Understanding the Thermostat and Its Functions 24 Hour Ac Company Ac Service Near 24hr Air Conditioning Service 24 7 Ac Repair Near Me
Before diving into repair, it’s essential to understand the thermostat’s role in your AC system. The thermostat acts as the "brain" of your cooling system, constantly monitoring the ambient temperature and comparing it to your desired setting. Based on this comparison, it sends signals to the AC unit to either turn on, turn off, or adjust the fan speed.
