“Air-conditioning systems run most efficiently when they’re running at full speed,” she explains. So while your unit might make more noise initially cooling a space down from 80 to 75 degrees, running all day at a less powerful speed requires more energy overall.

Is it better for AC to run constantly?

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.
