If you’re planning to upgrade your heating or cooling system in 2025, you may have heard about HVAC Qualified Manufacturer (QM) codes. These small four-digit codes can make a big difference when it comes to claiming federal tax credits for energy-efficient home improvements. Understanding how they work can help homeowners take advantage of savings available through the IRS Energy Efficient Home Improvement Credit.
Whether you’re installing a new heat pump, replacing a furnace, or improving overall system efficiency, knowing what QM codes are and how to use them ensures you’re prepared when tax season arrives.
What Are HVAC Qualified Manufacturer (QM) Codes?
HVAC QM codes are four-digit identifiers assigned to specific manufacturers and qualifying equipment used for the IRS Energy Efficient Home Improvement Credit under Section 25C. These codes confirm that the equipment meets the federal efficiency requirements needed to claim a tax credit.
When homeowners install eligible HVAC equipment in their homes, they can use the associated QM code when filing their federal taxes to verify that the equipment qualifies under the program.
For example, if you install an energy-efficient heat pump or furnace that meets federal standards, the manufacturer’s QM code will be used when completing the appropriate IRS forms for the credit.
If you’re considering an upgrade, working with experienced professionals who offer heating installation and replacement services can help ensure the system you install meets both efficiency requirements and your home’s comfort needs.
Why QM Codes Matter for Energy-Efficient HVAC Upgrades
Energy-efficient HVAC systems often come with higher upfront costs, but federal incentives are designed to offset part of that investment. The Energy Efficient Home Improvement Credit allows homeowners to claim tax credits for installing qualifying equipment that reduces energy consumption.
QM codes simplify the process by providing a standardized identifier for eligible manufacturers and equipment. Instead of needing to provide detailed technical specifications on your tax return, the QM code acts as verification that the product meets IRS efficiency requirements.
In other words, the code helps streamline the process for both homeowners and tax professionals when claiming credits.
How QM Codes Work for 2025 Installations
For HVAC equipment installed in 2025, homeowners will use the corresponding four-digit QM code when filing their federal tax return. This code confirms that the installed system qualifies for the credit under the IRS program.
Once the installation is complete, the homeowner includes the appropriate code along with project details when completing IRS Form 5695, which is the form used to claim Residential Energy Credits.
The credit applies to eligible energy-saving installations such as high-efficiency heat pumps, certain furnaces, and other qualifying heating or cooling equipment that meets federal performance standards.
For homeowners replacing outdated systems, upgrading through professional HVAC installation services can improve comfort, efficiency, and potentially qualify for available tax incentives.
How to Claim the Credit on Your Taxes
If you install qualifying HVAC equipment in 2025, claiming the credit typically involves a few simple steps.
First, verify that the equipment you installed qualifies for the Energy Efficient Home Improvement Credit. Your HVAC contractor or manufacturer documentation should confirm eligibility.
Next, locate the QM code associated with the manufacturer of your equipment. This code will be required when completing your tax forms.
When filing your federal taxes, you’ll report the installation details and the associated QM code on IRS Form 5695. This form calculates the residential energy credit that will be applied to your tax return.
Because tax rules can change and individual situations vary, many homeowners choose to consult a tax professional to ensure everything is filed correctly.
Where to Find HVAC QM Codes
Homeowners have several ways to locate the correct QM code for their equipment.
The most reliable source is the IRS Energy Credits Online Portal. You can find updated information and manufacturer codes by visiting the official IRS page here.
This page lists Qualified Manufacturers and their associated codes for products that meet federal efficiency requirements.
Manufacturer websites are another useful resource. Major HVAC manufacturers often publish lists of qualifying equipment along with their corresponding codes. If you purchased equipment from brands like Bosch, Amana, Daikin, or others, the manufacturer’s website can help you confirm the correct identifier.
Your HVAC installer may also provide documentation showing the equipment model and manufacturer information, which can help you locate the correct code.
Finally, your tax preparer or accountant can assist with verifying the correct code and ensuring it’s applied properly on your tax return.
Examples of HVAC QM Codes
Several major HVAC manufacturers have been assigned QM codes for qualifying equipment under the federal program. These codes represent the manufacturer and confirm that their eligible products meet the IRS energy efficiency requirements.
Examples include:
Bosch – K3M2
Daikin / Amana / Goodman – I7Q6
Trane / American Standard – B8T9
Lennox – L7S0
Day & Night / York – I7Q6
Carrier / Bryant / Heil – N8H2
Hisense – S6G0
Fujitsu – F8N3
Coleman – P4O5
These codes are examples tied to manufacturers rather than individual product models. The specific system installed in your home must still meet the efficiency standards outlined by the IRS to qualify for the credit.
What Types of HVAC Systems May Qualify
Many modern HVAC systems are designed to meet high efficiency standards that make them eligible for energy credits.
Common qualifying equipment categories may include high-efficiency heat pumps, certain electric or gas furnaces, advanced HVAC systems designed for improved energy performance, and other qualifying heating or cooling equipment.
However, eligibility depends on the exact product model and its efficiency rating. Not every unit produced by a manufacturer automatically qualifies for the tax credit.
Because of this, it’s important to confirm eligibility before purchasing equipment if your goal is to claim the credit.
Why Energy-Efficient HVAC Upgrades Are Worth Considering
Beyond the potential tax credit, energy-efficient HVAC systems offer several benefits for homeowners.
They typically reduce monthly energy costs by operating more efficiently than older systems. Many modern systems also improve indoor comfort by maintaining more consistent temperatures and better airflow throughout the home.
Advanced systems may also reduce environmental impact by lowering overall energy consumption.
Pairing new equipment with services that improve indoor air quality can further enhance comfort and health inside your home while maximizing the efficiency of your heating and cooling system.
Verify QM Codes Before Purchasing Equipment
One important detail to remember is that the QM code system is a temporary verification measure for qualifying equipment used in 2025 installations.
Before purchasing new HVAC equipment with the intention of claiming the tax credit, homeowners should verify the correct QM code and product eligibility through the IRS website or manufacturer documentation.
Because tax regulations and eligibility requirements can change, confirming the details in advance ensures that your installation will qualify for available incentives.
The Key Takeaway for Homeowners
HVAC Qualified Manufacturer codes are simple but important identifiers that help homeowners claim federal tax credits for energy-efficient heating and cooling upgrades.
These four-digit codes confirm that the installed equipment meets the requirements of the IRS Energy Efficient Home Improvement Credit. When filing taxes, the QM code is reported on IRS Form 5695 along with the project details.
If you’re considering an HVAC upgrade that could improve efficiency and potentially qualify for tax credits, consulting with professionals who provide heating services and system installations can help ensure you select equipment that meets current efficiency standards.
