Air Handler

air handlerFinding an air handler in Charlotte is critical to having an optical HVAC system. Usually, an air handler is a large metal box containing a blower, heating and/or cooling elements, filter racks or chambers, sound attenuators and dampers.

An air handler usually connect to ductwork that distributes the conditioned air throughout the home and returns it to the air handler. Sometimes, an air handler discharges and admits air directly to and from the space served without necessary ductwork.

Air handlers typically are comprised of:

Blower/fan: Usually located in a large squirrel-cage blower that is driven by an electric motor to move the air. The blower may operate at a single speed, offer a variety of pre-set speeds or be driven by a variable drive so as to allow a wide range of air flow rates.

Heating and/or cooling elements: Depending on the location and the application, air handlers may need to provide heating, cooling or both to change the supply air temperature.

Filters: Air filters are almost always present and needed in an air handling unit in order to provide clean, dust-free air to the home interior.

Humidifier: A humidifier is often necessary in colder climates where continuous heating will make the air drier, resulting in uncomfortable air quality and increased static electricity.

Mixing chamber: To maintain indoor air quality, some air handlers commonly bring outdoor air into the home as indoor air is exhausted out of the home. A mixing chamber is used with dampers to control the ratio between the return, outside and exhaust air.

Controls: Controls are necessary to regulate every aspect of an air handling unit, such as: flow rate of air, supply air temperature, mixed air temperature, humidity and air quality. Common control components include: temperature sensors, humidity sensors, sail switches, actuators, motors and controllers.

Vibration isolators: Since blowers in an air handling unit can create substantial vibration, vibration isolators are normally inserted into the duct immediately before and after the air handler, and often also between the fan compartment and the rest of the air handler.

An air handler is usually located in the garage, a closet or in the attic unless it is part of a package unit, in which case the air handler is incorporated into the system. The air handler can be an up-flow air handler, down-flow air handler or a horizontal-flow air handling unit.
