What is SEER?
SEER, Seasonal Energy Efficiency Ratio, is the maximum efficiency rating of an air conditioning system. This measurement is calculated by the cooling output for a typical cooling season divided by the total electric energy input during the same time frame.
Over the last decade, minimum SEER ratings have been raised which has led to more energy-efficient systems. In 2006, the minimum SEER rating was increased from 10 to 13. ENERGY STAR qualified central air conditioners had to have SEER rating of at least 14.5. In 2011, the US Department of Energy updated energy conversation rules that increased minimum standards and regional standards for HVAC systems. This approach allows for differences where cost-optimization due to climate variations across the country. The majority of today’s central AC units have a SEER rating between 13 and 25.
The higher the SEER rating, the more energy efficient the unit is – and the more you’ll save on cooling costs, approximately 5% less per SEER. For example, if your home has an older 12 SEER unit and you upgrade it to a higher efficiency unit with a rating of 16 SEER, it will be about 20% more efficient and be less costly to use.
