Steam Dry Canada

We had our furnace ducts cleaned several months ago and although the tech was friendly he appeared to be in a rush. During the following months we noticed that our home was unusually dusty, so when I went to replace the filter I noticed that the Tech didn’t replace the one he removed with anything. When I contacted Steam Dry Canada they showed NO interest in taking responsibility and said that it is the customers responsibility to bring it to the company’s attention within 7 days of the work.
