If you can’t afford an air conditioner, the most reliable way to get one for free is through the Low Income Home Energy Assistance Program (LIHEAP), which in many states will provide a window or portable unit to qualifying households. The Weatherization Assistance Program can replace a broken cooling system, medical-necessity programs prioritize people whose health conditions make heat dangerous, and local charities and utility hardship funds distribute units during summer. All of these paths start with the same phone call: your local Community Action Agency, or 211.
Who Qualifies
Two things determine whether you can get a free air conditioner: your income, and in many programs, whether someone in your household is especially vulnerable to heat.
For LIHEAP, federal law caps eligibility at 150 percent of the federal poverty guidelines or 60 percent of your state’s median income, whichever is higher.1Office of the Law Revision Counsel. 42 USC 8624 – Applications and Requirements For 2026, 100 percent of the poverty level in the 48 contiguous states is $15,960 for one person and $33,000 for a family of four, so a common 150 percent threshold works out to roughly $23,940 and $49,500.2HHS ASPE. 2026 Poverty Guidelines – 48 Contiguous States Alaska and Hawaii use higher figures. States set their own thresholds within that ceiling.
Eligibility for an actual unit, rather than bill-payment help, usually requires an additional factor: a household member over 65, a child under six, or a documented medical condition made worse by heat.
LIHEAP Cooling Units
LIHEAP is a federal block grant, so each state designs its own program.3The LIHEAP Clearinghouse. State and Territorial Programs Some states use their cooling dollars only to help pay summer electric bills. Others buy and deliver window air conditioning units to qualifying homes. Whether you can get a physical unit depends entirely on where you live, which is the first thing to confirm when you call.
If your state does provide units, priority typically goes to households with older adults, young children, or someone whose health is at risk in the heat. Even in states that lean toward bill payment, an emergency medical situation can sometimes unlock equipment assistance that isn’t advertised.
Weatherization Assistance Program
The Weatherization Assistance Program (WAP) works differently. Instead of handing you a window unit, it sends technicians to fix the home. The federal statute explicitly covers “cooling efficiency modifications, including replacement air-conditioners, ventilation equipment, screening, window films, and shading devices.”4Office of the Law Revision Counsel. 42 USC 6862 – Definitions If your central system is broken or dangerously inefficient, WAP can replace it at no cost to you.
Income eligibility is more generous than LIHEAP. You qualify if your household income is at or below 200 percent of the federal poverty guidelines, and you qualify automatically if you already receive LIHEAP, SSI, or TANF.4Office of the Law Revision Counsel. 42 USC 6862 – Definitions
The catch is time. WAP has limited funding and long waitlists in many areas, so it works as a long-term fix rather than an emergency one. When you do get to the top of the list, the work usually includes insulation and duct sealing alongside any cooling upgrade, which lowers your bill every month afterward.
Medical Necessity Programs
When heat is a direct medical danger, a separate set of programs run through health departments, Medicaid managed-care plans, and LIHEAP subprograms can provide a unit faster. Qualifying conditions generally fall into two groups: illnesses that get worse in heat, such as cardiovascular disease, COPD, asthma, chronic kidney disease, and certain psychiatric conditions; and conditions that impair the body’s ability to cool itself, including spinal cord injuries, multiple sclerosis, ALS, cerebral palsy, and autonomic neuropathy.
The doctor’s letter is what unlocks these programs, and it has to do more than list a diagnosis. It needs to state that a climate-controlled environment is part of your treatment plan and that going without air conditioning would seriously worsen your condition or put your life at risk. Some programs also want documentation of past heat-related emergency visits or hospitalizations. If you need a portable rather than a window unit, the letter should explain why.
Get the letter written before summer. These programs run out of inventory quickly once temperatures climb.
Charities and Utility Hardship Funds
Private organizations often move faster than government programs. The Salvation Army and the Society of St. Vincent de Paul run seasonal drives that distribute fans and window units in many communities. Area Agencies on Aging focus on older adults who may need help navigating the paperwork.
Many utility companies also maintain hardship funds, sometimes underwritten by voluntary contributions from other customers. These can pay for a unit or offset summer bills. They’re often not advertised, so call your utility directly and ask about low-income cooling programs.
Charitable programs work first-come, first-served with limited stock. Calling in late June, when temperatures are already dangerous, puts you in line behind everyone else in the same situation. Reach out in the spring if you can.
How to Apply
LIHEAP and WAP applications go through your local Community Action Agency. Find yours through the LIHEAP Clearinghouse or by dialing 211, which connects to local social services in most areas. Some agencies take applications online; others require an in-person visit or mailed forms.
Gather these documents before you start:
- Proof of income for everyone in the household, usually covering the past 30 days: pay stubs, Social Security award letters, pension statements, or unemployment documentation.
- Identification for each person in the home, such as a driver’s license, state ID, or birth certificate.
- A recent utility bill showing service at your current address.
- A doctor’s letter, if you’re applying through a medical-necessity pathway.
- Written landlord permission, if you rent. This is one of the most common causes of delay, so get it in advance.
Accuracy matters. Mismatched names, missing household members, or income figures that don’t match your documents will slow the process or trigger a denial.
Standard LIHEAP applications can take up to 30 business days. If your power has been shut off, you have a disconnection notice, or someone in the household has a heat-sensitive medical condition, say so when you apply. Emergency or crisis applications are typically processed in 48 to 72 hours. Once approved, some agencies require you to pick up a window unit from a distribution center, so plan for transportation of equipment that can weigh 40 to 60 pounds. WAP work and central-system repairs are scheduled with a technician who handles installation.
Renters: Landlord Permission and Your Rights
Most cooling programs require your landlord’s written consent before installing a window or portable unit. Ask early. A landlord who won’t respond can stall an otherwise complete application.
If your disability makes air conditioning medically necessary and the landlord refuses, federal law may be on your side. Under the Fair Housing Act, a landlord cannot refuse to let you make reasonable modifications to your unit at your own expense when those modifications are necessary because of a disability, though the landlord can require you to restore the unit when you move out.5Office of the Law Revision Counsel. 42 USC 3604 – Discrimination in the Sale or Rental of Housing The landlord also has to make reasonable accommodations in rules and policies so that a person with a disability has equal opportunity to use the dwelling.
If your request is denied, you can file a housing discrimination complaint through HUD’s online portal.6U.S. Department of Housing and Urban Development. HUD-903 Report Housing Discrimination Your doctor’s documentation strengthens the complaint.
Running Costs After You Get the Unit
A free air conditioner still costs money to run, and the electricity is on you. A standard 8,000 BTU window unit running eight hours a day adds roughly $27 to $35 a month to your electric bill, using the national average residential rate of about 17.5 cents per kilowatt-hour as of early 2026.7U.S. Energy Information Administration.

LIHEAP can help with the higher summer bill, not just the equipment. When you apply for a cooling unit, ask the Community Action Agency whether you’re also eligible for bill-payment assistance during the cooling season. Many utilities also offer discounted rates or budget billing for low-income customers.
One call gets most of this started. Your local Community Action Agency, or 211, can tell you whether your state’s LIHEAP program provides physical units, screen you for income eligibility, and connect you to the medical-necessity programs and charities in your area. If heat is a documented health risk for you, get the doctor’s letter written now. Inventory disappears fast once summer arrives.
