The main reasons an air conditioner (AC) may not be blowing cold air include:
- Incorrect thermostat settings: The fan might be set to "ON" instead of "AUTO," causing the blower to run without cooling the air.
- Dirty or clogged air filters: Restricted airflow reduces the AC's ability to cool.
- Refrigerant issues: Low refrigerant or leaks prevent proper cooling.
- Frozen evaporator coils: Prevent heat absorption, leading to warm air output.
- Dirty coils or condenser unit: Dust and debris on coils reduce cooling efficiency.
- Blocked vents or registers: Obstructions hinder airflow distribution.
- Faulty thermostat or electrical issues: Malfunctioning controls or power problems can stop cooling.
Checking and correcting these factors or contacting a professional for refrigerant problems or frozen coils is recommended to restore cold air blowing from the AC.
