SEER Rating
Air conditioning efficiency is based on a SEER rating which stands for Season Energy Efficiency Rating. The higher the SEER rating, the greater efficiency of the air conditioner.
As of January 2006, the federal government mandates that all new central air conditioning equipment be at least SEER-13, but there is equipment available rated as high as SEER-18 and even SEER-23.
