Introduction to Residential Duct Cleaning

Residential duct cleaning is a growing service category within the Australian home services sector. Dirty ductwork degrades indoor air quality, reduces HVAC system efficiency, and — in the case of dryer duct systems — creates a genuine fire hazard. This course introduces the business context, technical knowledge, and equipment operation skills required to provide professional residential duct cleaning services. Topics covered: the commercial opportunity in residential duct cleaning, residential HVAC system architecture, the two primary cleaning methodologies (contact and negative pressure), the specific equipment systems used in each methodology, and the end-to-end cleaning process. This course is in Draft status. Content reflects the current module framework and is subject to review and supplementation with practical field photography and video resources prior to final publication. Standards applied: AIRAH (Australian Institute of Refrigeration, Air Conditioning and Heating) technical guidelines, AS/NZS 3823 (performance of air conditioners and heat pumps), Safe Work Australia Model WHS Regulations, state fire safety regulations applicable to dryer duct systems.
