Key takeaways
- The Weatherization Assistance Program (WAP) can fully replace an inefficient or broken HVAC system when it's the most cost-effective fix identified by a home energy audit.
- LIHEAP's crisis component specifically funds emergency furnace repair or replacement in many states, separate from its regular monthly bill assistance.
- USDA Section 504 grants (up to $10,000 for homeowners 62+) can cover HVAC replacement as part of a broader health-and-safety repair.
- Seniors get automatic priority in WAP and LIHEAP when funding is limited — always mention age when you apply.

Weatherization Assistance Program
WAP is a federally funded, state-run program that makes homes more energy efficient at no cost to eligible households — and when a home energy audit determines that replacing an inefficient furnace or AC unit is the most cost-effective improvement, WAP can cover full replacement, not just minor repairs. Eligibility is based on income at or below 200% of the Federal Poverty Level (roughly $31,920 for a single person, $66,000 for a family of four, current figures), and households already receiving SNAP, TANF, SSI, or LIHEAP typically qualify automatically. Seniors and people with disabilities receive priority when funding is limited. Find your state's WAP office through the Department of Energy's WAP locator, or see our utility relief guide for the fuller picture.
LIHEAP crisis assistance
Beyond its regular monthly bill assistance, LIHEAP includes a crisis component in many states specifically for emergency situations — a broken furnace in winter, for instance — that can fund repair or replacement faster than the standard application track. Contact your state LIHEAP office directly and specifically ask about crisis or emergency funding rather than only the standard benefit, since the two tracks often have different processes and timelines.
USDA Section 504 for homeowners
For rural homeowners age 62 and older with very low income, USDA Section 504 grants (up to $10,000, forgiven after three years in the home) can fund HVAC replacement as part of a broader health-and-safety repair, and can be combined with a 1% loan up to $40,000 for larger projects. See our home modification grants guide for the fuller breakdown of how Section 504 works, since the same program covers both bathroom and HVAC-related repairs.
Local and utility company help
Two more sources worth checking directly: your local Area Agency on Aging often knows about county or nonprofit HVAC repair funds that aren't listed nationally — find yours through the Eldercare Locator. And many utility companies run their own senior or low-income repair assistance programs separate from LIHEAP — call your utility directly and ask specifically about hardship or senior repair programs, since these are rarely advertised prominently.

Frequently asked questions
Can I get a broken furnace replaced for free?
Potentially yes, through the Weatherization Assistance Program (if replacement is the most cost-effective fix per an energy audit), LIHEAP crisis funds in many states, or USDA Section 504 grants for eligible rural senior homeowners.
What income qualifies for HVAC assistance programs?
Weatherization uses 200% of the Federal Poverty Level as its main threshold; LIHEAP eligibility varies by state; USDA Section 504 requires very-low-income status (roughly 50% of area median income) for rural homeowners.
Do I need to already receive other benefits to qualify?
No, but it helps — households already receiving SNAP, TANF, SSI, or LIHEAP typically qualify automatically for weatherization without a separate income review.
What if I need help right now, not after a standard application?
Ask your state LIHEAP office specifically about crisis or emergency assistance, which often moves faster than the standard track for situations like a broken furnace in winter.
