10 minute read • Last update July 2025
Save on new HVAC systems with tax credits
Let’s start with some facts:
- In Texas, air conditioning and heating can be responsible for 35-40% of your electricity bill.
- New air conditioners can use 50% less energy compared to the systems from the 1970s and between 20-40% less energy than a system that’s 10 years old.
Those are great reasons to invest in a new energy efficient HVAC (heating, ventilation, and air conditioning) system – you can lower your bills! However, installing and upgrading HVAC systems can be expensive. That’s why the government offers HVAC tax credits to promote the adoption of more energy-efficient and environmentally-friendly technologies.
What is an HVAC tax credit?
An HVAC tax credit allows taxpayers to subtract a specified amount directly from their tax liability, reducing the total taxes owed. Under the Inflation Reduction Act (IRA) of 2022, the US Department of Energy sets specific requirements for covered expenses, typically offering a dollar amount or percentage discount for:
- Air conditioner tax credit – $300 for ENERGY STAR rated systems.
- Boiler and new furnace tax credit – $150 for ENERGY STAR rated systems.
- Heat pump tax credit – $300 for ENERGY STAR rated systems.
- Insulation improvement credit – up to $500 (not including installation costs).
Why does the government offer HVAC tax credits?
There are several factors driving the federal HVAC tax credit and rebate scheme.
- Energy conservation and reduced emissions – The primary reason behind federal rebates for HVAC improvements is to promote energy conservation and reduce greenhouse gas emissions.
- Encouraging economic growth and job creation – The more people take advantage of residential credits, the bigger the demand for energy-efficient equipment and related services.
- Decreased reliance on fossil fuels – Newer HVAC systems utilize advanced technologies that reduce the dependence on fossil fuels to help mitigate air pollution and climate change.
- Long-term cost savings for taxpayers – HVAC tax credits incentivize taxpayers to invest in high-efficiency equipment, which reduces operating costs over the lifespan of the system.
Are you eligible for HVAC tax credits?
HVAC tax credits have emerged as a powerful incentive for individuals and businesses to invest in energy-efficient heating, so understanding the eligibility requirements and criteria is essential.
General eligibility requirements
Typically, any home or business owner in the United States who has installed an energy-efficient HVAC system in their primary residence or business can apply. However, several pieces of specific criteria establish eligibility for energy efficient HVAC tax credit.
Specific criteria for different types of HVAC systems
Your ability to claim heat pump, boiler, furnace, or AC tax credits will be based on compliance with the following criteria:
- Purchase and installation dates – In most cases, the equipment must have been purchased and installed within a specific timeframe. However, extensions often apply. For example, under the IRA, tax credit for air conditioners in 2021 was extended to include a tax credit for HVAC replacement in 2022.
- Energy efficiency standards – HVAC systems must meet specific energy efficiency standards measured using industry-recognized metrics – like Seasonal Energy Efficiency Ratio (SEER) in the case of AC tax credit and Annual Fuel Utilization Efficiency (AFUE) for boiler or furnace tax credit.

How to determine if your system qualifies
The exact systems or improvements eligible for HVAC energy credit can vary year by year, so it’s essential to reference the latest IRS regulations or consult a tax professional.
Types of HVAC tax credits and other ways to save
In addition to the federal tax credit, HVAC discounts are also available through various statewide programs – and sometimes even through manufacturers and energy companies directly.
Federal tax credits
Under the IRA, Texans can use federal rebates for HVAC under the following schemes:
- Energy Efficient Home Improvement – Homeowners can deduct 30% of the cost of some home improvements that increase energy efficiency. Specific examples include using federal tax credits for heat pump and boiler/furnace upgrades, insulation improvements, and installing energy-efficient ac units. The tax credit may also be used by households that install smart thermostats.
- Residential Clean Energy – This additional 30% tax deduction is aimed at people interested in switching to solar energy or adding battery storage to their properties to reduce the demands on local power grids.
State and local tax credits
Many states and local governments offer their own HVAC tax credits to encourage energy-efficient practices within their jurisdictions. Currently, Texas does not provide any specific state-wide incentives other than compliance with federal rebates for HVAC.
Manufacturer and electricity company rebates
Electricity bills are typically high across Texas due to reliance on air conditioning. Reliable energy plans from local suppliers like BKV Energy offer cost-effective solutions. In addition, some HVAC manufacturers and energy companies offer rebates to promote their energy-efficient products and services.
Financing plans
If the cost to install a new system is still too high with the federal tax credits and rebates, you can explore financing options. Ask your local heating and cooling contractors if they offer financing for new systems, but make sure to find a plan with a low interest rate.
How to apply for HVAC tax credits
Whether you plan to claim a federal tax credit for insulation or new equipment, the process you’ll need to work through is the same.
Gathering the necessary documentation
To claim back your federal HVAC tax credit, you’ll need to keep hold of your purchase and installation receipts and have a copy of the manufacturer’s certification statement to prove the efficiency ratings of the system. Otherwise, you won’t qualify. Then, you’ll need to download IRS Form 5695.
Filing your tax return
You’ll need to submit IRS Form 5695 with your annual tax return. You ensure you complete it accurately, follow the Form 5695 instructions carefully:
- If you’re applying for energy-efficient air conditioner tax credit or water heater/heat pump energy credit, input a maximum value of $300 in line 22a (Energy Efficient Building Property), and re-enter the same figure on lines 23, 24, and 30.
- If you’re applying for a boiler or furnace tax credit, input a maximum value of $150 in line 22b (Qualified natural gas, propane, or oil furnace or hot water boiler), and re-enter the same figure on lines 23, 24, and 30.
- If you’re applying for a tax credit for a new furnace and air conditioner bundle, input a maximum value of $300 in line 22a, a maximum value of $150 in line 22b, then a maximum value of $450 in lines 23, 24, and 30.
Claiming your credit
To ensure you receive your tax credit, HVAC paperwork must be filed before the annual Tax Day deadline in April (unless you have an approved extension until October). Late filings may result in the loss of federal HVAC tax credit eligibility.
HVAC tax credits and energy efficiency
Financial incentives encourage all participants in the energy supply chain to adopt and invest in more eco-friendly practices:
