What is typically the consequence of a dampers failure during a pressure test?

When dampers fail during a pressure test, the most significant consequence is the impact on the accuracy of pressure readings. Dampers are designed to control airflow in HVAC systems, and if they malfunction, they can allow unwanted air leakage or restrict airflow, leading to misleading pressure measurements. Accurate pressure readings are crucial for assessing the building's airtightness and identifying potential areas for improvement.

Inaccurate data can result in incorrect conclusions about the building's performance, potentially leading to ineffective solutions for improving energy efficiency and comfort. Therefore, understanding the role of dampers in the pressure testing process highlights their importance in ensuring that the results reflect the true airtightness of the building.

The other options do not align with the effects of damper failure. For instance, a malfunctioning damper would not enhance indoor air quality or energy efficiency, nor would it have no impact; it fundamentally alters the testing outcomes.
