Having an HVAC system with insufficient airflow can lead to increased energy costs and reduced comfort. When airflow is inadequate, the system struggles to distribute heated or cooled air throughout the space effectively. This not only causes the system to run longer in an attempt to reach the desired temperature, which in turn increases energy consumption and costs, but it also results in an uncomfortable environment for occupants. Areas may become too hot or too cold, leading to a lack of consistent and comfortable indoor climate conditions.

Furthermore, insufficient airflow can also strain the HVAC system, causing it to work harder than necessary, which may lead to more frequent breakdowns and higher maintenance costs over time. This also diminishes the overall performance and efficiency of the HVAC system, further exacerbating energy usage and comfort issues.

In contrast, options such as reduced humidity levels and improved air quality might not necessarily be the direct outcomes of insufficient airflow, and while longer lifespan of equipment may seem like a positive outcome, it is typically the opposite scenario; insufficient airflow tends to contribute to premature wear and tear on HVAC components.
