True or False: Ventilation only happens when the air handler is operating.

Ventilation refers to the process of introducing fresh outdoor air into a building while also removing stale indoor air. The statement suggests that ventilation is solely dependent on the operation of the air handler, which is not entirely accurate.

In many HVAC systems, natural ventilation can occur without the air handler being active. For instance, if windows or vents are open, fresh air can enter the space, even if the air handler is not functioning. This natural airflow would still allow for some level of ventilation to take place.

Additionally, mechanical systems might operate with fans or other components that facilitate airflow and ventilation independent of the main air handler. This means that while mechanical ventilation relies heavily on the operation of the air handler, natural ventilation can happen without it, causing the assertion to be overly simplistic.

Therefore, the correct perspective is that ventilation can occur whether the air handler is operating or not, making the assertion false.
