Free Guide to HVAC Tax Credit Information for 2024

What the 2024 HVAC Tax Credit Covers

The 2024 HVAC tax credit is part of the Inflation Reduction Act, a federal law passed in 2022 that provides tax incentives for home energy improvements. This credit specifically addresses heating, ventilation, and air conditioning systems—the equipment that keeps your home at a comfortable temperature year-round.

The credit covers several types of HVAC equipment and related work. Heat pumps are among the most commonly covered systems. Heat pumps work differently than traditional furnaces because they move heat rather than generate it, making them more energy-efficient. Air-source heat pumps, which pull heat from outside air, can receive up to $2,000 in tax credit per unit. Ground-source heat pumps, also called geothermal systems, can receive up to $3,000 because they're more efficient and require more complex installation.

The credit also covers furnaces, whether they run on natural gas, propane, or oil. A high-efficiency furnace installation or replacement may yield up to $600 in tax credit. Air conditioners, including central air systems and ductless mini-split systems, can qualify for up to $600 per unit. Water heaters that use heat pump technology may qualify for up to $3,500.

Beyond the equipment itself, the credit includes labor costs for installation. The guide explains that you don't get credit only for buying the equipment—the work to install it counts too. This means the total investment in your HVAC system, not just the product price, factors into your tax credit calculation.

Practical takeaway: Review your current HVAC system. If your furnace is over 15 years old, your air conditioner over 10 years old, or your heat pump is aging, researching what modern equipment qualifies may help you understand potential tax credit amounts before getting quotes from contractors.

Income Limits and Who Can Receive the Credit

Unlike some government programs, the 2024 HVAC tax credit has no income restrictions. This means households at any income level can potentially benefit from the credit when they install qualifying equipment. However, the credit amount you receive depends on your tax filing status and how much you paid for the installation.

The credit is structured as a percentage of the cost you pay. For most HVAC equipment, you receive 30% of the installation cost as a credit against your federal income taxes. However, there's a maximum credit per year: $1,200 for most taxpayers. This means if you spend $4,000 on a heat pump installation, you'd receive 30% of that cost ($1,200) as credit, which hits the annual cap.

For low-income households, there's an additional option. Taxpayers with modified adjusted gross income up to 150% of the federal area median income in their location can claim an additional $600 credit for heat pump systems. This means a low-income household installing a heat pump could receive up to $1,800 instead of $1,200.

The guide explains how to determine if you fall into the low-income category. You look at your household income and compare it to income limits published by the IRS for your county. These limits vary significantly by location. For example, a household of four might have a much higher area median income in San Francisco than in rural Mississippi. The IRS publishes these figures annually, and they're available on their website and in tax guides.

You don't need to report anything special when you claim the credit. When you file your taxes for the year you installed the equipment, you report the credit on your tax return using IRS Form 5695. Your HVAC contractor typically provides a form documenting the work performed and cost, which you use to complete your tax forms.

Practical takeaway: Calculate your modified adjusted gross income using the IRS worksheet in the Form 5695 instructions. If you're near the low-income threshold, the extra $600 credit might be significant enough to influence when you schedule your HVAC installation or which system you choose.

Which HVAC Systems and Equipment Qualify

Not every HVAC system purchased in 2024 qualifies for the tax credit. The equipment must meet specific energy efficiency standards set by the Department of Energy. These standards ensure that the credit goes toward systems that genuinely reduce energy consumption and lower carbon emissions.

Heat pumps have the broadest qualification criteria. Air-source heat pumps must have a Heating Seasonal Performance Factor (HSPF) rating of at least 8.5 for cold climates and 7.7 for warm climates. Ground-source heat pumps need a Coefficient of Performance (COP) of at least 8.5. These technical ratings measure how efficiently the system converts energy. A heat pump with a higher rating uses less electricity to produce the same heating or cooling effect as a lower-rated system.

Furnaces must be condensing furnaces with an Annual Fuel Utilization Efficiency (AFUE) rating of at least 95%. A traditional furnace might have an AFUE of 80%, meaning 20% of the fuel burns without producing usable heat. A 95% AFUE furnace captures nearly all the heat from burning fuel, making it substantially more efficient. Natural gas, propane, and oil furnaces can all meet this standard.

Central air conditioners must have a Seasonal Energy Efficiency Ratio (SEER2) rating of at least 16, while ductless mini-split systems need a SEER2 rating of at least 15. Older air conditioning systems might have SEER ratings in the 10-13 range, so this requirement pushes toward genuinely newer technology.

Water heaters that use heat pump technology must have an Energy Factor (EF) rating of at least 2.7 for most models. This is much higher than traditional electric water heaters, which typically have an EF around 0.95. The difference means a heat pump water heater uses approximately one-third the energy of a conventional model.

Your HVAC contractor will know whether proposed equipment meets these standards. When you receive quotes, ask contractors to confirm the SEER2, HSPF, AFUE, or EF rating of the equipment they're recommending. This information typically appears in product specification sheets and the equipment's technical documentation.

Practical takeaway: When comparing HVAC quotes, request the specific efficiency ratings of each system. Compare these against the minimum standards listed above. Systems that exceed the minimum standards by a significant margin tend to save more on energy bills over time, which helps justify higher upfront costs.

How the Tax Credit Works in Practice

The HVAC tax credit functions as a dollar-for-dollar reduction in the federal income taxes you owe. This differs from a tax deduction, which reduces your taxable income. Understanding how the credit actually applies to your tax situation helps you plan financially for your HVAC installation.

Here's a practical example. Suppose you earn $65,000 per year, file as a single taxpayer, and install a qualifying heat pump system in March 2024. The total installation cost, including labor, is $4,500. You would calculate 30% of $4,500, which equals $1,350. However, you can only claim up to $1,200 in a single year, so your credit is capped at $1,200.

When you file your 2024 tax return in early 2025, you report this $1,200 credit on Form 5695. If your total federal income tax liability for the year is $8,000, the credit reduces it to $6,800. You owe $1,200 less in federal taxes because of your HVAC installation.

If your federal tax liability is lower than your credit amount, you have an unused credit. For example, if your tax liability is only $800 and your credit is $1,200, you can carry the remaining $400 forward to the next year. This is called a credit carryforward. You would claim that $400 on your 2025 tax return when you file in 2026. You can carry forward unused credits indefinitely until they're fully used, though the credit program itself expires after December 31, 2034.

The guide walks through filling out Form 5695, which is the IRS form where you claim the credit. You need information from your contractor, including the date the work was completed, the
