The statement 'Temperatures in all rooms are the result of an unbalanced duct system' is:

• A. Sometimes
• B. Not sure
• C. False
• D. True

Answer: (C)

Temperatures in a building are shaped by how air is distributed, but it’s not true that all room temps are determined solely by an unbalanced duct system. An unbalanced system can cause some rooms to be warmer or cooler than others, but many other factors affect room temperature: insulation levels, window placement and shading, heat loads from people and equipment, thermostat location, and duct leaks or restrictions. Balancing the ducts aims to match airflow to each room’s load, reducing large differences, but it doesn’t guarantee every room will end up with the same temperature. So the statement is not accurate.
