The answer to 'my ductwork keeps shutting off' is that there are several common causes, including a malfunctioning thermostat, blocked or leaky ducts, and issues with the HVAC system itself. Symptoms may include uneven temperatures, high energy bills, and the system turning on and off frequently.
Some possible solutions include checking the thermostat settings, sealing any duct leaks, and cleaning or replacing air filters. However, if the problem persists, it's best to call a professional HVAC technician to diagnose and fix the issue, as they have the expertise and tools to properly identify and address the root cause.
