Cooling System Comparison Calculator

This calculator enables you to compare the cost to operate various cooling systems, as well as the cost to operate the same system under different rate structures, or rate discount programs. Since there is considerable variation in home energy use data (quality of construction, insulation values, number of windows, building tightness, set operating temperatures, and so on), the tool should only be used to provide a rough estimate of energy use for the different cooling options.

Before You Begin

You'll need the following pieces of information to complete the calculator.

  • Square footage of your home
  • Your current electric (kWh) cost as found on a recent utility bill
  • Efficiency ratings (SEER) of the cooling systems to compare - typical values are provided for reference; check nameplate specifications, the owner's manual, or ask a sales person for specific ratings
