Thereof, what causes high humidity in an air conditioned room?
Why an oversized air conditioner leads to high humidity at home. The inside AC unit has a cold evaporator coil to cool down the air. When running, the coil’s temperature is below the dew point, meaning that it’s at a temperature where water will leave the air and condense.
Does humidity affect air conditioning?
In theory, an air conditioning system should be able to remove moisture from the air. When humidity levels spike, however, most systems can’t cope. Humidity affects air conditioning negatively because it cancels out the cooling effect. When the humidity is too high, your home will feel warmer than it actually is.

Can humidity cause AC to freeze?
High moisture levels can impact your evaporator coils, causing them to freeze up. If airflow through the system is restricted, from a dirty air filter or other issue, excess humidity can build up and cause the evaporator coil to freeze.
Why is my AC not removing humidity?
Once these filters are clogged, the evaporator coil becomes vulnerable to getting dirty itself. When dirt starts accumulating on the coil, it forms a layer. This layer of dirt prevents the evaporator coil from cooling the air sufficiently. As such, it fails to suck out the humidity from the air.
