HomeWorks Energy

HomeWorks Energy runs on the Mass Save program: crews show up to blow in attic and wall insulation, seal air leaks, and price out heat pumps and HVAC upgrades, mostly through the state's subsidized energy-assessment pipeline. The company is based in Charlestown and carries an active Massachusetts HVAC/sheet-metal license (961-SM-B). The volume behind that reputation is hard to ignore — 4.7 stars across 2,667 Google ratings, part of a broader run of 908 reviews since 2024 across five sources, and a Better Business Bureau A+ rating. In the past several weeks alone, named crews (Bobby and Chris, Angel and Dreilin, Kevin and Caesar, Nathan's team, and dozens more) show up in review after review for showing up on time, walking homeowners through the insulation or air-sealing work before starting, and leaving attics, basements, and garages clean when they're done. Energy assessments get singled out too, with reviewers describing the audit itself as thorough and the resulting estimate as fairly priced. It isn't spotless. One recent reviewer says a scheduled appointment was a no-show with no call, costing them a day off work. A more pointed complaint describes a heat-pump sales rep who pushed a Gree unit while claiming it matched Mitsubishi quality, only for the customer to later learn Gree was the cheaper brand HomeWorks actually stocked. Another describes a multi-year Mass Save grant project that stalled after early approvals, with a customer-service team the reviewer called unresponsive. These are outliers — 4 negative reviews among 294 in the last six months — but worth raising directly if the job involves equipment sales or a grant-funded project rather than a straightforward insulation job. For a no-cost energy assessment or an insulation and air-sealing job through Mass Save, the recent reviews back up booking them. For a heat pump purchase or anything routed through a multi-step grant, get the equipment brand and project timeline confirmed in writing before signing.
