Homeowners in Southern California can save thousands by switching to heat pumps instead of traditional gas furnaces and AC systems, with potential savings exceeding $10,000 due to various incentives. Heat pumps are more energy-efficient, pulling warmth from the air or ground, and they produce no on-site pollution, improving air quality. Financial incentives are also available in the UK and the U.S. to encourage this transition. The shift towards heat pumps is gaining momentum, with sales surpassing gas furnace shipments for the first time in 2022.
