LIHEAP, weatherization, and utility rebates: how free energy upgrades actually work

Updated June 2026 · The Grant Map tracks 59,000+ home improvement programs across 2,200+ US cities

If your heating bill hurts or your house leaks air like a screen door, three different kinds of help exist, and almost every article online mashes them together into one vague pile of "free energy assistance." They are not the same program. They have different applications, different income rules, and different things they will pay for. Mixing them up is how people end up applying to the wrong office, getting denied, and giving up on money they actually qualified for.

Here is the clean version: LIHEAP pays your energy bill. Weatherization upgrades your house. Utility rebates knock money off equipment you buy. This guide covers what each one does, who qualifies (and who does not), where you actually apply (it is not a federal website), and the order to do them in so each program sets up the next.

The three systems, in one minute

• LIHEAP (the Low Income Home Energy Assistance Program) is bill help. It sends money to your utility company to cover heating or cooling costs, stops shutoffs through its crisis component, and in many states will repair or replace a broken furnace. It is income-gated and seasonal.
• The Weatherization Assistance Program (WAP) is the free whole-house upgrade: a professional energy audit, insulation, air sealing, duct work, and often furnace repair or replacement, at no cost to you. Income-gated, with real waitlists.
• Utility rebates come from your electric or gas company, not the government. Heat pumps, insulation, smart thermostats, water heaters. Usually no income test, usually faster, usually smaller dollar amounts per item.

Our directory holds 59,181 programs across 2,203 cities as of June 2026, and the energy cluster is one of the biggest slices of it. The numbers below come straight from that dataset, so you can see what is typical rather than what a press release promised.

LIHEAP: help with the bill, plus crisis aid

LIHEAP is a federal block grant run by the US Department of Health and Human Services, but you never apply to HHS. The money flows to your state, and your state hands intake to local agencies (more on that below). What it covers:

• Regular benefit: a payment toward your heating or cooling bill, usually sent directly to the utility. Across the 546 LIHEAP listings in our directory that publish a dollar cap, the median is $1,000, and most states scale the benefit by household size, income, and fuel type.
• Crisis assistance: if you have a shutoff notice or you are out of heating fuel, the crisis component can move within days instead of weeks. This is the part to ask for by name when the situation is urgent.
• Furnace repair or replacement: many states use LIHEAP funds to fix or replace a dead heating system. Not every state does this, so ask your local agency directly.

Income limits: federal rules let each state set its cutoff between 110 percent of the federal poverty line and the greater of 150 percent of poverty or 60 percent of state median income. Most states sit near the top of that range, and many grant automatic eligibility if anyone in your household already receives SNAP, SSI, or TANF. If your income is above roughly 150 percent of poverty in a low-cutoff state, you will likely be denied LIHEAP, but keep reading, because the utility rebate section probably still applies to you.

Timing matters. LIHEAP is funded annually and many states open applications in fall for heating help (and some open summer rounds for cooling). Funds can run out before the season ends. Apply when the window opens, not when the bill becomes unpayable.

We track 630 LIHEAP listings across 604 cities in our directory, each linking to the right state page. Your state's version may be called something else entirely (HEAP in New York, EAP in Indiana, CEAP in Texas), which is one more reason people fail to find it.

Weatherization: the actual free upgrade

The Weatherization Assistance Program is run by the Department of Energy and is the closest thing in America to a free home renovation, within a specific scope: making your house cheaper to heat and cool. A typical job includes attic and wall insulation, air sealing, duct sealing, and health and safety work like carbon monoxide detectors and combustion testing. Where the heating system is unsafe or shot, the crew can often repair or replace it.

This is not a small or obscure program. Our directory holds 6,257 weatherization listings, and 2,202 of our 2,203 live cities have at least one. Among the 4,967 weatherization listings that publish a dollar cap, the median is $8,000 per home, and the high end goes well past that:

• Lynn, Massachusetts: Mass Save income-eligible weatherization, up to $25,000 in no-cost upgrades.
• Washington, DC: the DC Weatherization Assistance Program runs up to $25,000 per home.
• Chicago: the Illinois Home Weatherization Assistance Program covers up to $16,000 per household, plus $3,500 for health and safety work.
• Newark, New Jersey: NJ Comfort Partners delivers up to $14,000 in upgrades plus $2,500 in health and safety measures at no cost.

