If your window AC is leaking water from the front side, it could be due to several reasons. Here are some common causes of water leakage from a window air conditioner:
- Clogged or Dirty Air Filter: A dirty or clogged air filter can restrict airflow, causing the evaporator coil to freeze. When the frozen coil melts, it can lead to excess water dripping from the front of the unit.
Solution: Check and clean or replace the air filter regularly, usually every 1-2 months during periods of use.
- Blocked or Clogged Drainage Hole: Window AC units have a drainage hole at the back or bottom to allow water to escape. If this drainage hole becomes blocked or clogged with debris, the water can overflow and leak from the front of the unit.
Solution: Locate the drainage hole and ensure it is clear of any obstructions. You can use a paperclip or a small brush to gently clear the blockage.
- Incorrect Installation: If the AC unit is not properly installed with a slight tilt toward the outside, water may not drain correctly, causing it to leak from the front.
Solution: Check the installation of the AC unit and make sure it is angled slightly downward toward the outside to allow proper drainage.
- Excessive Humidity: In very humid conditions, window AC units may produce more condensation than usual, leading to increased water leakage.
Solution: Consider using a dehumidifier in the room alongside the AC unit to reduce indoor humidity levels.
- Damaged or Clogged Drain Pan: The drain pan inside the AC unit collects condensed water. If the drain pan is damaged or clogged, it may cause water to leak from the front of the unit.
Solution: Inspect the drain pan for any damage or clogs. If necessary, replace the drain pan or clean it thoroughly.
- Low Refrigerant Levels: Low refrigerant levels can cause the evaporator coil to become too cold, leading to excessive condensation and water leakage.
Solution: This issue requires professional attention from an HVAC technician. If you suspect low refrigerant levels, contact a qualified professional to inspect and recharge the refrigerant as needed.
If the issue persists despite trying these solutions, it's best to have a professional HVAC technician inspect and diagnose the problem. They will be able to identify the root cause of the water leakage and perform any necessary repairs or adjustments to restore the AC unit's proper functioning.
