One name turns up in review after review: Andrey. Across 110 Google ratings averaging 4.9 and 171 on Thumbtack at 4.8, customers keep telling the same story — they called, and someone came, usually that day or the next. Green Flow Solution works out of Newton and takes the heating and cooling jobs that cannot wait. A Newton homeowner writing in July 2026 described Andrey arriving well into the evening during a 100-degree stretch and having the air conditioner running within the hour. In September 2025 a customer whose furnace was leaking from a clogged drain line said the fix took fifteen minutes, at a price they contrasted with shops that bill a one-hour minimum. A property manager, writing in January 2026, put it plainly: no-heat emergencies usually get handled same day or next. The bigger installs show up too. An April 2026 review describes Andrey, Andrei and Yuri replacing two complete HVAC systems and repairing ductwork, punctual and neat about it. A May 2026 customer picked them for two high-efficiency heat pumps on the second-lowest of several quotes, and an April 2026 A/C replacement came in thousands below two other bids. Water heaters recur throughout — a tankless unit throwing an E110 code diagnosed and fixed inside half an hour in January 2026, a leaking heater replaced same-day that February. The complaints follow a pattern, and it is not about the repair itself. In July 2026 a customer with a Navien water heater said the manufacturer denied the warranty because the technician had not called its support line from the house, and that roughly two weeks of chasing followed. Days earlier, another customer said two paid service calls to quote a mini-split repair produced only a $2,000–$2,500 range by text, which they were later told was not official. Back in August 2025, a customer reported a no-show on the first scheduled day and a two-hour late arrival on the second. Even a positive July 2026 reviewer wanted employee badges and marked vehicles. So: fast and fairly priced on the call-now repair, looser on paperwork and follow-up. If the heat or the AC is out today, this is the kind of shop that picks up. If your job runs through a manufacturer's warranty, a written quote, or a multi-day install, settle in writing — before anyone starts — who calls the manufacturer, what the quote covers, and how the invoice will be itemized.
Andrey is the best! Was extremely helpful and generous with his time trying to find parking since parking spots are hard to find in my neighborhood. Thank you very much Andrey!
Called this company to look at our Navien water heater. Tech came and diagnosed it as a failed heat exchanger, but navien denied the warranty because the tech hadn’t called their support line to diagnose it properly while they were here. We have spent the last ~two weeks trying to get updates and trying to get them to follow the correct steps that navien sounds like they want for it to be a warranty claim, but they haven’t been proactive at all and it’s unclear when it will be resolved.
Extremely poor customer service and dishonest practices. I paid for two service calls to evaluate my mini-split system for repair. This was just to get a quote for repair. I received one text message from stating $2k to $2.5k. I later was told this was not official. I have repeatedly called back to get status updates on a formal quote for repair. I have been given multiple excuses, always 'tomorrow they will try'. Very unprofessional and with no regard for the customer. Could have no bid the job and not charged for visiting.
Green Flow Solutions came out promptly to give me an estimate, and after reviewing 5 other companies, not only were they the most reasonable, they turned out to be the most reliable. Other HVAC installers had me waiting on average 3 1/2 weeks. But Andrey came with his technician within days and worked thru a heatwave to restore the AC with the brand that I wanted, Carrier. I would just like to add a plug for all the folks who left positive reviews for Green Flow Solutions in the past. I would never have found such a reliable, professional team without those reviews. Thank you!
Work was efficient and service was polite. Only suggestion for improvement would be employee badge/uniform and vehicle company markings.
