Free Guide To HVAC Tax Credits In 2024

Understanding HVAC Tax Credits for 2024

The federal government offers tax credits designed to help homeowners pay for improvements that make their homes more energy-efficient. HVAC systems — which include heating, ventilation, and air conditioning — fall into this category. A tax credit is different from a tax deduction. With a tax credit, you subtract the credit amount directly from the taxes you owe to the federal government. This makes credits more valuable than deductions for most people.

In 2024, the primary federal tax credit for HVAC improvements is part of the Inflation Reduction Act, passed in 2022. This law created a residential energy credit that covers certain HVAC equipment and installation costs. The credit can be worth up to $3,200 per year for qualified improvements, though the amount depends on the specific equipment and your household income level.

It's important to understand that tax credits are not the same as rebates or subsidies. Rebates come from manufacturers or utilities and reduce what you pay upfront. Tax credits reduce what you owe in taxes when you file your return. Some homeowners may be able to use both rebates and tax credits, which can significantly lower the total cost of HVAC upgrades.

The 2024 tax credit rules also introduced the concept of "prevailing wage" requirements in certain situations. If you live in a state with prevailing wage rules, the credit amounts may be higher if your HVAC contractor pays workers at prevailing wage rates. Understanding these details helps you make informed decisions about your HVAC investment.

Practical takeaway: Before planning an HVAC upgrade, learn the difference between tax credits, rebates, and deductions. Tax credits directly reduce your federal tax bill, making them one of the most valuable incentives available for home energy improvements.

Which HVAC Systems Qualify for Credits

Not every HVAC system or upgrade qualifies for the federal tax credit in 2024. The equipment must meet specific energy efficiency standards set by the Department of Energy. The most common systems that may receive credit include air source heat pumps, ground source heat pumps, and certain air conditioning systems that meet SEER2 ratings of 16 or higher.

Air source heat pumps have become one of the most popular options for the credit. These systems both heat and cool your home by moving heat in and out of your house. They work well in most climates and are often more efficient than traditional furnaces and air conditioning units. A modern air source heat pump can heat your home in winter and cool it in summer, potentially replacing two separate systems.

Ground source heat pumps, also called geothermal systems, work by drawing heat from the ground. While these systems are more expensive to install than air source heat pumps, they are very efficient and often qualify for larger credit amounts. Ground source systems work well for homeowners who have space for the underground loops that these systems require.

The credit also covers certain air conditioning systems, but only if they meet strict efficiency ratings. Standard window units or older central air systems typically do not meet the requirements. Additionally, the equipment must be new — used or refurbished systems do not receive credit.

Beyond the equipment itself, the installation must meet certain standards. The system must be installed in your primary residence, which means a home where you live most of the year. Second homes, rental properties, and investment properties do not qualify for this credit. The installation must also be done by a licensed contractor in most cases.

Practical takeaway: Check the specific efficiency ratings (SEER2 for air conditioning, HSPF2 for heat pumps) before purchasing an HVAC system. The Department of Energy maintains a list of qualifying equipment models, which you can review before making your purchase decision.

Credit Amount and Income Limits in 2024

The amount of tax credit you can receive depends on the type of equipment you install and your household income. For most homeowners, the credit covers 30% of the cost of the HVAC equipment and installation, up to certain limits. However, the Inflation Reduction Act introduced income limits that can reduce or eliminate the credit for higher-income households.

For a single filer, the credit begins to reduce at a modified adjusted gross income of $200,000. For married couples filing jointly, the limit is $400,000. If your income exceeds these thresholds, the credit amount decreases. This means that very high-income households may not receive any credit at all. The exact reduction depends on how much your income exceeds the threshold.

For air source heat pumps, the credit can be up to $2,000 for equipment and installation combined. For ground source heat pumps, the credit can reach $3,200. Heat pump water heaters receive a separate credit of up to $2,000. If you install multiple qualifying systems in the same year, you may be able to claim credits for each one, but the total cannot exceed $3,200 in any single year.

These credit amounts have changed from previous years. Prior to 2024, the credit structure was different and covered a smaller percentage of costs. The Inflation Reduction Act expanded the credits and made them available to more homeowners. However, it also introduced the income limits mentioned above.

The credit is not refundable in all cases. This means that if the credit is larger than the taxes you owe for the year, you cannot receive the extra amount as a refund. However, you may be able to carry unused credit amounts to future years in some situations. Your tax professional can explain how this works for your specific situation.

Practical takeaway: Calculate your modified adjusted gross income to see what credit amount may be available to you. If your income is near the phase-out limit, discuss with a tax professional how income changes might affect your credit eligibility in different years.

Prevailing Wage Requirements and Credit Variations

One of the more complex aspects of the 2024 HVAC tax credit involves prevailing wage requirements. In certain situations, installing an HVAC system with workers paid at prevailing wage rates can increase the credit amount from 30% to 40% of the total cost. This adds significant value to the credit, making it worth understanding how these requirements work.

Prevailing wage refers to the wage rates that construction workers must be paid on certain government-funded projects. These rates are typically higher than standard market wages and vary by location and job type. When the IRS rules include prevailing wage bonuses, it means that HVAC contractors can pay workers at these higher rates, and homeowners can receive a larger credit as a result.

Not all states or locations have prevailing wage requirements for residential HVAC work. Some states have established their own prevailing wage rules, while others follow federal guidelines. You would need to research the rules in your specific state or county. The IRS has published guidance on which areas have prevailing wage requirements for residential energy credit purposes.

If your area has prevailing wage rules for residential HVAC work, the contractor installing your system can choose whether to pay prevailing wages or not. If they do pay prevailing wages, the credit increases to 40% of the cost, up to the annual limit of $3,200. If they do not, the credit remains at 30%. This choice is up to the contractor, though the higher credit amount may motivate them to pay the higher wages.

Contractors who pay prevailing wages must keep documentation showing that workers were paid at the required rates. This documentation may be requested by the IRS if you claim the credit on your tax return. The credit amount increase applies to both the equipment cost and the labor cost associated with the installation.

Practical takeaway: When requesting quotes for HVAC installation, ask contractors whether prevailing wage requirements apply in your area and what the difference in cost would be with prevailing wages included. Compare this against the increased credit amount to determine the net cost difference.

How to Document and Claim the Credit on Your Taxes

To claim the HVAC tax credit on your 2024 tax return, you will need to gather specific documentation and complete the appropriate IRS forms. Proper documentation is essential because the IRS may request proof that your equipment meets the energy efficiency requirements and that the installation was done in your primary residence.

Start by keeping all receipts and invoices related to your HVAC installation. These documents should include the date of purchase, the price paid, the model number of the equipment, and a description of the work performed. The contractor should
