If your air conditioner is running but the space stays warm, note when the problem started and whether the airflow has changed. Those details help a technician understand what to check.
Check the thermostat mode and the condition of the air filter according to the equipment instructions. Avoid opening electrical panels or attempting refrigerant work.
If you notice ice, repeated shutdowns, or unusual sounds, arrange a system assessment. Tell Ziggy what you observed so the next step can be discussed.
