An air handler is a component of HVAC systems responsible for circulating conditioned air throughout a building. It contains components like a blower, heating or cooling coils, air filters, and dampers.

Modern air handlers are designed with energy efficiency and flexibility in mind. They can be part of various system configurations, including central heating and cooling, heat pump, and ductless systems.
