True or False: A system with too little air flow can result in high duct temperatures.

A system with too little airflow can indeed lead to high duct temperatures. This is because proper airflow is essential for effective heat transfer within an HVAC system. When there is insufficient airflow, the system cannot efficiently remove heat from the air, causing the temperatures in the ducts to rise.

In situations where the airflow is restricted, the air isn't able to circulate as intended, which can result in hot spots forming within the ductwork. This can lead to inefficiencies in the system and may cause components to overheat, potentially leading to equipment failure or reduced lifespan.

This phenomenon is not limited to specific weather conditions, making the options that refer to only winter months or extreme weather situations less applicable. High duct temperatures can occur regardless of external conditions if airflow is inadequate, reinforcing the statement's validity. Therefore, indicating that it is true reflects an accurate understanding of how HVAC systems function when airflow is suboptimal.
