It is such a great feeling to know our duct system in our home is so clean now. Our home was built in the early sixty's. We have had it for seventeen years and had some minor dusty renovations done. I was concerned with our air quality from the years of accumulated flotsam and jetsam. The AIR...

Since they tried to clean my air vents, dirt has been collecting all around the house. Mainly in the kitchen and in the bathroom area. They call it branch return air ducts. They charged me $100.00 dollars for each vent and $49.95 for the main air supply duct.
