-An air conditioning system has two coils, condenser coils and evaporator coils usually made of copper tubes with aluminum fins. The evaporator coil, or indoor coil, is often described as the “cold” coil because it provides indoor cooling. The coil works by absorbing heat from the indoor air that is blown over by the air handler’s fan. The condenser coil or outdoor coil is the “warm” coil as it rejects the heat as a fan blows outside air over the surface.
