True or False: The higher the humidity, the more system capacity is used to remove moisture.

The correct assertion is that the higher the humidity, the more system capacity is used to remove moisture. This stems from the fundamental principles of how HVAC systems operate. When humidity levels in the air increase, there is a greater amount of moisture that the system must contend with.

In cooling systems specifically, humidity affects the dehumidification process, which often takes place as part of the cooling cycle. When the air is more humid, the cooling system must work harder to condense the moisture from the air. This requires additional energy and effectively uses more of the system's capacity to achieve the desired indoor climate and comfort level.

While heating systems may also indirectly involve humidity control (primarily in terms of maintaining comfort and reducing condensation), the direct correlation between humidity levels and system capacity is most pronounced in cooling systems, where the removal of moisture is critical during high-humidity conditions. Therefore, emphasizing that capacity is tied to humidity contributes to the overall efficiency and effectiveness of heating, ventilation, and air conditioning operations.
