New England Heat Pump Co.

New England Heat Pump Co. works out of Arlington and does one thing: Mitsubishi ductless heat pumps — installation, maintenance and repair for homes and small commercial spaces across Massachusetts and southern New Hampshire. The company describes itself as locally owned and family-operated with about 20 years in the trade and says it is a Mitsubishi Diamond Contractor, factory-trained to the manufacturer's installation standard. Customers write about Jimmy, the owner, more than about the company. A homeowner in July 2026 said he and his team advised on and installed a mini-split system that also needed an electric panel upgrade, gave an honest quote and handled the rebate paperwork. Another that month reported an old failing heat pump replaced in a single day plus about an hour of electrical work. A May 2026 customer had three wall units installed in one day, including a third-floor attic room with no windows. What comes up again and again is the design conversation before the install: options walked through room by room, mid-job layout changes accommodated, and Mass Save rebates navigated as part of the service. A January 2026 customer put it in the context of shopping around in Somerville — four quotes, wildly different, some with hard sales tactics — and said this company designed to their needs and budget instead of upselling. A Reddit market-research post from June 2025 that ranked Boston-area heat pump installers described the firm as a small shop of four people and a good option for anyone choosing Mitsubishi ductless. Two things to weigh. The review record is young: all 42 accounts on file date from 2025 and 2026, and every one is five stars, so there is no published example of how the company handles a job that goes wrong. And the Massachusetts Home Improvement Contractor registration number the site publishes (HIC #218773) is the company's own claim here — we have not verified it against the state registry, so check it yourself before signing. They are a natural fit for a Mitsubishi ductless or whole-home heat pump conversion where you want the owner involved in the design and the rebate paperwork handled. If your project is ducted or needs another equipment brand, ask first — the practice is deliberately narrow.
