"The U.S. Department of Energy (DOE) published new minimum energy efficiency standards for residential central air conditioners and heat pumps today.  The new standards, which are based on a negotiated agreement, will reduce air conditioner and heat pump energy use by about 7%, translating into hundreds of dollars in electricity bill savings for consumers over the life of their equipment."
