How can airflow issues in an A/C system be identified?

Identifying airflow issues in an A/C system often involves monitoring for uneven cooling and unusual noises. When an air conditioning system is functioning properly, it delivers consistent and evenly distributed cool air throughout the space. If certain areas remain warm while others are cool, this can indicate a blockage or restriction in the airflow, such as dirty filters, closed vents, or ductwork problems.

Unusual noises can also be a significant indicator of airflow issues. For example, sounds such as hissing, rattling, or whistling may suggest that there are obstructions in the ducts or problems with the blower motor. Monitoring these signs helps technicians pinpoint specific airflow problems, leading to more effective troubleshooting and repairs.

While factors like warm air and humidity levels, duct size, and unit age may provide context about the system's performance, they do not directly indicate airflow issues as clearly or specifically as observing uneven cooling and noises.
