Why It Matters: Aussie Offices, Real Consequences
From heritage terraces turned co-working hubs to glass-clad towers, all offices need reliable, clean AC. Neglect can:
- Increase sick days from poor indoor air quality
- Spread dust, bacteria, and mould spores
- Raise electricity bills by up to 30%
- Overwork systems and cause early breakdowns
If you manage buildings or facilities, routine AC cleaning is part of your duty of care.
How It Works: What’s Going On Inside Your AC

Commercial splits run longer and serve more people than residential units. Common grime points:
- Filters: Dust, lint, pollen from recirculated air
- Evaporator coil (indoor): Mould risk in humid rooms
- Drain tray & pipes: Algae and blockages cause drips
- Fan blades & casing: Dust reduces airflow and efficiency
- Outdoor unit: Leaves and smog residue clog fins
Many office head units sit high on walls or ceilings—cleaning needs proper containment to avoid mess.
Aussie Tips: Smart Cleaning for Busy Sites
- Use a commercial cleaning bag: Wraps around the indoor unit and catches coil-cleaner runoff—no mess on carpet tiles or desks.
- Choose specialised coil cleaner: Skip household sprays; use professional HVAC cleaners designed for fins and plastics.
- Stabilise access: Use a ladder stabiliser or mobile scaffold for high installs.
- Handle panels gently: Older fascias crack—use a soft cloth and take your time.
- Check manufacturer specs: Follow Daikin/Fujitsu/Mitsubishi guidelines to protect electronics.

Maintenance Must-Knows for Building Managers
- Quarterly filter check: More often in carpeted or high-traffic zones.
- Bi-annual coil clean: Before summer and before winter.
- Monthly visual inspection: Look for dust build-up, odd smells, or weeping drains.
- Clear drain lines: Algae in condensate lines causes ceiling drips.
- Log everything: Keep a maintenance record for warranties and staff queries.
When to Upgrade: Warning Signs
- Persistent odours after cleaning
- Rising power bills with no clear cause
- New noise or vibration from the head unit
- Uneven temperatures across rooms
- Units 10–15+ years old without inverter tech
Modern splits with energy-saving modes and anti-mould features often pay back in lower running costs.
