Replacing an outdated heating or cooling system can be a major expense. Whether you need a new air conditioner, furnace, heat pump, or geothermal system, the installation cost can make it difficult to upgrade your home. Fortunately, several HVAC rebates and energy-efficiency assistance programs may help reduce these expenses in 2026.
However, the rules have changed. Federal residential energy tax credits that previously covered certain HVAC upgrades ended for qualifying installations or expenditures after December 31, 2025. Homeowners looking to replace their equipment in 2026 should focus on available state incentives, utility rebates, local assistance programs, and other eligible savings opportunities.
Understanding these programs before purchasing equipment can help you avoid unexpected costs and choose a system that meets your household’s needs.
This guide explains how HVAC tax credits and rebates work in 2026, which incentives may still be available, how to check your eligibility, and what you can do to maximize your savings.
What Are HVAC Tax Credits and Rebates?
HVAC incentives help homeowners reduce the cost of installing energy-efficient heating and cooling equipment. These benefits may come from government agencies, utility companies, local programs, or equipment manufacturers.
Although tax credits and rebates both help reduce expenses, they work differently.
HVAC Tax Credits
A tax credit reduces the amount of income tax you owe. For example, a $1,000 tax credit reduces your eligible tax liability by $1,000.
In previous years, homeowners could claim federal tax credits for certain qualifying improvements, including energy-efficient heat pumps, central air conditioners, furnaces, and geothermal systems.
Those federal residential incentives have ended for qualifying HVAC installations or expenditures after December 31, 2025. As a result, homeowners installing a new system in 2026 generally cannot claim the former federal residential energy tax credits for that project.
State tax incentives may follow separate rules, so it is worth checking whether your state offers additional benefits.
HVAC Rebates
An HVAC rebate returns part of the qualifying purchase or installation cost to the homeowner. Depending on the program, the savings may appear as an immediate discount, a reduction on the contractor’s invoice, or a payment after the application is approved.
Rebates may be available through state energy offices, electric and natural gas utilities, local governments, and equipment manufacturers.
Unlike the expired federal residential tax credits, some rebate programs remain available in 2026. However, funding, income limits, eligible equipment, and application requirements vary by location.
Are Federal HVAC Tax Credits Available in 2026?
For most homeowners installing a new residential HVAC system in 2026, the former federal energy tax credits are no longer available.
The Energy Efficient Home Improvement Credit, commonly associated with Section 25C, previously covered certain qualifying home improvements. The Residential Clean Energy Credit under Section 25D also covered eligible clean-energy installations, including geothermal heat pumps.
The law changed in 2025, ending these credits for qualifying property placed in service or expenditures made after December 31, 2025, under their respective rules.
The following table summarizes the situation for common HVAC upgrades.
| HVAC upgrade | Federal residential tax credit for a qualifying 2026 installation |
|---|---|
| Central air conditioner | Former Section 25C credit unavailable |
| Gas, oil, or propane furnace | Former Section 25C credit unavailable |
| Air-source heat pump | Former Section 25C credit unavailable |
| Heat pump water heater | Former Section 25C credit unavailable |
| Geothermal heat pump | Former Section 25D credit unavailable |
| Eligible HVAC installation completed in 2025 | A credit may still be claimed when filing the applicable tax return, subject to the rules |
These changes apply to the former federal residential credits. They do not automatically eliminate state, local, or utility incentives.
Can You Still Claim an HVAC Tax Credit for 2025?
Potentially, yes. If you installed qualifying equipment by the applicable deadline in 2025, you may still be eligible to claim the credit on your 2025 federal income tax return filed in 2026.
Eligibility depends on the equipment, installation date, applicable credit requirements, and supporting documentation. Some qualifying equipment also requires a manufacturer identification number.
Keep your itemized invoice, proof of payment, equipment specifications, and any required manufacturer information. Review the instructions for the relevant tax year before submitting your return.
Do not assume that paying for equipment in 2025 automatically qualifies it for a credit if the applicable rules require installation or placement in service by the deadline.
HVAC Rebates Available in 2026
Even though the former federal residential tax credits have ended, homeowners may still find ways to reduce their HVAC costs.
