* Change the air filter regularly: Aim to change it every 1-3 months, depending on usage and the type of filter. A clean filter improves efficiency and airflow. * Keep the area around the outdoor unit clean and clear: Remove any debris like leaves, mulch, and branches that can block airflow. * Clean the condenser coils: These coils release heat and can become dirty, reducing efficiency. Turn off the power and gently clean them with a soft brush and mild detergent. * Check and clean the evaporator coils: These coils absorb heat from inside your home and can also get dirty. Turn off the power and clean them gently with a soft brush and mild detergent. Air Conditioning Maintenance Tips: * Regularly inspect and clean or replace air filters: Dirty filters restrict airflow, making your system work harder and potentially causing it to fail prematurely. * Maintain your evaporator coil: Check the coil fins once or twice a year and straighten them if bent. Clean them if they are dirty. *Clear your drain line: This line removes moisture. Inspect it every few months and clear any clogs using a pipe cleaner and vinegar.
