HVAC System Grants and Rebates: Save Money, Lower Upfront Costs, Get Better Comfort

If you are thinking about replacing an old furnace, air conditioner, or heat pump, 2026 is a year worth paying attention to. Between federal tax credits, state-run rebate programs, and local utility incentives, you can achieve three big goals: save money on your energy bills and equipment, lower your upfront costs with cash‑back incentives that apply directly at the point of sale, and enjoy a more comfortable home with stable heating and cooling all year round. This guide covers the main federal tax credits still active in 2026, the newer state rebate programs funded by the Inflation Reduction Act, income‑based assistance like LIHEAP, and practical steps to make sure you do not leave money on the table.

1. Federal Tax Credits: Section 25C (The One Most Homeowners Can Use)

For most people buying a heat pump, central air conditioner, or furnace in 2026, the Energy Efficient Home Improvement Credit (Section 25C) is where the biggest savings come from. This credit covers 30% of the project cost for qualifying equipment, with specific dollar caps depending on what you install.

How this helps you: A $2,000 tax credit directly reduces what you owe the IRS. It also lowers your long‑term energy bills because high‑efficiency equipment uses less electricity or gas. And modern heat pumps and ACs provide much more even temperatures, eliminating hot and cold spots in your home.

Here is what you need to know. The credit applies only to equipment installed in your primary residence. It is non‑refundable, meaning it reduces what you owe in taxes dollar for dollar, but you will not get a refund if your tax bill is already zero. The credit resets every tax year, so if you spread a large project over two years, you might be able to claim more than once.

Crucially, the equipment must meet strict ENERGY STAR efficiency standards that update annually. For 2026, heat pumps must meet the ENERGY STAR Most Efficient criteria for your climate zone. This is where some homeowners make a costly mistake — they trust a contractor who says "yes, it qualifies" without checking the actual AHRI ratings. Before signing anything, ask for the manufacturer‘s certification statement and verify the model on the ENERGY STAR website.

2. Residential Clean Energy Credit: Section 25D (For Geothermal Systems)

If you are installing a geothermal (ground‑source) heat pump, the credit comes from a different section of the tax code: Section 25D. This covers 30% of the total installed cost with no annual dollar cap through 2032.

Geothermal systems deliver exceptional comfort because the ground temperature remains stable year‑round. They also slash heating and cooling bills by 30‑60% compared to conventional systems. The tax credit makes the higher upfront investment much more manageable.

The two credits are separate. You cannot claim a geothermal system under Section 25C, and you cannot claim an air‑source heat pump under Section 25D. But if you are doing both types of work in the same year (for example, adding solar panels and a geothermal system), you can claim both credits.

3. State Rebate Programs: HOMES and HEAR (Point‑of‑Sale Savings)

Beyond the tax credits, the Inflation Reduction Act allocated $8.8 billion to states for two point‑of‑sale rebate programs: the Home Efficiency Rebates (HOMES) and the Home Electrification and Appliance Rebates (HEAR).

These rebates are designed to lower your upfront cost at the cash register. Instead of waiting until tax season, you get the discount applied immediately when you purchase and install qualifying equipment.

Here is the breakdown of what these programs can cover.

HEAR rebates are income‑based. For low‑ and moderate‑income households, these rebates can cover a substantial portion of the cost and are applied at the point of sale, meaning you see the savings upfront, not when you file your taxes next year. This makes high‑efficiency heat pumps affordable for many more families.

HOMES rebates are designed for whole‑home energy efficiency improvements, including HVAC upgrades combined with insulation, air sealing, and ductwork. These upgrades also make your home more comfortable by reducing drafts and maintaining consistent temperatures room‑to‑room.

Important note: Not every state has launched these programs yet. Some states rolled them out in 2025 and early 2026, but others are still finalizing their plans. The National Association of State Energy Officials (NASEO) tracks the status of each state‘s program. If your state has not started its program yet, keep checking—funding is limited and distributed on a first‑come, first‑served basis.

