They must be cooler than the air inside the house.

Heat flows spontaneously from a warmer object to a cooler one, so for the coils to absorb heat from the indoor air their temperature must be lower than the air temperature. The other statements are not generally required: heat flow depends on temperature difference, not total thermal energy, and the coils are not insulated (they are meant to conduct heat).
