According to nonprofit Build Decarbonization Coalition, over the past 15 years, heat pump sales in the United States have doubled. For 2026 specifically, their research found that heat pump shipments surpassed fossil fuel furnaces by 32% in the first quarter of the year. The difference between heat pump sales and air conditioner sales was a 2% gap. She reported that in just this year alone, heat pump rebate applications accounted for almost half of all the rebate applications they are receiving. “I think we’re seeing heat pump installation outpace fossil fuel furnaces nationwide, and we’re definitely seeing a large uptick in heat pump adoption here in our territory.”
