A and C Mechanical LLC is a Merrimack, New Hampshire HVAC company whose NH Mechanical Business Entity licence MBE2001301 is listed as active by the state registry, with A And C Mechanical, LLC as the holder of record. The Better Business Bureau matches the company to 23 Fairway Drive in Merrimack, gives it an A+ rating, and says it has six years in business; the profile is not accredited. Homeowners repeatedly describe A and C as responsive, careful, and clear about the work. The 42-review Google record runs from 2022 through 2026, with 34 reviews in the last six months and a 5.0 average from 46 ratings. Reviews describe furnace and central-air replacements, heat-pump and Mitsubishi mini-split installations, annual maintenance, emergency furnace and air-conditioning repairs, gas-line work, boilers, pool heaters, and a whole-house generator. Reviewers commonly mention prompt emergency response, clean installations, explanations homeowners could understand, fair pricing, permits and inspections, and follow-up after the job. Before booking, confirm the exact scope and licensing coverage for any project that combines HVAC with plumbing, electrical, or generator work. The BBB profile describes the business's services as plumbing and heating, while the customer record also describes cooling, gas, and generator work; those accounts are customer reports rather than a complete service catalogue. Ask which portions A and C will perform directly, who handles any required electrical work, and what maintenance or warranty follow-up is included. They look like a strong fit for New Hampshire homeowners seeking heating and cooling installation, repair, or maintenance, especially projects needing careful system selection and clean commissioning. Confirm equipment availability, permits, project timing, and the specific licence or trade professional attached to the job before signing.
