About The Energy Efficient Home Improvement Credit

Indow is a certified manufacturer of "eligible building envelope components" (window inserts) that may qualify for the Inflation Reduction Act tax credit pursuant Section 25C of IRS Notice 2022-48.

To qualify for this credit, your window inserts must be installed in a dwelling unit located in the United States and the order must be shipped in the tax year you are claiming the credit for. This is critical: installation must be completed by December 31, 2025 to be eligible for the credit. $1,200 is the maximum allowable credit for all qualified energy efficiency improvements in a single tax year.

Due to the complexity and uniqueness of tax law, we recommend consulting a tax advisor if you are uncertain about your eligibility for this credit.

    Easy to install. They don’t detract from the decor of the room.

    We have a very old home that started as a one room cabin in 1935 in the mountains of CA It has been added on to numerous times and the former owner changes out all of the windows to duel pane except one funky non opening window in a bedroom. Very cold in the winter. We needed a good solution. Found this company, and we are delighted with our purchase. Fits perfectly and is sturdy. Thank you for solving our problem!

    My Indow insert works really well at cutting down the traffic noise from the street outside, which was my goal when purchasing this insert. I have a large window and with the detailed measuring instructions, I got a good fit. It was not difficult to

    install even by myself, as one person. This company was recommended to me by a friend, and I will now highly recommend this company if you are looking for great customer service and a quality produce. Thank you!

    Very high quality materials used in the design and construction of window inserts and easy installation and care videos. Top notch communications of the product progression phases and questions answered in a timely manner.

    I am very impressed with these inserts and the high degree of care that went into their construction and delivery. Very good company and I thank all the workers for the good craftsmanship you provide to such a wonderful product.

    Well done.

    We purchased a total of 7 Indow 'Acoustic' Window inserts for the purpose of reducing the level of noise inside our home from our neighboring home's outdoor A/C - Heatpump units on either side. We couldn't be more pleased with the results. The noise level is reduced (NOT completely) but to the degree that we find ourselves looking out the window on occasion to see whether or not those outside units are actually running. There is a dramatic reduction in the noise level from prior to our installation. Thank you Indows!!

    Window replacement is so expensive. Indow window inserts are a great alternative to extend the life of your windows. Since we had no mechanical issues with the windows inserts were a good choice.

    The staff was great to work with. They gladly answered any questions I had. The inserts were very well packaged for shipping. It was a fine experience from start to finish.

    We received our windows and installed them right away. We live very close to a busy highway behind our home, so noise has always been an issue. We ordered the acoustic inserts for three windows, and I can honestly say I noticed a difference immediately. The sound isn’t completely gone (which is understandable with a highway nearby), but it has been reduced enough that I no longer need to sleep with earplugs, which is a huge win for us.

    The customer service was also great — they were helpful and kept us updated throughout the entire process. Installation was fairly easy, and the installation videos were very clear and helpful. Overall, we’ve been very happy with our experience and have already recommended this product to a friend.

    We ordered the Thermo insulation inserts for our cabin off the Blue Ridge Parkway in VA. The windows are old and drafty and with the wind and the cold that has happened this year, the inserts have really came through. We used to see the curtains move when the wind was blowing hard and the cold would come right through the windows. After installing the inserts, which was so easy, there is a night and day difference with the window inserts and the house is actually warmer and the heat is not running constantly. These inserts have saved us thousands of dollars in window replacments and you can not even tell that the inserts are in the windows. Thank you Window Inserts for all your help.

    Excellent product for windows outside noise problems. Bought 2 Indow inserts for our bedroom windows. I was hesitant at first, but after installing our new acoustic Indows I was impressed. It really cut down on outside noise tremendously. Got few estimates for 2 new windows to replace the old ones. The cost of installing new windows was a shocker. Now, I am happy with my choice to go with Indows. Highly recommend!

    Thank you indows! We are very happy with our 5 new indows which were delivered by Fedex and in

    perfect shape when opened. Our dining room and adjoining room are warmer in the cold, which is a bit more this winter

    The indows were installed easily by myself and my wife as expected and look great. In total we have installed 8 of your products. Thank you again, Randy and Mary Jane.

    The inserts came as scheduled. They were crated very well. They fit perfectly. Great product and service.

    Quick delivery and the windows fit very well even with how many anomolies there were in our 107 year old house. Installation took longer than I expected with 12 units to install, but once I figured out what I was doing it went much quicker. We ordered white frames with the plan to eventually repaint all the interior trim. In the mean time, the frames hide very well with our curtains and sheers. We are glad to get the decreased noise and improved thermal performance without ruining the exterior of this historic home.
