“Helping homeowners understand NADCA’s recommendations regarding the process of air duct cleaning.”
Air Duct Cleaning & Sanitization will be the most complicated process as it includes several operational stages. Complexity of air duct system cleaning derives from UNLIMITED vents, returns and main duct lines connected to a single HVAC unit. First of all, the technician will get an access to the trunk line close to HVAC-unit as it is required by NADCA standard.
After that he will connect our HEPA vacuum to one of your main trunk lines. As OZON Air Duct Cleaning uses the negative air pressure cleaning method (the best and the most proper way to get all the dust and debris out of the system), our technician carefully seals return air vent. All return covers and floor vent grills will be removed and our technician will show amount of dust and debris inside your system before the cleaning process using our duct camera. Using ‘Octopus’ agitator connected to powerful air compressor with 200psi of air pressure all dust and debris is forced into the main trunk line where it is pulled out to the vacuum. OZON Air Duct Cleaning technician cleans return and supply branches while connected to the corresponding trunk line. This is essential, as it prevents blowback and ensures the quality of the job. Once the dust and debris have been forced into the main trunk lines, he makes 1” holes to insert compressor air hose with an air whip which loosens dirt from the duct walls and pushes the dust and debris to the vacuum. The technician will show you how your system looks after the cleaning, so you can have ‘before and after’ experience that is required by NADCA standard.
