4. Is Water Leaking From My Car AC Normal?

Is it normal for my car AC to leak water? Understanding the difference between condensation and a refrigerant leak.

It’s normal for a car’s AC system to produce water or condensation, which you’ll see dripping from under the vehicle when the AC has been running. This is a normal result of the AC system’s operation and is not a cause for concern. According to a study by the Vehicle Thermal Management Systems Conference (VTMS) on December 1, 2023, condensation occurs because the evaporator core cools down significantly, causing moisture in the air to condense on its surface. This water then drips out of the system through a drain tube.

However, it’s essential to distinguish between normal water drainage and an actual refrigerant leak, which is harmful and unrelated to condensation. If you notice fluid dripping under your car that has an oily or colored appearance, it’s likely that you have a problem which may or may not be a refrigerant leak. In cases like these, it’s advisable to have your car’s AC system inspected by a professional technician to rule out any issues and ensure the ventilation system is functioning correctly. CARDIAGTECH.NET offers diagnostic services to help you determine the nature of any leaks and ensure your AC system is functioning correctly.
