If high levels of carbon monoxide are detected at the furnace supply registers, what should the inspector do first?

• A. Advise that everyone run out of the house for safety
• B. Immediately shut off the main gas valve to disable the unit
• C. Explain that the unit will need servicing in the future
• D. Shut down the system, open the windows, and advise immediate evaluation by an HVAC contractor

Answer: (D)

The correct action in this scenario is to shut down the system, open the windows, and advise an immediate evaluation by an HVAC contractor. This approach addresses the immediate safety concern of elevated carbon monoxide levels, which is a dangerous gas that can cause serious health risks, including poisoning. By shutting down the system, the source of carbon monoxide can be stopped, preventing further exposure. Opening the windows helps to ventilate the space, allowing fresh air in and reducing the concentration of carbon monoxide. This is critical in a situation where occupants may still be inside the home. Advising immediate evaluation by an HVAC contractor is essential because it ensures that a professional with the expertise can diagnose and fix the problem effectively. This response prioritizes the safety of the occupants and addresses the urgent need for proper ventilation and professional evaluation of the furnace system, ensuring that the source of carbon monoxide is identified and mitigated.
