While running the fan on your air conditioner can provide some relief on a hot and muggy day, it won’t do much to reduce the humidity in your home. In fact, the primary function of the fan is simply to circulate the air already in the room, rather than to remove any moisture from it.
To actually decrease the humidity levels in your home, you need to use your air conditioner’s cooling function. This process involves removing heat and moisture from the air, then expelling the cooled and dehumidified air back into the room. So if you’re looking to beat the heat and humidity, make sure to turn on the cooling function on your air conditioner instead of relying solely on the fan.
