Heating & Cooling Calculator


Heating and cooling can account for more than half of your home’s total utility bill.* So when looking for ways to cut your energy costs, be sure to think about a high-efficiency system. High-efficiency systems are easily identified by reading the yellow-and-black EnergyGuide label found on the equipment.


  1. Click on the “Heating” or “Cooling” button on the top right of the calculator.
  2. Firstly, you can either use the default national average or you can select your state from the drop down list (if available). This helps determine fuel and electricity rates, which vary by region. (Canadian provinces are listed at the bottom of the menu.)
  3. Lastly, Select your current AFUE (for Heating) or SEER (for Cooling) efficiency rating on the slide selection bar. The efficiency rating you select will be compared to a base heating or cooling system in your area of residence.**

** Air conditioner calculations are based on every $100 spent to cool a home using a 3- ton, 13-SEER unit. The criteria base for furnaces is a 60% AFUE unit, with a 50,000-Btuh heating load. Fuel rates and heating hours are factored into the calculation upon selection of a state or region. If a state is not selected, the calculator defaults to the US national average for fuel and electricity consumption. Actual costs and savings will vary depending on weather conditions, usage, location and local utility rates. This information is intended as an example for comparison purposes only.
