SEER2 (Seasonal Energy Efficiency Ratio 2) measures cooling efficiency. As of 2023, this updated testing standard replaced SEER. Higher numbers mean better efficiency and lower operating costs.
Standard Efficiency
Meets minimum requirements; good for budget-conscious buyers
High Efficiency ⭐
Best value; qualifies for rebates and tax credits
Premium Efficiency
Maximum savings; ideal for hot climates with heavy AC use
For a 2,000 sq ft home in a hot climate running AC 6 months/year:
14 SEER2 System
$1,200/year
16 SEER2 System
$1,050/year
Save $150/year
20 SEER2 System
$840/year
Save $360/year
Annual Fuel Utilization Efficiency measures how much fuel converts to heat:
Heating Seasonal Performance Factor 2 rates heat pump heating efficiency:
| Region | States | AC Minimum | Heat Pump Minimum |
|---|---|---|---|
| North | Most northern states, Midwest | 14 SEER2 | 15 SEER2 / 8.8 HSPF2 |
| South | Southeast, Texas, southern plains | 15 SEER2 | 15 SEER2 / 8.8 HSPF2 |
| Southwest | Arizona, Nevada, New Mexico, California | 15 SEER2 | 15 SEER2 / 8.8 HSPF2 |
