If you encounter open duct work in a garage, what conclusion should you draw for the report?

When encountering open duct work in a garage, it's important to recognize the potential for serious issues that can arise from this situation. Open ducts can facilitate the transfer of harmful gases, including carbon monoxide (CO), from vehicles into the home’s ventilation system. Vehicles often emit CO and other pollutants, especially when idling, and if duct work is left open, it can lead to these dangerous gases infiltrating the living areas of a home, thereby posing health risks to the occupants.

Carbon monoxide is colorless, odorless, and can be lethal in high concentrations. Home inspectors are trained to identify such risks and recommend appropriate measures to mitigate exposure, such as sealing ducts or ensuring that any vehicle exhaust is properly vented away from living spaces.

Understanding the implications of open duct work in a garage helps ensure the safety and health of occupants, making it essential to classify this observation as a serious issue rather than inconsequential or acceptable. Recognizing and reporting this risk accurately supports responsible home inspection practices and aids homeowners in maintaining a safe living environment.
