Air conditioning systems have two coils, one called the evaporator coil and a second one called the condenser coil. Coils are heat transfer devices that make heat removal possible.
The evaporator coil is located inside the house, inside the ductwork, downstream from the furnace. In most homes this would mean just above the furnace, inside the plenum (the first few feet of the main supply air duct).
The condenser coil is located outside the building but is connected to the evaporator coil inside the house by a pair of metal tubes that pass through small openings in one of the walls of the house. These metal tubes are refrigerant lines.
This is how an air conditioning (refrigeration) system works. The warm air inside a house is blown through the evaporator coil, transferring heat to the refrigerant running through the coil. This heated refrigerant is then pumped outside to the condenser coil where much of its heat load is transferred to outside air. It is a closed system, with the refrigerant fluid continually circulating, picking up heat indoors and releasing the heat outdoors.
The efficiency of the system depends on several factors but one of the most important is the cleanliness of the coils. When the evaporator coil inside the house is clean, it picks up heat efficiently from warm inside air. When the condenser coil outside the house is clean, it disperses heat efficiently into the outside air. If either of these coils becomes dirty and partially blocked by dust and debris or by layers of mold or mildew, its efficiency drops significantly. Under these conditions, the system has to run longer to achieve the required cooling effect inside the house. When it runs more, it costs more and it also tends to need repair or replacement more quickly. To avoid this costly inefficiency, manufacturers of air conditioning equipment recommend that the coils be cleaned at least annually. – http://www.safetyking.com/coil.html
