Alliance Air Handlers

How Important Is Your Air Handler?
An Air Handling Unit (AHU) is a device that takes air from the outdoors and distributes it throughout a building. It does this by taking air from outside, cleaning it, heating or cooling it, possibly humidifying it, and then forcing it through ducts to the different parts of the building. When air handlers are designed improperly or parts start to fail, occupant comfort or manufacturing processes can become impeded, causing a great deal of frustration for everyone.
