Heat pumps

Heat pumps provide heating and cooling in a single device so you can maintain a comfortable temperature all year round. Ductless versions are convenient to install, as they don’t require ductwork inside walls. And their energy-efficient operation provides a cost-effective solution for temperature control.

Massachusetts residents can make these devices even more affordable with the rebates provided by the Sponsors of Mass Save.
