JamesWu HVAC and plumbing

James Wu HVAC And Plumbing is a one-person, owner-operated shop in Quincy that James Wu has run since incorporating in June 2022, focused on heat pump, mini-split, furnace, boiler and central AC installs across Quincy, Boston and the South Shore, with some plumbing work on the side. The thing that stands out immediately is the volume and consistency of the praise: 34 Google reviews, every one of them 5 stars, running from spring 2025 through mid-2026. The same details recur across dozens of them — James shows up on time, explains the system and the options before he starts, and leaves the job site clean. One customer described a three-day Fujitsu mini-split job finished ‘professionally conducted, clean and efficient’; another said James measured the house personally and walked through Mitsubishi versus Bosch options before a four-person crew finished the swap in a single day. Several reviewers specifically call out that James does the work himself rather than sending a crew coordinated by a separate salesperson, and more than one mentions him helping file for Mass Save rebates on their behalf — his site has its own section for the program. A couple of reviews describe him responding to an emergency the same day: one customer’s 25-year-old furnace died in a February cold snap and James got a new one in within days; another needed an aging furnace fixed in a leased property and he was out within a few hours of the call. On the paperwork side, BuildZoom’s permit records show three 2025 jobs — a $32,000 eight-head ductless mini-split install in Braintree, an $18,000 sheet-metal HVAC job in Belmont, and a smaller $2,000 gas furnace swap in Chestnut Hill — and lists a Massachusetts Plumbing Business license (#5021) for the company, though BuildZoom itself flags that license as unverified rather than confirmed. His BBB profile carries an A+ grade with no complaints, though the profile isn’t BBB-accredited. Worth asking about: the plumbing side of the business appears secondary to the HVAC work and rests on a license BuildZoom hasn’t independently verified, so it’s worth confirming directly for any plumbing-specific job. The website also states 10 years in business, which sits ahead of the 2022 LLC incorporation date on file with BBB — worth a quick question if longevity matters to you. For a heat pump, mini-split or furnace installation in the Quincy/Boston area, this is a small, hands-on operation with an unusually deep and consistent review record behind it.
