Sinclaire Home Services has 697 Google ratings averaging 4.9, and this summer it kept getting calls about air conditioners that quit in the heat. In July 2026, two days before the Fourth, one customer's AC stopped on one of the hottest days of the year; Josh had it working the same day. Another July 2026 customer's central air died on a Sunday, and Frank diagnosed it Monday morning, walked through the options and had it running before noon. In June 2026, Frank and Sam laid out several options for a new AC unit and installed it the same day — telling the customer plainly they would not be the cheapest, but stand behind their work. The Walpole company says it was founded by Robert Sinclaire in 1948 as a heating oil provider and is still family-owned three generations later. It now covers HVAC, plumbing, electrical and heating oil across eastern Massachusetts, from Needham and Dedham to Framingham, Franklin and Attleboro. The state registry shows Dennis Sinclaire Jr.'s Massachusetts plumber licence as active. The crews explain before they fix. In an August 2026 review, a service-plan member replacing a water heater said Dave and Vinnie gave options without upselling and pointed them to a local supply house for new faucets. A May 2026 customer had an old furnace and AC replaced and said the crew was transparent about pricing and kept them updated through the day. In a January 2022 review updated in 2026, a boiler customer said the company came out three times during a storm to keep the family warm, and that the company that serviced it before would find repairs of around $1,000 each year. In January 2026, a customer called the company over-priced scam artists: the office said there was no estimate fee, the technician said he would waive one, and the quote was $850 to install a faucet they supplied, or $1,300 with the company's faucet; they had it done elsewhere for $250. The BBB grade is A+.
“Sean was excellent. He explained to me everything he was doing and was very thorough in investigatin”
Excellent communication from the team. They arrived quickly, diagnosed the issue, and had the part on hand. Great service!
Andrew & Zach were great they explained everything from start to finish and were happy to answer any questions I had. They cleaned up and were very respectful.
*Great* customer service! Had an annual plumbing check-up, no-charge since we're "Diamond Members." Wouldn't usually pay extra for that privilege, but they made it seem reasonable when I replaced. my hot water heater. Got clear answers on questions that I didn't want to pay $$$ to fix; didn't try to up-sell, just gave me options. Dave and Vinnie took time to sit down, talk, and patiently answer m y questions. I did want to replace my bathroom vanity faucets. The guys helpfully directed me to local plumbing supply, and it was super easy to call back and greenlight the reasonable estimate. Dave & Vinnie came back and did a great job. Local mom-and-pop feel but with the heft of a professional team. Thank you!
We always have a great experience with Sinclaire! Today's job was no different. Dave explained everything thoroughly and labeled all the parts to make it easy to understand. 🙂 Highly recommend Sinclaire!
I needed my tankless water heater served in a hurry for a home inspection. Mike (I think) and Vinnie were thoughtful, cooperative and prompt. They went above and beyond.
