HVAC Company Quote Comparison Calculator

Compare up to three HVAC contractor quotes side-by-side. Enter each quote's details to see a true cost-of-ownership comparison over your chosen time horizon, factoring in equipment cost, labor, warranty value, and estimated annual energy savings.

Field Quote A Quote B Quote C

Company Name

Equipment Cost ($)

Labor / Installation Cost ($)

Additional Fees (permits, disposal, etc.) ($)

SEER2 / Efficiency Rating

Equipment Warranty (years)

Labor Warranty (years)

Rebates / Discounts Offered ($)

Your Current System SEER (baseline)

Used to calculate energy savings vs. your old unit.

Current Annual Cooling Energy Use (kWh)

Check your utility bills or use ~1,500–3,000 kWh for a typical home.

Electricity Rate ($/kWh)

U.S. average ≈ $0.13/kWh (2024).

Ownership Horizon (years)

Typical HVAC lifespan is 15–20 years.

Est. Annual Service Call Value ($/yr)

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
