What is one consequence of inadequate ventilation in an HVAC system?

• A. Reduced energy efficiency
• B. Improved indoor air quality
• C. Increased humidity levels
• D. Extended equipment lifespan

Answer: (A)

Inadequate ventilation in an HVAC system leads to reduced energy efficiency because the system has to work harder to maintain desired temperature levels without proper airflow. When there is insufficient ventilation, the distribution of treated (heated or cooled) air becomes uneven, leading to hot or cold spots within a space. This imbalance forces the HVAC unit to operate longer and, in some cases, at higher capacities to compensate for the lack of adequate air movement, thereby increasing energy consumption. In contrast, improved indoor air quality typically requires adequate ventilation to dilute pollutants and maintain healthy air standards; therefore, it would not be a consequence of inadequate ventilation. Increased humidity levels can result from inadequate ventilation, but not in all cases, as it depends on external factors and the HVAC system's configuration. While extended equipment lifespan can be associated with proper maintenance and operation, inadequate ventilation typically leads to increased wear and tear on the system due to overwork, thus potentially reducing lifespan instead of extending it.
