What does water leakage mean?

Noticed any damp spots in your car’s interior lately? Your AC system is an important part of your vehicle and ensures you stay cool during the warmer months. Leakage in the cabin is a sign that something might be wrong and it should be checked out as soon as possible.

Condensation resulting in water puddles under your car is perfectly normal, but sometimes this water can escape into the car’s interior. This signifies a bigger problem. It is also possible that coolant may have escaped into the cabin, but this is a separate issue and is usually picked up on more quickly. If you haven’t had any sloppy passengers or slobbery dogs in your car recently, chances are your air conditioning system might need some TLC.

Moisture inside the car can be incredibly dangerous. As the engine and interior of the vehicle warm up, water can lead to increased fogging in the interior while the windows are up. This, in turn, can cause dangers for drivers and pedestrians around your vehicle. If your windows are too foggy to see, and you can’t open your windows due to inclement weather, you are effectively driving blind.

In the end, it’s best to have any excess interior or exterior moisture addressed as a priority. You owe it to yourself and your family.

Natrad technicians across Australia can diagnose any air conditioning problems. If something with your AC doesn’t seem quite right, nip into your local store today.

So, you’ve noticed some dampness inside your car. Now what? Well, condensation pooling underneath the car is not a sign of trouble (unless it’s a lot)… When it makes its way to the inside of the car, then something more sinister is probably going on.

Normal condensation comes from the evaporator, so it is likely the problem originates from this part of the system. Water inside the car can be problematic as it can cause mould and mildew which is harmful to breathe in. If you have noticed this happening, notify a Natrad workshop asap!

Potential causes
Some reasons why water is leaking to the inside of the car instead of the outside include the following;

  • Clogged drainage hole: when blocked by dirt or debris, the condensation drainage can back up. Once it overflows, this liquid can find it’s way into the AC vents and hence into the car’s interior.
  • Failing seals: if the plastic or rubber seals in your system dry out or fail, water can seep out of the system and into your vehicle cabin.
  • Improperly attached ventilation system: improper attachment means that the drainage of condensation is not happening as it should. Instead of draining under the car, it can escape through the AC vents.
  • Refrigerant leak: leaking refrigerant means there is not the right amount of pressure in the system. It can then build, causing the condensate drain pan to overflow.

What happens if my AC is leaking?

Now you know why it’s leaking, it’s time to figure out your next step. Leaking into the cabin is not only problematic thanks to the harmful mould it can cause, but also for the AC system itself. Depending on the cause of the leak, the system may be in danger of failure.

For example, a refrigerant leak could mean that the system is not running optimally (making it work harder) and does not stay lubricated. Over time this can do damage to other AC system components and pose more critical and expensive problems to your vehicle’s cooling system.

Some other AC symptoms to watch out for are:

  • Strange/sweet aroma
  • Weak airflow or warm air
  • Inconsistent air temperature
  • Compressor won’t activate
  • Foggy windows

If you’ve noticed any of the problems mentioned in this article, it’s a good idea to get the system checked by a professional. AC systems generally last a long time as they are a closed loop, but sometimes things can fail.
