The inserts are great, installation went good . Your putting the numbers on the inserts made it very easy. These things work as well as you said they would. I had used film on the inside of the windows to help during Winter. These are so much better than installing film. I am happy with my investment and wish you well with your product.

By all means, you may use my email. I would rate your product at 5 stars.

Inserts look and perform great!

Thank you so much for your wonderful product and lightning fast shipping. I'll be sure to recommend you guys to anyone that needs a window cover.

Thank you again.

I ordered window inserts last October and first of all I LOVE THEM. My sister has decided that she wants to get them... You are more than welcome to use my testimony. The inserts are that great!

(Her sister did order a house full of inserts later in 2012.)


Just wanted to let you know that I have now seen the product and I am very impressed. I was concerned since the product was going to Canada but had no issues with International orders at all. Every part of the order went perfect from the ordering to the shipping to the packaging to the fit and quality of the inserts. First of all, the order was very easy to do, easy to measure and payment types offered were great. Second, as far as shipping, packaging was done extremely well so nothing would break, you took care of the shipping and all went great. Third, my wife installed the inserts with ease before I got home from work and everything fit perfect. The inserts are great quality. They look so good that you cant even tell they are there. Thanks again for the great product and experience ordering with you.

Eric, just a quick note to say thanks to you and your staff.

The inserts arrived safe and sound (well packaged). They were sized exactly to our measurements and they fit perfectly. Very easy install.

Immediate difference in each office after install. Not only was there no longer a draft coming from the windows but the rooms were noticeably quieter. Even with outside temperatures around freezing, Rusty and Jim did not have to turn on the small heaters they used in trying to combat the chill from the windows.

Got our window inserts today and they are so awesome. I can’t believe how quickly you were able to get them made and shipped. Thank you so much for your attention to our order and making such a superior product. We are delighted.

We received the inserts late this afternoon and have installed them. They were perfect! Thanks for being so speedy. We will be passing on information to friends and neighbors, hoping they will order some, too.

You guys totally exceeded expectations in how quickly you built and shipped them. And they're great. They're easy to install and have made a noticeable difference in the comfort of the room they are in.

The inserts are in and they are FABULOUS! The moisture is almost all gone, they look perfect and boy did they stop the breeze.

You are awesome. Thank you so much.

Energy Saver Window Inserts are a great solution for historic homes. Without destroying the integrity of our home's architecture, we have eliminated window drafts without going through the expense of custom window replacement. Also, EnergySaver offers exceptional customer support when you need it. I have recommended this product to my friends.

Just wanted to let you know how happy we are with our new porch window inserts...they fit perfect, look great, and so far have stood the 20mph wind test!

We will probably be ordering more for other windows in the house.

Thanks Again!

I installed those window inserts on Saturday morning. Those are amazingly clear. I was impressed with how easy they were to install. Need to do some measuring and get pricing for my other 6 windows I want to do.

Thanks

I am so STOKED about how awesome these inserts are! I can already tell my oil fueled heater is NOT cutting on as often nor is my A/C! I’m so excited to see what the first bill is going to be…the weather has been below 60 a few days and above 75 on others so it’s been a bit unpredictable and I have to keep my home temperature about 70 all the time so I just switch to heat or A/C as needed but neither of the two would kick on, NOT AS NEARLY AS MUCH AS LAST YEAR!! It’s AMAZING! I’m definitely pleased and so grateful for the time and attention you gave me as your client. I plan to spread the word about your product with every opportunity I have! The shipping packaging albeit it was large, was light weight and not cumbersome at all….the installation was SO EASY!

I received the starter today. It’s just as the testimonials describe. Plan on receiving the order for the balance next week.

"We received and installed the inserts yesterday. They fit perfectly and have made an immediate difference. Our condo is noticeably more comfortable. I have already recommended inserts to friends and neighbors so hopefully you will see more orders from Utah.

Thanks so much."

I have to tell you that I've lived in my house for 10 years and every summer our bedroom is easily 5-10 degrees hotter than the rest of the upstairs (it has 9 huge windows and faces west) and freezing in the winter. Since I installed the inserts, the room stays as cool as the rest of the house and is infinitely more comfortable. I didn't believe it could happen. I can't wait to see what happens when it gets over 100 again. Thanks so much! I'll be ordering more.

