What Is SEER2?
SEER2 represents the latest standard for measuring the efficiency of air conditioners and heat pumps, replacing the older SEER rating system in 2023. This updated metric provides a more accurate reflection of real-world performance by incorporating higher external static pressure in testing procedures, better accounting for the resistance created by ductwork and air filters in actual home installations. The SEER2 rating calculates how much cooling output (measured in BTUs) your system delivers per watt of electricity consumed over an entire cooling season.
Higher SEER2 numbers indicate better efficiency, meaning your system produces more cooling while using less electricity, which directly translates to lower monthly utility bills. A 15.2 SEER2 system uses significantly less energy than older systems. For example, upgrading from a 10 SEER system to a 15.2 SEER2 system could reduce your cooling costs by approximately 35%. The federal government has established minimum SEER2 requirements that vary by geographic region, with northern states requiring at least 13.4 SEER2 and southern regions mandating 14.3 SEER2 for new installations. Understanding SEER2 ratings helps you compare different systems and assess the long-term value of higher efficiency options versus their additional upfront costs.
