Which of the following is a common symptom of HVAC duct leakage?

• A. Consistent temperature distribution
• B. Decreased energy bills
• C. Excessive noise from the HVAC system
• D. Improved air quality

Answer: (C)

Excessive noise from the HVAC system is indeed a common symptom of duct leakage. When there are leaks in the ductwork, the system may struggle to maintain the desired airflow. This can create a situation where the blower and other components work harder than designed, resulting in increased noise levels. Additionally, the leaking air can lead to turbulence and irregular pressure within the ducts, further contributing to the sounds of the system, which may include whistling, rattling, or a general increase in operational noise. Recognizing this symptom is important for diagnosing issues related to duct leakage, as it can impact both the system's efficiency and the comfort level within the building. Other options, such as consistent temperature distribution, decreased energy bills, and improved air quality, typically indicate an HVAC system operating efficiently without leaks. In fact, duct leakage often leads to the contrary; temperature imbalances, increased energy costs due to inefficiency, and compromised air quality due to unconditioned air entering the system or escaping from it.
