Causes Of Moisture In Car AC System
The car’s AC system is designed to cool and dehumidify the air inside the cabin, providing comfort during hot and humid weather. However, there are several factors that can lead to the presence of excess moisture in the AC system.
One common cause is low refrigerant levels. Refrigerant is responsible for absorbing heat and moisture from the air. When the refrigerant is low, it cannot effectively remove moisture, resulting in high humidity levels in the cabin.
Another cause is condensation of water vapor. As the warm air inside the car passes over the cold evaporator coil, the moisture in the air condenses into liquid form. This condensation typically drains away, but if the drain tube gets clogged or damaged, the moisture can accumulate in the AC system.
Leaks in the AC system can also introduce moisture. Coolant leaks can allow water to enter the system, adding to the already present moisture. Additionally, damaged hoses or fittings can cause refrigerant to leak out, disrupting the system’s ability to dehumidify the air.
Blockages in the air filters can prevent proper airflow, leading to condensation problems. If the filters become dirty or clogged, the air passing through may not be able to cool down and dehumidify effectively, resulting in excess moisture in the AC system.
Lastly, malfunctioning components, such as a faulty compressor, can contribute to moisture buildup. A compressor that is not functioning properly may not be able to sufficiently cool the air or remove moisture, leading to high humidity levels.

Replacing Compressor And Inspecting For Leaks
If all else fails in removing moisture from the car’s AC system, replacing the compressor may be necessary. The compressor is responsible for pressurizing the refrigerant and circulating it through the AC system.
A malfunctioning compressor cannot effectively remove moisture or cool the air, which can lead to high humidity levels. Replacing the compressor can eliminate moisture problems and improve the overall performance and efficiency of the AC system.
Inspect the AC system for coolant leaks as they can introduce moisture into the system and worsen the moisture problem. Check all the hoses, fittings, and connections for signs of leaking or damage.
If leaks are detected, promptly address them. Depending on their location and severity, they may need to be repaired or replaced. Use a detector specifically designed to find coolant leaks to pinpoint the source of the problem.
Another effective solution for fixing coolant leaks is to use a sealant designed for AC systems. This sealant is typically added to the AC system and forms a seal around the leaking area, preventing further leaks and moisture ingress.
Solvent And Moisture Absorber Methods
In addition to the aforementioned methods, there are other ways to remove moisture from a car’s AC system.
- Using solvents specifically designed for AC systems can help eliminate moisture and improve the system’s performance.