Forty one month’s (3 1/2 years). That's how long I have had my EnergySavr Windows. In February of 2009 I was under pressure to do something about our energy cost. In December 2008 and January of 2009 my electric bill was hitting $500.00. That was not sustainable. So I when to work on the house to make it more energy efficient. More insulation, fix doors, leaks, etc, etc. But the biggest problem was our windows. We have seventeen windows in the house and replacing them at that time was not an option because of the cost involved.

I got lucky thanks to the internet.

After researching for hours about how to shore up my windows to make them more energy efficient without replacing them, I ran onto the EnergySavr web site. Wow, this sounds interesting I said to myself. If inserts placed into my windows could create a dead space between the window and the insert creating a high ‘R’ fixture, that might do the trick. The cost was reasonable and the company was willing to send me a sample insert for proof of concept.

They worked great. I have reduced my electric bills to under $200. The inserts were the biggest part of this change.

I live on a lake in east Texas. My house faces north and I have 12 windows looking out at the lake. In the winter, cold fronts come across about 10 miles of open water and right at my house.

After several winter seasons of having a cold and drafty house and high energy bills, I purchased window inserts from Energy$avr. The order process was very easy and the installation was a snap.

I have had the inserts for 2 winter seasons and my heating costs have been reduced each year by about 30%...

If you have leaky windows and are tired of a cold house and high energy costs, I highly recommend installing window inserts from EnergySavr.

We received our windows on Friday. We couldn't be more pleased. They're AWESOME! Not many good things give immediate results, but these inserts are the exception. We felt the chill magically disappear at the time of installation! Again, AWESOME!!! Congratulations to you guys on creating a useful product that beats anything on the market. ( I feel like I've considered EVERYTHING).

Not to mention we'll be telling EVERYONE we can about the windows. I would say that I'm looking forward to next winter, but that'd be an overstep :)

Take care and I hope you guys have a prosperous 2012.

I own a modern retail shop that has a large storefront with commercial single pane glass windows from floor to ceiling. Being in the Pacific NW, our heating bill was significant. I had spoke with several commercial contractors to find solutions for additional insulation; the responses were hopeless from financial feasibility. I discovered Window Inserts and after speaking with Eric, send him my measurement and order with some level of skepticism. We received the materials, very well packaged. We installed the panels, some of which were very large: 62" x 75". But the panels-frames were strong, rigid and aesthetically matching to the existing window frames, the foams around the edges gave us enough room to snugly fit the panels, and the measurements were impeccable. We installed a 21' x 10' wall of panels in less than 50 minutes with two people and a puzzle of panel sizes without any glitch and it looks terrific!

The transparent film, while soft to the touch, did not create any noticeable visual distortions and did not sag even when exposed to bright sunlight and the room temperature reading 95 degrees -- I had to test it! Eric was pleasant to work with on pricing.

My wife and I live in North Dakota in a house built in the 1920s. We knew we had to do something with the windows since they are original to the house,and how cold our winters get. I searched online and found your EnergySavr Window Inserts website. I ordered a starter window, and after the easy install we knew this product would be a good option for our house and budget. We were impressed with the fast shipping and the friendly customer service. We recommend this to anyone who wants to be more comfortable in their house and save money.

Your window inserts arrived yesterday. They are FABULOUS! The clarity is better than I have ever seen in "plastic film" storm windows. We really appreciate your one on one working with me and the quality and timeliness of the final product. Please tell your workers how happy and Satisfied we are with your products.

I'd been looking for a way to add insulating effectiveness to my Andersen Windows and came across your site as I could not find anything on the market that would not void the warranty of my windows. Living in Maine, we're always looking for ways to keep warm. Thank you for the product you provide. It is truly ideal, works great and the inserts are extremely easy to use and look great. The craftsmanship is excellent and your service and timeliness in shipping is exemplary. I will refer you to all my friends; I think your product is wonderful.

Thanks so much for the window insert. We received it in good condition. Before ordering more inserts, we thought it would be interesting to see what the Energy audit people had to say about them. The audit involves sucking all the air out of your house and then looking for places where air is seeping back in. They said the insert was doing a fabulous job and they would recommend getting those instead of replacing the windows...

The Energy guys said they had never seen anything like those before. We gave them your information so they might turn out to be valuable marketing agents for you.

We bought a bunch of window inserts about four years ago for our 1880s KY farmhouse and have been meaning to get back to you on how pleased we are with them. They are holding up great and they make the place so much more comfortable in the winter, even with the original blown-glass windows still in place.

