Frederick Plumbing and Heating **Trade:** Plumbing · **Address:** 1625 Washington St Unit C, Holliston, MA 01746, USA · **Phone:** (508) 282-9881 · **Website:** http://jafrederick.com/ · **Languages:** English **Rating: 3.4/5** (medium confidence) — from 10 reviews across 5 sources. 80% of sentiment-scored reviews read net-positive. Last 6 months: 4 reviews, 0 negative. ## The honest read 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. **Strengths:** - Fast emergency response — sewer leak fixed within an hour of the call - Clean recent record — four 2026 reviews all cite quick, friendly service - Registry-verified license — active Massachusetts plumbing license **Concerns:** - Serious 2023 complaint — months of frustration, one reviewer's first-ever review - Wiring left exposed — a 2023 review describes an undiagnosed thermostat repair ## Claims & citations Every claim below is backed by real evidence rows — uncited claims are dropped in code before publication. - Responded to a major sewer main leak within an hour of being called and completed the repair. _(confidence: medium)_ - [Google Reviews](https://www.google.com/maps/reviews/data=!4m8!14m7!1m6!2m5!1sChZDSUhNMG9nS0VJQ0FnSUQ2X0s2UkJ3EAE!2m1!1s0x0:0xb003eabe027e8189!3m1!1s2@1:CIHM0ogKEICAgID6_K6RBw%7C%7C?hl=en) — “5★ We had a major main line sewer leak in the basement ,I called JA Frederick plumbing and he sent someone out within an hour ,the leak was …” - Got a customer's AC repaired the same Sunday evening after mice damaged the wiring, despite the call coming in outside business hours. _(confidence: medium)_ - [Google Reviews](https://www.google.com/maps/reviews/data=!4m8!14m7!1m6!2m5!1sChZDSUhNMG9nS0VJQ0FnSUNyeWFqREx3EAE!2m1!1s0x0:0xb003eabe027e8189!3m1!1s2@1:CIHM0ogKEICAgICryajDLw%7C%7C?hl=en) — “5★ Mice chewed through wiring on my AC, but I didn't know that when I came home to an 85°F house on a Sunday evening. 7am on Monday I starte…” - The four most recent Google reviews, all from 2026, describe fast response and friendly service. _(confidence: high)_ - [Google Reviews](https://www.google.com/maps/reviews/data=!4m8!14m7!1m6!2m5!1sCi9DQUlRQUNvZENodHljRjlvT205S1QwZHlORWhSYUdNMVl6WmtibkJtV0UwMFJtYxAB!2m1!1s0x0:0xb003eabe027e8189!3m1!1s2@1:CAIQACodChtycF9oOm9KT0dyNEhRaGM1YzZkbnBmWE00Rmc%7C%7C?hl=en) — “5★ Great service!” - [Google Reviews](https://www.google.com/maps/reviews/data=!4m8!14m7!1m6!2m5!1sCi9DQUlRQUNvZENodHljRjlvT2xWV1ptVTFUeTE2ZW1KNWNrcGxjMWhvWW1aT1NVRRAB!2m1!1s0x0:0xb003eabe027e8189!3m1!1s2@1:CAIQACodChtycF9oOlVWZmU1Ty16emJ5ckplc1hoYmZOSUE%7C%7C?hl=en) — “5★ Great and friendly service on my AC system.
