The answer to 'my ductwork keeps shutting off' is that there are several common causes, including a problem with the thermostat, a blocked air filter, leaks in the ductwork, or issues with the HVAC unit itself. Symptoms may include uneven heating or cooling, high energy bills, and the system shutting off unexpectedly.
Some DIY solutions you can try include checking the air filter and replacing it if it's dirty, inspecting the ductwork for any visible leaks or damage, and ensuring the thermostat is set properly. However, if the problem persists or you're not comfortable troubleshooting the issue, it's best to call a professional HVAC technician to diagnose and fix the problem. They have the expertise and tools to properly identify and resolve the issue with your ductwork.
