To troubleshoot your AC if it isn't cooling, follow these steps:
Check the Thermostat: Ensure it's set to "cool" and the temperature is below the current room temperature.
Inspect the Air Filter: Replace if dirty to ensure proper airflow.
Examine the Circuit Breaker: Reset if tripped.
Inspect the Outdoor Unit: Clear any debris around it.
Check for Ice: If present on coils, turn off the AC and let it thaw.
If these steps don't resolve the issue, contact a professional HVAC technician for further diagnosis.
