Two trades in one van is the shape of this business, and in the Boston area that combination makes practical sense. Steam and hot water boilers, gas lines, old cast iron waste stacks and window-unit-to-mini-split conversions all sit in the same buildings, often in the same basement. Green Tech Plumbing & Heating works out of an address on Middlesex Avenue in Somerville and says it covers Middlesex and Suffolk counties, which takes in Cambridge, Medford, Malden, Everett, Charlestown and much of Boston proper.

The published service list is long. On plumbing, it runs to residential repairs, leak detection, water heater work, water treatment and filtration, toilet and faucet repair, sump pumps, pipe and gas leak repair, garbage disposals, drain cleaning and backflow prevention testing. Heating and cooling covers boiler service, furnace installation and repair, heat pumps, ductless mini split installation, AC installation and repair, humidifiers and indoor air quality equipment. The company describes itself as licensed, bonded and insured with more than twenty years of experience, and says it offers financing, a service membership and a referral program. Those are the company's own claims, worth confirming directly, though the licensing point is straightforward to verify since Massachusetts publishes plumbing and gas fitting licence lookups online.

Reviews give a useful counterweight to marketing. The Google Business Profile showed 4.8 from 522 reviews when read on September 4, 2026. Five hundred plus reviews is not a small sample, and a 4.8 across that many jobs suggests a consistent field crew rather than one strong technician. Read a handful of the more recent ones and look at what people say about pricing conversations, because that is where plumbing complaints usually cluster.

Where green tech plumbing heating fits best is the middle band of residential work. A leaking water heater in a Somerville triple-decker basement, a boiler that will not fire on the first cold Sunday in November, a kitchen line that backs up into the sink, a mini split system for a third-floor apartment with no ductwork. Emergency availability is a genuine part of the offer here: hours are posted as open around the clock every day, and the site mentions a live answering service rather than voicemail. If you have ever stood over a spraying supply line at eleven at night, that difference matters.

Who it is less obviously suited to is harder to judge from public information. Large commercial mechanical projects, multi-building sewer replacement and heavy excavation are not called out in the material, so anyone with a job of that scale should describe it plainly on the first call and ask whether the company self-performs or subcontracts. Same goes for anything involving a shared sewer line between condo units, where responsibility and permitting can get tangled.

Local conditions shape a lot of this work. Somerville and its neighbours are dense, with narrow driveways, shared basements, converted two and three families and heating systems that have been patched by four owners. Gas fitting requires a licensed gas fitter and a permit pulled with the city inspector, and a boiler or water heater replacement should include that permit and an inspection. Ask about it. A contractor who treats permitting as optional is telling you something. Ask too about venting when you replace a heater or furnace, because swapping an old atmospheric appliance for a high-efficiency unit can leave an orphaned water heater on a chimney flue it can no longer safely share.

Before booking, get the practical details settled: the diagnostic or trip fee and whether it applies to the repair, the after-hours rate compared with the daytime rate, what the manufacturer warranty is on any installed equipment and what labour warranty comes on top, and who handles the Mass Save rebate paperwork if you are installing a heat pump. Written estimates before work begins are the norm for reputable shops in this market, and the company says it provides upfront pricing.

Compared with the alternatives around Boston, green tech plumbing heating sits between the one-truck operator who is cheap but booked three weeks out and the large regional franchise with dispatchers and flat-rate books. The review count points to a real crew and real volume. The broad plumbing and HVAC range means one relationship instead of two, which is worth something when the same basement holds both problems.
