Air Source Heat Pumps

Install a high-efficiency air source heat pump—and start saving.

Air source heat pumps can cut your heating and cooling costs by up to 30 percent.

Air source heat pumps extract heat from the air outside and distribute it inside your business. During warmer months, this process is reversed to provide cooling.

There are both ducted and ductless heat pumps, making them suited to buildings with or without existing ductwork.

The Sponsors of Mass Save also offer incentives for qualifying integrated controls, which allow you to control a heat pump and a central heating system from a single device.
