Comparison Tool

Your choices of home energy systems and appliances affect your energy costs for years to come. This Comparison Tool is designed to help you make more informed decisions regarding these systems.

Use the Comparison Tool to quickly compare the annual energy use and costs to operate heating and cooling equipment, water heaters, or lighting in your home. You can compare two new appliances or a new appliance with an existing appliance already installed in your home. The Comparison Tool also allows you to estimate the amount of time (simple payback period) it will take to recover your cost for a new system or the incremental cost for purchasing a more efficient system. Monthly bill savings are also estimated using current average energy costs in your area.

Get started by selecting the system of your choice below. For more detailed information on the Comparison Tool click here. To view or modify the energy costs used for your local area click here.
