What can be a symptom of inadequate air flow in an air conditioning system?

Inadequate air flow in an air conditioning system can lead to increased humidity levels, which is a significant symptom. When air flow is restricted, the system struggles to effectively dehumidify the air as it passes over the evaporator coil. This occurs because the moisture in the air is not sufficiently condensed and drained away, leading to higher humidity inside the conditioned space. An air conditioning system is designed to not only cool the air but also to remove moisture, and when air flow is compromised, its ability to do so is diminished, resulting in a more humid environment.

The other symptoms related to air flow issues, such as frost build-up or variations in pressure readings, may occur due to specific conditions in the system but do not directly relate to humidity perception in the space. Additionally, the cycling frequency of the compressor may also vary based on other operational factors, further complicating its relationship to air flow. Hence, increased humidity is a clear and direct indication of inadequate air flow.
