How to Maintain Your Split System for Year-Round Performance

Maintain Your Split System Peak Performance with routine cleaning and periodic professional checks. Consistent care keeps air fresh, energy use low, and reliability high.

1. Clean Filters Regularly

Vacuum or wash filters monthly in peak seasons. Clean filters improve airflow, capacity, and indoor air quality.

2. Keep Coils and Louvres Clean

Wipe indoor louvres and schedule coil cleans to remove dust and biofilm. Clean heat‑exchange surfaces transfer energy efficiently.

3. Clear the Outdoor Unit

Remove leaves and maintain 300–500 mm clearance around the condenser. Unobstructed airflow reduces compressor strain.

4. Check Drainage and Odours

Ensure the condensate line drains freely; investigate musty smells promptly. Early fixes prevent water damage and mould.

5. Book Annual Professional Service

Have a technician check pressures, sensors, electrics, and firmware. Pro servicing catches small issues before they escalate.

Pro Tip

Set reminders at season changes for filter cleans and a quick outdoor unit inspection—small habits pay big efficiency dividends.
