The regional residential heat pump market has seen significant growth in recent years. Various market influences have driven this growth, yet there remain persistent barriers to wider adoption and clear opportunities for regional action to leverage the existing infrastructure to overcome those barriers. With a lack of timely, geographic-specific, publicly-available source of sales data, NEEP developed this market snapshot to fill in the gap and paint a picture of residential heat pump sales in the Northeast and New York. The snapshot was developed by conducting research, performing interviews, and estimating data from a variety of sources.
