Why Is Your AC Not Cooling?

Your AC is running but the room isn't getting cold. The air coming from vents is warm or barely cool. The thermostat shows a temperature far higher than your setting.

This is one of the most common AC complaints in Dubai, and also one of the most frustrating when outdoor temperatures exceed 45°C.

Common Causes of AC Not Cooling

Low Refrigerant

The most common cause. Your system may have a slow leak that's depleted the refrigerant charge over time. Without adequate refrigerant, the system cannot absorb and transfer heat effectively.

Dirty Filters

Dirty filters restrict airflow, reducing cooling capacity. In Dubai's dusty environment, filters clog quickly and need regular attention.

Dirty Coils

Dirty evaporator or condenser coils reduce heat transfer efficiency, leaving your system working hard without achieving results.

Compressor Problems

The heart of your system isn't functioning properly. This is the most serious diagnosis and requires professional attention.

Thermostat Issues

Your system may not be receiving correct instructions, or the sensor isn't reading temperature accurately.

Airflow Restrictions

Blocked vents, duct problems, or fan issues prevent cool air from reaching your space effectively.

Before calling a technician, check these simple things that might solve your problem without a service call:

Thermostat Settings

Ensure it's set to cool mode and the temperature is set below room temperature.
