How does cold air work?
Cold refrigerant runs through an evaporator coil of your system, pulling along warm indoor air over the top of the coil. So, moisture in the air condenses and then drips off the coil and into a pan. When you’re running a central air conditioning system, there is plenty of this condensation, so water is consistently dripping into the pan. The system then directs this water outside.
