Two Mitsubishi mini-splits brought warmth to a customer’s garage and upstairs, according to a December 2024 Google review of C&D Mechanical LLC. Other customers writing in 2024 and 2025 described split-system installations, furnace replacement, central air and plumbing repairs. The company says it is family-owned and operated, established in 2022, with more than 10 years of team experience. Its stated New Hampshire service area runs from the Lakes Region south and includes Laconia, Concord, Bow, Manchester, Nashua and Salem. Alongside residential work, it advertises light-commercial HVAC and plumbing, including boilers, rooftop equipment, water heaters and whole-home water filtration. In an April 2025 review, a plumbing customer said Chris and Derek arrived on time, explained the needed repairs and left the work area clean. Another reviewer that month praised the installation of a new split system and the cleanup afterward. An August 2024 customer described exterior-faucet pipework and replacement, followed by an inspection of the furnace and air-conditioning units and recommendations for future maintenance. The heating and cooling accounts include an August 2024 furnace replacement with central air added to a house. A separate August mini-split customer said the workers answered every question and gave a veteran discount. Another reviewer writing that month praised the price, timely work and follow-up after completion. In December 2024, a customer said Chris responded to a Facebook post after weeks of difficulty finding someone to work on the HVAC, then made the necessary repairs quickly. C&D advertises free estimates and weekday hours of 7 AM to 4 PM. Its after-hours emergency service is for existing customers.
