A programmable thermostat can help, and not only because it can be used
to set back temperatures during part of the day -- some (many?) of them
also have sufficient "smarts" to keep the system from short-cycling,
which is wasteful and potentially harmful to your system.



I know that's a problem for compressors. How would it effect gas or
electric heat?

I had AC in mind. I doubt it would help with heat, although starting
and stopping the furnace fan probably uses a fair amount of electricity.
