True or False: An unbalanced duct system will cause the temperatures to be the same in all rooms.

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

Answer: (C)

Not true. An unbalanced duct system causes uneven temperatures in different rooms because the airflow to each space isn’t the same. When some rooms receive more conditioned air than others, they heat up or cool down faster and reach their thermostat setpoints sooner, while rooms with less air get less conditioning and stay warmer or cooler longer. This creates hot spots and cold spots throughout the building. The purpose of balancing the ducts is to adjust dampers, check duct sizing and leaks, and ensure each room gets a roughly designed share of airflow so temperatures stay more uniform. Other factors like insulation, sun exposure, and occupancy can also affect room temperatures, but an unbalanced duct system is a primary driver of nonuniform comfort.
