Government decarbonization strategies call for widespread deployment of heat pumps for building heating and cooling, but experts warn of retrofit costs, disruption and other concerns.
Heat pumps are gaining recognition across many parts of the U.S. for their energy efficiency and reduced greenhouse gas emissions compared with other building heating and cooling options.
The U.S. Climate Alliance, a bipartisan coalition of 25 governors, recently pledged to increase heat pump installations across their states to reach 20 million by 2030. Currently, the U.S. has about 4.8 million heat pump installations, according to RMI, a clean energy think tank.
Adoption varies from state to state. In Massachusetts, concerns about initial expenses and the intricacies involved in selecting appropriate heat pump equipment have slowed adoption, putting the state behind counterparts like Maine, which has already surpassed its 2025 target of 100,000 heat pumps. Maine Gov. Janet Mills, D, recently established a more ambitious target of reaching 175,000 heat pumps by 2027.
