There are a few signs that can indicate if a window air conditioner is leaking water inside the house:
Visible water accumulation: Check around the base or bottom of the air conditioner unit and the surrounding area. If you notice water pooling or dripping, it is a clear indication of a water leak.
Water stains or damage: Look for water stains or discoloration on the wall, floor, or nearby furniture located below the air conditioner. These stains can indicate that water has been leaking and causing damage.
Dampness or moisture: If you notice excessive moisture or dampness around the air conditioner or nearby surfaces, it could be a sign of water leakage. Pay attention to any areas where moisture seems to be accumulating or causing dampness.
Musty or moldy odor: A persistent musty or moldy smell near the air conditioner can suggest water leakage. Excess moisture can create an environment conducive to mold growth, resulting in unpleasant odors.
Water dripping from the front panel: Sometimes, water leakage can occur from the front panel of the air conditioner. If you see water dripping or running down from the front of the unit, it may indicate an internal issue with the drainage system.
If you suspect that your window air conditioner is leaking water inside the house, it is important to address the issue promptly to prevent further damage and potential health concerns. You may consider contacting a professional HVAC technician to inspect the unit, identify the source of the leakage, and perform any necessary repairs or maintenance.
