Planning the Job

Planning the Job

Planning a duct-cleaning job requires the use of accurate mechanical drawings of the duct system.

Drawings serve as a valuable planning tool and a map for the job itself. Drawings are used to identify coils, turning vanes, access points, and to establish cleaning zones. Duct cleaning is generally performed in zones of about 25' (7.6m) or less.

Some types of duct cannot be cleaned using these the cleaning methods described here. Uncleanable types of duct should be identified at this stage. They will need to be removed and replaced. (Most flexible duct and certain lined ductwork cannot be cleaned without damaging the ducting.)