Who qualifies: income at or below 200 percent of the federal poverty line in most states (some use 60 percent of state median income instead, whichever the state elected). Here is the connection most articles miss: in most states, already receiving LIHEAP makes you automatically income-eligible for weatherization. The LIHEAP approval letter does the income paperwork for you, and many agencies give LIHEAP households priority on the list. That is why the order of operations at the bottom of this guide starts with LIHEAP even if bill help is not your main goal.

Who does not qualify, plainly:

• Households above the income cutoff. There is no full-price version of WAP; if you are over the line, your path is utility rebates and tax credits instead.
• Homes that already went through weatherization once. A previously weatherized home is generally not eligible for a second round, even decades later, with narrow exceptions.
• Homes in bad structural shape, for now. If the roof leaks, the wiring is dangerous, or there is serious mold, the agency will often defer the job until those problems are fixed, because blowing insulation into a wet attic makes things worse. If that is your situation, fix the underlying problem first, and yes, there are grants for that too: see our guide to free roof replacement grants.

About the waitlist: it is real, it is often months long, and it is still worth joining today. The list moves in batches as funding cycles land, priority households (seniors, disabled residents, families with young children, highest energy burden) get pulled forward, and you lose nothing by being on it while you do the utility rebate steps below. People talk themselves out of thousands of dollars of free work because a waitlist sounds indefinite. Join the list.

Utility rebates: faster, smaller, and mostly not income-gated

The third system is not government money at all. State regulators require most utilities to fund efficiency programs, and the result is rebates on specific equipment: heat pumps, insulation, smart thermostats, heat pump water heaters, window upgrades. Two facts from our dataset that surprise people:

• Rebate programs are everywhere. We track 8,382 rebate listings across 2,197 of our 2,203 cities. Wherever you live, your utility almost certainly runs at least one.
• They are mostly open to everyone. 8,190 of those 8,382 rebate listings (98 percent) carry no income requirement at all. If LIHEAP and WAP turned you down on income, this is the lane that is still open.

The median listed rebate cap in our dataset is $800, which tells you the honest scale: most rebates are hundreds of dollars per item, not a free furnace. The exception is heat pumps, where utilities and state energy offices have gotten aggressive. We track 2,837 heat pump incentive listings across 2,058 cities, and the top of the range is serious money: Schenectady, New York customers can get up to $15,000 through National Grid's heat pump rebate program, and Rockville, Maryland homeowners can stack Pepco EmPOWER rebates up to $10,500. Browse the full energy category for your area on our energy programs page or the HVAC page if the heating system itself is the project.

Two warnings before you buy anything:

• Many rebates require pre-approval or a participating contractor. Buying the heat pump first and asking for the rebate second is the classic way to lose it. Read the program page before you sign a contract.
• Rebates come in two flavors: instant (the contractor or store takes it off the invoice) and mail-in (you file paperwork and wait for a check). Instant is better when offered; mail-in rebates get forgotten in junk drawers nationwide.

One more thing in this lane: the federal Inflation Reduction Act created two big rebate programs, HEAR (electrification rebates) and HOMES (whole-home efficiency rebates), run by the Department of Energy through each state. They launched state by state, which means your state may be fully live, partially live, or still building its program. We will not pretend to know your state's status from a national page; check your city on our energy grants page, where live programs show up as they open.

The part nobody explains: where you actually apply

Community action agencies are local nonprofits, one covering nearly every county in the country, that administer LIHEAP, weatherization, and usually a stack of other assistance programs. Finding yours takes five minutes:

1. Search "[your state] LIHEAP" and click the .gov result. Every state energy assistance page lists its local intake agencies by county. The federal LIHEAP page also links every state office.
2. Or dial 211. The United Way's referral line knows exactly which agency covers your address and what its current intake status is. This is often faster than the internet.
3. Or check your city on The Grant Map. Every LIHEAP and weatherization listing in our directory links to the official application page for that area. Find your city and look under energy assistance.

What to have ready when you call or apply: photo ID, proof of income for everyone in the household for the last 30 to 90 days (pay stubs, Social Security award letters, unemployment statements), your most recent utility bills, and proof you live there (the bill usually covers this). Renters should also have the landlord's contact information. Having the documents ready on the first contact routinely saves weeks, because incomplete applications go to the bottom of the pile.

