How to Claim 2025 HVAC Tax Credits (Without the Headache)

San Antonio summers come with serious heat—and serious energy bills. But for homeowners thinking about upgrading their HVAC system, 2025 offers a valuable, time-sensitive opportunity.

Right now, the federal Energy Efficient Home Improvement Credit is still active, offering up to a 30% tax credit on qualifying HVAC upgrades like high-efficiency central AC systems, ductless units, heat pumps, and smart thermostats. These benefits can add up to thousands of dollars in savings.

But here’s what most homeowners don’t realize: this credit is ending soon. To qualify, your system must be purchased and installed before December 31, 2025. That means time is running out, especially if you want to plan the upgrade properly, get on a contractor’s schedule, and file everything correctly.

If you’re local, today’s a great time to act. On July 23, CPS Energy is hosting a Community Resource Fair with rebate info and energy-saving tips for San Antonio residents. Earlier today, the SPEER Residential HVAC Training webinar covered the importance of ENERGY STAR–rated systems and proper installation—something we handle every day at MD Air Conditioning & Heating.

We help homeowners throughout San Antonio choose qualified equipment, handle the installation, and prepare the paperwork you need to claim your credit. No guesswork. No missed savings.

In this post, we’ll break down how the 2025 HVAC tax credit works, what qualifies, and what steps to take now to avoid missing out.

What Are the 2025 HVAC Tax Credits?

The Energy Efficient Home Improvement Credit, part of the Inflation Reduction Act, gives homeowners a chance to claim up to 30% of the cost of a qualifying HVAC upgrade as a federal tax credit. For 2025, this includes:

Up to $2,000 for installing a qualified heat pump
Up to $600 for a high-efficiency central air conditioner or gas furnace
Up to $150 for a professional home energy audit
Additional credits for insulation and other energy upgrades

This credit is non-refundable, but it directly reduces your tax bill—real money back in your pocket if you qualify.

Unlike past energy credits, this program resets annually, meaning you can potentially claim it each year you complete a qualifying project. But there’s a hard stop: equipment must be installed by December 31, 2025. That means if you’re waiting until next year, you may miss your window.

At MD Air, we help you choose the right system—one that qualifies for both the federal tax credit and any local rebates available through CPS Energy or manufacturer promotions. We also provide the documentation you’ll need at tax time, so you’re not chasing paperwork after the fact.

What Qualifies?

Not every HVAC upgrade qualifies for the 2025 tax credit. To claim your savings, the system you install must meet specific federal efficiency standards, and the work must be done by a licensed contractor.

At MD Air Conditioning & Heating, we make sure every eligible system we install meets or exceeds those standards.

To qualify for the 2025 tax credit, your upgrade must:

Be ENERGY STAR® certified
Be installed by a licensed HVAC contractor
Include detailed documentation of equipment and installation

When you work with MD Air, we provide all the supporting paperwork up front, including your system’s specifications, SEER2 ratings, and installation date—everything your tax professional will need.

Common HVAC upgrades that qualify:

High-efficiency central air conditioners
Must meet ENERGY STAR and SEER2 performance guidelines.
Ductless mini-split systems
Ideal for zoned cooling and homes without traditional ductwork.
Heat pumps
Both air-source and dual-fuel models often qualify for the highest credit amounts—up to $2,000.
Smart thermostats
Select ENERGY STAR models may qualify, especially when installed as part of a broader HVAC upgrade.

Rebate vs. Tax Credit — What’s the Difference?

If you’re planning to upgrade your HVAC system, you’ve probably seen terms like rebate and tax credit used interchangeably. But they aren’t the same, and knowing the difference can help you maximize your savings.

At MD Air Conditioning & Heating, we guide homeowners through both opportunities, so you don’t miss a dollar.

What is a Tax Credit?

A tax credit directly reduces the amount of federal income tax you owe. The 2025 Energy Efficient Home Improvement Credit allows homeowners to claim up to 30% of the total cost of eligible HVAC equipment and installation, with caps depending on the system type.

