# JamesWu HVAC and plumbing **Trade:** HVAC / Heating & Cooling · **Address:** 9 Hodges Ct, Quincy, MA 02171, USA · **Phone:** (781) 588-3959 · **Website:** http://jameswuhvac.com/ · **Languages:** English **Rating: 4.5/5** (medium confidence) — from 34 reviews across 4 sources. A 0–5 star rating built from what customers and the public say (every review and mention weighted by where it was posted, how old, how detailed and how credible it is, shrunk toward a 3.5★ baseline when evidence is thin) plus what the record shows (Reddit recommendations or warnings, a registry-verified licence, how recently they were reviewed, customer work photos, BBB grade, negative news, a revoked licence). Positive record counts only as far as the reviews have earned it; penalties count in full. Confidence describes how much weighted evidence stands behind the number, never the number itself: low when fewer than about five normal reviews' worth of weight (or mentions only) support it, medium up to about twenty, high beyond that across at least two sources. An operator flag for a suspicious review pattern caps a rating at 3.5★ and marks it low. 100% of sentiment-scored reviews read net-positive. Last 6 months: 11 reviews, 0 negative. ## The honest read James Wu HVAC and Plumbing is a one-man-at-the-center operation in Quincy — James Wu, who the company says has run it about 10 years, does the diagnosis and installation work himself rather than handing a sold job off to installers he's never met. In a December 2025 review, a customer specifically called out liking that 'James was the one actually doing the work instead of having a salesman set it up' — and that his price beat the bigger South Shore companies. That hands-on approach shows up most clearly on emergency calls. A March 2026 review describes James reaching a leased-property furnace emergency within a few hours of a desperate call and having a repair plan the same day. Another March 2026 review describes a 22-year-old furnace dying during a storm at 9pm — James called back within 10 minutes of a message left on his site and had a new two-stage furnace installed by that Friday. In a March 2025 review, a customer said James came in on a Saturday to check a heater and returned Sunday to install a new furnace despite being fully booked the following week — and diagnosed that the old unit had failed after only 9 years because of incorrectly sized ductwork. Several reviews describe James catching problems other installers might paper over: a May 2026 review says he found undersized wiring on 15-year-old splits being replaced and rewired them properly, mentioning it only after the job was done; a July 2025 review says his team removed old parts and pipes entirely rather than reusing components that no longer fit the new system. He's also repeatedly credited with walking customers through Mass Save rebate paperwork, and an April 2026 review describes him replacing a backdraft-prone water heater the same day as a heat pump installation. The written record is entirely five-star across 34 reviews spanning 2025 to 2026, with 13 of them in just the last six months — for a furnace, heat pump, mini-split or plumbing job around Quincy and the South Shore, this is a case where the reviews consistently describe the owner as the one actually on the ladder. **Strengths:** - Owner-operator — James does the diagnosis and install himself - Fast emergency response — same-day fixes for dead furnaces - Catches hidden issues — found and fixed undersized wiring unprompted - Rebate help — walks customers through Mass Save paperwork ## Claims & citations Every claim below is backed by real evidence rows — uncited claims are dropped in code before publication. - In a December 2025 review, a customer said James does the installation work himself rather than handing it to a salesman-arranged crew, and that his price beat bigger South Shore companies _(confidence: high)_ - [Google Reviews](https://www.google.com/maps/reviews/data=!4m8!14m7!1m6!2m5!1sCi9DQUlRQUNvZENodHljRjlvT2xscWNUVkRVVXRZYWtOUmRVNVRibEprV0c1eFVGRRAB!2m1!1s0x0:0x4a46fa759a9dedd6!3m1!1s2@1:CAIQACodChtycF9oOllqcTVDUUtYakNRdU5TblJkWG5xUFE%7C%7C?hl=en) — “5★ James did an excellent job, His team was fast and went above what was asked.
