The answer to 'my inspection won't turn on' is that there could be several common causes, including a tripped circuit breaker, a faulty thermostat, or an issue with the HVAC unit itself. This can result in symptoms like the system not powering on, the fan not running, or the unit not producing any heat or cooling.
For a tripped circuit breaker, you can try resetting it. If that doesn't work, you may have an electrical issue that requires a professional HVAC technician to diagnose and repair. A faulty thermostat may need to be replaced, which is a relatively simple DIY task if you're comfortable working with low-voltage electrical components. However, if the issue is with the HVAC unit, it's best to call in a licensed professional to properly inspect and service the system.
