Ventilation Deep Cleaning
HVAC servicing should include more than just filter changes. Our Ventilation Deep Cleaning service targets all internal surfaces downstream of the filter bank, helping maintain airflow efficiency, reduce hygiene risks and extend system lifespan.
What is Ventilation Deep Cleaning?
Ventilation Deep Cleaning involves the thorough chemical cleaning and sanitising of your HVAC system – from the external air intake right through to the internal air supply grilles. Our technicians clean and restore all internal surfaces within the ventilation system, including ductwork, fan rooms, registers and condensate trays. We also repair damage such as flaking paint, rust and deteriorating seals and filter holding banks as required. We also offer antimicrobial coatings after cleaning to help prevent mould regrowth.
Key HVAC components cleaned and sanitised include:
- Outside air intake louvres
- Filter rooms and holding banks
- Air supply fan and fan room
- Heat exchange coils
- Air supply ducting
- Registers and ceiling grills
- Condensate drain trays and pipes
