Central Air Conditioners

Before upgrading or installing a central air conditioner, consider a central heat pump. Central heat pumps work with your existing ductwork to keep your home cool during the summer, but unlike a central air conditioner, these systems can also work in reverse during the winter to keep you warm. Compared to heating with oil, propane, or electric baseboard, a heat pump is the lowest cost fuel source. The Sponsors of Mass Save® offer rebates up to $1,250 per ton. Click here to learn more.
