What do SEER and EER stand for?
SEER stands for the Seasonal Energy Efficiency Rating. EER stands for Energy Efficiency Ratio. The U.S. government requires an efficiency rating of all air conditioning equipment. There are special names for the efficiency ratings of various types of equipment. Air conditioning equipment is rated by the Seasonal Energy Efficiency Rating, or SEER. The higher the SEER rating, the more efficient the unit. Even though the Energy Efficiency Ratio or EER is not required to be posted by the government, it is similar to the SEER rating, except that the EER rating is a tougher testing process. An EER rating is based on a tougher heat load performance test and this means that the higher the EER rating, the more efficient the unit when it is under tough loads more similar to real life cooling.
