The answer to 'how to maintain HVAC system' is to perform regular maintenance and cleaning. This includes changing air filters every 1-3 months, cleaning the outdoor condenser unit annually, and scheduling professional tune-ups and inspections every 1-2 years. Proper maintenance helps your HVAC system run efficiently, extends its lifespan, and ensures safe operation.
To maintain your HVAC system, start by checking and replacing the air filters regularly. Dirty filters restrict airflow and make the system work harder, increasing energy use and wear on components. Next, clear any debris or vegetation around the outdoor condenser unit and use a garden hose to gently spray the coils and fins to remove dirt and dust buildup. Finally, have a qualified HVAC technician perform a comprehensive inspection and tune-up every 12-24 months to check refrigerant levels, clean components, and identify any issues before they become major problems.
