When a house has central AC, there is typically an
evaporator installed over the furnace. Since the tubes and
fins are shaped some what like a capital A, they are fondly
called A-coils. The term "coil" is because the early
evaporators and condensors were coils of copper tubing.

There are also W-coils, though they look more like M-coils.


You forgot the slash coils "/". *snicker*
