What about systems that are shut off or de-energized at the time of the inspection?

Professional home inspectors will not turn on or restore service to any system that is shut off or not in service at the time of the inspection. Inspectors will not light standing pilot lights, energize electrical circuits that are shut off or out of service, or operate any water or gas in-line shut off valves. In order to inspect the plumbing, heating, cooling, and electrical systems of a home, the electrical service, water service, gas service and the components served by these utilities must be on and operational at the time of the inspection.
