Step-by-step troubleshooting

1. Check Thermostat Settings
   Do: Ensure the thermostat is set to 'Cool' and the temperature is lower than the room temperature.
   Observe: Thermostat may display an error code or not respond.
   Means: Thermostat malfunction or incorrect settings.
   Next: Replace batteries or recalibrate the thermostat.
2. Inspect Air Filter
   Do: Remove and examine the air filter for dirt or blockage.
   Observe: Filter is dirty or clogged.
   Means: Restricted airflow causing reduced cooling.
   Next: Clean or replace the air filter.
3. Check Power Supply
   Do: Verify the circuit breaker for the AC is on and the outdoor unit has power.
   Observe: Breaker is tripped or outlet has no power.
   Means: Electrical issue preventing operation.
   Next: Reset the breaker or check wiring connections.
4. Clean Condenser Coils
   Do: Turn off power and clean debris from the outdoor unit's condenser coils using a brush or vacuum.
   Observe: Coils are dirty or obstructed.
   Means: Reduced heat exchange efficiency.

   Means: Leak in the refrigerant system.
   Next: Contact a licensed HVAC technician.
6. Check Fan Motor
   Do: Listen for grinding or squealing noises from the outdoor unit.

   Next: Replace the fan motor if necessary.
7. Inspect Ductwork
