What is an air handler? An air handler, also referred to an air handling unit, may be abbreviated to AHU.

The air handler is made up of a blower, heating or cooling elements, filter racks or chambers, sound attenuators and dampers.

How do air handlers work with my HVAC system? Air handlers, in many cases, are connected to your ductwork ventilation system. This system distributes the conditioned air throughout your home and returns it to your air handler.

What types of air handlers are there? Air handlers can be both small and large. Small air handlers can be referred to as terminal units and typically consist of an air filter, coil and blower. Larger units condition 100 percent of outside air and are referred to as makeup air units. There is also an air handler model designed solely for outdoor use. These units can withstand the elements, are typically installed on roofs and are known as a packaged unit or rooftop unit (RTU).
