They conduct thermal energy from inside the house and release it outside the house.

Explanation: The aluminum coils (and their fins) are good thermal conductors and provide large surface area so indoor air gives up heat to the refrigerant in the evaporator coil. The refrigerant carries that heat outside, where the condenser coil conducts and convects the heat to the outdoor air. The coils do not insulate; they enable heat transfer.
