Efficiency or SEER
The efficiency or SEER rating of an air conditioner refers to how much electricity that particular unit will consume to keep you cool in a season. SEER is an abbreviation for“seasonal energy efficiency ratio” and it tells you how much electricity an air conditioner will consume over a typical season. The higher the SEER the less electricity a unit consumes in a season.
Starting in 2007, the minimum SEER rating became 13. Before this, the efficiency levels went all the way down to 6 SEER or less. The actual savings every SEER number affords you varies, but on the average it is between 5 and 10 percent savings per larger number SEER selected.
