Where to find money for energy-efficient upgrades when your budget is tight

If you rent or own a home on a limited income, energy bills can take a chunk of money you need elsewhere. The good news: federal and state programs pay for some upgrades that lower those bills, and many cost you nothing upfront. The catch is that programs vary by state, by income level, and by whether you own or rent — so what works in one place may not work in another.

The main sources of funding are the Weatherization Assistance Program (WAP), run by the Department of Energy through your state; utility company rebates, which differ by provider; and state-level efficiency programs. Some cover the full cost of work. Others require you to pay part of it. Most send a contractor to your home, do the work, and leave. You do not apply for a loan or pay anything back.

Key Takeaways

  • The Weatherization Assistance Program covers insulation, air sealing, and heating system repairs at no cost to homeowners who meet income limits, which vary by state but are usually around 200% of the federal poverty line.
  • Your utility company may offer rebates for specific upgrades like heat pump installation or window replacement, and these rebates stack with government programs.
  • Renters can request that landlords make improvements, and some programs will work directly with landlords to cover the cost.
  • The first step is to contact your state's WAP office or call 211 to find what programs operate in your area and whether you meet the income requirements.
  • Work is usually free or low-cost, but wait times can be several months because demand is high and funding is limited.

The Weatherization Assistance Program: what it covers and how to reach it

WAP is the largest federal program for energy upgrades in low-income homes. It pays for insulation in attics and walls, air sealing around doors and windows, heating system repairs or replacement, water heater upgrades, and sometimes heat pump installation. The program is free to homeowners who fall below the income limit — usually around 200% of the federal poverty line, though this varies by state. For a family of four in 2024, that is roughly $60,000 per year, but check your state's specific number because it changes.

To find your state's WAP office, go to the Department of Energy website and search for your state, or call 211 and ask for Weatherization. The office will tell you the income limit, what paperwork you need (usually proof of income and proof of residency), and how long the wait is. Many states have a waiting list because demand exceeds funding. Some prioritize households with elderly people, children, or people with disabilities.

Once you are accepted, an energy auditor visits your home, identifies where heat is escaping, and creates a work plan. Contractors then do the work at no cost to you. The whole process — from application to finished work — typically takes two to six months, sometimes longer.

Utility company rebates and what they actually pay for

Your electric or gas company may offer rebates for specific upgrades. These are separate from government programs and often stack with them, meaning you can use both. Common rebates cover heat pump installation, air conditioning replacement, insulation, weatherstripping, and sometimes smart thermostats.

The amount varies widely. Some utilities rebate $500 toward a heat pump; others cover $2,000 or more. Some require you to use a contractor from their approved list; others let you choose. The best way to find out what your utility offers is to call the customer service number on your bill and ask about energy efficiency rebates, or visit their website and search "rebates" or "efficiency programs."

Keep in mind that utility rebates often require you to pay upfront and then submit a receipt for reimbursement. If that is not possible for you, ask whether the utility can pay the contractor directly. Some will, especially for larger projects.

State and local programs beyond the federal baseline

Many states run their own efficiency programs on top of WAP. New York has the Clean Heat Program, which covers heat pump installation for low-income households. California has the Home Energy Renovation Assistance Program. Massachusetts offers rebates through MassSave. These programs differ in what they cover, income limits, and whether they require a contribution from you.

To find what your state offers, search "[your state] energy efficiency programs low income" or call 211. A 211 operator can tell you which programs are currently open in your area, what each one covers, and which one is the fastest route for your situation.

Some states also have programs specifically for renters. These usually work by having the program contact your landlord and offer to pay for improvements. Your landlord is not required to participate, but many do because the work is free to them.

Low-cost improvements you can do yourself while waiting for programs

If you are on a waiting list or do not meet the income limit for free programs, some upgrades are cheap enough to do yourself and still save money on bills. Weatherstripping around doors and windows costs $10 to $30 and can be installed in an afternoon. Caulk around window frames costs a few dollars. Pipe insulation for hot water pipes costs under $20 and reduces heat loss.

Programmable or smart thermostats cost $25 to $100 and can lower heating and cooling costs by 10% to 15% if you use them consistently. Window film or thermal curtains cost $20 to $50 per window and reduce heat loss in winter. Attic access covers and door sweeps are also inexpensive and effective.

These are not substitutes for professional work like insulation or air sealing, which require equipment and expertise. But they buy you time and reduce bills while you wait for a program to open up or while you save money for larger upgrades.

What happens if you rent and your landlord will not cooperate

Renters have fewer options than homeowners because the landlord controls the property. However, you have a few paths. First, ask your landlord to apply for a program like WAP or a state efficiency program. The work is free to them, and it increases the property value. Many landlords will agree once they understand there is no cost.

If your landlord refuses, check your state's tenant rights laws. Some states require landlords to maintain properties in a habitable condition, which includes adequate heating and insulation. If your home is genuinely cold or drafty in winter, you may be able to file a complaint with your local housing authority or health department. This is not a fast solution, but it creates a record and may pressure the landlord to act.

In the meantime, use the low-cost fixes listed above. You can install weatherstripping and caulk without damaging the property, and most landlords will not object. Ask permission before making any changes.

How to compare programs and choose the right one for your situation

If multiple programs operate in your area, the choice depends on what you need most and how long you can wait. WAP is usually free but has a waiting list. Utility rebates are faster but may require you to pay upfront. State programs fall somewhere in between.

Ask these questions when you contact each program: What is the income limit? What does the program cover? Is there a waiting list, and how long is it? Do I pay anything, or is it fully covered? Can the program pay the contractor directly, or do I pay and get reimbursed? Once you have answers, you can decide which program to pursue first.

If you are on a tight timeline — for example, winter is coming and your heating system is failing — prioritize programs that move fast and cover your specific need. If you have time and want the most comprehensive work done, WAP may be worth the wait.

Frequently Asked Questions

Do I have to own my home to get help with energy upgrades?

No. Homeowners can use WAP and most state programs. Renters can ask landlords to apply on their behalf, and some programs will work directly with landlords. If your landlord refuses, you have fewer options, but you can still use low-cost fixes like weatherstripping and thermal curtains.

What if my income is slightly above the limit?

Most programs have a hard income cutoff, but some have a higher limit for households with elderly people, children, or people with disabilities. Call your state's WAP office or 211 to ask whether an exception applies to you. If not, you may still be able to use utility rebates, which often have higher income limits or no limit at all.

How much money will I actually save on my energy bills?

Savings depend on your current home condition, your climate, and what work is done. Insulation and air sealing typically reduce heating and cooling costs by 10% to 30%. A heat pump can cut heating costs by 40% to 50% compared to electric resistance heat. Ask the energy auditor for an estimate before work begins.

Can I use multiple programs at the same time?

Yes. You can use WAP for insulation and air sealing, and then use a utility rebate for a heat pump. The programs coordinate so you do not pay twice for the same work. Tell each program about the others when you apply.

What if I have already paid for an upgrade — can I get reimbursed?

Most programs only pay for work done after you are accepted into the program. If you have already paid, you may be able to claim a rebate from your utility company if you have a receipt, but government programs usually will not reimburse past work. Ask before you spend money.
