SEER stands for Seasonal Energy Efficiency Ratio, the standard measurement of air conditioning efficiency established by the U.S. Department of Energy. More importantly, higher SEER ratings translate into greater energy efficiency. Just remember, the higher the SEER rating, the more money you save.

Why a higher efficiency rating (SEER) can save energy:
If your current air conditioner or heat pump is more than 10 years old, it could be operating at lower than 8.00 SEER Compare the estimated annual bill of an 8.00 SEER system to that of a higher SEER, such as a 12.00 or 13.00. For instance, if the annual cooling bill of an 8.00 SEER system was $1,000, it could potentially cost only $615 for a 13.00 SEER system, or an annual savings of 38%.
