The deadline to apply to the Air District’s Clean HEET Program has been extended to September 30, 2025. Clean HEET grants are currently available to help offset the cost of switching from wood-burning or pellet-burning stoves, fireplace inserts, or open-hearth fireplaces to an electric heat pump. A decommission-only option is also available for homeowners to remove existing open-hearth fireplaces or older, uncertified wood-burning stoves or inserts.
