Changes to Energy Efficiency Standards for Furnaces and Air Conditioners

This act modifies how federal energy efficiency standards for furnaces, central air conditioners, and heat pumps will be applied. Instead of applying to products installed after a certain date, the new rules will apply to products manufactured or imported into the U.S. after that date. This could affect the availability and cost of certain heating and cooling appliances in the market.
Key points
The effective date for regional energy efficiency standards for furnaces, air conditioners, and heat pumps is changing.
Standards will now apply to units manufactured or imported into the U.S., rather than those installed after the effective date.
