2. How to Maintain Car AC System – Expert Guide by Crystal Valet Introduction Your car’s air conditioning system is more than a comfort feature—it’s essential for a smooth and enjoyable driving experience. At Crystal Valet, we believe that just like regular car washing and car detailing services, your car AC also deserves proper care to ensure long-lasting performance. A well-maintained AC system not only keeps you cool in summer but also improves air quality inside the vehicle. In this guide, we will explain how to maintain car AC system step by step, with expert advice from Crystal Valet. Why You Should Maintain Your Car AC System At Crystal Valet, we see many vehicles come in for detailing and servicing where the AC system has been neglected. Regular maintenance of your car AC system is important because: It keeps the cabin cool and comfortable. It ensures cleaner, healthier air circulation. It saves money by preventing costly repairs. It extends the lifespan of vital components like the compressor and condenser. That’s why our experts always recommend making AC maintenance part of your regular car care routine, just like car washing and detailing. 1

3. 1. Run Your Car AC Regularly One of the easiest tips on how to maintain car AC system is to run it at least once a week. Even in winter, switching on your AC for 10–15 minutes keeps the compressor lubricated, maintains proper gas pressure, and prevents seals from drying out. At Crystal Valet, we always advise customers to follow this simple step to avoid expensive repairs later. 2. Clean or Replace the Cabin Air Filter A clogged cabin filter restricts airflow and reduces cooling. Our team at Crystal Valet often finds dirty filters when cars come in for detailing. To maintain efficiency: Check your car’s manual for the filter’s location. Clean it every 6 months and replace it annually. A clean filter ensures smooth airflow and prevents bad odors. During our car detailing services, we can inspect and clean your filter for maximum performance. 3. Monitor Refrigerant Levels Without the right amount of refrigerant, your car AC won’t cool effectively. Signs of low refrigerant include weak cooling, hissing noises, or frost on the compressor. At Crystal Valet, we recommend checking refrigerant levels during routine servicing. Our professional technicians can recharge your AC system safely and efficiently. 4. Inspect and Clean the Condenser The condenser, located at the front of the car, is often exposed to dirt and debris. If it’s blocked, cooling performance drops. As part of Crystal Valet’s detailing service, we inspect the condenser and radiator to ensure smooth airflow and optimal AC performance. 2

4. 5. Prevent Moisture Build-up Moisture inside the AC can cause bacteria and mold growth, leading to unpleasant odors. To prevent this, run your AC on defrost mode for 5–10 minutes once a week. At Crystal Valet, we also offer interior cleaning services to remove any mold or bacterial growth affecting your AC system. 6. Pay Attention to Noises and Smells Strange noises may indicate compressor issues, while bad odors often signal mold in the evaporator. Instead of ignoring the signs, visit Crystal Valet for a full check-up. Our team can disinfect ducts, clean evaporators, and restore fresh airflow to your car. 7. Maintain the Drive Belt and Compressor The drive belt is crucial for the compressor’s function. Worn-out belts cause the AC to underperform. At Crystal Valet, our experts check belts and replace them when necessary during detailing and servicing, ensuring your AC runs smoothly. 8. Get Professional AC Servicing While you can handle basic cleaning and maintenance, professional servicing is essential. At Crystal Valet, we provide comprehensive AC servicing, including refrigerant checks, leak detection, evaporator cleaning, and airflow testing. Regular servicing once every 12–18 months keeps your AC in perfect shape. 9. Don’t Overload the AC System Turning your AC to full blast immediately on a hot day strains the system. Instead, roll down windows first to release hot air, then switch on the AC at a moderate level. At Crystal Valet, our experts always recommend this technique to extend AC life and improve efficiency. 3

5. 10. Protect Your Car from Excess Heat Minimizing heat inside your car reduces AC workload. Park in shaded areas, use windshield sunshades, or tint your windows (where allowed). During detailing at Crystal Valet, we also apply protective treatments that help reduce interior heat. Conclusion Learning how to maintain car AC system is essential for every car owner. From running your AC regularly and cleaning air filters to professional servicing, these small steps make a big difference. At Crystal Valet, we provide expert car washing service, car detailing service, and professional AC care to ensure your vehicle stays in top condition. By trusting Crystal Valet, you not only get a spotless car but also a perfectly functioning AC system that keeps you cool, comfortable, and safe on the road. 4
