If you suspect that your air conditioner (AC) unit is leaking water inside the wall when you turn it on or off, there are a few signs you can look out for:
Water stains or discoloration: Check the wall around the AC unit for any water stains or discoloration. If you notice wet spots, dripping, or visible water damage on the wall surface, it could indicate a water leak.
Musty or moldy smell: A persistent musty or moldy odor near the AC unit can be a sign of water leakage. When water accumulates in the wall, it creates a damp environment that promotes mold and mildew growth, resulting in an unpleasant smell.
Dripping sounds: When the AC unit is turning on or off, listen for any dripping or water-related sounds coming from inside the wall. This could be an indication of water leakage or improper drainage.
Increased humidity or moisture in the room: If you notice an increase in humidity levels or excessive moisture in the room when the AC is in operation, it may suggest that water is leaking inside the wall instead of being properly drained or collected by the unit.
If you observe any of these signs, it's essential to address the issue promptly to prevent further damage. Here are some steps you can take:
a. Contact a professional: Reach out to a qualified HVAC technician or an AC repair service to inspect and assess the situation. They can identify the source of the leak and recommend appropriate repairs.
b. Turn off the AC: In the meantime, it may be advisable to turn off the AC unit to prevent further water leakage and potential damage.
c. Protect the area: Place a container or towel beneath the AC unit to catch any water dripping from it until the issue is resolved. This can help minimize water damage to the wall and surrounding areas.
Remember, working with a professional is crucial for diagnosing and fixing AC-related issues, especially when it comes to leaks. They have the expertise to identify the problem accurately and implement the necessary repairs to ensure the proper functioning of your AC unit.
