Nascimento HVAC & Plumbing Inc

Nascimento HVAC & Plumbing is a Newton outfit built around its owner — reviewers call him Klay, Clay, or Klayton, and he shows up in the reviews personally: on a Saturday night for a heating emergency, the same day for a leaky kitchen sink before Christmas, walking a family through permit requirements mid-remodel so they wouldn't run into trouble with the city. The reviews that go deep describe a company that competes hard on price without cutting corners. One customer got quotes from three companies before choosing Nascimento for a boiler replacement, and cited responsive communication and a timeline they actually kept. Another, replacing a gas dryer line, described a quote that beat the nearest competitor "by a mile" and extra safety features added at no charge because, in the owner's words, "if we're here, we do it the right way." The work spans both trades — furnace and boiler replacements, central AC swaps, mini-split cleanings, water heater emergencies, and plumbing repairs — and several customers describe using the company more than once. Two reviews break from that pattern. In an April 2026 review, a customer described running what they called a routine test — disconnecting a wire on a new home's system — and said Nascimento diagnosed it as needing a full replacement rather than the simple fix it was. A shorter 2025 review calls the company simply "untruthful." Both are outliers against a long run of five-star write-ups, but they specifically challenge honesty rather than just workmanship, which makes them worth asking about directly. The Better Business Bureau rates the company A+, and its page lists a Massachusetts plumbing license (#34463) and sheet metal license (#18369) — BBB's own listing, not something verified against the state registry. For anyone in the Newton area needing HVAC or plumbing work, the record here is mostly a company that shows up fast and prices fairly, with two dishonesty complaints worth weighing before booking.
