Moisture can accumulate in the AC system when it's not used regularly or when there's a leak in the system. This moisture provides an ideal environment for mold and mildew to thrive.
Clogged Cabin Air Filter
A dirty or clogged cabin air filter can reduce airflow and trap moisture inside the AC system, promoting mold and mildew growth.
3 Contaminated Air Ducts
Dust, debris, and dirt in the air ducts can provide a breeding ground for mold and bacteria, leading to musty odors.
4 Dirty Evaporat or Core
The evaporator core is responsible for cooling the air in the AC system. If it's dirty, it can trap moisture and allow mold and mildew to develop.
5 Leaky AC System
A malfunctioning or leaking AC system can allow water to collect in the air ducts or components. The presence of water promotes the growth of mold and mildew.
