Understanding the Energy Efficient Home Improvement Tax Credit

Did you know that you can claim a tax credit for energy-efficient windows? How about receiving a tax break for energy-efficient appliances? The cost of upgrading items in your home, like your HVAC, windows, doors, and insulation, can quickly become expensive. When choosing between different products, the IRS wants to incentivize you to choose energy-efficient property, which is why they offer tax breaks for energy-efficient home improvements.

In this article, we’ll break down the Energy Efficient Home Improvement Credit, including what qualifies, the credit limits, and how to claim this tax incentive. If you have any questions about your specific energy-efficient upgrades, consult with your tax accountant.

What is the Energy Efficient Home Improvement Tax Credit?

The Energy Efficient Home Improvement Tax Credit is a credit homeowners can claim up to $3,200 each year. This credit is in effect through 2032. Prior to 2023, the Energy Efficient Home Improvement Credit was limited to a lifetime amount of $500. This meant that once taxpayers reached the $500 credit, they could no longer claim any additional credit. However, under the Inflation Reduction Act of 2022, the credit was reworked, allowing taxpayers to claim a credit each year that qualifying expenditures are made.

The maximum nonrefundable credit you can claim each year is $1,200 for energy-efficient property and $2,000 per year for qualified heat pumps, biomass stoves, biomass boilers, and water heaters. It’s important to note that there are other limitations for energy-efficient property. Exterior doors are limited to $250 per door up to $500, exterior windows and skylights are limited to $600, and home energy audits are limited to $150. We’ll talk more about these limits in the next section.

Who Qualifies for the Energy Efficient Home Improvement Credit?

To qualify for a tax write-off for energy-efficient windows or an energy-efficient AC tax credit, there are a few conditions that must be met. First, the home must be your main home. This means you primarily reside there. Second, the home must be located in the United States. If you are a United States resident living overseas, improvements on an overseas home would not qualify.

Another important qualification criteria for the Energy Efficient Home Improvement Tax Credit is that the home is not new. Eligible improvements are to an existing home, not a new build. You may be eligible for other energy-efficient credits on newly built homes. Moreover, landlords who do not live in the home cannot take the credit.

What Improvements Qualify for the Energy Efficient Home Improvement Tax Credit?

The federal tax credit for energy-efficient home improvements applies to certain upgrades. Before we get into the specifics of each section of property type, it’s important to understand that the property placed in service must be new. Installing a used air conditioner wouldn’t qualify since you were not the first user of the property. All materials and systems must be new to qualify.

HVAC Energy Efficient Tax Credits

Energy-efficient AC tax credits are available up to $600. In addition, natural gas, propane, and oil water heaters, furnaces, and hot water boilers are also eligible for a credit of up to $600. To qualify for HVAC energy-efficient tax credits, the property must meet or exceed the Consortium for Energy Efficiency’s highest tier. Electrical components to install the HVAC systems are also eligible expenditures, including panelboards, subpanelboards, branch circuits, and feeders if they meet the National Electric Code and have 200 amps or more.

Tax Credit for Energy-Efficient Windows and Doors

Eligible doors and windows must meet Energy Star certification requirements. Additionally, each door is limited to a credit of $250. Let’s say that you replaced three qualifying exterior doors at $1,000 each. Your total door credit will be capped at $500. The tax write-off for energy-efficient windows also has a $600 limitation. Labor costs related to windows and doors do not qualify.

Insulation and Sealing Materials

Insulation and air sealing materials and systems must meet International Energy Conservation Code standards. The credit for insulation is limited to $1,200. Insulation and air sealing materials are one of the few property types that will not require a qualified manufacturer PIN in 2025 (more on this in a later section). Labor costs associated with insulation and air sealing materials do not qualify for the credit.

Home Energy Audits

Home energy audits are limited to a credit of $150. To qualify, the home energy audit must be a written report by a qualified home energy auditor through one of the Department of Energy’s certification programs.

What are the Energy Efficient Home Improvement Tax Credit Limits?

Tax breaks for energy-efficient homes do have some limitations in addition to credit limits. Let’s explore these limitations in more detail.

