Heat Pump Installation in Concord, MA 01742

“We had a great experience working with Basnett Plumbing Heating & AC to install heat pumps / mini-splits in our home and in-law apartment. Their staff helped us choose the correct equipment for our complicated situation via email and phone and then handled all the paperwork required for us to get an energy efficiency rebate from the town. When Zach and the rest of the team came to install, they made great suggestions for equipment placement for best performance, appearance, and maintenance, and to minimize cost. The team was extremely professional, neat, efficient, explained everything carefully to us, and was just lovely to work with. Everyone was also careful to follow the COVID-19 protocols. Can’t recommend these guys enough!”
