"Great! Very impressed with the professionalism of this company. Men wore booties in the house to keep from tracking in dirt. I’m picky about that! My husband had watched a YouTube video recently on the proper way to have duct work cleaned. It just so happened, the men also followed the same procedure. They were courteous and answered all the questions we had."
