Product reviews: Easy Order Window Inserts Online

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

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.

Amazing!!! My daily power usage was $24.00.
After the inserts, it is $10.00
They just paid for themselves.

Eric, you’re a genius, man! Your shipment arrived damage free, and the installation was a piece of cake. I just installed 13 window inserts in under and hour, and most of that time was devoted to working around the shades and curtains to gain access to the window openings. Many thanks for a great engineered product and your fine customer service.

My wife and I recently received 30 inserts, and we are delighted by them. Each one fitted easily in the space it was made for, and we could instantly feel their effectiveness. The service you provided was excellent, and we can highly recommend these interior storm windows to anyone living in a cold climate!!

I recently ordered 5 of your window inserts for my basement egress windows that are “exposed” to daylight. I received them today and installed them. They fit perfectly and were very easy to install. I could tell a difference as soon as I put them in! The drafty air stopped immediately! We will be ordering more for some of our “West” facing windows in the upstairs. Thanks for a great product, lightning fast shipment and saving us money on our heating bill!

We received and installed our 18 window inserts back in October and installed them just before the cold winter hit Downeast Maine in November. Since mid-November, it has been unusually cold here, average temperatures in December at least 5 degrees below normal. The inserts have performed wonderfully; indeed, I don't know how we could have survived in our old, un-insulated farm house without them. You have a great product, and you handled our order and delivery with a very high degree of competence. Many thanks!

I've had my Windowinserts for a year now and can now give an honest review of the product. Working for a utility company, I'm always looking for energy efficient ideas and products. From my first contact with Eric, to delivery and fit, Windowinserts have surpassed my expectations. Living in a 2 story house, there used to be a distinct temperature change when walking from the kitchen into the living/dining area. Both areas have large double pane windows, and used to feel the cold radiating from the glass, but no more. We recently had a cold snap, with temperatures dropping below zero, and there's still wasn't any cold radiating from the windows. What a difference! Upon Eric's recommendation, I left the inserts in during the summer, finding it easier to cool the house as well. I highly recommend Windowinserts for anyone frustrated with cold, drafty windows, as a cost effective alternative over replacing existing windows. Thanks so much and keep up the good work.

The inserts are holding up really well. I have used them each season for the last three winters. Although the material appears light-weight, it is actually quite sturdy. The temperature difference at the windows with the inserts is very noticeable, and the room stays much warmer than it would be otherwise.

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.

Tried 1 window last year on a window we could not keep plastic on even with duct tape. These actually work. better. then I thought they could. Ordering the rest of Windows this year.I know they can stop a 40 mph wind

100% on website, customer service, delivery, and utility! I ordered a test insert for an old window installed in 1888. It was delivered 2 days early and packaged extremely well. I unwrapped and installed the insert in a few minutes - it fit perfectly. The view through the window remained the same and friends couldn't see anything different. I will be ordering inserts for many more windows. I am so pleased with everything about this product.

Love these inserts. They took about 3 minutes to install. Easy, nicely and a perfect fit!

I just got my replacement inserts.

I want to tell you that your company has incredible customer service. I have enjoyed every facet of this experience.

I have a smart thermostat in my bedroom that I can use to track furnace run time. The first night I installed the inserts, it was 10 degrees cooler than the night before, but the furnace ran half as often.

I will encourage everyone I know to try your product.

I ordered 4 of them about two weeks ago and got them in yesterday and they are amazing! I noticed a difference almost immediately! I plan on ordering 14 more tonight.

We purchased window Inserts for a rental property to maintain the beautiful windows in the home and to pass an inspection. The home was built in 1939 and has beautiful iron rod windows. To ensure the tenant would not be left with a drafty house, we purchased around 20 inserts. Let me start by saying the customer service is remarkable, professional, and knowledgable. The inserts fit perfectly and the house looks amazing and has decreased in the draftiness. We love the inserts so much, that we are in the process of measuring the windows in our home to alleviate the draftiness that we are experiencing. The inspector was so impressed with the inserts, that she is also going to tell other rental landlords about the alternative of replacing windows to maintain the home’s charm. The owner of the company is amazing and we recommend window inserts to everyone. We are so very pleased and happy with the product and look forward to experiencing the same kind of comfort in our own home.

My order was delivered today, right on schedule , packaged well and in perfect condition! It took me only about 5 minutes to install, they fit perfectly! I was quite impressed. I wish I had known of these a few years ago. I had some inner storms built by a local hardware, difference of night and day.
