Why Heat Pumps Are Still So Hot in the US

Heat pumps are quietly becoming America's fastest-growing home-heating technology, jumping 30% in installations over the last two years.

Unlike traditional furnaces, these devices move heat rather than generate it, slashing household energy bills and cutting carbon emissions in most regions.

New federal tax credits have made the upfront cost far more accessible for middle-class families, while improved cold-climate models now work even in northern states.

Despite the boom, critics still worry about electricity grid strain during extreme cold snaps and whether older neighborhoods can handle the electrical upgrades.

If heat pumps keep improving this fast, could they soon replace not just furnaces, but also air conditioners in millions of homes?
