Its website quotes a customer who was happy with the installation of a new furnace and oil tank, and lists a service area of Portland, Brunswick, Windham and Auburn. In a 2026 review, a customer said they dealt with a number of people who listened carefully to what they wanted and explained the pros and cons of the options. That 2026 customer said everything was completed in the agreed time frame and the bill was exactly the same as the estimates. A 2026 customer said the team arrived on time, worked efficiently and kept them informed throughout the process. In a 2026 review, a customer said they were told a September 2025 service visit would cost $299, paid $230 that day, and were then charged $299 on January 2, 2026 without notice. That 2026 customer said no one called back as promised, a summons followed, and their bank returned the January charge after a dispute. In a 2026 review, a person who said they were not a customer described a Knowles Mechanical employee entering their house uninvited at the wrong location, and said the company's response was to downplay and deflect what had occurred. The news sites whatnow.com and powerboat.news have reported that Knowles Mechanical, Inc. filed a petition alongside affiliated companies. **Strengths:** - Bill matched estimates — a 2026 customer said each item was clearly explained - On-time arrival — a 2026 customer said the team arrived on time **Concerns:** - A billing dispute — a 2026 customer said $299 was charged without notice - Wrong-house entry — a 2026 non-customer said an employee entered uninvited - A filed petition — two news sites reported it filed alongside affiliated companies ## Claims & citations Every claim below is backed by real evidence rows — uncited claims are dropped in code before publication. - 4-star Google rating from 49 ratings _(confidence: high)_ - [Google](https://www.google.com/maps/search/?api=1&query=Knowles%20Mechanical%2C%20Inc.&query_place_id=ChIJMTor429vskwRB-4H34ebfL4) — “Google: 4★ from 49 ratings” - Its website lists a service area of Portland, Brunswick, Windham and Auburn _(confidence: medium)_ - [Official Website](https://knowlesmechanical.com) — “Stated service area (self-reported): Portland, Brunswick, Windham, Auburn” - Its website quotes a customer happy with the installation of a new furnace and oil tank _(confidence: medium)_ - [Official Website](https://knowlesmechanical.com) — “About (self-reported, verbatim): “I am very happy with the installation of my new furnace and oil tank.
