Dunham and sons.did an amazing job putting in 2 mini splits.
Matt and his crew were very professional. The job was extremely well done. They went above and beyond with their service. I don't believe I have ever had anyone come and do work better.
The estimate was also very good. You can't go wrong with this team.

We recently had ductless heat pumps installed with Dunham and Sons. I cannot say enough good things about them.
They communicated well, did great work and offered a reasonable price. Also, they are nice, hard-working, and straightforward.
Jim was our initial point of contact. I would say that I knew just enough “to get myself in trouble,” and Jim’s frank but polite advice was an immense help. I lost track of how many formal quotes he provided, but it must have been around a half dozen. This is all to say that Jim is sharp, infinitely patient, and an excellent listener.

We have a Cape house with low ceilings and very little interstitial space — finding a design that preserved the form and function of our house while heating/cooling it comfortably and efficiently wasn’t simple. Ultimately, we were able to triangulate to a design that worked for our requirements and constraints. We settled on a plan using mostly ceiling cassettes to preserve space and improve aesthetics.
Matt and Jim's plan ensured that the line sets were either hidden or integrated seamlessly and there was no loss of storage or functional space in or around our home. I wasn’t sure it would be possible, but they made it work — Matt is a freakin’ wizard, or at the very least, he’s a talented guy who knows his trade. :)
When the time came to install the heat pumps, Matt, Jim and their crew (good guys, but I didn’t catch their names) did efficient, tidy work all while our kitten tried her damnedest to get underfoot. They were conscientious, leaving our home in order at the end of each day. They finished in six total days.
I should add that their price was similar to the most competitive we were quoted. (I think it was actually the best, but because the iteration we went with wasn’t directly quoted by another contractor, I can’t say that definitively.)
One final point: My partner is a woman who works in a STEM field. Her experience of men in her profession and the trades has been mixed. Everyone we encountered from Dunham & Sons treated her like just another thoughtful, intelligent person. That is to say, with respect. I admire the way they comport themselves — good eggs, every one of them.
To sum up, Matt, Jim and their crew were awesome from the moment we met them and since. They communicated well, designed thoughtfully and did meticulous work. I recommend them enthusiastically and without reservation.

I hired Dunham and Sons to upgrade my panel and other electrical work at my home. They gave me a reasonable price and scheduled the work quickly. When they arrived they worked efficiently and finished the job faster than I expected. I highly recommend this company for all of your electrical needs.
