Default Strange noise coming from furnace after AC has shut off. Normal?

It might be the condensate pump.

Are condensate pumps the norm? Never seen one before in a few systems I
have looked at.

Mine doesn't have one either - just gravity flow from the pan to the
drain. However if the drain was higher than the pan I would see a need
for one.
