 let it rest during the day when I'm not home, and then I crank it hard when I get home. Yeah, well, it depends really what type of system you have. There's all different systems now versus the old systems where we had a single-stage blower and that was it. Now we've got five-stage blowers, variable-speed blowers. We've got all kinds of things. So there's a bigger savings on heating by setting and moving temperatures than there is on air conditioning.
