CARTER'S HEATING & COOLING LLC

Carter's Heating & Cooling is a family-run HVAC company in Haverhill, started by owner David Carter in 2012. It handles heating, air conditioning and water heater installation, repair and maintenance, plus boiler and furnace work, for residential and light commercial customers, with emergency service available. Reviewers describe Dave as personally involved — several accounts mention him showing up himself, including a January 2026 review where he canceled personal plans to fix a furnace after his crew was already out on other jobs, and a December 2025 review where he helped a family get a replacement furnace ordered and installed within days of the old one failing. Technicians Aaron and Adam come up repeatedly for annual maintenance visits, with reviewers noting they clean up thoroughly and explain what they're doing before they leave. One August 2025 review describes a more difficult experience: a technician, described as the owner's son, arrived two hours late to a water leak call and recommended replacing five parts the reviewer felt weren't all necessary. A separate September 2025 review, otherwise positive about a boiler cleaning, docked a star specifically over being asked for a tip on the online invoice. For routine heating and cooling service or an emergency furnace failure in the Haverhill area, most reviewers describe a responsive, hands-on family operation; if a repair estimate feels larger than expected, it's worth asking for a second opinion on which parts genuinely need replacing.
