Green Flow Solution Inc

Green Flow Solution Inc is a Newton HVAC outfit built around one recurring promise reviewers keep confirming: they show up fast and fix it right the first time. Google puts them at 4.9★ across 110 ratings, and the pattern repeats everywhere else — 4.8★ from 171 Thumbtack ratings, 5.0★ on both HomeAdvisor and Angi. The technician named most often, Andrey, comes up again and again for diagnosing a problem within minutes of arriving and for turning down the upsell — several reviewers specifically call out that he recommended the cheaper fix over a costlier replacement. The jobs described are substantial and varied: a tankless water heater thrown an E110 code diagnosed and fixed inside thirty minutes, a dead central A/C unit replaced on short notice for thousands less than two competing quotes, a full swap of two HVAC systems plus ductwork repairs, and heat-pump installations chosen after comparison-shopping five other companies. One reviewer described two other companies pushing a full replacement on a 26-year-old A/C unit that was only blowing air — Green Flow instead found and repaired a leak with a custom-fit copper pipe in under two hours. Response times mentioned across dozens of reviews run from thirty minutes to same-day, including weekend and after-hours calls during a heat wave. Two recent complaints are worth knowing about. In a July 2026 review, a customer says a technician diagnosed a Navien water heater's failed heat exchanger but hadn't called Navien's support line during the visit as the manufacturer requires, so the warranty claim was denied — the customer says two weeks of follow-up produced no resolution. Another July 2026 review describes a mini-split repair quote delivered by text ($2,000–$2,500) that the company later said wasn't official, calling the pricing process dishonest. An older complaint, from August 2025, describes a subcontracted plumber who no-showed the first day, arrived two hours late the next, then billed $620 with no itemization for under two hours of work. Green Flow is the call for a fast, same-day HVAC fix — no-heat emergencies, dead A/C units, water heater failures — and the volume of specific, detailed praise across seven platforms backs that up. For a warranty claim or a larger repair quote, ask for the manufacturer-required diagnostic steps and an itemized invoice up front.
