Cleaning Pros of Baltimore

First I call Sears for a Duct Cleaning Services who contracts out to these guys. The coupon obtained said 99.00 to clean up to 10 Vents. Once they arrived I was given a free inspection and estimate to clean my heating and AC Unit. $1,730.00. I declined and went with the Duct Cleaning. They pull out a Air Compressor and a Wet and Dry Vac. Any Dummy can see if you're blowing Dirt further into the Duct some will exit other openings. What are you vaccuming from the Ducts?? The technicians smelled like Weed. He told me it was a Black & Mild. I don't smoke but if you now walk into my place you would think I did. My Floors now have to be vaccumed and swept. My comforter has to be washed.
