What is an Air Handler or Air Handling Unit?
An air handler, or air handling unit (AHU), is a central unit consisting of a blower, heating and cooling elements, filter racks or chamber, dampers, humidifier, and other central equipment in direct contact with the airflow. This does not include the ductwork through the building. It is often abbreviated as AH or AHU.
Air handlers are used to distribute conditioned air throughout a building. The type and size of an air handler depends on the size of the building, the climate, and the type of HVAC system. Air handlers can be either mechanical or electronic.
Mechanical air handlers use fans to push conditioned air through the building. The advantage of mechanical air handlers is that they can be used with a variety of heating and cooling systems.
Electronic air handlers use a motor to turn a fan, which pushes the conditioned air through the building. The advantage of electronic air handlers is that they are more efficient than mechanical air handlers.
What is the difference between an air conditioner and an air handler?
An air conditioner is a piece of equipment that cools the air in a building. An air handler is a piece of equipment that distributes conditioned air throughout a building. So, an air handler can include an air conditioner, but an air conditioner cannot include an air handler.
What is the difference between an air handler and a furnace?
A furnace is a piece of equipment that heats the air in a building. An air handler is a piece of equipment that distributes conditioned air throughout a building. So, an air handler can include a furnace, but a furnace cannot include an air handler.
What are the Components of an Air Handler?
The components of an air handler vary depending on the type of air handler. However, common components include a blower, heating and cooling elements, filter racks or chamber, dampers, humidifier, and other central equipment.
What are the benefits of an electronic air handler?
The benefits of electronic air handlers include increased efficiency and longer life. Electronic air handlers are more efficient than mechanical air handlers because they use a motor to turn a fan. This allows the fan to move more air with less power. Electronic air handlers also have a longer life than mechanical air handlers because there is less wear and tear on the motor.
How are Air Handlers Installed?
Air handlers are typically installed in the same room as the furnace. However, they can also be installed in other parts of the building, depending on the needs of the building. Air handlers are typically installed on a wall or the ceiling by an HVAC contractor.
