What is a common symptom of a dirty air filter?

• A. Increased airflow
• B. Reduced airflow
• C. Unusual noise from the system
• D. Higher energy bills

Answer: (B)

A common symptom of a dirty air filter is reduced airflow. When an air filter becomes clogged with dust, dirt, and other particulates, it obstructs the passage of air through the HVAC system. This blockage can significantly decrease the amount of air that can flow through the ducts, leading to reduced airflow in the conditioned space. The consequences of reduced airflow can be quite severe, affecting the efficiency of the heating and cooling systems and leading to an inability to maintain the desired temperature within the building. It can also put additional strain on the system components, which may result in further operational issues. Regular maintenance, including replacing or cleaning the air filter, is necessary to avoid these problems and ensure optimal performance of the HVAC system.