What the weatherization audit visit actually looks like

People skip weatherization because they imagine an invasive inspection or a sales pitch. Here is the real sequence so there are no surprises:

1. The energy audit (2 to 4 hours). An auditor from the agency walks the whole house: attic, basement or crawlspace, furnace, water heater. The signature test is the blower door, a fan mounted in your front door frame that depressurizes the house so instruments can measure exactly how leaky it is. Many auditors also use an infrared camera to spot missing insulation, and they run combustion safety tests on gas appliances. You pay nothing.
2. The work order. The audit software ranks every possible improvement by cost effectiveness, and the measures that clear the bar become the job. You see the list before anything happens.
3. The crew visit (usually 1 to 3 days). Insulation, air sealing, duct work, and whatever health and safety items the audit flagged. These are agency crews or contracted installers, not salespeople; nothing is offered for purchase.
4. The final inspection. A quality inspector (not the crew) verifies the work, often re-running the blower door to document the improvement. Then the file closes and you keep the savings.

Renting? You can still get this

Both LIHEAP and weatherization serve renters, not just homeowners. LIHEAP is straightforward: if the energy bill is in your name (or heat is included in rent in some states' rules), you apply like anyone else. Weatherization needs one extra ingredient: written landlord consent, since crews will be modifying the building. Two things worth knowing:

• Many states require the landlord to sign an agreement not to raise the rent because of the improvements for a set period, which protects you from paying for your own free upgrade.
• Some states ask landlords to contribute a share of the cost on rental units. That is between the agency and the landlord, not you.

The practical move: get your landlord's verbal yes before you apply, so the consent form does not stall the file later. Most landlords sign, because free insulation raises the value of their building. For more programs open to tenants, see our renter programs page.

The right order of operations

Done in the right sequence, each program unlocks the next. Done out of order, you leave money on the table or buy equipment a free program would have covered.

1. Apply for LIHEAP first, even if the bill is not your biggest problem. The approval does your income verification for weatherization in most states and often moves you up the priority list. If you are in crisis (shutoff notice, no heat), say so; the crisis track is faster.
2. Get on the weatherization waitlist the same week. Ask the same agency, it is usually the same office and sometimes the same form. Then forget about it while the list moves; you have done your part.
3. While you wait, claim utility rebates for anything WAP will not cover. Smart thermostats, appliance rebates, heat pump incentives if your system dies before the waitlist clears. Check rebate terms before buying anything, and check whether your state's HEAR or HOMES rebates have gone live on our energy page.
4. If the audit defers your home for a leaking roof or bad wiring, pivot to repair grants for the blocking problem, then get back on the weatherization list. Start with our guides to roof replacement grants and, if you are 62 or older, senior home repair grants.

Seniors get one more layer: most states pull older residents forward on the weatherization priority list, and separate senior repair programs can fix the deferral problems. Our seniors page and low income page collect those by city. And if your income is very low and your house needs more than energy work, the USDA Section 504 program (up to $10,000 in grant funds for homeowners 62 and older in eligible rural areas) stacks with all of this; we covered it in detail in the $10,000 home improvement grant guide.

Common questions

Is weatherization really free, or is there a catch?

For income-qualified households, the work is genuinely free: no payment, no lien, no repayment if you sell. The honest catches are the waitlist, the income limit, and the deferral rule for homes with serious unresolved problems. Nobody from a real weatherization agency will ever ask you for a credit card.

How long is the weatherization waitlist?

It varies by agency and funding cycle, from a couple of months to over a year. Priority status (senior, disabled, young children in the home, very high energy bills relative to income) moves you up. The only guaranteed way to wait forever is to never join the list.

My income is just over the limit. Is there anything for me?

Yes. Utility rebates are the main lane: 98 percent of the rebate listings in our directory have no income test. Federal efficiency tax credits also have no income cap. And some states set LIHEAP at 60 percent of state median income, which is higher than people assume, so check your state's actual number before ruling yourself out.

Will LIHEAP pay for new windows or insulation?

No. LIHEAP is bill help, crisis help, and in many states furnace repair. Insulation, air sealing, and window work belong to weatherization and utility rebate programs. This mix-up is the single most common reason people think they were denied something they never actually applied for.
