FURNACE & DUCT CLEANING METHOD
Here at Dang Good we use the Push Pull Negative Air Pressure Method as recommended by QUADCA. Air is compressed at 250 PSI. The Negative Air Pressure creates a powerful pull. Our technicians will start the cleaning process with the vents furthest away from the furnace and gradually work their way towards the furnace. As dust and debris is pulled from the vents by the negative air pressure, other tools are used to push and agitate the dirt and grime simultaneously. The dirt will be forced into the main trunk line of the Duct System. It is then sucked in to the large powerful vacuum which is attached to the furnace by the Cleaning Technicians at the beginning of the cleaning process and subsequently removed from the home.