Business Use of Home

If you use your home to run a business, your credit may be limited. If the area of your home allocated to business use is less than 20%, you qualify for the full credit. However, if business use is over 20%, the portion of expenses allocable to the credit is reduced. Let’s say that your business uses 50% of your home. Your credit is limited to 50% of the expenses.

Nonrefundable

Tax breaks for energy-efficient homes are nonrefundable. This means that the credit cannot exceed your tax due. Let’s say that your tax due before your credit computation is $2,000. Your Energy Efficient Home Improvement Credit claim totals $2,500. The excess $500 will be carried forward to future years.

It’s important to distinguish between your tax due and your refund. The credit limitation is imposed on your tax due, which is before any withholding. Using the above example, let’s say that you had $3,000 withheld during the year from your W-2. Your refund, assuming no other factors, would be $3,000. The credit can reduce your calculated tax down to zero, helping you generate a larger refund.

Qualified Manufacturer

Beginning in 2025, there is an additional layer of complexity when claiming the tax credit for energy-efficient home improvements. To be eligible, the property must be produced by a qualified manufacturer. A qualified manufacturer is one that has a valid registration and agreement with the IRS through the IRS Energy Credits Online portal. Each qualified manufacturer will receive a PIN that will be shared with taxpayers. This PIN is required to submit a credit claim.

The qualified manufacturer requirements apply to exterior doors, windows, skylights, central air conditioners, biomass stoves, biomass boilers, water heaters, heat pumps, hot water boilers, and furnaces. Without the PIN on Form 5695, you will not be able to claim the Energy Efficient Home Improvement Credit.

How to Claim the Energy Efficient
Home Improvement Tax Credit?

The federal tax credit for energy-efficient home improvements is claimed by filing Form 5695 in the year the property was placed in service. For example, energy-efficient home improvements made in 2025 would be reported on your 2025 income tax return. This credit cannot be claimed for improvements outside of the tax year. For example, if you forgot to claim the credit in 2024, you would need to amend your 2024 tax return.

Summary

Claiming tax breaks for energy-efficient homes can help lower the financial impact of upgrading your furnace, AC, windows, doors, and more. If you’re ready to get started with upgrading your HVAC, contact one of our team members today to schedule your free consultation

Summer in North Carolina means longer days, higher temperatures, and plenty of afternoon thunderstorms. While these storms often provide a brief break from the heat, they can also pose a serious threat to your home's HVAC system. Many homeowners think of severe weather as a roofing or landscaping concern, but power surges, lightning strikes, and heavy rainfall can all impact your air conditioning system. As we head into the hottest months of the year, now is the perfect time to make sure your HVAC equipment is protected. How Summer Storms Affect Your HVAC System Your outdoor air conditioning unit is designed to withstand normal weather conditions, but severe summer storms can create problems that lead to costly repairs. Some of the most common storm-related HVAC issues include: Electrical damage from lightning strikes Power surges that damage control boards and capacitors Debris blown into outdoor units Flooding around equipment Tripped breakers and electrical interruptions Even if your system appears to be running normally after a storm, hidden electrical damage can sometimes surface days or weeks later. The Risk of Power Surges One of the biggest threats to HVAC systems during summer storm season is a power surge. When lightning strikes nearby or utility power fluctuates during a storm, a sudden spike in electricity can damage sensitive HVAC components. Modern air conditioning systems rely on electronic control boards, variable-speed motors, and advanced thermostats that can be vulnerable to voltage spikes. A single surge can result in expensive repairs or even premature system replacement. Keep Your Outdoor Unit Clear Summer storms often bring strong winds that can scatter branches, leaves, and other debris throughout your yard. After a storm passes, take a few minutes to inspect your outdoor unit. Remove any debris that may have accumulated around it and make sure there is at least two feet of clear space surrounding the equipment. Restricted airflow can reduce efficiency and put unnecessary strain on your system during the hottest days of summer. Watch for Drainage Issues Heavy rainfall is common throughout Wake Forest during the summer months. If water pools around your outdoor unit, it can create problems over time. While HVAC equipment is built to handle rain, standing water can contribute to corrosion, soil erosion around the unit, and potential electrical concerns. If you notice frequent pooling around your system, improving drainage around the equipment may help protect it from future damage. Signs Your HVAC System May Have Been Affected by a Storm After a significant thunderstorm, keep an eye out for warning signs such as: The system won't turn on Frequent breaker trips Unusual noises Weak airflow Inconsistent cooling Thermostat communication issues Higher-than-normal energy bills Addressing these issues early can often prevent larger and more expensive repairs later. Consider Surge Protection for Your HVAC System Many homeowners protect televisions, computers, and appliances with surge protectors but overlook one of the most expensive pieces of equipment in their home—the HVAC system. A professionally installed HVAC surge protector can help shield critical components from damaging electrical spikes and may save you from costly repairs down the road. If your system is newer or contains advanced electronics, surge protection is worth considering. Schedule a Mid-Summer HVAC Inspection Your air conditioner works hardest during June, July, and August. A mid-season inspection can help identify storm-related damage, electrical concerns, or performance issues before they lead to a breakdown during a heat wave. Routine maintenance also helps improve efficiency, lower energy costs, and extend the life of your equipment. Stay Comfortable All Summer Long North Carolina's summer weather can be unpredictable, but your home comfort shouldn't be. Taking a few simple steps to protect your HVAC system from storms, power surges, and heavy rainfall can help keep your equipment running reliably throughout the season. If you've experienced a recent storm or simply want peace of mind before the hottest weather arrives, Casey Services is here to help. Our experienced technicians can inspect your system, identify potential issues, and keep your HVAC equipment operating at its best all summer long.