4. LIHEAP: Emergency Heating and Cooling Assistance for Low‑Income Households

If your household income is low and you need help with heating or cooling costs, the Low Income Home Energy Assistance Program (LIHEAP) is a federal program administered by states. LIHEAP provides assistance with utility bills and, in many states, can also help repair or replace broken heating or cooling equipment.

This program directly lowers your monthly energy bills and can even help you get a new furnace or air conditioner at little or no cost. Eligibility is based on income, household size, and in some cases, disability or age. Check your state‘s LIHEAP office for specific income limits and application windows. Many states also offer weatherization assistance through the same program, which can include insulation and minor HVAC repairs at no cost. These improvements not only cut your bills but also make your home more comfortable by sealing drafts and improving temperature stability.

5. Local Utility Rebates and City‑Level Programs

Beyond federal and state programs, many local electric and gas utilities offer their own rebates for high‑efficiency HVAC equipment. These are often smaller but can be stacked on top of federal tax credits and state rebates, reducing your upfront cost even further.

For instance, the City of Ames, Iowa increased its air‑source heat pump rebate from 1,000in2025to∗∗1,000in2025to∗∗1,200 in 2026** for qualifying high‑efficiency systems. The Pinole Energy Enhancement Rebate (PEER) Program in California offers incentives for heat pump HVAC projects and even provides no‑cost permits for qualifying installations.

Smart tip: Contact your local utility company or check their website. Some utilities offer rebates for smart thermostats, duct sealing, AC tune‑ups, and even heat pump water heaters. These small amounts add up, and because they are rebates, not tax credits, you get the money back immediately. Upgrading to a smart thermostat alone can improve comfort by learning your schedule and keeping temperatures steady while also lowering your bills.

6. How to Claim Federal Tax Credits (Step by Step)

Claiming the federal tax credit is not automatic. You need to take specific steps.

• Keep your receipts and the manufacturer‘s certification statement for the qualifying equipment.
• File IRS Form 5695 with your annual tax return (the form for residential energy credits).
• Complete the appropriate lines for your equipment type (heat pump, AC, furnace, or geothermal).
• Enter the credit amount on Schedule 3 of your Form 1040.

The credit reduces your tax liability directly. If you owe 3,000andclaima3,000andclaima2,000 heat pump credit, you will only owe $1,000. However, if you owe nothing, the credit will not result in a refund check, and you cannot carry leftover credit forward to future tax years.

7. Common Mistakes That Cost Homeowners Thousands

Avoid these pitfalls to make sure you actually receive the money you are entitled to.

• Assuming the contractor knows the tax rules: Many contractors are excellent at installation but not tax experts. Do your own verification on the ENERGY STAR website.
• Ignoring climate zone requirements: A heat pump that qualifies for the credit in the South may not qualify in the North. Check the HSPF2 and SEER2 ratings specific to your region.
• Missing the point‑of‑sale rebate window: State HOMES and HEAR rebates are first‑come, first‑served. If you delay, the funds may run out.
• Not stacking incentives: You can often combine a federal tax credit with a state rebate and a local utility rebate. Do not assume you have to choose one.
• Filing without the manufacturer‘s certification statement: The IRS does not accept "the salesman told me" as proof. You need an actual certification statement from the equipment manufacturer.

8. Where to Start: A Practical Action Plan

If you are ready to upgrade your HVAC system, here is a realistic order of operations to maximize savings, lower upfront costs, and improve comfort.

1. Check your state’s HOMES/HEAR rebate status through the NASEO website or your state energy office. See what income‑based rebates you might qualify for. These can directly cut your upfront price by thousands of dollars.
2. Research your local utility rebates for heat pumps, AC units, smart thermostats, and duct sealing. Every dollar counts toward reducing your out‑of‑pocket expense.
3. Get quotes from at least three contractors and ask for written confirmation that the equipment qualifies for both the federal tax credit and any state rebates.
4. Verify the efficiency ratings on the AHRI directory before signing a contract. Higher efficiency means lower monthly bills and more consistent comfort.
5. File Form 5695 when you do your taxes. Keep all receipts and certification statements in a safe folder.
6. Apply for LIHEAP assistance if you are a low‑income household and need help with heating or cooling costs.
