The constant running of your AC unit will reduce pressure in the evaporator, or cooling coil until it freezes over, according to Cool Today. This is why in some cases, this constant running can be dangerous. The freezing of the coil can cause liquid refrigerant to flood back into the unit’s compressor and damage it.
How long should it take to cool a house from 78 to 75?
