What can result from poor airflow in an HVAC system?

In an HVAC system, poor airflow can lead to increased energy consumption because the system must work harder to maintain the desired temperature. When airflow is obstructed, whether due to dirty filters, closed vents, or duct leaks, the heating or cooling equipment has to run longer than necessary to compensate for the inadequate distribution of air. This extended operation results in higher energy use and increased utility bills. Therefore, it is essential for efficient HVAC performance that the airflow remains unobstructed and properly balanced throughout the system. Improved airflow contributes to reduced energy use and more effective climate control in the space.
