Through the ductwork of your home, a central air conditioner pulls warm air in through your furnace or air handler. Cooling occurs when the air is blown across the evaporator coil, located generally above your furnace. Then, through the coil, heat is absorbed by refrigerant which is then pumped to the air conditioner’s condensor located outside of the home. By releasing this heat into the outside air, the condenser cools the refrigerant, which is then pumped inside the home to begin the cycle again.
