Insulation Rebates 2026
Insulation and air sealing are eligible for up to $1,600 in HEAR rebates and play a critical role in whole-home energy efficiency. Better insulation reduces the workload on your heating and cooling system, and when combined with other upgrades, can help you qualify for larger HOMES program rebates based on total energy savings.

| HEAR | $1,600 | 80-150% AMI (50% of cost, up to cap) |
| HOMES | Up to $8,000 | Key component of whole-home energy savings approach |
| Weatherization Assistance (WAP) | Fully covered | ≤200% federal poverty level |

Insulation Rebates in 2026
The HEAR program allocates up to $1,600 for insulation, air sealing, and ventilation improvements. This is a combined category, so the $1,600 cap covers all weatherization work together rather than each type individually.
For households at or below 80% AMI, the full cost is covered up to $1,600. For households between 80-150% AMI, 50% of the cost is covered up to the cap. Given that attic insulation typically costs $1,500-$3,500 and wall insulation runs $2,000-$6,000, the rebate covers a meaningful portion of most projects.
Insulation is also one of the most impactful upgrades for the HOMES program. Since HOMES rebates are based on whole-home energy savings (up to $8,000 for low-income households), adding insulation can push your total home improvement past the energy savings thresholds needed to unlock larger rebates. Many energy auditors recommend insulation as the first step in any home performance upgrade.
Types of Insulation That Qualify
Several insulation methods qualify for the HEAR rebate. The right choice depends on your home's construction, existing insulation levels, and where the biggest air leaks are:
- Blown-in attic insulation: The most common and cost-effective upgrade. Cellulose or fiberglass is blown into the attic floor to reach R-38 to R-60 levels. Typical cost: $1,500-$3,000.
- Wall cavity insulation: Dense-pack cellulose or injection foam can be added to existing walls through small holes. Important for older homes with little or no wall insulation.
- Spray foam insulation: Open-cell or closed-cell spray foam provides both insulation and air sealing. More expensive but highly effective for rim joists, crawl spaces, and cathedral ceilings.
- Air sealing: Caulking, weatherstripping, and sealing around penetrations (pipes, wires, ducts) often delivers the highest return per dollar spent. Frequently done alongside insulation.
- Duct sealing and insulation: Leaky ductwork can waste 20-30% of conditioned air. Sealing and insulating ducts in unconditioned spaces significantly improves system efficiency.
A home energy audit can identify where insulation upgrades will have the greatest impact. Many state programs offer free or subsidized energy audits as part of the HEAR rollout.
Weatherization Assistance Programs
Beyond HEAR, the federal Weatherization Assistance Program (WAP) provides free insulation and energy efficiency improvements for low-income households. WAP has been operating for decades and received additional funding through the Inflation Reduction Act.
WAP eligibility is based on the federal poverty level rather than area median income. Households at or below 200% of the federal poverty level may qualify for fully funded weatherization services including insulation, air sealing, furnace repair or replacement, and other efficiency measures.
WAP services are delivered through a network of local community action agencies. Wait times can be long (months to over a year in some areas), but the work is done at no cost to qualifying households. Contact your state's WAP provider to apply.
If you qualify for both WAP and HEAR, you may be able to use both programs for different improvements. For example, WAP might cover insulation and air sealing while HEAR covers a heat pump installation. Coordination between programs varies by state, so ask your state energy office about how to maximize both.

Frequently Asked Questions
How much is the insulation rebate under HEAR?
The HEAR program provides up to $1,600 for insulation, air sealing, and ventilation combined. Households at or below 80% AMI get 100% of costs covered up to the cap. Households at 80-150% AMI get 50% of costs covered. This is separate from any utility or state incentives you may also qualify for.
Does air sealing count as insulation for the rebate?
Yes. Air sealing, insulation, and ventilation improvements are grouped together under the same $1,600 HEAR rebate cap. This means a project that includes both blown-in insulation and air sealing would draw from the same $1,600 allowance.
Should I insulate before or after installing a heat pump?
Ideally, insulate first. A well-insulated home allows you to install a smaller, less expensive heat pump that doesn't have to work as hard. Better insulation also improves the energy savings calculations for HOMES rebates. Many energy auditors recommend addressing the building envelope (insulation and air sealing) before upgrading HVAC equipment.
Can I do the insulation work myself and still get the rebate?
HEAR rebates are generally designed to be applied at point of sale through participating contractors. DIY installations may not qualify for the HEAR rebate in most states, though policies vary. However, some utility rebate programs do accept DIY work with proof of purchase. Check your state's specific HEAR program rules and your utility's rebate requirements.
What is the Weatherization Assistance Program and am I eligible?
The Weatherization Assistance Program (WAP) is a federally funded program that provides free energy efficiency improvements, including insulation, to low-income households. You may qualify if your household income is at or below 200% of the federal poverty level. WAP is administered by local community action agencies and services are provided at no cost. Contact your state's WAP provider to apply.
