If your thermostat starts to break down it could cause huge issues for your home. If your thermostats aren’t calibrated correctly then it could lead to your home being too warm because the thermostat is detecting the wrong temperature. Your air conditioner might not even come on at all if the wiring inside your thermostat isn’t working properly.
The job of your thermostat is pretty simple: it detects the temperature in its area and then determines if it needs to turn on your air conditioning system. If the temperature in your home is too high then it will activate the AC and run it until your home’s temperature cools to the desired level. At that point, it shuts off the AC and continues to monitor your home’s temperature.
