The Weatherization Assistance Program (WAP) is one of the cornerstone services provided throughout the Community Action network, helping income-eligible families reduce the burden of high home energy costs while creating safer, healthier, and more comfortable living environments.
Through a comprehensive home energy assessment, the program implements energy-efficient improvements that may include insulation, air sealing, heating and cooling system enhancements, and other cost-saving measures designed to improve a home’s overall energy performance.
For decades, weatherization has helped families lower utility bills, increase home comfort, and improve indoor air quality. We invite you to explore the resources, videos, and success stories throughout this section to learn how weatherization can make a lasting difference for your household.
Join the growing number of families whose homes have been upgraded to save money, conserve energy, and promote healthier living for years to come.

A home energy assessment, also known as a home energy audit, can help you understand the whole picture of your home’s energy use, comfort, and safety. An assessment can help you determine how much energy your home uses, where your home is inefficient, and which problem areas and fixes you should prioritize to save energy and improve the comfort of your home. A home energy assessment should be your first step before making energy-saving home improvements, as well as before adding a renewable energy system to your home.
