Understanding Efficiency Ratings
- SEER - Seasonal Energy Efficiency Ratio (BTU/Wh over cooling season)
- EER - Energy Efficiency Ratio (BTU/Wh at specific conditions)
- COP - Coefficient of Performance (cooling kW / input kW)
- IEER - Integrated Energy Efficiency Ratio (part-load weighted)
Energy Saving Tips
- • Set thermostat 1-2°F higher to save 5-8% on cooling costs
- • Clean or replace filters monthly during peak season
- • Seal air leaks and improve insulation
- • Use programmable thermostat for automatic setbacks
