Someone told me that that actually would cost more in the end, b/c
the furnace has to work harder to get the temp up from 60 to 70
everyday, than it would to just keep it at a constant 65.

Furnaces don't "work harder", they just run longer.

Some programmable thermostats have a clock which keeps track of how
long they've been running the A/C or furnace. If yours has that, try
a couple of different schemes and see which one has the least amount
of furnace on time.

If not, and you're reasonably handy, you might be able to cobble
together something yourself.
