The Air-Conditioning and Refrigeration Institute (ARI) recently called for a 20% increase in federal minimum efficiency standards for central air conditioners and heat pumps used in homes across America and urged adoption of targeted tax incentives to encourage purchase of equipment that reduces use of electricity.

Central systems are rated by the seasonal energy efficiency ratio (SEER) and ARI said manufacturers are unified in support of the U.S. Department of Energy increasing the current minimum SEER 10 to 12. ARI said tax incentives enacted by Congress and the states would encourage purchase of higher efficiency equipment and especially benefit California and other parts of the country suffering from electricity shortages. "The industry can support a 12 SEER minimum efficiency standard," said ARI.
