What HVAC Tax Incentives Are Available for Homeowners?
Energy Efficient Home Improvement income tax credits are available for central air conditioning systems, boilers, furnaces, air-source heat pumps, and biomass stoves that reach benchmarks for high efficiency. The credits apply to units purchased and installed between January 1, 2023, and December 31, 2034.
The expanded tax credits represent a significant increase over credits provided for HVAC-related energy efficiency home improvements in 2022 and before. These credits, along with the energy savings you’ll enjoy, are a great way to save money through lower costs for HVAC upgrades and utility bills — not to mention helping transition to a clean energy future.
The eligibility of these systems for tax credits is tied to the unit’s energy efficiency. Here’s a quick list of the terms you’ll need to know to understand how these systems are rated. Most of these terms are new from the Department of Energy as of January 2023 and set the standard for measuring the energy efficiency of HVAC systems.
- SEER2 (Seasonal Energy Efficiency Ratio 2): The most commonly used AC efficiency rating. Calculated by dividing cooling output by input wattage over the three months of summer.
- EER2 (Energy Efficiency Ratio 2): The EER2 rating represents the simplest way to measure AC efficiency. It is calculated by dividing the air conditioning cooling capacity by the maximum electric input in static test conditions.
- HSPF2 (Heating Seasonal Performance Factor 2): Measures your heat pump’s energy efficiency to heat your home throughout the season. It is calculated by dividing the heating output during the heating season by the electricity used to create that output.
- AFUE (Annual Fuel Utilization Efficiency): The ratio of a gas furnace or boiler’s annual heat output compared to its total annual fossil fuel energy consumed.
The table below summarizes the Energy Efficient Home Improvement credits you can take to install different HVAC system elements.
Type of HVAC System
Required Energy Rating
% of costs eligible for credits (2023 - 2032)
% of costs eligible for credits (2033)
% of costs eligible for credits (2034)
Maximum Credit Value
Air-source heat pump
SEER2: 16 or above, EER2: 12 or above, HSPF2: 9 or above
AFUE: 95% or above on gas boilers, variable on oil boilers
Central air systems
SEER2: 16 or above
Biomass fuel stove
Thermal efficiency rating of at least 75%
Natural gas furnaces
AFUE of 97% or greater on gas furnaces, fuel requirements on oil furnaces
Must be approved for use with specific types of fuel, including biofuels
A great way to determine if a qualified HVAC system is eligible for a tax credit is to see if it is Energy Star-certified. If a system meets that certification, it is generally eligible for a tax credit, according to the table above.
- SEER2 rating greater than or equal to 16
- EER2 rating greater than or equal to 12
- HSPF2 rating greater than or equal to 9
If the system meets these criteria, the homeowner can claim 30% of the installation cost, not to exceed $2,000.
Hot water boilers aren’t rated on a scale like electric heat pumps and air conditioner units — their standards are measured a bit differently. The type of fuel also plays a part in the energy efficiency rating of a boiler-based system. To receive tax credits for installation, a boiler must meet the standards below based on its type:
- Gas boilers must be Energy Star-certified and have an AFUE of 95% or greater.
- Eligible oil boilers must be rated by the manufacturer for use with fuel blends of at least 20% of the volume, consisting of biodiesel, renewable diesel or second-generation biofuel.
If a boiler meets these requirements, taxpayers are eligible for tax credits of 30% of the installation cost, not to exceed $600, as long as the unit is purchased and installed between January 1, 2023, and December 31, 2032.
Central air conditioners are popular in the warmer regions of the country because of their ability to efficiently cool an entire home. The cooling system must have been purchased and installed in 2023 or beyond to be eligible for the expanded tax credits.
For split systems, a SEER2 rating of 16 or greater qualifies for a tax credit, and all Energy Star-certified packaged systems are also eligible. Central air conditioners are eligible for 30% of the project cost as a tax credit, not to exceed $600.
While they aren’t among the most popular ways to control the climate inside a home due to initial investment, biomass fuel stoves have gained some traction in colder environments as people look to decrease their carbon footprint.
To qualify for expanded tax credits, a biomass fuel stove must have a thermal efficiency rating of at least 75%. If it qualifies, a stove purchased and installed between 2023 and 2032 is worth 30% of the installation cost in tax credits, not to exceed $2,000.
The criteria your furnace must meet to qualify for a tax credit vary depending on the type of fuel it uses.
- Gas furnaces must be Energy Star-certified and have an AFUE of 97% or greater.
