What are 3 components typically associated with a forced air air handling unit?

• A. Duct work, heating-cooling coils, humidifiers
• B. Duct work, boilers, humidifiers
• C. Pipes, heating coil, fans
• D. Duct work, insulation, dampers

Answer: (A)

The main idea is understanding what parts are typically built into a forced air air handling unit to condition and move air. The three components most commonly associated are duct work, heating and cooling coils, and a humidifier. Duct work provides the path to deliver conditioned air to and from spaces. The heating and cooling coils are the elements that actually temper the air to the desired temperature. The humidifier adjusts the humidity level to improve comfort and air quality. Other items like boilers are external heat sources, pipes aren’t a standard AHU component, and while dampers may be present, they don’t define the core trio used to describe a typical forced air AHU.
