What is the difference between SEER and SEER2?
Friday, September 9, 2022
SEER2 is an updated version the original SEER energy efficiency rating system for air conditioners and heat pumps. It has raised the external static pressure requirement for testing, which the Department of Energy has determined will more closely resemble real-world conditions. External static pressure is the sum of all the external pressures, both positive and negative, that the blower has to work against—such as air filters, registers, and ductwork friction.
This added factor means that the SEER2 rating of an HVAC system will be a little less than the old SEER rating. The mandate for manufacturers to use SEER2 testing goes into effect on January 1, 2023, along with new, higher energy efficiency standards.
