How to Use the Whole House Generator Sizing Calculator

Using our free whole house sizing calculator is simple and will give you recommendations in three quick steps:

  1. Enter your home's square footage and ZIP Code. This information is used later in the calculation as a baseline.
  2. Select the size of your air conditioner.Since central air conditioners typically use more wattage than any other appliance in your home, you will want to make sure you get a generator that can handle the load.
  3. Select what you want to keep powered during an outage. If you select Whole House,the tool provides a backup generator recommendation based on your home's size, corresponding outlets and lighting requirements and assumes natural gas appliances in the baseline calculation. You can also add appliances into the calculation from our preset list or manually insert your own The tool is fully customizable.
