Cox's Old Colony HVAC & Plumbing

Cox's Old Colony HVAC & Plumbing is a Hanover shop built around one name that shows up in nearly every review: Bill (Bill Flannery), the owner, who answers his own phone and often shows up personally for emergency heat and AC calls. The pattern holds across years of jobs — furnace and boiler replacements, central AC repairs and installs, and plumbing work like water heaters, toilets and faucets — for both homeowners and small businesses. The through-line is speed on emergencies. When a furnace quit on a Sunday, Bill was the only company that picked up that night and had a crew out at 7am Monday with heat restored the same day. A boiler failure in the dead of winter got a next-day visit and a full replacement within two days. When a customer's AC failed at her mother's house, Bill ordered parts, had them delivered that afternoon, and had the house cool again by 11am the next day. Several long-term customers — one for over 10 years, another running a restaurant for 8 — describe the same responsiveness on repeat, reasonably-priced jobs. Pricing gets called out as competitive and flexible more than once: one customer got the best of three bids, another was worked into a strict budget, and a third said Bill's quote was far more reasonable than a competitor's. Three older reviews complicate that picture. In 2021, a customer says two technicians spent ten minutes looking at a malfunctioning boiler before quoting an $8,000 replacement — a second company fixed it, in about the same visit length, a few hours later. In 2023, a reviewer describes a $180 diagnostic visit that recommended a $4,500 furnace replacement when a $300 blower motor turned out to be the actual fix, plus a technician who arrived four hours late with no call. A 2022 review separately describes rude, cursing phone conduct. All three predate the long run of positive 2024–2026 reviews, but they're worth knowing about before agreeing to a big-ticket replacement. The Better Business Bureau grades the company A+, and it holds a 4.3★ Google rating from 98 reviews. For routine heating, cooling or plumbing calls, the record backs up the responsiveness; for a large replacement recommendation, it's reasonable to ask what specific part failed before signing off.