As temperatures rise across Wake Forest and the surrounding areas, many homeowners start noticing something frustrating inside their homes — it feels sticky and humid even though the air conditioner is running. If your home never quite feels comfortable during a North Carolina summer, your HVAC system may be cooling the air without properly removing humidity. And while temperature matters, indoor humidity plays a huge role in how comfortable your home actually feels. Why Humidity Matters More Than You Think Your air conditioner does more than cool your home. It also helps remove moisture from the air. When humidity levels climb too high indoors, you may notice: Rooms feeling clammy or muggy Uneven comfort throughout the house Musty odors Increased allergy symptoms Condensation around vents or windows Higher energy bills Even if your thermostat says 72 degrees, high humidity can make your home feel much warmer and far less comfortable. What Causes Indoor Humidity Problems? There are several reasons your HVAC system may struggle to control humidity during the summer months. Your AC System May Be Oversized Many homeowners assume bigger is better when it comes to air conditioning, but an oversized system can actually create humidity issues. If your AC cools the home too quickly, it shuts off before completing a full cooling cycle. That means it does not run long enough to properly remove moisture from the air. The result? A cool house that still feels damp and uncomfortable. Dirty Coils or Poor Maintenance When your system is dirty or not properly maintained, airflow and performance suffer. Reduced airflow can limit your system’s ability to dehumidify your home effectively. Regular HVAC maintenance helps keep your system operating efficiently during the hottest and most humid months of the year. Air Leaks Around Your Home Warm outdoor air can sneak into your home through gaps around doors, windows, attic spaces, or ductwork. As that humid air enters your home, your HVAC system has to work harder to maintain comfort. In many cases, humidity issues are a combination of HVAC performance and air leakage. Your System Is Aging Older HVAC systems often struggle to maintain consistent indoor comfort, especially during North Carolina summers when heat and humidity levels stay high for extended periods. If your system constantly runs but your home still feels uncomfortable, it may be time to evaluate whether your equipment is still meeting your home’s needs efficiently. What Is the Ideal Indoor Humidity Level? Most homeowners feel the most comfortable when indoor humidity stays between 40% and 50%. Higher humidity levels can make your home feel warmer than it actually is, forcing you to lower the thermostat and increasing energy costs. Proper humidity control can help your home feel cooler without constantly adjusting the temperature. How Casey Services Can Help At Casey Services, we help homeowners throughout Wake Forest and the surrounding areas improve comfort, efficiency, and indoor air quality all summer long. Whether your system needs maintenance, airflow adjustments, repairs, or a full evaluation, our team can help identify what is causing your home to feel humid and uncomfortable. If your air conditioner is running but your home still feels sticky, it may be time to have your system inspected before the hottest part of summer arrives. Contact Casey Services today to schedule your HVAC service and keep your home cool, comfortable, and humidity-free this summer.

