Savings % for Cooling Your Home
SEER=Seasonal Energy Efficiency Ratio
- 13 seer 38% savings
- 14 seer 43% savings
- 15 seer 47% savings
- 16 seer 50% savings
- 17 seer 53% savings
- 18 seer 56% savings
A higher SEER means a system is more energy efficient and provides comfort at a lower monthly utility cost than a lower SEER system.
AFUE=Annual Fuel Utilization Efficiency
For heating systems, the unit’s Annual Fuel Utilization Efficiency (AFUE) rating will help you determine how much energy the equipment uses. The federal minimum AFUE rating is 78 percent, but for maximum efficiency, look for a rating in the 80s or 90s.
