You’ll need to get a thermostat that is compatible with your system’s voltage requirements. Most thermostats work with low voltage systems. And the good news is, unless you have wall/floor heaters or an electric baseboard heating system, you most likely have a low voltage system because they are the most common.

Most automobile mechanics will tell you it is not a good idea to drive your car without a thermostat installed. If your thermostat becomes stuck in the closed position, though, this will cause your engine to overheat and make driving your car impossible.

Upgrading to a thermostat that automatically changes the indoor temperature setting is fairly easy, and it can trim about $180 off your annual heating and cooling costs, according to the EPA. Simple models that only control heat are sold at home centers for around $25.
