Give them a call you won't regret it!

I have now had ATW out for 3 separate projects (patio door, roof/skylights and windows). I tell everyone that "I gotta guy" for windows and roofs. I love this Company. Their pricing is great, workmanship is excellent and they keep their appointments (Unlike a couple of their competitors). My windows, roof and door look great and my energy bills have gone down. Give them a call, you won't regret it!

Job Well Done

We had 13 windows installed over a year ago and they were the best purchase we ever made. Salesman Eric showed us all of the options for our type of house and was honest and fair. The windows are of high quality and have withstood two Chicago winters with no problems. The laborers were clean and quick inside our home. The job was finished in one day and they matched the existing siding on the outside trim. We live under the O'Hare runways and you can barely hear the planes- an added bonus to the job done well by this company. We recommend them to everyone!

Beyond Satisfied

After having all the windows on my house replaced by American Thermal I was so appeased, that I had Iver and his crew replace the 100 plus year old windows on a twelve unit apartment building that I own. My only regret is that I did not have the windows replaced sooner.

they know their business

I've had a number of dealings with American Thermal (and personally with Iver and Iver,Jr) over the years. They not only know their product(s), but stand behind them. Their prices are fair, their work crews both knowledgeable and friendly, and any need for service of any kind is responded to very quickly. The products themselves are tops. It's easy to recommend a fine company when it's being run by good people.

Iver and his team were great. All my windows were installed professionally and on time. I have used American Thermal for years and have recommended them to friends and neighbors.

Great service/Great product

Not only was the service from Iver and his team outstanding, my windows and door replacement was done on time ( sales even came during the day to check the job) and followed up to make sure everything was up to standard. The windows have been in a little over a year and I have over a 30% reduction in my gas bill.
Thank you!!!!!

Great product

Iver Jr really knows the products well and helped me with picking a style of window that would best fit my home. The Installers did a great job. The windows look amazing. Not only that, my gas bill has decreased significantly. I was very satisfied with my experience with American Thermal Window.

Great people, great service!

American Thermal took out a window and exterior wall, and replaced it with beautiful floor to ceiling french doors, going out to a new patio. They did the work in a day, very reasonably priced, and the finished product was fabulous. We had a problem with one of the internal blinds and they came out and fixed it the day after we called for service. They are professionals and very easy to work with.

My wife and I had all our windows replaced by American Thermal Window shortly after moving into a home which was fitted with poor quality windows. The previous windows were installed in 2001 by the previous owners and cold air would come right thru them. When we called the company to inquire about warranty work they informed us they do not service that line of windows!

We met with Iver Jr who came to our home for an estimate for our 12 windows. He was very professional and not pushy at all. We decided on their Great Lakes window with triple paned glass. We signed the contract that night and were told it would be approximately 6 weeks for the windows to come in.

We received a call just over a month later to schedule the install. We had a two man crew who arrived at our home around 8am. They were very polite and clean as could be. They completed the 12 windows by the end of the day, and you could not tell they were there, other than the new beautiful windows we had! They placed drop clothes everywhere, vacuumed afterwards and even took the stickers off the windows and windexed them! We were impressed!

We couldn't be more pleased with the whole experience! If you're looking for windows this is the company to call!

Amazing Product

These guys have the best product IMO.

Best Service in Illinois!

Beyond satisfied. Iver, Sr. and Iver, Jr. blew my family and I away with their impeccable service! Thanks American Thermal Window!
