🛠️ Clean or Replace the Air Filter
A dirty air filter can block airflow, making your aircon less efficient and causing it to blow warm air.
How to Fix
- Turn off the aircon and unplug it.
- Remove the air filter and clean it with warm water.
- Let it dry completely before reinstalling.
- If the filter is damaged or extremely dirty, replace it with a new one.
Pro Tip: Clean your air filter every 3 months to maintain optimal performance.
❄️ Check and Clean the Condenser Coil
The condenser coil is responsible for releasing heat. If it’s clogged with dust and dirt, your aircon may struggle to cool properly.
How to Fix
- Turn off the power supply to the aircon.
- Use a soft brush or vacuum to remove dust and debris.
- Lightly spray the coil with water (avoid high pressure to prevent damage).
- Let it dry completely before turning the aircon back on.
Pro Tip: Keep the area around your outdoor unit clear of dirt and leaves.
📡 Adjust the Thermostat Settings
Your aircon may not be cooling because of incorrect thermostat settings.
How to Fix
- Ensure the mode is set to “Cool”, not “Fan” or “Dry.”
- Lower the temperature setting to 16°C – 18°C to check if it starts cooling.
- If using a battery-powered thermostat, replace old batteries.
- Reset the thermostat if issues persist.
Pro Tip: Consider using a smart thermostat for better temperature control and energy efficiency.
