Compare two AC units with different SEER2 ratings side by side. See the efficiency difference when upgrading to a more efficient system.
The annual kWh formula is: (BTU × Cooling Hours) ÷ (SEER2 × 1,000). We calculate this for both your current and potential new unit, then show the difference in energy consumption. The 15-year projection assumes consistent usage patterns.
