**Rating: 4.4/5** (high confidence) — from 75 reviews across 5 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.
92% of sentiment-scored reviews read net-positive. Last 6 months: 7 reviews, 0 negative.

## The honest read

Accutemp Engineering is a Stoneham, MA HVAC contractor with an active, state-verified Massachusetts HVAC license. Reviewers name a large team over the years — Sean, Damon, Manny, Miguel, Tom, Jamie, Boris, Marvin, Tommy, Joe, Troy, and Matt among others.

Customers describe detailed, specific work: installing four wall-mounted mini-split units, replacing a furnace after comparing 16 quotes, tracking down a decade-old installation defect that a previous company had left behind, and returning roughly half a dozen times at their own cost to resolve a manufacturer defect in a boiler unit — without complaint, despite losing money on it. Several reviewers describe emergency response — a Sunday no-heat call with children in the house fixed the same evening, and a technician dispatched mid-snowstorm. On at least one job, a technician recommended a smaller, correctly sized unit rather than the larger one first quoted.

A handful of older reviews, mostly from 2020–2022, describe more serious problems: one 2022 review says a repair accidentally broke the customer's AC, left them without cooling for three months, and the company then wanted thousands more to fix it rather than honoring warranty coverage; other reviews from that period mention billing confusion, technician turnover, an equipment downgrade the customer felt was a bait-and-switch, and an undisclosed $50 service fee. None of these complaints appear in the company's 2023–2026 record, which has been uniformly positive.

For HVAC installs, repairs, or maintenance in the Stoneham/Newton area, Accutemp's licensed status and detailed recent track record are reassuring — worth getting pricing and warranty terms in writing given the handful of older complaints on that front.

**Strengths:**
- Warranty persistence — returned about six times to fix a manufacturer defect
- Honest sizing — recommended a smaller unit than first quoted
- Emergency response — fixed a no-heat call the same evening

**Concerns:**
- Serious 2022 complaint — a repair broke the AC without a warranty fix
- Billing complaints — turnover and communication issues cited in 2020-2022
