If you’re searching for heating and cooling services, you may come across confusing, sometimes contradictory information about a variety of HVAC systems. One element that garners a lot of confusion is the air handler. Is this another way to describe an air conditioner? We’re here to help sort this out.
An air handler is the indoor component of some types of HVAC systems. It attaches to a network of air ducts that circulate conditioned air through the building. Air handlers vary in size, type and capacity, dependent on the application.
Some individuals use the terms “air handler” and “blower” interchangeably, but this is not right. An air handler is an entire unit containing a blower and numerous other parts, all of which work together to condition and circulate the air.
Generally, an air conditioner [shares|uses|utilizes} the furnace’s blower motor, so no air handler is needed. However, in weather where home heating is not required, an air conditioner may be the sole HVAC equipment present. In this situation, the indoor air handler runs in tandem with the outdoor unit, called the condenser.
In this setup, the AC unit’s air handler [blows|forces|pushes} indoor air [across|over|along the outside of} the evaporator coil, which absorbs heat and collects moisture, leaving the air handler to circulate cooled, dehumidified air back inside the building using ductwork. Refrigerant lines connect the air handler to the outdoor condenser, facilitating the heat transfer to the outside. This will permit the air conditioning to maintain a constant, comfy indoor temperature and humidity level.
This is where air handlers are most typically found. In cold climates where heat pumps are less effective, they are sometimes installed alongside furnaces, creating what’s called a dual-fuel system. However, advancements in cold-climate heat pumps make dual-fuel systems less popular as of late. Because there is no furnace to lend its blower motor, heat pumps require a dedicated air handler to disperse conditioned air.
Heat pumps work by removing heat from the outside air and transferring it inside through the indoor coil. The air handler blows air across the coil to acquire heat before circulating it inside the building. A heat pump can also be used for cooling, where it extracts heat from the indoor air and transfers it outside, just like an air conditioner.
No. Furnaces are made with a blower motor to circulate conditioned air. The blower is usually found within the furnace. It forces air across the heat exchanger, a metal component that exchanges heat from a fuel source to the air blowing past it. The fuel source can be natural gas, propane or oil, which is ignited to create heat. Once heated, the air circulates back through the ductwork system and inside the building.
The main parts of an air handler include:
