In verifying HVAC system installations, inspectors commonly check for what?

Inspectors checking HVAC system installations focus extensively on identifying leaks in ductwork and ensuring that units are properly placed and functioning as intended. This is critical because leaks can significantly impact the efficiency and performance of the heating and cooling system, leading to increased energy costs and reduced indoor air quality. Proper placement of units is also essential for effective airflow, allowing the HVAC system to operate at optimal levels and maintain desired temperature control throughout the building. These practical, functional assessments ensure that the system not only meets building codes but also serves its purpose effectively.

While efficiency ratings and compliance with manufacturer specifications are also important factors, they are secondary to the first-hand operational assessment of the system's installation and function. Visual aesthetics, while visually appealing, do not impact the performance and safety of the HVAC system directly, making them less critical during inspections. Therefore, the primary focus of inspectors is on the functionality and practicality of the HVAC installation, supporting the selection of the correct answer.
