    Ecobee3 is a WiFi stat that can have many wireless indoor sensors. It does have to be wired to the HVAC system. From the web, you can see the temp on the remote sensors.

    They do. But they use a lot more juice pushing air through undersized ducts and they can get really noisy. A GOOD dealer (I know, hard to find) would look at the CFM capacity of the duct system and...

    Shouldn't save much to do with the A/C. A good installer can easily change out an A coil without bothering the furnace EXCEPT in a downflow position and you can't get a short enough coil.
