Did you know some air handlers have an airside economizer mode that will delay or eliminate the need for mechanical cooling if the outside air is cooler? The components, in an HVAC system, ensure that the air in this space is clean and odor free, and that its temperature, humidity and circulation rate are maintained within desired ranges. This interactive online course cover the components of an air handler, the operational functionality of an air handler, the methods of air handler maintenance, and the benefits and operation of an outside air economizer.
