Dunham & Sons is a Woburn electrical and ductless heating and cooling contractor, and a 2026 Google reviewer said Jim and the team installed 3 mini splits in the bedrooms on their second floor and also modernized several of their light fixtures. Its Massachusetts electrician licence, number 21942, is active on the state registry in the name of Matthew K Dunham. On Google it holds 4.9 stars from 57 ratings, and the Better Business Bureau gives it an A+ grade. The company's website describes ductless HVAC installation and residential and commercial electrical services in Woburn and nearby Massachusetts communities. A 2026 customer wrote that the company installed mini splits in two upstairs bedrooms in less than a day and was responsive from the quote through the submission of the Mass Save rebate. In a 2025 review, a customer with a Cape house with low ceilings said Jim provided around a half dozen formal quotes, the customer settled on a plan using mostly ceiling cassettes, and Matt and Jim's plan kept the line sets hidden or integrated. That 2025 customer said the heat pump install took six total days and the home was left in order at the end of each day. A 2025 reviewer said Matt and Jimmy completed a Kohler 26KW standby generator with an ATS switch and also installed a whole house surge protector and a ChargePoint EV charger. In a 2025 review, a customer said the company upgraded their panel, scheduled the work quickly and finished faster than expected. A 2024 reviewer said Matt helped install a whole house fan, added outlets and switches, and suggested placing the switch out of the reach of smaller children. In a 2022 review, a customer who had contacted several electricians who never showed up said Matt made room in his schedule for lights in a nursery and bedroom, and vacuumed and swept every room he worked in. A 2025 Google reviewer wrote that the company lied about being able to do the job, lied again in its response to the review, and then gave no response to texts asking why it would not do the work after saying it would.

Jim and the team at Dunham and Sons installed 3 mini splits in the bedrooms on our second floor and they did fantastic work. They keep us so cool in addition to the central AC on our first floor that wasn’t quite getting upstairs. They also modernized several of our light fixtures and it’s made a huge difference. Highly recommend!
We hired Dunham&Sons to install mini splits in two upstairs bedrooms. From the initiate quote through installation, and submission of the Mass Save rebate they were responsive, helpful, and made the entire process easy. They answered all my questions, installed both units in less than a day, and made sure it looked as neat as possible on the outside.
Jim, Matt and team are superb. They are creative and look for solutions that work for homeowners. Highly recommend these folks!