Spring in Wake Forest brings warmer temperatures, blooming trees, and one thing every North Carolina homeowner knows well — pollen season. That yellow-green layer covering cars, porches, and sidewalks is more than just an annoyance. Spring pollen can also affect your HVAC system, indoor air quality, and overall home comfort in ways many homeowners don’t realize. If your allergies seem worse indoors or your HVAC system is working harder this time of year, pollen buildup could be playing a major role. How Spring Pollen Gets Into Your Home Even with doors and windows closed, pollen still finds ways inside your home. Every time doors open, pets come in from outside, or air circulates through your HVAC system, pollen particles can enter and spread throughout the house. Once inside, your HVAC system becomes the first line of defense. Your air filter is designed to capture airborne particles like pollen, dust, and debris before they continue circulating through your home. But during peak spring pollen season in North Carolina, filters can become clogged much faster than usual. What Happens When Your Air Filter Gets Clogged A dirty or overloaded air filter restricts airflow throughout your HVAC system. When airflow is reduced, your system has to work harder to maintain comfortable temperatures. That extra strain can lead to: Reduced cooling efficiency Higher energy bills Uneven temperatures throughout the home Poor indoor air quality Increased wear and tear on HVAC components More dust and allergens circulating indoors Many homeowners assume allergy symptoms are only caused by outdoor exposure, but poor HVAC airflow and dirty filters can make indoor conditions even worse. Why Indoor Air Quality Matters During Pollen Season Spring allergies are especially common across Wake Forest and the surrounding areas because of the heavy tree pollen that arrives each year. If your HVAC system is not properly maintained, pollen particles can continue circulating through your home long after you come inside. Signs your indoor air quality may be suffering include: Increased sneezing or allergy symptoms indoors Dust buildup around vents Stale or stuffy air More frequent headaches or congestion Excess dust throughout the home Routine HVAC maintenance and proper filtration can make a noticeable difference in indoor comfort during allergy season. How Often Should You Change Your Air Filter in Spring? During peak pollen season, many homeowners need to replace their air filters more frequently than they do during winter. While every home is different, spring is a good time to check your filter monthly — especially if you: Have pets Live near heavy tree coverage Keep windows open often Have family members with allergies or asthma Notice excess dust indoors A clean air filter helps your HVAC system operate more efficiently while improving indoor airflow and reducing airborne allergens. Don’t Ignore Reduced Airflow If certain rooms feel stuffy, airflow seems weaker than usual, or your system runs longer throughout the day, pollen buildup may be contributing to the problem. In some cases, clogged filters can even lead to frozen evaporator coils or unnecessary strain on the blower motor. Addressing airflow issues early can help prevent larger HVAC problems as temperatures continue rising heading into summer. Simple Ways to Protect Your HVAC System This Spring There are several easy ways homeowners can help reduce pollen-related HVAC issues: Replace air filters regularly Schedule seasonal HVAC maintenance Keep windows closed during high pollen days Vacuum and dust frequently indoors Clean around vents and return air grilles Consider upgraded filtration or indoor air quality solutions Preventive maintenance is especially important this time of year because your system is preparing for the heavier cooling demands of summer. Prepare Your HVAC System Before Summer Arrives North Carolina pollen season does more than trigger allergies — it can also impact your HVAC system’s efficiency, airflow, and performance. At Casey Services, we help Wake Forest homeowners stay comfortable year-round with professional HVAC maintenance, repairs, and indoor air quality solutions. If your home feels dusty, stuffy, or your system seems to be working overtime this spring, now is the perfect time to schedule an HVAC inspection before summer heat arrives.

The U.S. has banned the production and import of Freon (R-22), so while you can still use your current Freon-based AC, repairs are costly and often impractical due to limited supply and certified technicians. Since new units no longer support R-22, the most cost-effective long-term solution is to replace your system with a modern, eco-friendly alternative.
