Even before Inflation Reduction Act incentives kicked in, Americans bought more heat pumps than ever before last year — well over 4 million.
… Heat pumps run on electricity instead of fossil gas and are up to three times more efficient than gas furnaces for heating. Plus, they can also act as air conditioners when the weather is warm, serving as a double-duty appliance.
So far in the U.S., heat pumps have been most common in the Southeast, where many homes are already all-electric and winters tend to be more mild. But their adoption has been increasing across the country over the past 10 years. That is due partly to falling costs and partly to technology improvements that have significantly boosted heat-pump performance, especially in colder weather.
