Will Nest work in a Townhouse?
I live in a four-level townhouse, and our daughter's room is on the top floor. The AC unit is on the bottom floor, and the thermostat is on the second floor (a main level with our kitchen/living room). This usually means that to keep it a bearable 74-76 degrees up there overnight, we're turning the heat down on the main level to 68-69 degrees.
Can the Nest's sensors help with this, or do I just need a new AC system?
