“Wonderful!”

5 / 5

American Thermal did a wonderful job on my projects! I had 2 doors, a window and 2 awnings replaced. Linda was wonderful with helping schedule, plan and manage appointments. I really depended on her! Igor and Jim are master craftsmen and Jacob was an enthusiastic and able helper! They were always on time and cleaned up after themselves. I’d definitely do another project!

“Quick & Clean”

5 / 5

“American Thermal recently installed our new windows ahead of schedule and completed them on time. The installers, Igor & Vassil, showed up on time, finished the job on time, and did a very good job cleaning up all the debris.”
