Summary:

- The article discusses the challenges and limitations of heat pump subsidies as a policy measure to promote the adoption of energy-efficient heating and cooling systems.
- It argues that while heat pump subsidies can be helpful, they are often not enough to overcome the higher upfront costs and other barriers that prevent widespread adoption, particularly among low-income households.
- The article suggests that a more comprehensive approach, including education, training, and addressing other infrastructure and regulatory barriers, is needed to truly drive the transition to heat pump technology.
