One of the most common problems with air conditioning in Torrevieja is water leaking inside the home. This issue is not only annoying but can also cause damage to walls, ceilings, or furniture if not addressed in time.
At AC Torrevieja, specialists in air conditioning installation and maintenance in Torrevieja, we explain why this happens, the most common causes, and how to prevent it.
💧 Why Does an Air Conditioner Produce Water?
First, it’s important to understand that it’s completely normal for an air conditioner to produce water.
When the unit cools the air, it also removes humidity from the environment (condensation process). This moisture turns into water, which is collected in an internal tray and drained through a pipe.
The problem arises when this process fails.
⚠ Main Reasons Why Your AC Is Leaking
1. Dirty filters or lack of maintenance
This is one of the most common causes.
When filters are dirty:
- Airflow is reduced
- The evaporator gets too cold
- Ice forms
- When it melts, it produces more water than the system can handle
👉 Result: water starts dripping inside the house.
2. Blocked drain pipe
The water produced by the system is drained through a pipe. If it gets blocked by:
- Dust
- Mold
- Dirt buildup
Water cannot flow properly and ends up leaking inside.
3. Poor installation
Incorrect installation is another frequent cause.
For example:
- The unit is not properly leveled
- The drain pipe is incorrectly positioned
- There is not enough slope for drainage
In these cases, problems often appear shortly after installation.
4. Damaged or dirty drain pan
The tray that collects water can:
- Crack
- Break
- Accumulate dirt
This causes water leaks inside the unit that become visible as dripping.
5. High humidity levels
In cities like Torrevieja, where humidity is high, the air conditioner produces more water than usual.
If the system is not properly maintained or sized, it may not be able to handle the volume.
🛠 How to Prevent Your Air Conditioner from Leaking
Based on our experience with air conditioning maintenance in Torrevieja, here are key tips:
✔ Clean filters regularly
At least every 2–3 weeks during summer.
✔ Schedule annual maintenance
Professional servicing prevents most issues.
✔ Check the drain pipe
Make sure it is not blocked or bent.
✔ Avoid extremely low temperatures
This can cause the evaporator to freeze.
✔ Hire professional installers
Proper installation is essential to avoid leaks.
🏖 Importance of Maintenance in Coastal Areas
In Torrevieja, factors such as:
- High humidity
- Salt in the air
- Heavy use of air conditioning
make regular maintenance even more important.
A poorly maintained system can quickly accumulate dirt and lead to problems like leaks.