The most useful programs to investigate are state-administered home energy rebates, utility incentives, manufacturer promotions, and income-based assistance.
1. Home Energy Rebates Administered by States
The federal Home Energy Rebates initiative includes two major programs: Home Efficiency Rebates (HOMES) and Home Electrification and Appliance Rebates (HEAR).
These programs are administered through participating states, territories, and other eligible jurisdictions. Their availability and requirements can differ significantly.
Home Efficiency Rebates (HOMES) support eligible home energy improvements that reduce overall energy consumption. Depending on the active program, projects may include HVAC upgrades, insulation, air sealing, and duct improvements.
Some qualifying projects may receive substantial assistance, with potential rebates reaching several thousand dollars. The actual amount depends on factors such as projected energy savings, household circumstances, project costs, and local program rules.
Home Electrification and Appliance Rebates (HEAR) were designed to help eligible households purchase and install qualifying electric equipment and make related improvements. Potentially eligible work under program rules can include electric heating and cooling equipment, electrical panel upgrades, wiring, and insulation.
However, these programs have undergone changes, and some jurisdictions have revised eligibility requirements in 2026. Certain projects involving a switch from fossil-fuel equipment to electric alternatives may face additional restrictions under applicable updated rules.
Do not assume that either program is accepting applications or that every advertised rebate remains available. Check the current rules, remaining funding, and approval requirements before starting your project.
2. State HVAC Rebates
Some states offer their own energy-efficiency incentives to encourage homeowners to upgrade outdated heating and cooling equipment.
Depending on the location, qualifying improvements may include heat pumps, high-efficiency air conditioners, furnaces, smart thermostats, and ductwork improvements.
Each program establishes its own requirements. Some specify minimum efficiency ratings, while others limit assistance to income-qualified households or projects completed by approved contractors.
To identify relevant programs, start with your state energy office. Look for residential energy-efficiency incentives, HVAC replacement rebates, or heat pump programs.
Confirm that the program is actively accepting applications. An announced incentive may have limited funding or may not yet be available to homeowners.
3. Utility Company Rebates
Your electric or natural gas provider may offer rebates for qualifying HVAC improvements.
These incentives can be useful because they are often designed around local energy-saving goals and may be separate from state-administered programs.
Depending on your provider, eligible upgrades could include high-efficiency heat pumps, central air conditioners, qualifying furnaces, smart thermostats, and duct sealing.
Some utilities require installation by a participating contractor or restrict rebates to specific equipment models. Others may require preapproval before work begins.
Contact your utility provider and request its current residential HVAC rebate requirements. Ask about the eligible models, application deadline, funding limits, and whether the rebate can be combined with other incentives.
4. Manufacturer and Contractor Promotions
HVAC manufacturers and contractors sometimes offer seasonal promotions to encourage customers to purchase selected equipment.
These offers may include manufacturer rebates, discounted installation packages, or reduced prices on qualifying heat pumps and air conditioning systems.
Before accepting an offer, review its terms carefully. Confirm the promotional period, eligible models, documentation requirements, and how the discount will be applied.
Also ask whether the promotion can be combined with a utility or state rebate. Some programs permit multiple incentives, while others impose restrictions.
Compare the final installed price rather than choosing a contractor solely because the advertised rebate appears larger.
5. Weatherization and Income-Based Assistance
Homeowners with limited incomes may qualify for assistance that improves household energy efficiency and reduces heating and cooling costs.
Weatherization programs can help eligible households address problems such as air leakage, poor insulation, and inefficient building components. Depending on the local program and the property’s condition, certain heating or cooling repairs may also be covered.
Eligibility generally depends on household income, location, property conditions, and available funding.
If replacing an HVAC system would create financial difficulties, contact your local weatherization agency to find out whether your household qualifies for assistance.
Which HVAC Systems May Qualify for Rebates?
Not every energy-efficient product qualifies for every incentive. The equipment type, efficiency rating, installation method, and existing heating system can affect eligibility.
Heat Pumps
Heat pumps provide heating and cooling by transferring heat rather than relying entirely on conventional fuel-burning equipment or electric resistance heating.
