Eric C. Foster Plumbing Heating & Cooling Inc.

Eric C. Foster Plumbing, Heating & Cooling has been a family business in Chelmsford since 1978, when Eric and his wife Debbie started it out of their home; the company expanded into HVAC in 2011, and Eric's sons Jared, Todd, and Travis are now part of running it. It holds an active Massachusetts plumbing license and an active Massachusetts HVAC license, both verified with the state registry, and the company says it covers Chelmsford, Concord, Nashua, and Boston. Their Google history runs deep — 463 reviews dating back to 2021, averaging 4.9 stars, with 61 posted in just the last six months. The recurring theme is speed on emergencies: one customer found water on the basement floor around noon and had a new water heater installed by 5:30 that same day; another called about a leaking pipe and had a technician out within a few hours. Reviewers name specific technicians often — Mark, Nate, Shane, Rob, and Kyle turn up repeatedly, usually praised for walking customers through the diagnosis in plain language rather than just doing the work and leaving. One longtime customer described being a Foster client since 1976, having had a heating system, water heaters, and gas conversions done over the decades. The company has also come up by name in a Chelmsford-area Reddit thread, where one commenter who'd hired them called the work excellent. A few reviews worth knowing about: in a May 2026 review, a customer wrote that a water heater installation was left with the plate over the electrical wire not properly seated, and was told to call an electrician to finish it. Another customer that same month said a technician arrived without the anode rods needed for a water heater repair. And in a January 2026 review, a customer called the work expensive, said the office was slow to return quotes after asking three times, and felt the phone staff were curt — a more critical account than the rest of the record, standing apart from the pattern of same-day, explained-clearly service most reviewers describe. For a family-run Chelmsford shop with decades in business and reviews running deep across both plumbing and heating work, this fits homeowners who want one call for anything from a burst pipe to a new boiler. Worth confirming: pin down the quote and any parts needed before the truck rolls — a few accounts describe installs needing a follow-up visit.
