What is a common reason for inspecting duct systems in homes?

Inspecting duct systems in homes primarily focuses on assessing airflow efficiency. Ducts play a crucial role in a building's heating, ventilation, and air conditioning (HVAC) system by distributing conditioned air throughout the space. Properly functioning and well-designed ductwork can significantly influence energy efficiency, indoor air quality, and overall comfort levels in the home.

When inspecting duct systems, several factors are examined to ensure that air flows freely and efficiently. This includes checking for blockages, leaks, and the condition of duct insulation. Ensuring optimal airflow helps prevent energy loss and maintains the effectiveness of HVAC systems, allowing them to operate at their intended capacity.

The other options such as verifying structural integrity, ensuring compliance with aesthetic standards, and evaluating insulation materials, while relevant in other contexts, do not directly address the primary function of duct inspection specifically related to airflow delivery and efficiency.
