This market assessment focuses on the adoption of air-source heat pumps (ASHPs) in the residential HVAC sector across the Northeastern U.S. From 2013 to 2021, ASHP sales grew 250% across New England and New York. The report analyzes barriers to adoption—including installer training gaps and supply chain issues—while highlighting opportunities through interviews with manufacturers, distributors, contractors, and end users. It reviews incentive programs and concludes that while challenges remain, the Northeast is making significant progress toward transitioning to high-performance HVAC systems.
