5 star rating

I recently had all new windows in my house installed, and I am extremely pleased with the outcome. I had explored other window vendors, but American Thermal came out on top for service, quality, and price. From the initial site visit to the day of installation, everything went smoothly. Bruno and Victor were incredibly hard-working, efficient, experienced, respectful, and friendly and were able to complete the job sooner than expected. I feel like I have a brand new house! I highly recommend American Thermal Windows!

Received many estimates to replace our windows but decided on American Thermal mostly because of the salesman Tom who really explained the difference between his window and the windows we had estimates on. There were so many things we never even knew or thought of till he brought it to our attention. After the windows were installed by 2 really great guys we have noticed such a difference that there are no drafts in the house and the house is so much quieter. Everyone we dealt with was wonderful and exceeded our expectation. Highly recommend this company. A+++++++++

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!!!!!

I had 33 windows installed by American Thermal. I went with their Triple Pane vinyl window by ****** and I couldn’t be happier. I really noticed the difference this last winter. I saved almost $100 month on my heating bill. Needless to say they are well worth my investment. Everyone I dealt with from the office staff, salesman and installers, were very professional and informative. I highly recommend them to everyone. I even got my parents to get the same windows and they are just as pleased.
