What is SEER®?
SEER® stands for seasonal energy efficiency ratio.
The higher the SEER rating, the more energy efficient the equipment is. A higher SEER can result in lower energy costs. This U.S. Dept. of Energy Website can show how to calculate the potential energy cost savings of a more efficient unit. The Air-Conditioning and Refrigeration Institute (ARI.org) posts a Certified Rating directory, which lists SEER ratings of various air-conditioning equipment
