Prevent AC breakdowns by scheduling regular maintenance, including annual professional inspections and tune-ups. Change or clean air filters every 1-3 months to ensure proper airflow. Keep the condenser and evaporator coils clean and free of debris. Check and clean the condensate drain line periodically to prevent clogs. Ensure that the thermostat is working correctly and set to an appropriate temperature. Additionally, inspect and seal any ductwork leaks to maintain efficiency and reduce strain on the system.
