Both types begin to lose their effectiveness with increasing humidity, because humid air is less able to carry additional moisture. Instead of using a seasonal measure, the EER constant state measures the cooling performance of ground source heat pump. The minimum requirements for ground source heat pumps in the ENERGY STAR program are 21.1 EER (open-loop), 17.1 EER (closed-loop) and 16 EER (16 for direct expansion units).
Central air conditioners and air-source heat pumps operating in the cooling mode have been rated according to their seasonal energy efficient ratio since 1992. SEER is the seasonal cooling output in Btu divided by the seasonal energy input in watt-hours for an "average" U.S. climate.
