What is the primary function of an air handler in an HVAC system?

The primary function of an air handler in an HVAC system is to circulate and condition air. An air handler plays a crucial role in managing indoor air quality and temperature by facilitating the flow of air throughout a building. It is equipped with a fan that moves air, and often includes heating and cooling components, allowing it to condition the air to maintain a desired temperature and humidity level.

Additionally, air handlers can incorporate filters that trap various airborne particles, but their main role goes beyond just filtering; it involves actively managing air movement and treatment. While removing humidity is a function that can happen within an air handler’s capabilities, it is not the sole purpose. The air handler primarily ensures that conditioned air is distributed effectively to various spaces, making it central to the overall HVAC operation.
