Drafty windows, thin insulation and aging furnaces waste energy and money. The federal Weatherization Assistance Program, run by the US Department of Energy through state and local agencies, helps eligible households make their homes more energy efficient at no cost to them. The result can be lower energy bills and a safer, more comfortable home.
What weatherization can include
Every home starts with an energy audit, in which a trained inspector checks where your home is losing energy and whether there are safety problems. Based on the results, services may include:
- Insulation in attics, walls and floors.
- Air sealing around doors, windows, pipes and other gaps.
- Heating and cooling system tune-ups, repairs or replacement.
- Water heater repairs or insulation.
- Health and safety checks, such as testing for carbon monoxide and gas leaks, and installing smoke and carbon monoxide alarms.
- Energy-saving lighting and appliances in some cases.
Who qualifies
Eligibility is based mainly on household income. In general:
- Households with incomes at or below 200% of the federal poverty level may qualify.
- Households that receive SSI or certain other assistance may qualify automatically.
- Many states also use LIHEAP eligibility rules.
States give priority to households with people 60 and older, people with disabilities and families with children, as well as households with high energy costs relative to income.
Funding
Weatherization is funded by Congress. For fiscal year 2026, the program received about $329 million, slightly more than the year before. Because funding is limited, there may be a waiting list in your area.
Renters
Renters can receive weatherization services if the landlord agrees. Agencies may ask landlords to contribute to the cost and agree not to raise the rent because of the improvements.
How to apply
- Find your local weatherization agency. The Department of Energy's website lists state contacts. Your Area Agency on Aging or community action agency can also help.
- Ask about eligibility and waiting lists.
- Gather documents, such as proof of income for everyone in the home, recent utility bills and proof of ownership or a landlord's permission.
- Schedule your energy audit. A crew will then complete the approved work.
Combine with other help
Weatherization pairs well with LIHEAP, which helps pay energy bills, and utility company efficiency programs, which may offer rebates or free energy audits. See help with heating and cooling bills through LIHEAP and practical ways to lower your utility bills.
