Your car’s air conditioning system is essential not just for comfort but also for safety. A properly functioning A/C system keeps your car interior cool, maintains visibility by defogging windows, and helps filter pollutants. Over time, neglecting your air conditioning system can lead to poor performance, unpleasant odours, and even costly repairs.
To avoid such problems, here are eight essential tips to keep your car’s A/C in top condition — with a special focus on cooling coil maintenance using the advanced TUNAP aircowell® car aircon cleaning system.
-
Keep the Cabin Air Filter Clean
The cabin air filter traps dust, pollen, and other airborne particles, improving the quality of the air inside your car. A clogged or dirty filter can strain the A/C system, reduce airflow, and cause musty smells. It’s generally recommended to replace the cabin air filter every 20,000km or once a year — more frequently if you drive in dusty or polluted environments.
It is also important to clean the pollen filter box with TUNAP 996 or 998 prior to each filter replacement. This will ensure a clean and hygienic pollen filter box for the filter to work well.
-
Use the Recirculation Mode
When temperatures soar, switching to the recirculation mode helps your A/C cool the cabin more efficiently. This setting pulls air from inside the vehicle rather than from outside, reducing the workload on the compressor and achieving desired temperatures more quickly while also saving fuel.
- Check Refrigerant Levels
Low refrigerant (commonly referred to as Freon or R-134a/R-1234yf) can significantly reduce cooling performance. If your car isn’t cooling properly, have the refrigerant checked by a professional. Avoid DIY refilling unless you’re experienced, as overfilling can damage the system.
- Inspect the Drive Belt
The A/C compressor is powered by a serpentine or drive belt. Over time, belts can crack, stretch, or wear out, causing the A/C system to underperform or fail. Regular inspection of the drive belt for signs of wear or damage and timely replacement is critical to ensuring a functional air conditioning system.
- Keep the Condenser Clean
Located at the front of the vehicle, the condenser dissipates heat from the refrigerant. Dirt, leaves, and debris can clog the condenser fins, restricting airflow and reducing cooling efficiency. Periodically cleaning the condenser with compressed air or a gentle hose spray can go a long way in maintaining system performance.
- Watch for Unusual Smells or Noises
A foul smell coming from the vents could indicate mold or bacteria buildup inside the A/C system, especially on the evaporator or cooling coil. Likewise, unusual noises like rattling or grinding could signal mechanical issues within the compressor or fan. If you notice these signs, have your A/C system inspected by a professional immediately.
- Flush the Aircon System Regularly
Regular flushing of the aircon system removes moisture and contaminant from the refrigerant and compressor oil. The machine will top up the refrigerant and compressor oil to the required level if it is low. This ensures a smooth operation of the aircon system.
It is recommended to flush the aircon system every 2 to 3 years or when major components of the aircon system is changed.
- Clean the Cooling Coil with TUNAP aircowell® Car Aircon Cleaning System
The cooling coil (or evaporator coil) is where moisture condenses and cools the air before it enters your cabin. Unfortunately, it’s also a prime area for bacterial and fungal growth due to the constant moisture. Dirty cooling coils can lead to poor air quality, musty smells, and reduced cooling efficiency.
This is where the TUNAP aircowell® Car Aircon Cleaning System comes in. It’s a professional-grade solution specifically designed to clean the cooling coil without disassembly or harmful chemicals. The TUNAP system uses a patented pressure gun and probe to reach deep into the evaporator housing, delivering a non-corrosive cleaning agent that removes biofilm, bacteria, and mold — all without dismantling the dashboard.
Unlike traditional “spray” solutions that only mask odors or clean the vents, TUNAP aircowell® targets the root of the problem: the evaporator surface and drainage system. This treatment is not only more effective but also environmentally responsible, dermatologically safe, and recommended by leading car manufacturers. The very same system is also widely used by major car manufacturers such as Mercedes-Benz, Volvo, and Tesla.
Regular cooling coil cleaning using the TUNAP aircowell® system ensures:
- Fresher air inside the cabin
- Long-term protection against microbial growth
- Improved cooling performance
- A healthier environment for you and your passengers
TUNAP aircowell® aircon cleaning system has been verified by the following agencies:
1) Cleaning method certified as most effective by VDI Germany
2) ECARF 5-star certification for allergy friendliness
3) BIFA independent certification for accuracy of air quality sensor to measure cabin air quality
4) TUV certified
5) Research and Testing was completed with Fraunhofer Institute
Experts recommend this treatment once a year to ensure optimal performance and hygiene.
Final Thoughts
Maintaining your car’s air conditioning system doesn’t have to be complicated — but it does require attention. By following these eight tips, from regular use and cleaning to advanced care like the TUNAP aircowell® car aircon cleaning system, you can keep your A/C system performing like new, enhance driving comfort, and avoid expensive repairs in the future.
Stay cool and breathe easy — your car (and your lungs) will thank you.
