Heating vs Cooling: Does It Take More Energy to HEAT or COOL?
It generally requires more energy to heat a home than to cool one for a number of reasons, including average temperature ranges, insulation issues, and the nature of cooling a space versus warming the air.
Heating a space requires a machine to make heat, which requires a good amount of energy. Basically, you cannot get warm air from the environment, so you must create it. Turning gas into electric energy, and then turning electric energy into heat energy (for those heating systems using electric power), is a very resource-heavy process. Cooling a space, on the other hand, requires a machine to move the heat, by taking it out of the house, and replacing it with cool air in an efficient cycle.
Moreover, within the HVAC industry, air-conditioning systems have also made greater strides in terms of energy efficiency than heating systems, due to the basic nature of their function.
