1. Check the air conditioning system’s overall condition, including filters, coils, and ducts for wear, leakage, or damage. 2. Remove dust and dirt from filters, coils, and drains to maintain performance. 3. Ensure correct refrigerant levels to avoid cooling issues and fix any leaks. 4. Verify that the thermostat is accurate and functioning smoothly. 4. Lubricate motors and moving parts to reduce friction and ensure smooth operation. 5. Look for blockages or leaks in ducts that could impede airflow. 6. Test the system to ensure effective cooling and proper response to thermostat settings.
