Frequently Asked Questions
What happens if you don't clean the air filter in AC?
A dirty filter will restrict airflow, reduce system efficiency, increase energy costs, and could lead to equipment strain or breakdowns.
How do I know if my AC filter is working?
If air flows freely, dust is being captured, and energy bills are steady, it’s working. Reduced airflow or rising costs may signal it needs cleaning.
