Air Source Heat Pumps in Cambridge

Air source heat pumps are an electrical clean heating and cooling technology used to regulate air temperature in a building. With air source heat pumps, you can keep your home warm in the winter and cool in the summer. Using this technology can help save you money because the operating costs are lower than traditional home climate systems that run on gas, oil, and more. 

How air source heat pumps work


Both heats and cools your home, depending on the season and temperature.

Can either be ducted or ductless, depending on your building, its needs and your preferences.


Work well in cold climates, making it an effective heating solution for homes in New England.

Incentives for air source heat pumps


If you install air source heat pump systems in Massachusetts, you qualify for the Alternative Energy Certificate (AEC) program. With this program, non-emitting renewable technologies generate certificates based on their energy production. You can sell these certificates to utilities, helping you further decrease your overall investment for your air source heat pump installation. Learn more about AECs.

Mass Save HEAT Loan

If you're installing solar air source heat pumps, you may be elgible for a 0% interest HEAT Loan from Mass Save to finance the projects. You can finance up to $25,000 of home energy efficiency upgrades. Find out more about Mass Save's HEAT Loan.


Massachusetts has a host of incentives and rebates available to help decrease your investment for air source heat pumps. Learn more about rebates available from Mass Save, or apply for the rebates here.

Should I go with a ducted, or ductless system?

You should go with ducted if...
home with ducted air source heat pumps
  • You have existing ductwork 

  • You don't like the appearance of indoor mini splits

  • You're interested in heating your whole property, and the fewer components, the better

You should go with ductless if...
house with ductless air source heat pumps
  • You don't have existing ductwork

  • You're looking to heat and cool a smaller space

  • You want the easiest installation possible

Do you live in a multifamily building?

If you live in a multifamily, air source heat pumps are a good solution to heat and cool your home. That said, there are extra considerations to take when installing this technology on a shared property. Our no-cost Retrofit Advisor can help your apartment or condo building learn more about suitable clean heating and cooling options and help you find ways to finance your project.

Cold climate air source heat pumps 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 degress farenheit!) 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.

Air source heat pumps in action

Ducted air source heat pumps

John G. just installed a ducted air source heat pump system to heat and cool his home in Massachusetts. After taking advantage of alternative energy credits (AECs) and $550 in rebates, he's saving roughly $1,200 a year in energy costs. John's system is also paired with a rooftop solar panel system, powering the heat pumps with clean, renewable energy. His advice to people considering this technology? "Look into it!"

Mini-split installation

Seth F. installed mini-splits for his home in Massachusetts. His heat pumps, financed with a zero-interest HEAT loan, save him roughly $1,000 a year. The mini-splits are paired with solar PV system and insulation from MassSave. Best of all, the ductless heat pumps cover 100% of his heating and cooling needs: "Don't be afraid of relying on heat pumps as your sole heating system--cold climate heat pumps have plenty of power as long as your home is insulated properly."