Because they can provide efficient heating and cooling, they are included in many state and utility incentive programs.
Before purchasing one, check whether the specific model qualifies and whether the program requires a minimum efficiency rating or approved installation method.
Central Air Conditioners
Some state and utility programs provide incentives for qualifying high-efficiency central air conditioners.
Check the required efficiency standard and confirm whether the rebate covers the equipment alone or includes installation expenses. An ENERGY STAR label does not automatically guarantee eligibility for a particular rebate.
Furnaces and Boilers
Certain programs may support qualifying high-efficiency furnaces and boilers. Available incentives depend on the fuel type, equipment specifications, and local requirements.
If you are considering replacing a gas or oil furnace with an electric heat pump, verify any fuel-switching restrictions before committing to the project.
Geothermal Heat Pumps
Geothermal systems use the relatively stable temperature of the ground to help heat and cool a home.
Although the former federal Residential Clean Energy Credit covered eligible geothermal installations, it is no longer available for qualifying expenditures made after December 31, 2025.
Some state or utility incentives may still apply. Because geothermal installations can involve significant equipment and ground-loop costs, compare the full installation price, available incentives, and expected operating expenses before deciding.
How to Find HVAC Rebates in Your Area
Finding the right incentive takes a little research, but a systematic approach can help you avoid missed opportunities.
Step 1: Check Your State Energy Office
Search for current residential HVAC rebates, heat pump incentives, and home energy-efficiency programs. Review the application status and confirm whether funding remains available.
This step helps you distinguish active programs from older announcements that may no longer apply.
Step 2: Contact Your Utility Provider
Ask your electricity or natural gas provider about rebates for the equipment you plan to install.
Provide the proposed system type and model, if available. Specific information helps the provider determine whether your planned upgrade meets its requirements.
Step 3: Review Home Energy Rebate Eligibility
Check whether your state or territory offers HOMES or HEAR rebates and whether the program is accepting applications under its current rules.
Pay particular attention to income limits, equipment restrictions, fuel-switching requirements, and preapproval procedures.
Step 4: Request Itemized HVAC Quotes
Get written estimates from multiple qualified contractors. Each quote should identify the equipment model, installation labor, additional materials, and any rebate included in the proposed price.
Itemized estimates make it easier to compare the real cost of each option rather than relying on a headline discount.
Step 5: Verify Approval Before Installation
Some incentives require an energy assessment, application approval, or reservation of funds before installation begins.
Contact the administrator before signing a binding contract or starting work. Skipping this step can make an otherwise eligible project ineligible for a rebate.
How Much Can You Save on HVAC Upgrades in 2026?
Your potential savings depend on the available incentive, equipment costs, household eligibility, and local program rules.
Consider a hypothetical installation costing $10,000 with an approved rebate of $1,500.
| Cost calculation | Amount |
|---|---|
| Total installation cost | $10,000 |
| Approved rebate | $1,500 |
| Remaining cost | $8,500 |
| Federal residential HVAC tax credit for a new qualifying 2026 installation | $0 |
| Final cost before other savings | $8,500 |
This is an example, not a typical rebate amount or a guarantee of eligibility.
If another incentive is available, your costs may decrease further. However, you must confirm whether the programs allow you to combine benefits and how they calculate eligible expenses.
Remember that rebates reduce upfront costs, while energy savings accumulate over time. Actual savings depend on your climate, energy prices, home insulation, equipment sizing, thermostat settings, and installation quality.
Common Mistakes to Avoid When Applying for HVAC Rebates
A few avoidable mistakes can prevent homeowners from receiving the incentives they expect.
First, do not rely on outdated articles advertising federal heat pump or air conditioner tax credits for new 2026 installations. The former residential credits have ended for qualifying installations or expenditures after the applicable December 31, 2025, deadline.
Second, avoid assuming that every state offers the same rebate or that a program has unlimited funding. Eligibility and availability can change during the year.
Third, do not assume that any ENERGY STAR-certified product automatically qualifies. A program may require a specific model, efficiency rating, or approved contractor.
Finally, get written confirmation of the incentive and its application requirements. A verbal promise from a contractor is not a substitute for the program’s official terms.
