However, the compressor required for air conditioning comes with
all heat pump furnaces, so the user doesn't need to purchase a
separate compressor.  That's the 'free' part.

 We had heat pumps installed in our 1840's house a few years ago.
Getting whole-house AC was a huge bonus to reducing our heating bill.
 I'm in New England, and it can get well below zero in winter, so
we've retained the older oil heating system (but shut down the
original four fireplaces), for when it gets too cold for the pumps.
