Experiencing water leaking inside your car whenever the air conditioning (AC) is on can be frustrating and concerning. Many drivers in Dubai notice this issue during the hot months when the AC is constantly in use. But what causes an AC to leak inside the car, and how can it be fixed?
In this blog, we’ll break down the common causes, warning signs, and effective solutions to help you understand and address the issue. If you’re facing this problem, finding reliable car AC repair in Dubai is essential to prevent long-term damage to your vehicle’s interior.
Why Is Water Leaking Inside My Car From the AC?
First, it’s important to understand that a small amount of water dripping outside the car is normal—it’s a result of condensation from the AC system. However, if water starts leaking into the passenger cabin, that signals a problem.
Common Causes of AC Leaking Inside the Car
1. Clogged or Disconnected Drain Line
Your car’s AC system creates condensation, which should drain outside via the evaporator drain line. If this line is clogged with dirt, debris, or mold, or has become disconnected, the water will back up and leak into the car’s interior, often on the passenger side floor.
2. Damaged or Dislodged Evaporator Core
If the evaporator coil is damaged, water can escape and seep into the dashboard or footwell. This is a more serious issue and usually requires professional inspection and repair.
3. Dirty Cabin Air Filter
A blocked or extremely dirty cabin air filter can restrict airflow, causing excess moisture to form on the evaporator coils. This can eventually lead to water leaks inside the car.
4. Low Refrigerant Levels
Low refrigerant can cause the evaporator coil to freeze. When it melts, it can produce excess water that overwhelms the drainage system and leaks inside the car.
5. Faulty AC Seals or Gaskets
Worn-out gaskets or seals around the AC system components can allow moisture to escape into areas it shouldn’t, leading to wet carpets or damp dashboards.
How to Fix an AC Leak Inside Your Car
1. Unclog the AC Drain Line
This is the most common fix. A technician can blow compressed air through the drain line to remove blockages. In some cases, the hose may need to be reconnected or replaced entirely.
2. Replace or Clean the Cabin Air Filter
Changing the cabin air filter regularly is a simple way to maintain airflow and prevent moisture buildup.
3. Inspect AC Components
A thorough inspection of the evaporator coil, AC seals, and hoses can reveal damage that might be causing the leak. Professional diagnostics are recommended.
4. Recharge the Refrigerant
If refrigerant levels are low, a proper recharge can restore performance and stop freezing/melting cycles that cause leaking.
Don’t Ignore the Signs
If left unresolved, an AC leaking inside your car can lead to:
- Mold and mildew buildup
- Unpleasant odors
- Electrical damage beneath carpets or in the dashboard
- Reduced resale value of your vehicle
In a hot and humid climate like Dubai, where AC usage is constant, it’s crucial to act quickly.
