How do you know if something is wrong with your thermostat?
HVAC system won’t turn on: The most obvious sign of a bad thermostat is that the HVAC system in your building won’t turn on or respond to the thermostat. If you make changes at the thermostat and get no response whatsoever from your furnace, air conditioner, or heat pump, it could mean the thermostat is bad.
What can cause a new thermostat to go bad?
