text: There’s a New Minimum Efficiency Standard for 2006\nLike many consumer products that use energy, air conditioners and heat pumps are manufactured to meet or exceed minimum efficiency standards set by the U.S. Department of Energy. For nearly a decade, that minimum has been 10 SEER (Seasonal Energy Efficiency Ratio). On January 23, 2006, the minimum will jump to 13 SEER, a 30% increase over the current standard.
