Weatherization help for mobile homes
Older manufactured homes can be expensive to heat and cool. The federal Weatherization Assistance Program (WAP) pays for energy-saving improvements for income-eligible households — often at no cost. Here's how it works.
Published June 4, 2026
Older manufactured homes are notorious for being expensive to heat and cool — thin walls, aging insulation, and leaky ducts add up fast on a utility bill. The federal Weatherization Assistance Program (WAP) exists to fix exactly that, paying for energy-saving improvements for income-eligible households, often at no cost to the resident. This article explains how it works. It is general information; eligibility and details are handled by local providers.
What WAP pays for
After an energy audit to find where a home wastes the most energy, a WAP provider may install or repair:
- Insulation and air sealing to stop heat and cooling loss;
- Heating and cooling system repairs or safety fixes;
- Ductwork sealing and minor related repairs; and
- Health-and-safety measures tied to the energy work.
The goal is to lower energy bills and make the home safer and more comfortable, prioritizing the improvements that save the most for the cost.
Manufactured homes qualify — and benefit
Manufactured and mobile homes are eligible, and they're often among the best candidates because the savings can be large. Whether you own the home or rent it, the provider can explain how your situation is handled — there can be extra steps when the occupant isn't the owner.
Who can qualify
WAP is income-based. The income limits fall within federal guidelines but are administered locally, and in many states a household that already receives LIHEAP, SSI, or certain other benefits qualifies automatically. Priority often goes to seniors, people with disabilities, and families with children.
How to apply
- Find your local weatherization provider through your state energy office, a community action agency, or the Department of Energy's WAP page;
- Call 211 to be pointed to the nearest provider; and
- Expect a waiting list in some areas — apply early and stay in touch.

Frequently asked questions
- What is the Weatherization Assistance Program?
- WAP is a federal program, run through state and local agencies, that pays for energy-efficiency improvements in the homes of income-eligible households — things like insulation, air sealing, and heating-system fixes. For qualifying households the work is typically provided at no cost. This is general information; check your local provider for specifics.
- Can a manufactured home be weatherized?
- Yes. Manufactured and mobile homes are eligible, and they often benefit a great deal because older units lose heat and cooling easily. A WAP provider usually starts with an energy audit and then makes the improvements that save the most energy for the cost.
- Who qualifies, and how do I apply?
- WAP is income-based; income limits are set within federal guidelines and administered locally, and households receiving certain benefits (like LIHEAP or SSI) may qualify automatically in some states. Apply through the local weatherization provider — find it through your state energy or community-action office, or the Department of Energy's WAP page.
