Heat Pumps Unlimited

Heat Pumps Unlimited runs out of 110 Pembroke St in Kingston, and the work it gets called for is right there in the name: ductless mini-splits and heat pumps, put in, cleaned, and kept running. It holds an active Massachusetts sheet-metal licence, 863-SM-B, verified against the state registry with Heat Pumps Unlimited Inc. as the holder of record, and the Better Business Bureau grades it A+. The written record behind it is deep rather than decorative: 4.9 stars across 159 Google ratings, and 119 reviews on file running from 2021 to the present. What homeowners bring up first is time. A customer whose two mini-splits were serviced on a noon-to-two window wrote that the crew "were here promptly at 12"; another said the team "showed up on time" each day of an install and finished earlier than expected. Installation is the clearest strength. Customers describe complete mini-split installs where the plumbing and electrical were "done exactly the way that I wanted" — that one from a November 2025 review of a two-unit Fujitsu job — and repeat callers note the equipment holding up years later. The office is named as often as the technicians: Dawn, in particular, turns up again and again for scheduling, phone diagnosis, and chasing down parts. In a December 2025 account, a family four days into a no-heat Christmas said she found a sensor their regular repair tech had told them would take another week to ship. Price shows up as a favorable comparison more than once. In a June 2026 review, a homeowner who had been quoted over $4,500 by another company wrote that the same problem was diagnosed and fixed in an hour for under $400: "I will never call anyone else." They also do electrical alongside the HVAC — panel work tied to an install, and in one long-running customer's telling, all of their electrical needs for several years. The one thing to raise before booking is refrigerant-leak diagnosis. A June 2025 reviewer described being told there was no leak, having refrigerant added that did not hold, then paying another $150 on a return visit to be told there was a leak after all, with the repair itself requiring further appointments. It is a single detailed complaint against a long and otherwise consistent run, but it is specific enough to be worth a direct question about how leak testing and repeat visits are scoped and billed. For South Shore homeowners putting in mini-splits or ductless heat pumps — especially Mass Save work, which the company advertises — this is a well-established, licensed choice with a long service history behind the install. Confirm the licence is current for your job type and get the diagnostic-versus-repair billing in writing up front.