I received the window inserts the other day and I placed them in the window and they fit perfectly! What a difference they make. It is much warmer in the room now. Thank you so very very much. My plants are happy and I am happy that that chill in the air is gone now. : )

Thank you!

You were right, the installation was quicker than opening the box (very good wrapping)!

THEY FIT! We are having our first chilly October week and I can already feel the difference.... AND, I won't have to wear 4 layers of clothing with a blanket when I sit on my couch, and will no longer have to dive under the bed covers, dreading coming out to face the drafty winter cold.

Much Thanks,

The windows were great as expected! What was really amazing was that I left the inserts place while I went to buy some weatherstrip and when I got home as I pulled the inserts out, the air behind them was really cold. It was cold standing in front of the old windows while I put them in, and then of course, no draft, it was great. It got into the 40's last night and is low 60's today and the electric heat is set at 69 and has not come on yet. I have a good feeling that with the condition of my 200+ year old house, these windows will save their cost in electric in the first year. The rest of the house is well insulated, it is just the widows that were killer. I am really glad I did not do sash packs now as this would have really ruined the beauty of the old glass. Plus the comfort factor and noise reduction is a huge plus. I am working on some more sizes for the upstairs next door and also a neighbor of mine, so I will be with you again shortly.

Thank you for the quote. I do totally understand why you bought half the company after seeing them work... I've experienced their awesomeness in my mom's house and have to agree they're amazing!

Be my guest in using my quote, and who knows I might even have additional customers for you once my family sees how well these inserts work. I don't mind spreading the word on a quality product that actually works as advertised.

I received the starter insert in one piece yesterday, which by the way was packed very well. It fit perfectly, and it performed well. We had a cold spell last night, temperatures down to freezing, and this morning, every window in the house was sweating, except for the one with the insert in place. I am very pleased with both the performance and construction of these inserts, I am SOLD! I will be sending you payment today for the remainder of the order.

I wanted to let you guys know that I received my first electric bills since my installation. Given that the 2 month period was riddled with colder than normal temperatures and a snow storm, I saw significant savings of at LEAST 200.00 of my bill.

We purchased these window inserts for every window in our house and it has been one of the best decisions we have made. We absolutely love them! Our house was immediately noticeably warmer and much more comfortable to live in. The customer service we received from Eric was exceptional. He patiently worked with us in answering all our questions in a timely and professional manner. We put these inserts in a new house where the windows we chose had considerable cold air coming up through the tracking. Living in Wisconsin winters would have been far less enjoyable than they will now be with these inserts. Nothing comes through these! We would highly recommend Eric and his company to anyone looking for ways to be more energy efficient with today's heating and cooling prices.

Just a quick note and question... These inserts have really made a difference in my house.. with the excessive winds this year in the Northeast as well as the cold the inserts have really made my house much more comfortable. I will note in the spring my savings in fuel.

hey, these inserts are really nice - we've noticed how they have cut out the "breeze" from our windows. thanks again - great product.

I have used these inserts thru one of the coldest winter stretches on record for Georgia and am very pleased with them. I think they are saving lots of heating fuel for me. I am very pleased with the inserts. I'm trying to get my neighbor to order some as well.

I thought you would appreciate some feeedback...

Just installed most of the inserts, and the ones I handled are perfect.

The only issue was that the shipping co (RL) was slow to deliver the last leg...failed to show one day....

This is a great product and should have been pushed by Obama with that "insulate your homes" initiative. Let me know when I can buy stock in the company :)

Best Regards.

I ordered 4 inserts nine days ago. They showed up in 8 days. It took longer to get them out of the box than it did to install. I am anxious to see how I like them...some colder weather on the way for the weekend so I should know soon! If they perform like I think they will, I will keep them in mind for some customers of mine. I assume that you already know that they look great! Thanks!

How it going in the warm south??? Here in fargo it is the winter of the century with no temps above 10F. As you know I put the inserts in every window of my 2,000sf, 10 YO rambler because last year I had ice buildup on the inside of the windows on every pane to the point the wood was waterstained. This year with the inserts installed (by me) I have ZERO moistrure on the windows. Cant wait to see my heatin bill which was over $400/mo last year w/o the inserts.

The inserts came beautifully packaged and they are wonderful. They fit just right and we can feel the difference. We have other windows to deal with and I am sure we will be ordering more. Perhaps I should invest!!
