Seer2 Information
What Is SEER2 All About? What Happened to SEER?
In a Nutshell:
SEER2 is the new DOE mandated standard efficiency metric that goes into effect January 1, 2023 which requires more stringent testing procedures than SEER thus lowering the SEER2 number to better replicate installation environments. Compared to SEER, SEER2 is roughly 4.5% lower of a number. Smaller does not mean worse, you are not losing efficiency. The new standards are actually increasing efficiency.
Full Detailed Explanation:
SEER2=Seasonal Energy Efficiency Ratio 2. Specifically, SEER2 is the total heat removed from the conditioned space during the annual cooling season. The new testing procedure referred to as "M1" will increase the systems' external static pressure by a factor of five to better reflect actual install environments of the equipment during testing. The goal of new SEER2 testing procedures is to better represent external conditions seen in the real world. Current SEER testing doesn't accurately simulate the influence of ductwork and external static pressures on HVAC products. Due to this, it is not often representative of real-world installation environements. By increasing systems
