How to Apply for Weatherization Assistance

What Weatherization Assistance Does and Who Runs It

Weatherization Assistance is a federal program that pays for repairs to your home that reduce heating and cooling costs — things like insulation, air sealing, fixing furnaces, or replacing windows. Unlike LIHEAP, which helps you pay your energy bills directly, Weatherization fixes the building itself so your bills stay lower going forward. The program is run by your state's energy office or department of community affairs, which contracts the actual work to local nonprofits in your area.

The work is done at no cost to you. A contractor comes to your home, does an energy audit to find where heat or cold is escaping, and then performs the repairs. You do not pay upfront or later — the program covers everything. This matters especially if you have a disability that makes temperature control important for your health, or if you cannot afford to fix a broken heating system on your own.

Key Takeaways

• Weatherization is run by your state energy office through local nonprofit contractors, not by a single national program you call.
• You must own or rent your home, have a household income below 200% of the federal poverty line (the exact limit varies by state), and live in the home year-round.
• The first step is to find your local weatherization agency by calling your state energy office or searching the Department of Energy's agency finder.
• The process from application to completed work typically takes two to four months, depending on how busy your local agency is and what repairs your home needs.
• If you rent, your landlord must sign a form giving permission for the work, but you can still apply even if you think they might refuse.

Income Limits and Who Can Apply

To be considered for Weatherization, your household income must fall below a certain threshold. Most states use 200% of the federal poverty line, though some use 150% or have their own limits. For 2024, 200% of poverty for a single person is roughly $28,000 per year, and for a family of four it is roughly $57,000 — but these numbers change yearly and vary by state. Your state energy office can tell you the exact limit that applies to you.

You must own or rent the home where you live, and you must live there year-round. The program does not cover vacation homes, investment properties, or seasonal residences. If you rent, your landlord must consent to the work in writing, but the program will contact them directly — you do not have to ask first. If you own your home, you need proof of ownership or a mortgage statement.

Having a disability does not change the income rules, but it can affect which repairs get priority. If you have a medical condition that requires stable temperature — such as asthma, heart disease, or arthritis — tell the contractor during the energy audit. They may prioritize furnace repair or insulation work that keeps your home at a safe temperature.

How to Find Your Local Weatherization Agency

Weatherization is delivered through local agencies, not a central office. Your state energy office oversees the program but does not do the work itself. To find the agency that serves your area, start with the Department of Energy's Weatherization Assistance Program finder at wap.ornl.gov. Enter your state and sometimes your county, and it will list the local agencies near you with their phone numbers and addresses.

If the online finder does not work or you prefer to call, contact your state energy office directly. You can find the number by searching "[your state] energy office" or by calling 211, which has a database of local programs. When you call, have your zip code ready and ask which local agency handles Weatherization in your area. They will give you the phone number to call next.

Some areas have long waiting lists, especially in winter when demand is high. When you call the local agency, ask how long the wait is and whether they are currently taking new applications. If the wait is very long, ask if there is a priority list for people with disabilities or urgent heating or cooling needs.

What You Need to Bring to Your Application

When you contact your local Weatherization agency, they will ask you to come in or mail documents to start the process. Have these items ready: proof of income (recent pay stubs, tax returns, or a letter from Social Security if you receive benefits), proof of residency (a utility bill or lease in your name), and proof of ownership or tenancy (a mortgage statement, deed, or signed lease). If you are applying on behalf of someone else, bring a power of attorney or guardianship papers.

If you rent, bring a copy of your lease and be prepared to provide your landlord's name and contact information. The agency will reach out to your landlord separately to get written permission for the work. You do not need the landlord's permission before you apply — the agency handles that step.

Bring any documents about your home's heating or cooling system: a recent utility bill showing what you pay, a service record if you have had repairs done, or photos of visible damage like broken windows or gaps around doors. If you have a disability that affects your heating or cooling needs, bring medical documentation or a letter from your doctor explaining why temperature control matters for your health. This is not required, but it can help the contractor prioritize the right repairs for you.

