Henry came to a home that had not been serviced since it was built over 30 years ago. He found a large tape measure in the process of his outstanding cleaning. We saw the before and after pictures, and were pleased that we finally called Ductworks to do this job. What most impressed us was our technician, Henry cut his finger (minor cut and didn't know he had it) and then discovered a few drops of blood on the hem of our curtains where he was working. He came and told us, I washed the curtains and all was good. A wonderful, honest man.
