Finding water on your passenger floorboard after running the AC can be frustrating — and it’s a sign something isn’t working as it should. Many drivers come to us asking, “Why is my car AC leaking water inside in Marble Falls?”, and at Marble Falls Auto Center, we know the most common causes and how to fix them before they damage your interior.
Common Reasons Why My Car AC Is Leaking Water Inside in Marble Falls
1. Clogged AC Drain TubeYour AC system naturally produces condensation, which drains outside through a small tube. If that tube gets clogged with dirt or debris, the water backs up and ends up on your floor.
2. Damaged or Disconnected Drain HoseIf the drain hose becomes loose or cracked, the water will leak inside the cabin instead of draining outside.
3. Faulty Evaporator CoreWhen the evaporator develops damage or corrosion, it can lead to excess moisture and leaks inside your car.
4. Excess CondensationIn hot, humid Texas summers, AC systems sometimes generate more condensation than usual, which can overwhelm a weak or partially blocked drain system.
5. Cabin Air Filter IssuesA dirty or clogged cabin air filter can reduce airflow, which may cause ice buildup on the evaporator. When the ice melts, it can drip inside the vehicle.
How to Fix an AC Leak Inside the Car
At Marble Falls Auto Center, we perform a complete AC inspection, checking the drain tube, hose connections, evaporator, and cabin filter. Depending on the cause, the fix might be as simple as cleaning the drain line or as involved as replacing an evaporator core.
Why You Shouldn’t Ignore AC Water Leaks
Even small amounts of water can damage carpets, cause mold, and create unpleasant odors in your vehicle. The sooner you address the leak, the less chance you have of costly interior repairs.
