How can blocked supply registers affect a ventilation system's efficiency?

• A. They can increase airflow
• B. They can restrict airflow
• C. They can enhance air quality
• D. They can lower energy costs

Answer: (B)

Blocked supply registers can significantly restrict airflow within a ventilation system. When these registers are obstructed, whether by furniture, debris, or other items, the air cannot freely flow through the ductwork into the conditioned spaces of a building. This reduction in airflow can lead to several inefficiencies, such as uneven distribution of air throughout the building, resulting in some areas being inadequately ventilated while others may feel drafts. Consequently, the heating or cooling systems may have to work harder to maintain the desired temperature, which not only decreases overall system efficiency but can also lead to increased energy costs over time. Proper airflow is essential for maintaining optimal indoor air quality and ensuring that the HVAC system operates effectively. Thus, addressing any blockages in supply registers is crucial for the overall performance of a ventilation system.
