I received the 4 window inserts today. They fit beautifully , and have a great sealing ability. I already notice that it is more quite and feels better insulated already. I know it will really cut down on my heat and cooling bill. . Let me know when you start selling stocks, I will definitely buy some. You make a great product and it shows in the quality of the inserts, and the superb way you package and ship them. Great work. Thank you

Customer service is outstanding. Received my order of six large inserts in 8 days. They all fit snug. Have a skylight in kitchen and placed one there as well as the window over the sink. The kitchen not only felt warmer but the thermometer showed a 2 degree increase in temperature within three hours. Follow the on-line instructions and you should have no problems. Only drawback are the color choices. Maybe an almond or beige color to cover all the bases. Fantastic product.

I live on a lake approx. 90 miles north of Houston, Tx. My house faces north and has 12
single pane windows across the front that give me an unrestricted view of the lake.
Natural gas is not available where I live, so I have electric heating.

In 2009, I experienced several "blue northers" (cold fronts from the north) that resulted in very high electric bills (over $500 a month for three months)
I considered double pane windows to replace the existing windows, but every cost estimate I got was in excess of $3500.00

I searched the internet and found the window inserts and purchased 12 inserts in 2010.
Since installing the inserts, my heating bills have been reduced by approx. 50%.

I highly recommend using these inserts to lower your heating costs.

I am over the top happy with my Energy Saver window inserts!!!
They have solved the problem of trying to keep a mid-century modern house warm. It is essentially a glass aquarium with large single pane windows.
It was impossible to heat or cool and prohibitively expensive to replace the windows..
I happened on this site, read all the reviews and was impressed enough to order a sample window.
The quality was excellent, gave it a trial run and ordered windows for the whole house.
The ordering process was easy and help is only a phone call away. The windows arrived as promised and were well packed.
We made an error on measuring one window, called Customer Service last Thursday afternoon and got a call today (Monday) saying the replacement was shipping today and there would be no additional charge.
Customer Service is Superior.

Thanks to everyone at Window Inserts I am now warm and am looking forward to being cool come summer.
PS
I know my energy expenses will be lower because my heating system is not running constantly.

Thanks again,

Carolyn,
a very satisfied customer!

the initial test windows that i ordered immediately eliminated the drafts from the windows that i covered. i went back to eric and jessica and ordered more for the whole house.
the product does do what the company says it will do. i live in the north east in a 1970's home. my windows have been very drafty.
i am only sorry that i did not learn about this product sooner i strongly suggest that this product be used in any home. the inserts look perfect and blend into the window. even my wife likes them

we have a 1920's home with original windows.the walls and attic are insulated very well but the house was still very drafty. we bought 18 inserts for the first and second floor. What a difference it has made. No draft at all, not even the draft that used to blow down the steps. I highly recommend this product. We live in south central Minnesota. Thank you Eric.!!!! you were great to work with!!

Those arrived and they are GREAT!!! VERY helpful for our air infiltration in our 1853 house.

Thanks for sending them! I wish I’d ordered them sooner and instead of the 5 x more expensive magnetic interior storm windows. The magnetic ones are excellent, but not sure they were worth that much more money.

Thanks again!

Bought and installed 10 inserts several months ago. I live in North Dakota where cold and wind is intense and these have helped greatly with draft from windows and heating bill.

I live in Northern Ontario, Canada and as I could not find a similar product in Canada, I decided to purchase inserts from Energysavr. I did a trial of 11 windows. Unbelievable product! -45 celcius and no drafts. House nice and warm. Excellent product. Received personal phone call as well. Customer service above and beyond. Thank you for making a great product

I purchased these inserts without my husband's knowledge and this was the BEST money I ever spent. I have had the inserts in for only 3 days, put them in myself, and the difference in temperature near my huge bay windows , each 93 inches wide, is barely perceptible, I came home to a power outage, temps in the teens, and my house was still warm. I intend to purchase inserts for the rest of the windows in my home. Thanks for such a wonderful product!

