I had two storm doors installed by American Thermal over the last few years. I'm pleased with the doors and the installer's. Nick was the last salesman I dealt with. He was very pleasant and knowledgeable. I highly recommend American Thermal. Robert Garza

You would think a Chicago based business knows it's a city ordinance violation to place lawn ads on the parkway. Please put the ads on your client's property on the other side of the sidewalk. It just makes the neighborhood look trashy. I removed it for your convenience btw.

We were very pleased with the service. The installation went quickly and smoothly, the workers were very competent and thorough and they respected our wishes. Communication with both them and the office was always prompt and courteous. We are pleased with the product and look forward to years of use.

Report
Needed two windows replaced. After cancelling the first meeting 30 minutes beforehand, I reached out to reschedule. When the person showed up, he was helpful during the meeting, and promised to follow up in 2 weeks with an estimate. It's been a month since the late November meeting. Never heard from him or the company again. I moved on.
