What Is SEER2?
SEER2 is the updated standard for measuring air conditioner and heat pump efficiency, introduced in 2023 to replace the older SEER rating system. This newer rating metric provides more accurate real-world performance measurements by incorporating higher external static pressure during testing. The testing accounts for the resistance created by ductwork, filters, and other components in actual home installations.
The SEER2 rating calculates how much cooling output your system delivers per watt of electricity consumed over an entire cooling season. Higher SEER2 numbers mean better efficiency and lower operating costs. A 13.4 SEER2 system uses significantly less energy than older units. For example, upgrading from a 10 SEER system to a 13.4 SEER2 could reduce cooling costs by about 25%.
Federal regulations now require minimum SEER2 ratings that vary by geographic region. Northern states must meet at least 13.4 SEER2, while southern regions require 14.3 SEER2 for new installations. Understanding SEER2 ratings helps you compare systems and evaluate long-term value versus upfront costs.