Very pleased with our new window inserts—no more chipping ice off the steel window frames, no more pools of water on wood window sills, not to mention the dramatic drop in cold air coming off the windows.
Thanks,
Syd

From the get-go Eric was upfront, very helpful, and knowledgeable about taking measurements and the process of shipping out the window inserts. I'm the kind of person who would rather talk to somebody on the phone then fill out an online form, and they were very accommodating.

I received the window inserts today and have already installed them. Our home is in a historic section of Beacon Hill in Boston so we are restricted as to what we can install. These window inserts cannot be seen at all and have really cut down on the drafts through the old window sash. I would recommend this product.

I installed 57 window inserts in my home a year ago.

I have been in my home 50 years. In winter the north wind would blow thru cracks around windows.

After installing window inserts fitted perfectly to each window my house has no drafts. It is like being in a warm nice cave.

We just installed our window inserts and love them! I'm pleasantly surprised at how nice they look.

We were looking for a low cost solution for an old drafty single pane picture window in the back of the house. We didn't have that window replaced when we did the rest of the house, because we're planning an addition in that area. These inserts are the perfect solution for us. They look great, stop the drafts, and help control the room temperature. I can't get over how good they look. If the vinyl film stands the test of time, they'll have been well worth the price.

There is no doubt I can attribute the savings I saw in heating costs this past winter to these inserts, especially since this area had the coldest January-March on record. They have half paid for themselves in just the first winter. Sure, they're not "cheap", but you get what you pay for. Excellent workmanship and super packaging ensures their safe arrival. And clarity? You hardly see a difference looking out the window when they're in place.

OUTSTANDING! Bought them last year and tried them out this winter 2014-15. Heating bill lowered and rooms were noticeably warmer. And I was skeptical but no more!! Would highly recommend!! Absolutely!!

We bought our inserts over 10 years ago. Since then I am sure we have saved significantly on our energy bill. The inserts have held up very well and show no signs of breaking down. The foam has become a bit compressed of course but I think that must be normal. I brought an insert in for replacement to Eric recently ( I very unwisely used a softscrub product on it : Don't do this BTW !!) and he replaced it at a very minimal charge even though it was way past warranty and was totally my fault. Thanks for the great product and customer service!

I am very glad that I purchased these inserts for the 14 windows we have in our home. Especially because of the winter we had this past winter (2014-2015). The inserts helped keep my heating bills low, and our home nice and cozy. Thank you everyone at Energy/$avr (windowinserts.com). Keep up the good work.

I love my new window inserts! Now I can look out my windows without having them covered to stay warm. No more drafts! Looking forward to my seeing my new heating bill. Thank you

I am thrilled with this product. I have a home that was built in 1898 and then cut in half and moved around 1990. Totally restored but the windows are original if not to the house to the period. All are out of square and I do not want to ruin the integrety of the house with replacements. Plus I have read that replacing the windows doesn't necessarily solve the issue as it can create more airways if not properly done...ie. custom windows.
I bought 8 to begin with. Then I ordered 4 more plus inserts for my 3 fireplaces. I messed up on the measurements and Eric has been extremely helpful in finding a cost effective resolution. My next order will be for inserts to use on the 7 exterior, wait 8 exterior doors. I am hoping that next winter my propane costs will be less than $500.00 per month!
I highly recommend this product. They are cost effective, easy to use, esthetic, and efficient!

Just wanted you to know that the window inserts fit perfectly and have made a big difference on our picture windows. They have decreased the cold air in the rooms and have allowed us to decrease the amount of fuel to heat the area.

We would highly recommend them.

The winter is serious up here in the Colorado Rockies, especially living in an 1888 house with original windows. The inserts cut our heat bill by at least 30% to 40%. We'd freeze without them!

I just wanted to let you know that the window insert is doing a great job insulating our room against cold and dust. It is particularly helpful now as we live through blizzard Juno.

We got these inserts for our restaurant in Canada because people always complained of the cold draft in the winter. We tried EVERYTHING and nothing worked until now! And we just bought another restaurant and got them there too! Great customer service too from Eric!
