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.

Trusted Since 2010

Indow has insulated more than 23,000 buildings - helping reduce carbon emissions by nearly 200,000 tons - and creating comfort across the US & Canada!

    These windows are great! They have improved the quality of our home with reduced thermal loss and reduced noise level! The temperature today is 93° outside, our split system is set at 73° and the inside house temperature is 74°! Before the install of these windows the inside temperature with these conditions would have been 76°! Last night I noticed an ambulance going by. Normally the first thing I recognize is the noise, but last night I didn't realize it was an ambulance until I saw the flashing light! Hannah did a wonderful job coordinating the measurements and the sale! I would recommend these windows to anyone!

    Excellent product, support, and very clear instructions. We look forward to installing these on all our windows.

    I ordered the "acoustic grade inserts" for my bedroom to reduce road noise. They work exactly as advertised. Are they soundproofing? NO. Do they reduce noise to acceptable levels? YES. Compared to other solutions on the market (replacement windows, glass inserts etc) this is much more affordable. However, if you are looking for actual soundproofing, you need to spend more money and get something else. As a bonus, the inserts are tight fitting and have reduced drafts.

    We have single pane historic windows in our house in Newport RI. I was looking for a great solution to both temperature and noise. I decided to try the acoustic indow product.

    I am thrilled with the process and the product. James from Indow was super helpful in answering questions. The laser measuring kit was easy to use and gave you confidence in your own measuring ability as it checks your work. The 4 indow products i ordered came well packaged and were easy to put in.

    Finally, the indow inserts look great and work great. We can no longer hear every conversation outside and the birds don't wake us up every morning. My wife didn't even know they were there. They blend in and can't see them unless you look.

    I highly recommend these. More cost effective than custom storm windows, they look better and you can easily install or remove them as you need.

    Fantastic product and service.

    Indow has established the complete breadth of custom service, from initial enquiry to being very responsive to "after-sales" questions. Ours was and out-of-the ordinary project involving casement windows in a solarium and the end result turned out quite perfectly. Access to information online, instructions arriving with the delivered windows, and answers by phone insured we "enthusiastic amateurs" completed the job to satisfaction.

    I am very pleased with my Indow window inserts. I have a very old house and am near a busy road. I wanted to reduce the noise. I've just installed them and find a considerable reduction in traffic noise. They definitely were worth the cost. The measuring process is quite detailed but easy to follow and my inserts fit perfectly in crooked, 265 year old openings. The company representative Hannah Hendrickson

    was very professional, knowledgeable, and courteous. I highly recommend the Indow

    company.

    I appreciate everything about the whole Indow window process.

    Scheduling and holding a consultation online was easy and seamless. I consultant with KAYA, and he provided a thorough easy-going no pressure to move forward until I was ready consultation.

    Incentives were clearly outlined if I decided to move forward and order to be able to make my inserts even more affordable if I acted in a timely manner with measuring and submitting my order as well as returning the measure kit.

    The Indow inserts arrived within the expected timeframe and installing them was very easy. One of my favorite parts was watching how to install video, because they used humor, and it really held my attention and put me at ease, allowing me to take in all the little details I needed to insert my Indows correctly.

    Within hours, I noticed a temperature shift in the room. It was cooler and more comfortable. The next day when I worked in my office with the Indows the landscaper was across the street with the leaf blower and there was considerable reduction in noise making it a low background buzz instead of a disturbance to the work I was doing. I’ve only had them installed for three weeks and I’ve been so happy with them. It was a great investment for that room in the house that I use for my office.

    A great product. Excellent fit. Greatly reduced outside noise. Easy to install. Very happy!! Match your frame color to your current frame color and they disappear. So glad I got them.

    Well it all starts with customer service. 10 out of 10. Brain McCracken did a great job. The waiting period wasn’t long considering they had to make the window inserts and measuring the window units with the laser was actually fun. Worth every penny!
