Eric C. Shaw Mechanical

Eric C. Shaw Mechanical is a Chelmsford heating and plumbing company that says it specializes in high-efficiency heating equipment, new and retrofit, for homes and businesses from Tewksbury and Andover to Lowell, Concord and Boston. Its Massachusetts plumber licence (4781-PL-C) is active on the state registry. It has 19 Google ratings averaging 5 stars, and the company reports 11 years in business. In July 2026, a customer praised the company's proactive communication and on-time arrivals, and a May 2026 customer called all the work super clean. In a December 2025 review, a customer said Eric replaced a gas furnace and hot water heater, explained the new digital system and cleaned up afterward, and an October 2025 reviewer called a furnace repair very reasonable. In an October 2024 review, a customer with a leaking hot water tank said the plumber ordered a new one right away, it arrived the next day, and he installed it a couple of hours later. In a December 2022 review, a customer who left a web request on a Sunday evening said Eric responded early Monday and fit them in that afternoon; he and Mike fixed a bathroom leak, evaluated the heating system and programmed a new thermostat, and Eric explained Mass Save options. A May 2022 review from the Waltham Housing Authority described the company's HVAC response there and said it stands behind its work with a labor and materials warranty.
