Aircon Unable to Dehumidify the Room? Here’s Why

If your aircon is running but the room still feels sticky or humid, something is not working as it should.

In Singapore’s climate, your aircon should naturally remove moisture while cooling. If it doesn’t, it usually means there is an underlying issue.

Common Reasons This Happens

• Thermostat set too high or wrong mode (fan mode instead of cool)

• Dirty evaporator coil reducing moisture removal

• Weak airflow due to clogged filters

• Refrigerant (gas) level too low

• Oversized unit cooling too fast without dehumidifying

Why Your Aircon Cannot Dehumidify Properly

Air conditioners remove humidity during the cooling process.

Warm air passes through the evaporator coil, moisture condenses into water, and drains out.

If the system is not cooling effectively or airflow is weak, this process becomes inefficient.

That is why your room may feel cold but still humid.

What You Should Do

• Ensure your aircon is set to cool mode, not fan mode

• Clean or replace air filters regularly

• Check if airflow feels weak

• Monitor if water is draining properly

• Call for servicing if humidity issue continues
