What do pressure changes in a home indicate?

Pressure changes in a home are primarily indicative of airflow dynamics. When air moves in or out of a building, it causes changes in air pressure that can signal how air is flowing through different spaces within the structure. This can be influenced by several factors, including the operation of exhaust fans, heating or cooling systems, and the design of the home itself. Understanding airflow dynamics is crucial for assessing indoor air quality, energy efficiency, and moisture control, which are all essential components for creating a comfortable and healthy indoor environment.

While humidity levels, temperature fluctuations, and construction integrity can all play roles in the overall performance of a home, they do not directly relate to the immediate changes in pressure that signal specific airflow issues. For instance, humidity can affect comfort levels but isn't a direct result of pressure changes, and temperature fluctuations may exist due to thermal dynamics rather than air movement. Similarly, construction integrity pertains to the physical state of the building components rather than the dynamic behavior of air within it. Thus, recognizing the role of airflow dynamics allows for a better understanding of potential issues related to building performance and indoor environmental quality.
