If your air conditioner is dripping inside your home, this is a clear sign that something is wrong with the drainage system or the installation of the unit. Below, you will find the main causes and what to do to solve this problem quickly and safely.
1. Check the air filter
Dirty air filters hinder air circulation and can cause the coil to freeze. When the ice melts, excess water can escape through the inside of the unit.
What to do:
Turn off the unit.
Remove the filter and wash it with running water.
Let it dry thoroughly before replacing it.
Do this cleaning every 15 days.
2. Cleaning the drain pan
The drain pan collects condensed water. If it is dirty, clogged or has fungus, it can overflow.
What to do:
Remove the front cover of the unit (split model).
Locate the tray and clean it with a cloth, water and a little diluted bleach.
Check for dirt build-up at the tray outlet.
3. Check the drain
The drain tube may be blocked or poorly installed, preventing water from draining.
What to do:
Check if the tube is twisted, clogged or at an incorrect angle.
Use a jet of air (such as a pump) to unclog it.
If possible, disconnect and wash the tube with soap and water.
Make sure the tube is always pointing downwards to facilitate flow.
4. Incorrect evaporator inclination
If the inside of the air conditioner is incorrectly positioned, water may run into the room.
What to do:
Check if the unit is tilted correctly, with the back slightly lower.
If it is uneven, call a technician to adjust the wall mounting.
5. Excessive humidity in the environment
Very humid environments produce more condensation. This can overload the drainage system.
What to do:
Use the "dry" (dehumidifier) mode on your air conditioner.
Avoid opening doors and windows while the unit is on.
6. More serious problems
If after all the checks the problem persists, there may be a defect in the drain pump (in models with this function), in the coil, or another internal component.
What to do:
Turn off the unit and call a specialized technician.
Avoid continuing to use the air conditioner with dripping, as this can damage furniture, walls and the unit itself.
Conclusion
Internal drips in the air conditioner are common, but should not be ignored. Frequent cleaning, checking the drain and correct installation are the best ways to avoid this problem. When necessary, always count on a professional to ensure the proper functioning and durability of your equipment.
