Your Heating as well as A/C system’s air handler is a unit used to produce conditioned air as well as transfer that air all over the rooms of your home, but air handlers come in many sizes as well as shapes however commonly take a fan, coil, as well as fan enclosed in a giant metal box… Their primary job is to condition the air inside your home, cleaning as well as conditioning the indoor air is the key distinction of an air handler unit.
Technically, it doesn’t need to provide the source of cooling, but your air handler unit comprises a fan that blows air through a filter as well as a heat exchanger in its simplest form.
To achieve this, the fan in the air handler pulls unconditioned air from the indoor space within your house or building, some air handler units also pull in outdoor air to ensure that there is consistently fresh, clean air in your indoor space as well as not the same recycled air over as well as over again; Bringing fresh air into your indoor space is essential in preventing stale air as well as high carbon dioxide levels. The outside air as well as return air both come into a component of your air handler known as a plenum. The mixing plenum is a compartment where the more than one airflows mix before traveling through the rest of your AHU. The mixed air will then pass over a filter that traps contaminants, leaving only clean, healthy air to pass as well as then through the heat exincreasing coil, which heats or cools the air in the process, depending on the genre of your air handler.
