Why It Matters

Hidden above the ceiling, out of sight

Cassette units collect mould, dust and bacteria on the evaporator coil, fan, drain tray and internal surfaces. Because much of this build-up is hidden above the ceiling, the unit may look clean while still producing musty odours, weak airflow, water leaks or reduced cooling performance. A thorough clean removes this internal contamination and restores airflow and cooling efficiency.

Signs your cassette unit needs cleaning

• Weak or uneven airflow across the room
• Musty, stale odours while running
• Visible dust, mould or debris around outlets
• Water dripping or staining around the unit
• Reduced cooling or longer running times

Before and after: cassette unit cleaned

How often should you clean your cassette unit?

Generally once every 12 months for most properties. If the unit is used very frequently, or the environment is dustier or more contaminated, every 6 to 9 months is a better guide. Commercial systems typically fall into this shorter 6 to 9 month range too.
