Limitations of SEER for measuring efficiency.

Summary

Conventional wisdom assumes that a 30% increase in the seasonal energy efficiency ratio (SEER) of a unitary air conditioner or heat pump will result in a 30% decrease in energy consumption. In fact, a 30% increase in SEER will result in a 30% increase in efficiency when the outdoor temperature is 27.8°C and the indoor temperature is 26.7°C, the specified rating conditions. Prediction equipment with a single indicator can be "seriously inaccurate". As an example, the performance data of an 18-SEER product line is compared to a 10-SEER product line from the same manufacturer.
