LIHEAP (the Low Income Home Energy Assistance Program) cuts your winter heating bill more in dollar terms, but only if you qualify for it — DIY fixes are smaller but available to everyone. A LIHEAP grant often runs several hundred dollars, while free or cheap DIY steps typically save a percentage of your existing bill.
The two aren't really competing options. LIHEAP is a cash subsidy restricted by income, and DIY weatherization is a set of free or low-cost actions any household can take regardless of what they earn. Understanding how each one actually works shows why most readers should be asking how to use both together, not which one to pick.

What DIY heating savings actually look like
The two biggest DIY levers are your thermostat and your air leaks, and both are backed by federal guidance. DOE's Energy Saver program states that setting your thermostat back 7–10°F for eight hours a day can cut heating and cooling costs by up to 10% annually, with no spending required. That's a schedule change — lower the temperature while you sleep or are at work, and raise it when you're home and awake. Sealing air leaks costs a little more but still qualifies as DIY.
Nevada's Public Utilities Commission, citing DOE data, reports that caulk and weatherstripping cost about $5 to $10 and roughly an hour of labor, and can cut a home's total energy bill by 5–10%. Together, a thermostat setback and basic air sealing are the two highest-leverage, lowest-cost moves available to any household, rich or poor. The catch is that these are percentage savings, so the dollar amount depends on your existing bill. A household heating with natural gas and a household heating with electricity will see very different payoffs from the identical DIY steps, which matters when you're comparing them against a fixed LIHEAP grant.
What LIHEAP actually pays, and who qualifies
LIHEAP is a federally funded program that sends money directly toward a household's energy costs, but it's not open to everyone. HHS's Administration for Children and Families caps eligibility at 150% of the federal poverty guidelines, or 60% of state median income if that's higher, with a floor at 110% of poverty. In other words, you have to be lower-income to receive it at all — DIY fixes have no such restriction. The amount you'd actually receive is fixed by your income tier, not by how much fuel you use. North Carolina's FY2026 LIHEAP schedule pays a flat $400 to households at 0–50% of poverty and $300 to those at 51–100% — the same payment whether your home is drafty or tight, large or small.
Nevada's program works similarly in substance: HHS's FY2024 executive summary for Nevada found the grant covered 62.7% of the average recipient's energy bill, rising to 70.3% for the households with the highest energy burden — a real but partial offset, not a full bill payment. Funding is also limited at the national level. Congress funded LIHEAP at roughly $4.05 billion for FY2026, a modest increase over FY2025, after the White House's budget had proposed eliminating the program outright. That funding doesn't stretch to cover everyone who qualifies: NEADA data cited by U.S. senators shows LIHEAP typically reaches only about one in six income-eligible households nationwide in a given year. Most people who qualify on paper get no payment at all in a given winter.
Doing the math — which one saves more money?
This winter's forecast bills set up a direct comparison. EIA's October 2026 Winter Fuels Outlook projects the average natural-gas-heated home will spend about $640 this winter, down 9% from last year, while the average electrically-heated home will spend about $1,196, up 4%. Heating-oil households are forecast to pay roughly 21% more than last year. Applying DOE's 5–10% DIY savings range to those bills gives a concrete dollar figure.
On a $640 gas bill, that's roughly $32 to $64 saved. On a $1,196 electric bill, it's roughly $60 to $120. Those are real savings, but they're modest compared with what an eligible household can get from LIHEAP — North Carolina's and Nevada's figures put a typical grant in the several-hundred-dollar range, often covering well over half of a recipient's bill. So for an income-eligible household, LIHEAP usually wins on raw dollars, and by a wide margin. For a household that doesn't qualify, or qualifies but doesn't get funded given the one-in-six reach cited above, DIY fixes are the only lever available — and they're worth pulling regardless of income, since they cost little or nothing and work on top of whatever subsidy you do or don't receive.
How to use both together
These two options aren't mutually exclusive, and treating them that way leaves savings on the table. A LIHEAP grant doesn't change how much heat escapes through an unsealed window, and a sealed window doesn't reduce what LIHEAP will pay toward your bill.
Stacking them captures both kinds of savings at once. Practical order of operations for this winter: A household heating with electricity has more to gain from DIY sealing and setback habits in raw dollars than one heating with gas, simply because the underlying bill is larger — about $1,196 versus $640 this winter, per EIA's forecast. That's worth factoring in before assuming any single fix pays off the same way for every home.
- Check your eligibility against the 150%-of-poverty (or 60%-of-state-median-income) threshold and apply for LIHEAP if you're close to or under it — a denial costs you nothing but time.
- Set your thermostat back 7–10°F for the eight hours you're asleep or away, at no cost, per DOE's guidance.
- Spend the $5–$10 on caulk and weatherstripping for obvious drafts around windows, doors, and outlets — an hour of labor for a 5–10% cut to your total energy bill.
- If you receive a LIHEAP grant, remember it's calculated to cover a portion of your bill, not all of it (62.7% on average in Nevada's data), so the DIY savings still matter even after the subsidy lands.
- If you apply for LIHEAP and don't receive funding, given the program typically reaches only one in six eligible households, treat the DIY steps as your primary lever rather than a backup plan.
