      Thermostats in most residential settings are just a series of on/off switches. All it does is complete the 0.5v circuit from your HVAC control board that tells it which parts to activate.

      The only way for a thermostat to cause any extra wear and tear on the AC unit is if it was rapidly turning on/off. However most thermostats, including Nest, have a maintenance band of +/- a couple of degrees, to prevent that sort of rapid cycling.

      If @stranger@lemmy.world is going through AC units that fast, they likely have a more serious electrical problem in their home.
