Cleaning your car’s air conditioning (AC) system is important for maintaining air quality and system performance. Here’s how often you should do it and what it involves:
🔁 How Often to Clean a Car Aircon System
Component
Recommended Frequency
Cabin Air Filter
Every 12,000–15,000 km or once a year
AC Vents & Ducts
Every 6–12 months or if there’s a smell
Evaporator Coil
Every 1–2 years, or if airflow is weak or smells
Full AC Service
Every 2 years, includes cleaning + gas check
🛠️ Signs Your AC Needs Cleaning
Musty or moldy smell when AC is on Reduced airflow from vents Increased allergies or sneezing in the car Unusual noises when AC is running
💡 Tips for Better Maintenance
Run your AC weekly for 10 minutes (even in winter) to keep components lubricated. Use recirculation mode sparingly – it can trap moist air, leading to mold. Avoid smoking or eating inside the car, as particles can clog filters and ducts.
