The White House utilizes the Defense Production Act to mobilize the production of heat pumps.

Giulia Siccardo, director of the Energy Department's Office of manufacturing and energy supply chains, told The Hill that the $169 million in funding the department announced Friday would allow companies to construct factories to build heat pumps.

The funds come from the Inflation Reduction Act — the Democrats' big spending climate, tax, and health care law.

"Most of the companies that we announced today, seven out of the nine, are actually not yet manufacturing heat pumps here in the U.S., or heat pump components, in the U.S.Amer at scale," Siccardo said.
