Maintenance Tips
Simple Tips to Avoid Unnecessary Breakdowns
Often, issues can be prevented or easily resolved at home. To help you avoid avoidable service calls, here are some key maintenance tips:
00
Know When to Replace Your Filter
• If the filter looks worn, torn, thin, or misshapen, it’s time to replace it.
• A damaged filter can’t trap dust properly and forces your AC to work harder.00
Check Airflow Around the Unit
• Ensure there’s no furniture, curtains, or dust buildup blocking vents or the indoor unit.
• Good airflow helps your system cool and heat your home more efficiently.00
Use Correct Cleaning Methods
• Do NOT use a vacuum — it damages the filter fibres.
• Rinse with a hose using low pressure to avoid holes.
• Wash the filter opposite to the direction of airflow.
• Let the filter dry for at least 5 minutes before placing it back.00
Seasonal Maintenance Reminder
Use the four seasons as a reminder:
• Winter → Spring → Summer → Autumn
• Clean your filters at least once during each season to keep your system running smoothly.00
Before You Call for Help

• Is the filter clean?
• Are the settings correct (cool/heat, fan speed, mode)?
