Cold Climate ASHP in Cambridge

Air source heat pumps will operate under a wide range of temperatures, but the colder it is outside, the less efficient the heat pump will be. Fortunately, there are cold-climate air source heat pumps specially designed to operate efficiently at lower temperatures (even below 0 degrees Fahrenheit!) This newer technology is often installed in places with harsh winters, such as New England or the Midwest.

In Cambridge, it’s a good idea to install cold-climate air source heat pumps so you can continue using them on particularly cold days. For most homes, it will also be a good idea to have a backup source of heat. Many homeowners choose to keep their existing furnace or boiler for this purpose.
