Most programs that help with utility costs put money toward a bill you already owe. Weatherization works differently. Rather than paying a bill, it sends a trained crew to make permanent improvements to your home so it uses less energy, which lowers what you pay every month from then on. The work is free, funded by the U.S. Department of Energy and carried out by local agencies in your state. This page explains what the work usually includes, what it will not cover, how the process runs from start to finish, and how to apply where you live.

It is not a loan, and nothing is paid back. The savings stay with you for as long as you live there. No two homes get the same work. Weatherization starts with an energy audit — a professional inspection of your specific home to find where it leaks heat, wastes power, or runs unsafely. What the crew installs is based on what that audit shows will save the most, so an older drafty house and a newer one are treated very differently.

What the crew often installs in your home

Once the audit is done, the work targets the places your home loses the most energy. The most common measures are sealing air leaks around doors, windows, and gaps in the walls, and adding insulation in the attic, walls, and floors — the quiet improvements that cut heating and cooling costs the most.

From there it depends on the home. Crews often seal and repair leaky heating ducts, and many state programs will repair or even replace a furnace, boiler, or heating system that is broken or unsafe to run. The work can also include a more efficient water heater, better ventilation to keep indoor air healthy, and energy-saving LED lighting.

Safety is also part of every job: the crew checks that heating equipment runs safely and tests for hazards like carbon monoxide, because a warmer home that is not safe helps no one. Across all of it, the improvements may lower energy bills by hundreds of dollars a year for a typical household, though the exact savings depend on the home.

What Weatherization will not cover

It helps to know the limits before you apply, because weatherization is not a free home remodel. The program pays only for work tied to energy use, health, and safety — not cosmetic updates, general repairs, or plumbing problems unrelated to energy. A crew will not remodel a kitchen, fix a dripping faucet, or finish a basement.

There is also a practical limit: if a home has a serious problem that blocks the work, such as a badly damaged roof, heavy moisture, or unsafe wiring, the crew may not be able to weatherize it until that issue is handled. Some programs can make limited repairs so the work can move forward; others will refer the home for those fixes first. Your local agency can tell you what applies to your situation.

How the process works, step by step

Weatherization runs on a set sequence, and knowing it helps the timeline make sense. First you apply through your local agency and show that your household income qualifies. If it does, the agency schedules the energy audit, where an inspector walks through your home and builds a list of the improvements that will save the most. A trained crew, often working through a community action agency, then carries out that work.

When they finish, an inspector returns to check that everything was done correctly and safely. The whole process takes time, and because more people apply than there is funding for, waiting lists are common. What makes the wait worth it is that the improvements are permanent, so they keep lowering your bills for years rather than for a single season.

Who qualifies — homeowners and renters

Eligibility is based on household income, and in most states you may qualify if your income is at or below 200% of the federal poverty level. Some states use a different measure, such as 60% of the state's median income, so the exact limit depends on where you live.

If you already receive LIHEAP, SSI, or TANF, you are usually eligible for weatherization automatically, with no separate income review. Renters qualify too, not only homeowners — but because the work improves someone else's property, your landlord has to agree to it in writing first. That agreement does not put a lien on the home or create any ongoing cost for you. Priority generally goes to households with an older adult, someone with a disability, a young child, or unusually high energy bills.

How to apply for Weatherization

Weatherization is run by the same local agencies that handle LIHEAP, usually a community action agency or your state's weatherization office, and you apply locally rather than through the federal government. The best place to start is your state below, which covers that state's income limits, contacts, and how to get on the list.

To confirm the basics directly, the Department of Energy explains how the program works and links to every state office on its how to apply for weatherization page at https://www.energy.gov/cmei/scep/wap/how-apply-weatherization-assistance, and USA.gov has a plain guide at https://www.usa.gov/weatherization-energy-programs to checking eligibility and finding your state's program. It is also worth asking your own utility company what it offers, since many run their own energy efficiency and rebate programs separate from the government one.

Weatherization programs by state

Choose your state for its weatherization rules, income limits, local contacts, and how to apply. Because most states run weatherization alongside LIHEAP, each page covers both the bill-payment help and the home-improvement program together.

One caution before a crew shows up

Real weatherization is always free, and it is arranged only after you apply and qualify through a local agency. No legitimate program sends someone to your door unannounced asking for payment, a deposit, or your bank account details to schedule "free" work. If that happens, do not pay or hand over any information — call your local community action agency or state weatherization office to confirm what is real before letting anyone start.

Community feedback in the forum

You can also read what others around the country have experienced, and share your own, in the moderated forum on weatherization and energy programs. There you will find real-world experiences from people across the country when it comes to their utility bills and what they have done or where they have received help - whether from weatherization or another program.

This page is a general, plain-English guide to how the Weatherization Assistance Program works across the country. It is not legal or financial advice, and income limits, covered measures, and waiting times are set locally and change over time — confirm the current details with your state's weatherization office or local community action agency before you apply.
