AC Cleaning Guide: Filter Care, Deep Cleaning and Musty Odors
What is the difference between filter care and deep cleaning?
Filter cleaning is routine user care. Deep cleaning addresses accessible evaporator, blower, drainage areas and buildup according to the site. Persistent odor, weak airflow or leaks cannot be diagnosed by filter cleaning alone.
When to arrange further checks
- ✓Airflow stays weak
There is no improvement after safely cleaning the removable filter.
- ✓Musty odor returns
Indoor buildup, dampness and drainage need assessment.
- ✓Leaks or frost also occur
The issue may extend beyond cleaning.
Common questions
Can the AC run immediately after cleaning?
It depends on the cleaning method and drying condition. Follow the technician's completion checks or the manufacturer's operating instructions.
