They must be cooler than the air inside the house.

Heat flows spontaneously from higher temperature to lower temperature, so for the coils to absorb heat from the indoor air their temperature must be lower than the air. (Total thermal energy depends on mass and specific heat and is irrelevant here; being insulated would prevent heat flow, not help it.)
