There’s no doubt about it: Most homeowners have a gripe about the temperature in their homes. Ask whether or not they’re comfortable, and they’ll likely point to one or two rooms and say that those spaces are too hot in the summer and/or too cold in the winter.
Depending on the size and configuration of the house and the preferences of the occupants themselves, it may just simply be too much to ask one thermostat to keep every room comfortable for every person in the house.
