GEM Plumbing and Heating

GEM Plumbing and Heating is a large, long-running HVAC, plumbing, and electrical company headquartered in Raynham, with branch offices across Rhode Island, Massachusetts, and Connecticut — over 700 employees and roughly 500 trucks on the road. The company says it was founded in 1949 by Larry Sr. and Gloria Gemma and describes itself as family-led today, though independent reporting names HomeX Services Group LLC as its parent company as of a 2023 Providence Business News article — the "family business" framing sits alongside real institutional ownership behind the scenes. Google shows 1,011 ratings averaging 4.8 stars, and the pattern across dozens of recent reviews is speed and communication. Homeowners describe technicians arriving the same day for a dead water heater or a failed AC condenser, walking through the diagnosis before starting work, and cleaning up after themselves; several single out individual technicians by name for explaining a repair in plain language before doing it. One recent review described a team replacing rooftop AC units across two condo units, coordinating closely with a crane crew and an electrician. Not every account is glowing. A 2026 one-star review described a sewer pump replacement that ran past $3,200 in diagnostic and repair fees and then failed again within a month; a separate two-star review called the charge for a ten-minute install excessive. The BBB rates GEM A- and lists it as accredited, but also shows 50 complaints on file — a real number, worth weighing against a company handling this much volume. GEM's Massachusetts plumbing license (2763-PL-C) is active on the state registry, and the company offers free estimates on new installations along with 24/7 emergency service. For a homeowner in Raynham or nearby who needs a fast HVAC or plumbing fix, GEM is a large, established operation with a strong recent review record. Worth asking for a firm price up front given the handful of billing complaints, and worth knowing it now operates as part of a larger corporate group rather than purely as the family shop its marketing describes.
