I'm in Texas, so I definitely notice AC bills more than heating. One
very nice feature of the t'stat I have (a Honeywell) is it's apparently
intelligent about short-cycling, which can damage a compressor. I don't
know to what extent it optimizes compressor use, but my bills have
definitely come down, and I attribute at least part of that to the
t'stat (although I've also patched some leaky ductwork and made other
changes that probably helped even more).
