A Comprehensive Guide to Government Assistance For AC

If you can't afford a new AC unit, or your central heat and air system needs replacing just as the weather turns, you have more options than paying the full price up front. Government programs such as the Weatherization Assistance Program can repair or replace heating and cooling systems for eligible households at no cost, energy assistance can help with bills and emergencies, and many HVAC companies offer financing and payment plans. Here's how each option works, who qualifies, and what to do first.

First: Repair or Replace?

Before you look for help, find out what you actually need. Ask a licensed HVAC contractor to diagnose the problem and give you written prices for both a repair and a replacement. A repair may be enough if the system is fairly young and the fix is minor. Replacement often makes more sense when the system is old, needs a major part such as a compressor, or breaks down repeatedly. Having that written estimate also helps when you apply for assistance.

Government Programs That Can Help

Weatherization Assistance Program (WAP)

The federal Weatherization Assistance Program, run locally by community agencies, makes homes more energy efficient at no cost to eligible households. Upgrades can include insulation, air sealing, and, when needed, repair or replacement of heating and cooling systems. The program averages about $6,500 in upgrades per home.

Who qualifies: eligibility is based on household income, and households with older adults, people with disabilities, or children are often given priority. Renters can qualify with the landlord's permission.
How to apply: contact your state's weatherization office or local community action agency. Expect a waiting list in many areas.

Low Income Home Energy Assistance Program (LIHEAP)

LIHEAP helps eligible households pay heating and cooling bills, and many states also use it for energy emergencies. In some states, LIHEAP or its crisis component can help repair or replace a broken furnace, heat pump, or air conditioner. Rules, benefit amounts, and application dates vary by state.

Funding status: LIHEAP was fully funded for fiscal year 2026 at about $4.05 billion, and all of that money has been released to the states. For the 2026-27 season, Congress has so far funded the program only temporarily, and the administration has proposed eliminating it for fiscal year 2027, so apply as early as your state allows.
When to apply: most states open heating applications in October or November, and some programs close when funds run out.
How to apply: through your state LIHEAP office or local community action agency.

State, Utility, and Local Programs

Utility low-income programs: many electric and gas utilities run free or discounted efficiency programs, and some offer equipment replacement for qualifying customers. Call the number on your bill and ask.
Utility rebates: rebates for efficient heat pumps and air conditioners can lower the price of a new system. Some utilities also offer on-bill financing, letting you repay the cost through your monthly bill.
City and county home repair programs: many local governments use federal housing funds for emergency home repairs, including heating and cooling, for low-income owners.
USDA home repair help: in rural areas, the USDA's Section 504 program offers low-interest repair loans and, for very low-income homeowners 62 and older, repair grants.
Area Agencies on Aging: older adults can ask their local agency about home repair and energy help.
Veterans: some VA and state veterans programs help with home repairs; see our guide to housing assistance programs for veterans.

A note on tax credits: the federal Energy Efficient Home Improvement Credit, which covered part of the cost of efficient heat pumps and air conditioners, ended for equipment placed in service after December 31, 2025. Be cautious of any contractor still promising that federal credit for a new installation.

HVAC Financing and Payment Plans

If you don't qualify for assistance, or need a new system faster than a program can deliver, financing can spread the cost out:

Contractor financing: many HVAC companies offer payment plans through lending partners, sometimes with promotional 0% periods. Read what happens when the promotion ends; deferred interest can be expensive.
Utility on-bill financing: where available, often at low or no interest.
Credit union or personal loans: compare the APR and total cost with the contractor's offer.
Lease and rent-to-own plans: lower up-front cost, but usually more expensive in total. See our guides to flexible payment plans for heat pumps and pay-monthly heat pumps.
"No credit check" or "guaranteed approval" offers: these exist, but they often come with high fees or interest. Get the total cost in writing before you sign.

How to Get a Fair Price on a Replacement

Get at least three written quotes from licensed, insured contractors for the same size and type of system.
Ask for a load calculation rather than sizing by square footage alone; an oversized system costs more and works worse.
Consider a heat pump, which both heats and cools and may qualify for utility rebates.
Ask about equipment and labor warranties, and get them in writing.
Avoid anyone who pressures you to sign that day or asks for full payment up front.

What to Do This Week

Get a written diagnosis and repair-versus-replace estimate.
Call your local community action agency about weatherization and LIHEAP, and ask about emergency help if you're without heat or cooling.
Call your utility about low-income programs, rebates, and on-bill financing.
If you're 62 or older, call your Area Agency on Aging; in rural areas, ask about USDA repair help.
If you'll finance, compare at least two offers on total cost, not monthly payment.

If your home needs other repairs too, see our guides to window replacement grants for seniors and roof repair grants and assistance.

The Bottom Line

If you can't afford a new AC unit or heating system, start with a written estimate, then check free help first: the Weatherization Assistance Program, LIHEAP, and your utility's programs. If you need to move faster or don't qualify, compare HVAC financing and payment plans on total cost. With heating season underway and federal energy assistance funding uncertain for next year, it's worth applying early.
