# William F. Lynch Co., Inc. **Trade:** HVAC / Heating & Cooling · **Address:** 50 Millbrook St, Worcester, MA 01606 · **Phone:** (508) 756-5705 · **Website:** http://www.wflynchinc.com/ · **Languages:** English **Rating: 3.2/5** (low confidence) — from 1 reviews across 6 sources. ## The honest read William F. Lynch Co., Inc. is a Worcester-based mechanical contractor that says it has more than 90 years of experience and is family-owned and operated. Its stated work includes design-build mechanical systems, plumbing and pipefitting, HVAC, sheet-metal fabrication and installation, repairs, maintenance, and 24-hour emergency service across Central Massachusetts and beyond. The company’s public profile also lists plumbing, gas and piping, boiler and water-heater, septic-system, and sheet-metal work. A Massachusetts registry check identifies William F Lynch Co Inc as the active holder of an HVAC license, while BuildZoom reports a Sheet Metal Business license and three other Massachusetts licenses. BuildZoom shows 17 projects, although its project list is not a customer-review history. The written customer history is limited and dated. In a May 2020 Google review, a customer called the company an excellent mechanical company and praised its service and staff integrity. Google’s visible rating is 5 stars from three ratings, but the single quoted written review is not enough to establish a broad or recent pattern. William F. Lynch is a reasonable fit for commercial, institutional, healthcare, educational, and industrial mechanical work described on its own site, as well as plumbing and HVAC needs. Before booking, confirm the exact trade license and scope for the proposed job, the emergency-service terms, and current availability; ask for recent references if the project is residential or outside its core institutional and commercial markets. **Strengths:** - Mechanical systems — design-build, installation, repairs, and maintenance - Emergency response — official site advertises 24-hour service - Service integrity — 2020 reviewer praised staff integrity **Concerns:** - Review depth — one written account is dated May 2020 - Project fit — confirm scope for residential or non-institutional work - License scope — verify the exact trade license for the project **Where sources disagree:** - The official site describes broad mechanical contracting services, while BuildZoom presents a narrower service list and a 17-project directory view. - Google shows 5 stars from 3 ratings, but only one dated written review was available for the synthesis. ## Claims & citations Every claim below is backed by real evidence rows — uncited claims are dropped in code before publication. - The company says it is family-owned and operated with over 90 years of experience. _(confidence: high)_ - [Official Website](http://www.wflynchinc.com) — “Company history (self-reported): over 90 years of experience” - [Official Website](http://www.wflynchinc.com) — “Ownership (self-reported): family-owned and operated” - The official site describes design-build mechanical work, plumbing and pipefitting, HVAC, sheet metal fabrication and installation, repairs, maintenance, and 24-hour emergency service. _(confidence: high)_ - [Official Website](http://www.wflynchinc.com) — “Family-owned mechanical contractor serving Central Massachusetts and beyond with design-build, plumbing/pipefitting, HVAC, sheet metal fabri…” - BuildZoom lists plumbing, gas and piping, sewer laterals, boiler and water heater, septic tanks and systems, and sheet metal services. _(confidence: medium)_ - [BuildZoom](https://www.buildzoom.com/contractor/william-f-lynch-co-inc) — “Services offered (BuildZoom): plumbing, gas and piping, sewer laterals, boiler and water heater, septic tanks and systems, sheet metal” - A Massachusetts registry check identifies an active HVAC license held by William F Lynch Co Inc. _(confidence: high)_ - [State License Registry](https://occupationallicensingandpermitting.mass.gov/madol/s/license-search-page) — “MA hvac license 434-SM-B registry-verified active — registry holder of record: William F Lynch Co Inc” - BuildZoom reports 17 projects and an active-when-checked Massachusetts license profile. _(confidence: medium)_ - [BuildZoom](https://www.buildzoom.com/contractor/william-f-lynch-co-inc) — “17 project(s) shown on BuildZoom” - [BuildZoom](https://www.buildzoom.com/contractor/william-f-lynch-co-inc) — “BuildZoom lists William F Lynch Co Inc at 50 Millbrook St, Worcester, MA, phone 508-756-5705, and reports an active-when-checked Massachuset…” - A May 2020 Google reviewer called the company excellent and praised its service and staff integrity. _(confidence: medium)_ - [Google Reviews](https://maps.google.com/?cid=16263428809681645034&g_mp=CiVnb29nbGUubWFwcy5wbGFjZXMudjEuUGxhY2VzLkdldFBsYWNlEAIYBCAA) — “5★ Excellent Mechanical company.
