Angel Gomez (L) and Franes Mendez, technicians at heating, cooling and plumbing company John G. Webster, remove a gas water heater from a home in Washington, DC, on August 28, 2024. Heat pumps are an energy-efficient system for replacing both a heater and air conditioner in one appliance. Heat pump hot water heaters also exist. Hoping to spur heat pump uptake, the Inflation Reduction Act, President Joe Biden's 2022 landmark climate bill, provides up to $2,000 in tax credits for those installing either type.
