Overview
Exiis provides specialist HVAC duct cleaning, air handling unit (AHU) cleaning and coil cleaning services to commercial buildings, healthcare facilities, defence establishments and government properties across South Australia and the Northern Territory. Our services are designed to maintain indoor air quality compliance, extend system lifespan and support the health and productivity of building occupants — with full inspection reporting and compliance certification provided as standard.
Why Regular Maintenance Matters
- Poor indoor air quality is directly linked to increased illness, absenteeism and reduced productivity — a significant liability for employers and facility operators
- Contaminated ductwork circulates dust, bacteria, mould spores and airborne pathogens throughout occupied spaces — a critical concern in healthcare, aged care and education environments
- AS 3666 sets mandatory requirements for the maintenance of air handling systems in commercial buildings — non-compliance creates liability exposure
- Dirty coils and AHU components reduce system efficiency, increase energy consumption and accelerate component failure
- In healthcare and food environments, contaminated HVAC systems pose direct infection control and food safety risks
- Proactive maintenance prevents costly emergency breakdowns and extends capital asset life
