Take It From Our Customers

Heat Pump Installation in Concord, MA 01742

“Everyone from Basnett who worked in my house was professional, thorough, and helpful. At the beginning, there was a question about how the switch from the heat pump to the backup heating would happen to accommodate the multiple zones in my house. Zach was determined to find a solution with the smallest chance for problems that would be easy. He did come up with one that is working well and he spent time helping me understand how to use it.”
- Marlene M.
