The City of Cambridge has partnered with Abode to help residents transition to clean heating technologies

Cambridge Clean Heat is a city-wide initiative providing educational resources and a marketplace of third-party vetted contractors, empowering residents to adopt clean heating and cooling technologies with confidence.

Air source heat pumps and solar hot water systems are cost-effective, market-ready technologies that transform how homes use energy. These technologies can help save you money on your utility bills and also significantly help Cambridge decrease its overall carbon footprint, benefiting the community.

Cambridge Clean Heat is working with Abode to connect residents with local, reputable contractors. Through this program you can request, receive, and compare quotes from multiple contractors to ensure the system you select will meet your goals and operate efficiently.

Air source heat pumps (ductless mini-splits) are a clean technology you can use to both heat and cool your home. There are a number of economic, environmental and health benefits associated with installing air source heat pumps. Learn all about this technology and whether it’s the right option for you.


Two primary technologies exist for heating a home’s water supply with electricity. Even during cold winter days, these technologies can help you save on water heating costs and decrease your carbon footprint.  Through many incentives these technologies are more affordable than ever, and are the most environmental way to heat your water.

Why Clean Heating and Cooling?

Environmentally Friendly

Clean heating technologies tied to the MA electric grid produce 40-60% less carbon emissions than traditional fossil fuel based systems. 

Economic Benefits

Massachusetts leads the nation in energy efficiency, which includes making these systems more cost effective to run and ensuring the installation is comparable to traditional systems.

Health and Wellness

Whether carbon monoxide in our home, or carbon dioxide in our atmosphere, the writing is on the wall– a world without burning fossil fuels is where we must go.


Properly sized clean heating technologies can radically improve your home’s temperature and humidity all year long.  Keep you cozy and your house healthy.

Incentives for Clean Heating and Cooling

Mass Save HEAT Loan

If you’re installing a solar hot water system or air source heat pumps, you may be eligible for a 0% interest HEAT Loan from Mass Save. You can finance up to $25,000 over the course of 7 years for home energy efficiency upgrades.  While fuel prices fluctuate for many projects the energy savings can often come close with covering the principle payments each month. Find out more about Mass Save’s HEAT Loan program. 


Solar hot water and air source heat pump systems installations in Massachusetts qualify for the Alternative Energy Certificate (AEC) program. With this program, non-emitting renewable technologies generate certificates based on their energy production. These certificates are sellable to utility companies looking to meet state-mandated renewable energy goals. The revenue earned from these certificates will help you to further save on your solar hot water or air source heat pump installation.  Learn more about AECs here.

Rebates & Tax Credits

Massachusetts leads the nation in energy efficiency and has many incentives and rebates available to help make clean heating technologies affordable. Learn more about rebates available from Mass Save, or through the MassCEC. Mass Save heat pump rebates have increased starting in 2022, and eligible air source heat pump equipment could qualify for a rebate of up to $10,000.
