    Troubleshooting Steps

    1. Check the Thermostat: Ensure it’s set to the correct temperature and mode. Replace the batteries if necessary.
    2. Inspect the Air Filters: Dirty filters restrict airflow and can cause short cycling. Replace them if necessary.
    3. Examine the Evaporator Coils: If the coils are frozen, turn off the AC and let them thaw. Check for low refrigerant or airflow issues.
    4. Listen for Unusual Sounds: If the air conditioner is making strange noises, the compressor or fan motor may be faulty.
