How the Free Weatherization Program Cuts Heating Bills
LIHEAP helps pay this winter's heating bill. Weatherization goes after the reason the bill is so high in the first place: air leaks, missing insulation and an old furnace. It's free for eligible households, renters included, but most areas have a waitlist, so the time to apply is before the cold sets in.
AT A GLANCE
|
A high heating bill isn't always about the weather or the rate. Often it's the house. Warm air escapes through gaps around doors and windows, an attic has little or no insulation, and an aging furnace burns more fuel than it should. Paying the bill doesn't fix any of that, so next winter's bill is just as high.
That's the gap weatherization fills. DOE describes the program as the nation's largest single "whole-house" energy efficiency program. Since it began in 1976, it has served more than 7.2 million families, and DOE says it reaches about 32,000 homes a year with DOE funds.
Weatherization, LIHEAP or emergency repair?
These three programs often run through the same local agency, and people mix them up. They do different jobs.
Program | What it does | When to use it |
|---|---|---|
LIHEAP (energy assistance) | Short-term help paying utility bills, funded by HHS | You have a bill due or a shutoff notice now |
Emergency heating repair | Fixes or replaces a broken furnace in a crisis (rules vary by state and agency) | Your heat is out or unsafe right now |
Weatherization (WAP) | Energy audit, then permanent upgrades such as air sealing, insulation and heating-system work | Your bills stay high every winter and you want to bring them down for good |
You can often apply for more than one. DOE notes that many states and local agencies combine WAP with other funding, including LIHEAP and utility programs, so they can do more work once they're inside the home.
Who qualifies
The federal rule (10 CFR 440.22) makes a home eligible if the household meets one of these tests:
Income at or below 200% of the federal poverty level
A household member received cash assistance under Title IV or XVI of the Social Security Act, such as SSI, at any time in the past 12 months
If the state chooses, the household qualifies for LIHEAP, as long as that standard is at least 200% of poverty
DOE's application guide notes states may use LIHEAP's 60% of state median income standard. Check your state's page on DOE's map for the exact limit.
Who gets priority
Local providers decide who goes first on the waitlist. DOE lists priority for:
Older adults
Families with one or more members with a disability
Families with children
High energy users
Households with a high energy burden, meaning energy costs eat up a big share of income
Both homeowners and renters are eligible to apply.
If you rent
Renters are eligible, and DOE says the provider will work with you and your landlord to get permission before any work begins. The federal rules add protections that matter to tenants:
The provider needs the owner's written permission.
The benefits have to go primarily to the low-income tenants, including tenants whose heat is included in the rent.
For a reasonable period after the work, tenants can't be hit with rent increases tied to the weatherization. States must set up a complaint process, and a landlord who raises the rent has to show it's for other reasons.
In apartment buildings, generally at least 66% of units have to be eligible (50% for duplexes, four-unit buildings and certain large multifamily buildings), unless the building is on DOE's list of qualifying HUD or USDA housing. States may also ask landlords of multifamily buildings to share the cost.
How to apply
Find your state weatherization office. DOE's How to Apply page has a map with links to every state, territory and tribal program.
Find your local provider. State sites usually list local providers by county, with an address and phone number. Roughly 700 local organizations do this work nationwide, mostly community action agencies, other nonprofits and local governments. Some states take applications online.
Apply with proof of income. DOE says your provider will ask for proof of the prior year's income, such as pay stubs or Social Security payments.
Get on the waitlist. If you're income eligible, your name goes on a waitlist. Ask where you are on it and how long the wait usually runs.
Prepare for the audit. When your home comes up, an energy auditor visits. Renters should make sure the landlord has signed off.
Before you call
☐ Proof of last year's income for everyone in the household (pay stubs, Social Security or SSI letters, unemployment statements)
☐ Proof of SSI or LIHEAP approval, if you have it
☐ Recent utility bills for heat and electricity
☐ Whether you own or rent, and your landlord's name and contact information if you rent
☐ Notes on problems you've noticed: drafts, cold rooms, ice dams, an old furnace or water heater
☐ Whether anyone at home is over 60, has a disability or is a young child, since those households get priority
What happens during the audit
DOE describes the energy audit as a computerized assessment of how your home uses energy. The auditor:
Reviews your energy bills
Runs a blower-door test to measure how much outside air leaks into the house
Inspects heating and cooling equipment and every part of the home, including living areas, the attic and the basement, for possible improvements and health and safety problems
The auditor then gives a recommended scope of work listing the most cost-effective upgrades for your home, and a crew leader explains how the work will be done and how long it will take. After the crews finish, an inspector checks that the work was completed, meets DOE's Standard Work Specifications, and that all equipment runs safely.
What kind of work can be done
Federal rules only allow measures that pay for themselves in energy savings over their lifetime, plus health and safety fixes needed for the work. The regulations list materials such as:
Category | Examples from the federal rules |
|---|---|
Air sealing | Caulking and weatherstripping doors and windows |
Insulation | Attic floors, walls, floors, ceilings and roofs; pipes, ducts and equipment |
Heating system | Replacement burners, furnaces or boilers, venting improvements, and electronic ignition in place of a standing pilot light |
Cooling | Replacement air conditioners, ventilation, screens, window films and shading |
Water heating | Insulating the tank and pipes |
Windows | Storm windows |
Repairs | Small repairs needed for the upgrades to work, such as fixing a window frame so it can be sealed |
Not every home gets every item. The audit decides, and federal rules cap average spending per home, so crews do the work that saves the most first.
A few limits to know
Repeat work is restricted. Federal rules limit using program funds again on a home that was already weatherized under the program, with exceptions such as uninsured fire or flood damage. If your home was done years ago, ask your provider whether it qualifies again.
Homes slated for demolition are out. Funds can't go to a home scheduled for acquisition or clearance by a government program within 12 months of when the work would finish.
Expect a wait. DOE's own process puts eligible households on a waitlist. Applying in late fall can mean work in spring or later, so apply for LIHEAP too if this winter's bills are the urgent problem.
