Used to calculate energy savings vs. your old unit.
Check your utility bills or use ~1,500–3,000 kWh for a typical home.
U.S. average ≈ $0.13/kWh (2024).
Typical HVAC lifespan is 15–20 years.
Used to monetize warranty years (avg. service call ~$150–$300).

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.
