The answer to 'how to clean inspection' is to regularly inspect and clean the HVAC system's air filters, coils, and other components. This helps maintain efficiency, improve indoor air quality, and extend the system's lifespan.
For air filters, it's recommended to check them monthly and clean or replace them as needed, typically every 1-3 months. Coils should be cleaned annually by a professional HVAC technician. Other components like the blower, ductwork, and condensate drain should also be inspected and cleaned periodically to ensure proper airflow and prevent issues.
