How long does a car thermostat last?

Unless an engine overheats or fails to reach normal operating temperature after being driven for several miles, the thermostat that regulates the flow of coolant is probably working properly. Thermostats generally last for years — even for the lifetime of a vehicle — so why bother changing it?

Can thermostat wires shock you?

You take a personal risk touching any wire, you can die from electrical shock, you have no way of knowing what is on that circuit. As said above, thermostats can be a 12 or 24V circuit, or a 120/240V one, that would zap you quite nicely.

Is it easy to change a thermostat?

Is RC the same as C wire?

Though it is a common notion, it may be incorrect to state that the C-wire powers the thermostat. Typically, the wires that give the power supply (usually termed as the 'hot' wires) are marked Rc (for cooling) and Rh (for heating). They give a 24-volt power supply from the HVAC system's control panel.

Is the C wire a ground?

The C wire is the common wire ground wire. You already have 24v ac going to the red wire. If you have an extra wire connect it to the C at the thermostat and ground it at the transformer box in the AC unit.

How many wires do I need for a thermostat?

In the most basic system, this functionality is provided by use of a fan center relay, and the low voltage wiring to the thermostat now will require a minimum of three wires (for heat only units) and four wires (for heat / cool / fan) for control. This additional terminal is labeled 'G' in the thermostat.
