booking fees and over $1,000 trying to get a Navien tankless water heater working, and says a second plumber later found a burned-out heat exchanger — the kind of failure that shouldn't happen if the original repair held. These are a minority against the steady run of same-day, five-star visits, but specific enough to plan around: get a firm price before work starts, and ask what happens if the same problem comes back. For a plumbing or HVAC emergency in Somerville and the surrounding towns — a burst pipe, a dead water heater, an AC that quits in July — Green Tech is the kind of company people call and get an answer from fast. Before booking, it's worth asking for a not-to-exceed price on diagnostic visits and getting any repair warranty in writing.
