How does central air work in an apartment building?
As the liquid refrigerant inside the evaporator coil converts to gas, heat from the indoor air is absorbed into the refrigerant, thus cooling the air as it passes over the coil. The indoor unit’s blower fan then pumps the chilled air back through the home’s ductwork out into the various living areas.

What is the difference between AC and central air?
The primary difference between forced air and central air systems, then, is that central air conditioning specifically refers to a cooling system. A central air conditioning system uses the forced-air system within your home to deliver cooled air, making use of the vents, plenums, and ducts to provide conditioned air.
Does AC use a lot of electricity?
In the typical home, air conditioning uses more electricity than anything else—16% of total electricity used. In warmer regions AC can be 60-70% of your summer electric bill, according to Austin Energy.
Does the AC use gas or electricity?
