Millions of low-income households struggle with high utility bills every year. Weatherization Assistance Grants help eligible families reduce energy costs by making homes more energy efficient at no cost to the homeowner or tenant. These grants are funded by the federal government and administered through state and local agencies, allowing qualified households to receive improvements such as insulation, air sealing, heating system repairs, and energy-efficient upgrades.
This guide explains how the Weatherization Assistance Program works, who qualifies, what services are covered, how to apply, and where to find official assistance.
What Are Weatherization Assistance Grants?
Weatherization Assistance Grants provide funding that helps improve the energy efficiency, health, and safety of homes occupied by low-income households. These grants are primarily distributed through the Weatherization Assistance Program (WAP), which is funded by the U.S. Department of Energy (DOE).
The program focuses on reducing energy waste, lowering utility bills, and making homes safer and more comfortable throughout the year.
Unlike loans, these grants do not need to be repaid. Qualified households receive weatherization services performed by trained professionals through local weatherization agencies.

Purpose of the Weatherization Assistance Program
The Weatherization Assistance Program was established to help vulnerable households reduce their energy burden while improving housing quality.
The program aims to:
- Lower monthly heating and cooling costs
- Increase home comfort
- Improve indoor air quality
- Reduce energy consumption
- Enhance home safety
- Extend the life of heating and cooling systems
- Reduce greenhouse gas emissions
Since its creation, millions of American homes have received weatherization improvements.
Who Qualifies for Weatherization Assistance Grants?
Eligibility depends on federal guidelines and additional state requirements. While each state administers the program differently, several groups generally receive priority.
Income Requirements
Most applicants must have household income that falls within limits established by their state.
Many states use:
- 200% of the Federal Poverty Guidelines
- 60% of State Median Income
Applicants should verify current income limits through their state weatherization office.
Priority Households
Although anyone meeting income requirements may qualify, priority is often given to:
- Older adults
- Individuals with disabilities
- Families with young children
- Veterans
- Households with extremely high energy costs
- Residents living in unsafe or inefficient homes
Automatic Eligibility
In many states, households participating in certain federal assistance programs may automatically qualify or receive expedited eligibility.
Examples include:
- Supplemental Security Income (SSI)
- Temporary Assistance for Needy Families (TANF)
- Low Income Home Energy Assistance Program (LIHEAP)
- Certain tribal assistance programs
Requirements vary by state.
What Services Do Weatherization Grants Cover?
The Weatherization Assistance Program does not simply replace old appliances. Instead, trained energy auditors inspect the home and recommend improvements that provide the greatest energy savings.
Common services include:
Home Energy Audit
Before any work begins, certified professionals conduct an energy assessment that may include:
- Blower door testing
- Infrared scanning
- Heating system inspection
- Air leakage testing
- Safety inspection
This audit determines which improvements will provide the best results.
Insulation Installation
Proper insulation significantly reduces heat loss during winter and heat gain during summer.
Weatherization grants may pay for:
- Attic insulation
- Wall insulation
- Basement insulation
- Floor insulation
- Crawlspace insulation
Air Sealing
Small air leaks around windows, doors, pipes, and electrical outlets can dramatically increase energy costs.
Weatherization crews seal these leaks using professional materials such as:
- Caulk
- Weatherstripping
- Foam sealants
- Door sweeps
Heating System Repairs
Older heating systems often waste energy.
Depending on inspection results, the program may cover:
- Furnace repair
- Furnace replacement
- Boiler repair
- Boiler replacement
- Thermostat upgrades
- Heating system tune-ups
Replacement only occurs when repairs are not cost-effective.
Cooling System Improvements
Some states provide assistance for cooling equipment where climate conditions justify the expense.
Services may include:
- Air conditioner repair
- Air conditioner replacement
- Ventilation improvements
Availability depends on funding and local guidelines.
Water Heater Improvements
Eligible households may receive:
- Water heater insulation
- Pipe insulation
- Water heater repair
- Water heater replacement
These improvements help reduce water heating costs.
Ventilation Improvements
Proper ventilation helps improve indoor air quality.
Weatherization work may include:
- Bathroom exhaust fans
- Kitchen ventilation
- Attic ventilation improvements
Health and Safety Repairs
The program also addresses issues that affect occupant safety.
Possible improvements include:
- Carbon monoxide detector installation
- Smoke alarms
- Minor electrical repairs
- Gas leak correction
- Combustion appliance testing
