Understanding the Thermostat’s Role Emergency Heating Repair Near Me Ac Repair Man Near Me Commercial Air Conditioning Service Near Me
Before diving into troubleshooting, it’s important to understand the role of the thermostat. The thermostat is the brain of your AC system. It constantly monitors the temperature in your home and signals the AC unit to turn on or off to maintain the desired temperature. It works by comparing the current room temperature to the set temperature. If the room is too warm, the thermostat sends a signal to the AC unit to start cooling. Once the desired temperature is reached, the thermostat signals the unit to shut off. 24 Hour Emergency Heating Service 24 7 Hvac Service Heating And Air Conditioning Service Near Me
