What Is SEER2? Understanding HVAC Efficiency Ratings
SEER2 measures cooling efficiency under an updated test standard. Higher is more efficient, but installation matters too.
SEER2 is the current way of rating the seasonal cooling efficiency of air conditioners and heat pumps.
What the number means
SEER2 compares cooling output to electricity used over a season. Higher numbers indicate better efficiency.
How it differs from SEER
SEER2 uses an updated testing method that reflects more realistic conditions, so the numbers are not directly comparable to older SEER ratings.
Beyond the rating
Real-world efficiency also depends on correct sizing, duct condition, airflow and maintenance. A high-efficiency unit installed poorly can disappoint.
