The thermostat typically clicks once when it triggers the start of a heating or cooling cycle and once when it signals the end of a cycle.
How do I stop my thermostat from clicking?
An easy fix is getting additional insulation around your thermostat. This can dampen the sound from the click to keep it from disturbing you. You can also take a look at smart thermostats with integrated circuits. Since these do not use electro-mechanical relays, they run silently.

Why does my thermostat make a hissing noise?
Pneumatic thermostats often hiss when they’re telling your AC or heating system to turn on or off. Pneumatic thermostats use small bimetallic strips that “read” the temperature. So, the frequent hissing noises coming from your thermostat are simply the metallic strips adjusting the air pressure inside those tubes.
Why is my thermostat making a humming noise?
A buzzing thermostat is something you’ll want to resolve right away. If your thermostat is making a buzzing noise, there may be a loose connection in the wiring. It’s also possible the bimetallic strip or the cycling contacts on the inside of your thermostat are dirty or worn out.
