Many company’s in Pittsburgh use negative air machines to push large volumes or air through the duct work. You would know if you had this done before if the air duct cleaner had to cut into the duck work in the basement to attach the negative air machine.
This is a commercial process for very large buildings. Hospitals, for example, have this done. But this process can’t clean the duct walls. So a person will be sent inside the duct work to wipe the walls of the duct work by hand.
Obviously this can’t be done in your home. The duct work is not that large and this the problem with using a commercial method of air duct cleaning in your Pittsburgh home. The duct walls are not getting cleaned! Leaving the problems you wanted solved, stuck in your duct work.
Another method some use alone or in combination with negative air is a small ball attached to a whip that randomly hits throughout the duct work. This is done with the hope of breaking some soils lose. This is very random and not a a true cleaning of the duct walls.
We use a brush system that is designed just for homes. The brush along with a high powered vac cleans the duct walls. This removes sticky soils like hair, dander, and dust that are stuck on the duck walls. And we never have to cut your duct work!
We then fog the entire system with a non toxic product that kills allergens, mold, mildew, bird flu, TB, and a long list of other nasties.
