Cardigan Mechanical is an HVAC company that says on its own website it was formed to serve the Mascoma Valley, and it offers free estimates and 24/7 emergency service. The company holds an active New Hampshire HVAC licence, number MBE2101349, on the state registry. In October 2026, a Google customer said the team guided them to the right replacement heating system and left the workspace neat and clean. In August 2026, a Google customer said Mike Harris installed a heat pump and mini-splits in a two-hundred year old farmhouse, working with a master carpenter to hide the conduits. In September 2026, a Google customer said the crew installed new mini-split equipment and diagnosed issues with their existing equipment. In 2025, a Google customer said the company installed a six zone gas fired boiler in their old farmhouse on time and on budget.
Very professional, friendly installers.
Highly recommend this company for anyone needing a replacement heating system. From start to finish, the team was professional and extremely knowledgeable, taking the time to answer all of our questions and guide us to the right system. The entire installation process was incredibly smooth, and they left the workspace neat and clean. Truly top-tier service! Thank you Mike and Phil
We had mini splits installed recently by Cardigan Mechanical and had a great experience. Good price, great work, and fast communication. Would highly recommend!
The entire crew at Cardigan Mechanical provided excellent service for our Mini split heat pumps system, including installing new equipment at our house and diagnosing issues with existing equipment. I highly recommend Cardigan Mechanical.
Mike Harris and his team are wonderful, hard working, and really smart. You can't go wrong! Great service and they keep their promises.
