エアダクトクリーニングの手順

To allow a building's air duct network to 'breathe', it is necessary to remove the congestants: all the dirt, dust and debris that has accumulated inside the air ducts over many years.

Mold spores, mildew and bacteria love dirty air ducts and thrive in them. Dirty ducts can also result in higher utility bills, reduced air supply and premature failure of expensive HVAC components.

At Microdust, we follow the The National Air Duct Cleaners Association's recommended guidelines for cleaning using Source Removal methods. The procedure is efficiently completed in four steps:

1. Provide coverings to protect work area's facilities, furniture, flooring and décor against dust and debris before commencing cleaning services.

2. Containment engineering control: Create isolation barriers/ negative pressure in the work area to prevent the unintended migration of airborne particulate into other non-working area.

1. Install access panels in duct system to facilitate cleaning if necessary.

2. Dismantle and clean all air diffusers/grilles, and reinstate to their original position at the end of the job.

Perform air duct cleaning processes according to NADCA standard. Cleaning techniques employ various pressurized air sources plus other tools and equipment to dislodge attached particulate and debris and convey it to a HEPA filtered collection device in a safe and controlled manner.

1. Treat the cleaned air duct interior surfaces with the sanitizing and deodorizing agent.

2. Clear job site after completion of works.

3. Submit report together and photograph/video record on condition of air and interior surfaces taken before and after services.

Different project varies from one to others, please seek Micordust's consultant for specific work
procedures in order to suit your application.
