# J.M. Mechanical Services, Inc **Trade:** HVAC / Heating & Cooling · **Address:** 172 Orleans St, East Boston, MA 02128, USA · **Phone:** (617) 561-4733 · **Languages:** English **Rating: 3.5/5** (medium confidence) — from 8 reviews across 7 sources. 88% of sentiment-scored reviews read net-positive. Last 6 months: 1 reviews, 1 negative. ## The honest read J.M. Mechanical Services handles plumbing and heating work out of East Boston, and its BBB profile backs up the tenure customers describe: an A+ grade and 30 years in business, with no complaints on file. Google shows 4.1 stars from 11 ratings. The reviews that go into detail describe a company that shows up for the cold-weather emergencies. In a December 2024 review, a customer said JM Mechanical fixed a burst cellar pipe the same day it happened, in the middle of a cold snap. In a July 2024 review, technicians Paul and Mike were credited with troubleshooting a furnace pilot light that went out after National Grid swapped a gas meter, replacing a part and walking the homeowner through what they did. One customer, in a February 2026 review, said they'd used the company for about 20 years and that the work — and the willingness to stand behind it — never wavered. The most recent review, from June 2026, breaks from that pattern: it calls the service poor, the bill outrageous and the attitude bad, without further detail on the job involved. For East Boston plumbing or heating repairs — a stuck furnace, a burst pipe, a stubborn toilet — the longer written history points to responsive, explained work; the one recent complaint is worth asking about directly if pricing is a concern. **Strengths:** - Long-time customer — a 20-year customer says they always stand behind their work - Same-day emergency fix — repaired a burst pipe in cold weather the day it happened - Furnace troubleshooting — technicians relit a pilot light and explained the repair **Concerns:** - Recent complaint — a June 2026 review called service, billing and attitude poor ## Claims & citations Every claim below is backed by real evidence rows — uncited claims are dropped in code before publication. - BBB gives an A+ grade and lists 30 years in business, with no complaints or reviews on file _(confidence: high)_ - [Better Business Bureau](https://www.bbb.org/us/ma/east-boston/profile/heating-contractors/jm-mechanical-services-inc-0021-75973) — “This is the unaccredited BBB profile for J.M.
