Installing a programmable thermostat was the best $50 I ever spent on my house.

This simple device has consistently lowered my heating and cooling bills every month since installation.

That "consistently lowered" part is the real trick. The thermostat itself doesn't save a dime if you just program it for your existing schedule. The savings only come from actually reducing runtime, like letting the house drift while you're at work. Most people I know just end up overriding the program constantly.

I programmed mine for a 10-degree swing when out and learned to live with the rebound.

Wait, you let it swing a full ten degrees? That's downright heroic (or maybe masochistic). I tried a five-degree setback once and the recovery period felt like the system was screaming for mercy, chewing through any theoretical savings. A ten-degree gap means your unit must run forever to catch up, probably at peak demand rates too. I'm genuinely shocked your system even handles that without short-cycling itself into an early grave.