For example:

A qualified heat pump can earn you a $2,000 credit
A central AC unit may qualify for up to $600
Adding a smart thermostat could offer an additional $150, depending on your setup

To get the credit, you’ll need to file IRS Form 5695 with your 2025 tax return, and you must complete the installation before December 31, 2025. MD Air provides all the necessary documentation to make that process easy for your tax preparer.

What is a Rebate?

A rebate is usually offered at the local or utility level. It may come as instant savings at the time of purchase, or as a check or credit after installation. In San Antonio, CPS Energy offers rebates for installing qualified energy-efficient equipment through approved contractors.

These rebates often vary by season, equipment type, and utility provider, but can range from $100 to over $1,000, depending on what you install and how efficient it is.

MD Air is familiar with the CPS Energy rebate program and others in the area. When we install a qualifying system, we help you apply for any available rebates and ensure the paperwork is submitted correctly and on time.

In short:

Tax credits are federal, reduce your taxes, and require documentation at tax time.
Rebates are usually local or utility-based and may offer faster, upfront savings.

We help our customers in San Antonio take advantage of both. If you’re not sure what your home qualifies for, we’ll guide you through the options based on your goals and budget.

How to File It

Filing for the 2025 HVAC tax credit isn’t as complicated as it sounds—especially when you have the right paperwork and the right partner. At MD Air Conditioning & Heating, we provide everything you need to support your tax claim after installation.

What You’ll Need

To claim the Energy Efficient Home Improvement Credit on your federal tax return, make sure you keep the following:

A copy of your paid invoice, showing equipment and labor costs
Manufacturer certification or product specifications, confirming ENERGY STAR® certification and efficiency ratings
The installation date and contractor information (we include this in your final paperwork)

You’ll also need to file IRS Form 5695 when you submit your 2025 taxes. This form allows you to itemize qualified energy improvements and calculate your total credit. If you work with a tax professional, they’ll use this form to apply the credit toward your return.

MD Air Makes It Simple

When we install a qualified HVAC system, we give you:

An itemized receipt for tax purposes
Equipment documentation confirming energy-efficiency standards
Support if you have questions later on about what to submit

We’ve helped hundreds of homeowners in San Antonio through this process, and we’re always here to answer questions—even after the job is done.

Should You Upgrade Now?

If you’re thinking about waiting until fall or early next year to replace your HVAC system, you may want to reconsider. The 2025 federal tax credit expires on December 31, and installation must be fully completed before that deadline. As schedules fill up later in the year, it can become harder to get your project done in time.

Why Mid-Summer Is Still a Smart Time to Upgrade

Avoid the fall rush: Many homeowners wait until fall to schedule upgrades. Getting ahead now means faster turnaround and more flexibility.
Beat unpredictable lead times: Some high-efficiency systems are in limited supply. The sooner you plan your upgrade, the more choices you’ll have.
Maximize cooling season benefits: Installing now means you won’t just save at tax time—you’ll also enjoy better comfort and lower bills during the hottest weeks of the year.

Plus, with energy costs continuing to rise, a new system could start paying for itself right away through lower monthly bills and available rebates.

At MD Air Conditioning & Heating, we help you:

Select a system that qualifies for both federal tax credits and local rebates
Complete the installation by a licensed, certified team
Prepare the documents you’ll need for tax season

If you’re planning to upgrade, this summer is your window. After December, the credit goes away—and once it’s gone, it’s gone.

Your Last Chance to Upgrade Smart

Upgrading your HVAC system isn’t just about comfort—it’s a financial decision that can impact your monthly bills and your annual tax return. In 2025, homeowners have a unique opportunity to claim up to 30% back through the federal Energy Efficient Home Improvement Credit, but only if the system is installed before December 31, 2025.

We know the process can feel overwhelming. That’s why we make it simple.
