What Is An Air Handler?

What is an Air Handler?

An air handler is a crucial component of an HVAC (Heating, Ventilation, and Air Conditioning) system. It is responsible for regulating and circulating air as part of the heating and cooling processes.

Key Functions

Air Circulation: It moves air throughout a building, ensuring even distribution of temperature and air quality.

Heating and Cooling: The air handler can work with heating and cooling coils to adjust the temperature of the air before it’s distributed.

Filtration: It often includes filters that remove dust, allergens, and other particles from the air, improving indoor air quality.

Main Components

Blower: A fan that pushes air through the system and into the ducts.

Coils: Heating and cooling coils where air is conditioned.

Filters: To capture airborne particles and contaminants.

Dampers: To control airflow and regulate temperature.

Controls: Thermostats and sensors that manage the operation of the air handler.

Types of Air Handlers

Modular Air Handlers: Flexible units that can be customized for specific needs.

Rooftop Units: Installed on rooftops and often used in commercial applications.

Fan Coil Units: Smaller units that are typically found in residential settings.

Applications

Residential: Used to condition air in homes.

Commercial: Found in office buildings, shopping centers, and industrial facilities for large-scale air management.

Benefits

Energy Efficiency: Properly designed air handlers can help reduce energy consumption.

Improved Air Quality: Filtration and ventilation contribute to healthier indoor environments.

Comfort: Provides consistent heating and cooling, enhancing overall comfort.
