The answer to 'my system upgrade keeps shutting off' is that there could be several common causes, such as a tripped circuit breaker, a problem with the thermostat, or an issue with the HVAC system itself. Symptoms may include the system turning on and off repeatedly, inconsistent temperatures, or strange noises coming from the unit.
Some potential solutions include checking the circuit breaker, ensuring the thermostat is properly connected and functioning, and inspecting the HVAC system for any loose connections, debris, or other issues. However, if the problem persists or you're not comfortable troubleshooting the issue yourself, it's best to call a professional HVAC technician to diagnose and repair the problem.