- Oil furnaces must be Energy Star-certified and be approved for use with fuel composed of at least 20% biodiesel, renewable diesel, or second-generation biofuel when measured by volume.
Be sure to consider the additional cost of these fuel requirements when considering your total HVAC system replacement cost. Furnaces that meet these requirements and are installed between 2023 and 2032 are eligible for credits equal to 30% of the project cost of up to $600.
You can claim your residential energy tax incentive when you file your federal income taxes. For federal tax returns filed between 2023 and 2032, you are eligible to claim a credit equal to 30% of the cost of your installation. The dollar limit that this credit maxes out at varies depending on what’s being upgraded. For example, boilers qualify for a 30% installation cost credit of up to $600, while you can claim up to $2,000 for a qualifying heat pump.
To qualify for the maximum credit, you must have your upgrades installed by 2032. Beginning in 2033, the maximum percentage of your installation cost you can deduct is 26%, which drops to 22% in 2034. Beyond 2034, the credit expires; you cannot claim any percentage credit for new installations.
Here’s how to claim your HVAC tax credit when you file your federal income tax return:
- Keep a copy of your installation records and your manufacturer’s certification statement proving the efficiency of your system. You won’t qualify for the rebate program without them.
- Download and complete IRS Form 5695. Fill out the relevant section or sections of the form depending on what you’ve upgraded.
- If you’ve added multiple upgrades during the year, you can claim multiple rebates using the same Form 5695. You don’t need to submit a unique form for each upgrade. However, note that there is an annual limit of $3,200 for efficiency tax credits.
- File these forms when you file your federal taxes. Your tax professional can assist you in ensuring you can claim the maximum refund each year during the tax preparation period.
Because a major goal of the Inflation Reduction Act was a focus on energy efficiency, many home systems beyond HVAC equipment and even a home energy audit are eligible for expanded tax credits under the Act. Below you’ll find information on some popular credits you can take advantage of independently or in addition to HVAC-related credits.
Any type of bulk insulation, including batts, rolls, blow-in fibers, rigid boards, expanding spray, and pour-in-place insulation, qualifies for a tax credit. Products that reduce air leaks can also qualify if they come with a manufacturer’s certification statement. Some examples of items that you can claim under the credit include:
- Caulk designed to air seal
- House wrap
- Spray foam in a can, designed to air seal
You may claim up to 30% of the cost of qualifying insulation installation up to $1,200 between 2023 and 2032.
Installing solar panels or a solar water heater for your home can help your property value and save on energy costs. The Inflation Reduction Act extended and expanded the Residential Clean Energy Tax Credit, which provides solar tax credits.
Unlike the energy upgrades detailed above, solar tax credits aren’t subject to a maximum. As long as your upgrade qualifies, there is no dollar limit on the total amount you can claim. This portion of the Inflation Reduction Act is in effect until 2035.
With a focus on incentivizing the use of roof solar energy quickly, tax credits of up to 30% are in place to entice homeowners to install a solar water heater instead of a traditional heat-pump water heater or solar panels to make their homes self-sufficient. These credits remain at 30% for systems installed before December 31, 2032. This credit drops to 26% of your total cost for 2033 and finally to 22% in 2034.
Any new windows or skylights with the Energy Star certification are eligible for tax credits. Amounts of the credits for windows are 30% of the project cost, not to exceed $600.
The new energy-efficient home tax credits included in the Inflation Reduction Act are a huge boon to homeowners looking to improve their HVAC systems to make their homes more comfortable and efficient. You’ll be able to meet these goals while potentially saving thousands of dollars over multiple years.
If you’re considering replacing an old or worn-down HVAC system or another major home component, you can maximize your tax benefits by spreading upgrades through multiple tax years. Remember that the total annual energy efficiency credit you can claim is $3,200 in one year, with lower limits on individual items. By delaying certain upgrades, you can save more each year on taxes.
For example, if you’re planning a total home overhaul, you could claim up to $1,200 in credit for installation expenses and up to $2,000 for an air-source heat pump. The next year, you could claim up to $2,000 for a heat-pump water heater and up to $500 in credit toward upgrading exterior doors. If you were to make all these upgrades in one year, you could only claim a total of $3,200 in tax credits due to the annual limit.
Solar panel installation isn’t subject to the $3,200 limit — as long as your panels are installed by 2032, you can take the full 30% credit independent of other energy-efficiency home improvements subject to the $3,200 limit.
