A unit can be a measure of length. It is one-dimensional. A squared unit can be a measure of area. It is two-dimensional. A cubic unit can be a measure of volume. It is three-dimensional.
This depends on what unit you are using to measure in. However, area will always be measure in (unit)^2.

This question is a little vague, but I'll make by best attempt. I am assuming you mean a whole-house HVAC unit, and that you are concerned with a possible power surge so you want to shut the unit off at the thermostat. If this is correct, you need to know that the thermostat doesn't control the HVAC unit the way a switch controls a light fixture. As long as your HVAC breaker is on, you will have AC power at the HVAC unit. This usually includes at least a condenser unit outside and a blower either outside or inside. All the thermostat does is tell the HVAC components when to use the power applied and when to do nothing. The power does not flow through the thermostat to the HVAC like power through a switch to a light. Think of it this way: 'Off' on the thermostat doesn't mean power off. It means 'power available, but unit not running'. So, if you want to protect your HVAC from the potential of a power surge you will have to shut off the circuit breaker(s) feeding the HVAC components, not the thermostat.
