You can probably think of two to eight ways to carve up your home into cooling/heating areas. (These are called zones in AC lingo.) Zones go way beyond just upstairs/downstairs. So, when you’re sleeping, no cooling the kitchen. And when you’re cooking or watching TV, no cooling or heating the bedrooms or even the dining room. Saving energy (and money) has never been so logical.
And you’ll just have to find another way to get steps on your Fitbit, because every zone has its own thermostat. When you’re in a zone, you control the temperature right there.
Be comfortable. Save money. Life is good.
