What system is different from a natural-draft system, where the air passes naturally over the conditioning equipment?

Forced-air system
Radiant heating system
Geothermal system
Split-system

The correct answer is: Forced-air system

A forced-air system is different from a natural-draft system because it uses a fan to force air over the conditioning equipment for heating or cooling purposes. In contrast, a natural-draft system relies on the natural movement of air without a fan. Radiant heating systems work by heating objects in a room, such as floors or walls, rather than blowing heated air through ducts like a forced-air system. Geothermal systems rely on the earth's constant temperature to provide heating and cooling. A split-system refers to an HVAC system that has components both inside and outside the home, often with one part dedicated to cooling and another part for heating.