The Application and Inspection Process

After you submit your application and documents, the agency will verify your income and residency. This usually takes one to three weeks. Once you are approved, the agency will schedule an energy audit — a visit where a contractor walks through your home, checks for air leaks, tests your furnace or air conditioner, and looks at insulation and windows. The audit is free and takes one to two hours. The contractor will ask about any comfort problems you have, such as rooms that are always cold or hot, or drafts you feel.

After the audit, the contractor writes a report listing the repairs that will save you the most energy. Not every possible repair gets done — the program prioritizes work that has the biggest impact on your heating and cooling costs. If you have a disability that makes certain repairs especially important (like fixing a broken furnace if you have a respiratory condition), mention this during the audit. The contractor can note it in the report.

You will get a copy of the audit report and a list of the work that will be done. If you have questions about why certain repairs were chosen or not chosen, ask the contractor or call the agency. You can also ask about the timeline — when the work will start and how long it will take.

What Happens During and After the Work

Once the work is scheduled, the contractor will come to your home on the agreed date. The work might include sealing air leaks with caulk or weatherstripping, adding insulation to your attic or walls, repairing or replacing your furnace or air conditioner, fixing or replacing windows, or installing a programmable thermostat. Depending on what needs to be done, the work might take a few days or several weeks. You do not pay anything, and you do not need to be home for all of it, though the contractor may need access to your home.

After the work is finished, the contractor will do a final inspection to make sure everything is done correctly. They will show you what was repaired and explain how to use any new equipment, like a programmable thermostat. You should receive a summary of the work completed and the estimated energy savings.

Keep the paperwork from the completed work. It documents what was done to your home and can be useful if you ever sell the home or need to show proof of repairs for insurance or other purposes. Your energy bills should start to drop in the months after the work is finished, though the savings depend on how much work was done and how you use your heating and cooling.

What to Do If You Are Denied or Put on a Waiting List

If the agency denies your application, they must tell you why. Common reasons are income above the limit, not living in the home year-round, or the home being ineligible (such as a mobile home that cannot be safely weatherized). If you believe the decision is wrong, ask the agency for an appeal process. Most agencies have a way to challenge a denial.

If your area has a waiting list, ask the agency how long it typically is and whether you can be added to a priority list. Some areas prioritize elderly people, people with disabilities, or homes with broken heating systems. If you have a medical need for heating or cooling repairs, provide documentation and ask if it moves you up the list. In the meantime, you might be able to get help with heating or cooling costs through LIHEAP while you wait for Weatherization.

If your local agency is not taking applications, ask when they expect to reopen and whether you can call back to check. Funding for Weatherization comes from the federal government and is distributed to states, so availability changes throughout the year. Some areas have more funding in winter or spring than in summer.

Frequently Asked Questions

Do I have to let the contractor into my home if I feel uncomfortable?

You can ask questions about the contractor's credentials and what the audit involves before they enter. The agency can provide the contractor's name and background. You can also ask a family member or friend to be present during the visit. If you are not comfortable with a particular contractor, tell the agency and ask if someone else can do the audit.

What if my landlord refuses to sign the permission form?

Some landlords worry about liability or disruption. The agency can explain to your landlord that the work improves the property and that they are protected by liability insurance. If your landlord still refuses, you cannot proceed with Weatherization in a rental home — the program requires landlord consent. You might explore other options like LIHEAP to help with energy bills while you are renting.

Will Weatherization work on a mobile home or apartment?

Mobile homes can sometimes be weatherized, but not all contractors are trained to do it safely. Apartments are usually not may be able to access because the landlord owns the building and the agency cannot make permanent changes without their agreement. Ask your local agency whether your specific home type can be served.

How much money will I save on my energy bills?

Savings vary widely depending on what repairs are done and how you use your heating and cooling. The contractor's audit report will include an estimate, but actual savings depend on weather, how you adjust your thermostat, and other factors. Most people see a noticeable drop in their winter or summer bills within the first year.

Can I apply if I am behind on my energy bills or have a shut-off notice?

Weatherization does not pay past-due bills — that is what LIHEAP does. However, you can apply for both programs at the same time. If you have a shut-off notice, contact your utility company and your local LIHEAP program immediately, as that is more urgent than Weatherization. Once your immediate crisis is handled, Weatherization can help prevent future bills from being so high.
