An air conditioner is just a heat pump running in reverse (basically). Heat pumps have efficiency >100%, while electric heating is 99.9% efficient and other forms (natural gas, wood, etc.) are significantly less efficient.
Logically, then, it is more efficient to cool a room each degree than it is to heat it.
- rayiner 7y agoNo, an air conditioner is just a heat pump pumping heat from inside the house to outside. That doesn’t change the efficiency, it’s still greater than 1. The efficiency difference is because the required temperature differential typically is much bigger for heating than cooling.
