J.A. Frederick Plumbing and Heating

J.A. Frederick Plumbing and Heating is a Milford-based shop that Jeffrey Frederick has operated since 1997 — 29 years serving the I-495 corridor towns around Holliston and Milford, formally incorporated as an LLC in 2024. The recent record is clean: the last four Google reviews, all from this year, describe fast response and friendly service on jobs ranging from a leaking pipe to an AC repair. Older reviews show a business capable of real emergency response — one customer had a major sewer main leak fixed within an hour of calling, another got same-day help on a Sunday evening after mice chewed through AC wiring in an 85-degree house. The one thing worth knowing: two detailed one-star reviews from January 2023 describe a much worse experience. One customer, writing their first-ever review, says the company cost them months of frustration and money; another describes a technician who took apart a malfunctioning thermostat, left exposed wires, and couldn't diagnose the problem. Both are several years old now and sit apart from an otherwise positive record before and since, but worth asking about directly if a job touches electrical or thermostat wiring. The company holds an active Massachusetts plumbing license, verified directly with the state, and the Better Business Bureau lists a second Division of Professional Licensure number for the business that wasn't independently checked. It's BBB-accredited with an A+ grade and says on its site that it's MassSave Certified with 24/7 emergency service. For straightforward plumbing and HVAC calls — especially urgent ones — the recent reviews back up the pitch; for wiring-adjacent work, it's worth confirming who's doing the job and how, given the 2023 complaints.
