Sinclaire Home Services

Sinclaire Home Services has been running out of Walpole since 1948, and by its own account is still run by the family that started it — founded by Robert Sinclaire, now three generations in. Today the company covers HVAC, plumbing, electrical and heating-oil work across dozens of towns in eastern Massachusetts, from Ashland to Framingham to Foxborough. The story that repeats across its review history is speed on the worst days. A Central Air unit that quit on a Sunday was diagnosed and back up before noon the next day. When another customer's AC failed two days before the Fourth of July, the same-day call led to same-day repair, with technician Josh walking them through it. Reviewers name their technicians often — Frank, Arthur, John, Zach and Dave among them — and describe the same pattern: an explanation of the problem before work starts, and options rather than a single take-it-or-leave-it fix. Google shows a 4.9-star average across 697 ratings, and the Better Business Bureau lists the company as A+ accredited. One January 2026 review is a clear outlier: a customer asking for a faucet-installation estimate says they were told it was free, then quoted $850 to $1,300 for the work and felt misled, eventually having it done elsewhere for $250. A separate customer who had AC and furnace work done the same day says the crew was upfront that Sinclaire "would not be the cheapest option around" — worth keeping in mind and asking for a firm, itemized quote before signing off on a larger job. The company's website also lists a Massachusetts Master Plumber license number, though that number itself hasn't been checked against the state registry. For an HVAC or plumbing call in the Walpole area, the record here is deep and consistently positive — worth calling for anything from a dead AC unit to a boiler on the fritz, with the one pricing dispute a reason to get the cost in writing upfront.
