## The honest read

Dunham & Sons is the kind of electrical contractor customers call for work that has to be tidy, explained clearly, and finished on schedule. Based in Woburn, the company says it is locally owned and operated and has 16 years in business; Massachusetts records show electrician license 21942 is active with Matthew K. Dunham as holder of record. Its work spans residential and commercial electrical service plus ductless HVAC, with a stated service area across Woburn and nearby communities.

Recent Google reviews repeatedly describe panel upgrades, mini-split and heat-pump installations, EV charging, lighting, generators, and repairs. Customers mention prompt communication, clean cable runs, careful cleanup, and detailed explanations; one May 2026 review describes a 26KW standby generator, surge protector, and ChargePoint EV charger, while other recent homeowners describe three bedroom mini-splits and a Mass Save rebate handled through installation. Google lists 4.9 stars from 57 ratings, and the written reviews are overwhelmingly positive.

There is one clear counterexample: a November 2025 reviewer said the company promised it could do a job, then stopped responding. That complaint is specific enough to ask about scope confirmation and communication if a project changes. The BBB page gives Dunham & Sons an A+ grade but says it is not accredited.

Dunham & Sons looks well suited to homeowners seeking an electrician for upgrades, charging, lighting, generators, or ductless comfort work. Before booking, confirm the exact scope, scheduling expectations, and which license holder will supervise the work.

**Strengths:**
- Clear communication — reviewers repeatedly cite prompt answers and explanations
- Clean installations — customers mention tidy cable runs and careful cleanup
- Broad electrical work — panels, EV chargers, generators, lighting, and repairs
- Ductless expertise — recent homeowners describe successful mini-split installations

**Concerns:**
- Scope confirmation — one reviewer reported a promised job was not completed
- Accreditation status — BBB lists the company as not accredited
