At Reliable Design-Build-Remodel here in Birmingham, AL, we know that choosing the right windows isn’t just about curb appeal—it’s about comfort, long-term savings, and doing right by the environment. One of the most impactful upgrades you can make to your home is investing in energy efficient window replacements. Not only do they help reduce your utility bills, but they also enhance your home’s overall performance and value. In this post, we’ll walk you through everything you need to know about these smart window upgrades, including what to choose, what it might cost, and how you can benefit from federal tax incentives.

What are the most energy efficient replacement windows?
When it comes to energy efficiency, not all windows are created equal. The most energy efficient replacement windows are typically those certified by ENERGY STAR® and feature double or triple-pane glass with low-emissivity (Low-E) coatings, argon or krypton gas fills, and insulated frames. Popular styles like casement and awning windows are particularly efficient due to their compression seals, which prevent air leaks better than sliding windows. Frames made from vinyl, fiberglass, or composite materials also outperform traditional aluminum when it comes to insulation. At Reliable Design-Build-Remodel, we recommend choosing products that carry NFRC (National Fenestration Rating Council) labels so you can easily compare performance ratings like U-Factor and Solar Heat Gain Coefficient.
How much does it cost to replace windows with energy efficient windows?
The cost of energy efficient window replacements can vary significantly based on the size of the window, the frame material, glazing options, and the complexity of the installation. On average, homeowners can expect to pay between $500 and $1,200 per window, including labor. Premium options with triple glazing or advanced Low-E coatings can run higher, but they also offer greater long-term savings on energy bills. At Reliable Design-Build-Remodel, we offer transparent pricing and quality installations that ensure you get the maximum return on your investment. We’re always happy to walk you through product choices and pricing tailored to your home and budget.

How does the 30% tax credit for energy efficient windows work?
Thanks to the Inflation Reduction Act, homeowners can now take advantage of a 30% federal tax credit for qualified energy efficient home improvements, including window replacements. This applies to purchases made through 2032. For more information, visit the IRS website page on the topic! https://www.irs.gov/credits-deductions/energy-efficient-home-improvement-credit
What type of window covering is most energy efficient?
While new windows do the heavy lifting, window coverings also play a key role in energy efficiency. The most effective coverings include cellular shades (also known as honeycomb shades), which trap air in pockets and create an insulating barrier. Thermal curtains and insulated Roman shades can also significantly reduce heat transfer. In sunny climates like ours here in Alabama, exterior shading devices such as awnings or solar screens offer excellent protection against solar gain. Pairing energy efficient window replacements with the right coverings can maximize comfort and efficiency all year long—and we’d be happy to help you explore smart combinations for your home.
Can I deduct window replacement on my taxes?
You can’t deduct the full cost of window replacements from your taxes as you might with certain business or medical expenses. However, you can claim a tax credit for a portion of the cost, as mentioned earlier. Specifically, under the Energy Efficient Home Improvement Credit, homeowners can receive a credit equal to 30% of the cost of qualified windows, up to a maximum of $600 annually. It’s important to note that the credit applies to the cost of the windows only—not the installation labor.
How do I know if my new windows qualify for tax credit?
To determine if your windows qualify for the tax credit, look for products that are ENERGY STAR® Most Efficient and meet the specifications for your climate zone—in our case, the Southern Climate Zone. Each qualified window should come with an NFRC label that outlines its performance ratings. The key numbers to check are the U-Factor (should be ≤ 0.22 to 0.30) and Solar Heat Gain Coefficient (SHGC ≤ 0.23 to 0.40), depending on your needs. Also, make sure to keep all receipts and manufacturer certifications, which you’ll need when filing your taxes. At Reliable, we only recommend products that meet or exceed these standards, and we ensure our clients receive the proper documentation for tax purposes.
