What kind of heating system do you have. Do you have heating vents that can be opened and closed?
Lastly, do you live in a town house? When friends have lived in town house, the first floor was usually freezing and the mid floor comfortable, top floor overly warm. (Hot air does rise.)
Maybe ceiling fans would help with air circulation? (That would be an electrician.)
OP here -- we have a 3 story townhouse with a heat pump. No gas lines to our house and yes, we can open and close vents, but that doesn't help as much as I would expect. We are planning to put in ceiling plans, but I don't think that will help with the huge temperature difference that makes the basement basically unusable in the winter. We used tons of space heaters this past winter, but now with a mobile toddler, that would not be safe.
