How does a thermostat work for air conditioning?

A tip to know how an Air Conditioner works is an AC does not make cool air. It transfers the heat from inside your home to outside your home.

When the thermostat feels the air temperature rising above your set temperature, it turns on the AC. The cooling unit then removes the heat from your house.
