Which of the following is NOT required to be inspected in the Air Conditioning systems?

The correct choice highlights that electric air cleaning devices are not required to be inspected as part of the air conditioning systems assessment. The focus of a typical air conditioning inspection is primarily on the components that directly affect the cooling function of the system, which includes permanently installed cooling equipment, ground-source cooling systems, and window cooling units. These components have a direct impact on the operation and performance of the overall air conditioning system.

Electric air cleaning devices, while they play a role in improving indoor air quality, do not function as part of the cooling mechanism itself and are often considered supplementary. Therefore, they are not included in the mandatory inspection for air conditioning systems defined by home inspection standards.

This distinction is important for home inspectors to understand, as it allows them to focus their assessments on the components that are essential for maintaining the cooling functionality and efficiency of HVAC systems.
