What Is An Air Handler Vs Condenser?

Air Handler (AHU)

Function: Responsible for circulating and conditioning air within a building.

Components:

Blower/Fan: Moves air through the system.

Heating and Cooling Coils: Adjust air temperature.

Filters: Clean the air of dust and allergens.

Dampers: Control airflow.

Location: Typically located indoors, often in attics, basements, or dedicated mechanical rooms.

Role: Works with both heating and cooling systems to maintain indoor air quality and comfort.

Condenser

Function: Part of the cooling system, responsible for releasing heat absorbed from the indoor air.

Components:

Compressor: Pumps refrigerant through the system.

Coils: Release heat as refrigerant condenses from gas to liquid.

Fan: Helps dissipate heat into the outside air.

Location: Usually located outdoors, often mounted on the ground or on rooftops.

Role: Primarily involved in the cooling process by rejecting heat from the refrigerant after it has absorbed heat from inside the building.

Key Differences

Purpose: The air handler conditions and circulates air, while the condenser removes heat from the refrigerant.

Location: Air handlers are typically indoors, while condensers are located outdoors.

Operation: Air handlers work continuously to maintain indoor comfort, while condensers operate during the cooling cycle to expel heat.

Both components are crucial for the efficient operation of an HVAC system, working together to provide a comfortable indoor environment. If you have more questions or need further clarification, feel free to ask!
