Air Duct Cleaning process should follow the "source removal method.” This method requires that the entire HVAC system be put under negative pressure while a technician loosens all contaminants in each vent. The contaminants are removed via negative pressure through a closed system, ensuring no dirt gets into the home. As industry recommends, out team will attach a high-power, commercial grade HEPA filter vacuum to your system, which collects contaminants from the system throughout the entirety of the service. The air duct cleaners will than systematically clean every vent, using the Viper Whip tool to ensure that no dirt is left within the individual ducts. After all material is agitated, the debris collected from the interior surfaces of the vents will be pulled out of the system by a vacuum.
