My HVAC system keeps turning off on its own, what gives?

If the system turns off, it might be because of a faulty thermostat or a lack of airflow. The thermostat might be the culprit if it’s not calibrated correctly or if there’s a power outage. If the airflow is restricted, it will cause the system to overheat.
