What does it mean when your thermostat clicks?
When your thermostat clicks, you hear the electrical contacts within the thermostat completing a circuit. A contact allows a low-voltage electrical current to travel between your heating and/or A/C system and the thermostat. As the current is traveling back to the system, your air handler or boiler gets the OK to start running.
