Heating/Cooling Comparison Tool
Compare heating and cooling systems by installation cost, operating cost, annual savings, payback period, and CO2 reduction.
For this tool you will need your electricity price, fossil fuel price, heating zone, and the installation cost assumptions for each system.
Contact and Energy Inputs
Values and formulas match the Heating sheet from the new spreadsheet.
Spreadsheet default: $0.175/kWh.
The calculator converts the entered base price using the sheet's fuel price factor.
Spreadsheet default: 1.4. Effective fuel price is factor x base price.
Choose the eGRID subregion for your electricity source, or use Natural Gas or Coal.
Use the eGRID Subregions Map in the
Carbon Footprint Calculator
to find your subregion.
Spreadsheet Heating tab supports Zone 2 through Zone 6.
Furnace A/C is the baseline system. Savings, payback, % CO2 reduction, CO2/$, added electricity, and solar panels needed are calculated for each alternative against Furnace A/C.

Installation Costs
Defaults are from row 7 of the Heating sheet.
Adjust inputs to update the model, then export the report.
