Formulas Used
Upfront Quote Total:
Upfront = Equipment + Labor + Fees − Rebates
Annual Energy Cost (new system):
AnnualCost_new = (BaselineKwh × BaseSEER / NewSEER) × ElecRate
The new system uses proportionally less energy based on the SEER ratio.
Annual Energy Savings vs. current system:
AnnualSavings = (BaselineKwh × ElecRate) − AnnualCost_new
Warranty Value (monetized):
WarrantyValue = (EquipWarrantyYrs + LaborWarrantyYrs) × AnnualServiceCallValue
Total Cost of Ownership over N years:
TCO = Upfront − (AnnualSavings × Years) − WarrantyValue
A lower TCO indicates better long-term value.
Value Score (higher = better):
Score = (AnnualSavings × Years + WarrantyValue) / Upfront × 100
Assumptions & References
- Baseline annual kWh represents your current cooling energy use. Check 12 months of utility bills or use an energy audit estimate.
