Air Handler

Nov. 21, 2022

An air handler, or air handling unit (AHU), is a device used to regulate and circulate air as part of a heating, ventilating, and air-conditioning (HVAC) system. An AHU pulls in outside air, recirculates interior air, or both.

 

The three main functions of an air handler are:

 

To move air throughout the building

 

To condition the air (i.e. heat or cool it)

 

To filter the air of dust, pollen, and other particles

 

 

An AHU typically consists of a blower, heating and/or cooling coils, and filters. Some units may also include a humidifier, dehumidifier, or electrostatic air cleaner.

 

AHUs are usually located in the basement or an equipment room, and they are connected to the HVAC system’s ductwork. When used in conjunction with a furnace, an AHU is often referred to as a “furnace blower.”

 

What are the benefits and advantages of using an Air Handler?

 

There are several benefits and advantages to using an air handler as part of your HVAC system, including:

 

Improved air circulation: An AHU circulates air throughout the building, which can improve indoor air quality by reducing stagnant air.

 

An AHU circulates air throughout the building, which can improve indoor air quality by reducing stagnant air. Enhanced comfort: By evenly distributing conditioned air, an AHU can help to create a comfortable indoor environment.

 

By evenly distributing conditioned air, an AHU can help to create a comfortable indoor environment. Greater efficiency: An AHU is more efficient than a furnace or air conditioner alone, as it can provide both heating and cooling.

 

An AHU is more efficient than a furnace or air conditioner alone, as it can provide both heating and cooling. Increased lifespan: By circulating air and removing dust and other particles from the air, an AHU can help to extend the life of your HVAC system.

 

What are some common problems with Air Handlers?

 

There are a few common problems that can occur with air handlers, including:

 

Dirty filters: If the air handler’s filters are dirty, they can restrict airflow and reduce efficiency.

 

If the air handler’s filters are dirty, they can restrict airflow and reduce efficiency. Frozen coils: If the coils in the air handler freeze, they can cause the unit to stop working properly.

 

If the coils in the air handler freeze, they can cause the unit to stop working properly. Thermostat issues: If the air handler’s thermostat is not working properly, it can cause the unit to cycle on and off frequently or not provide enough heating or cooling.

 

If the air handler’s thermostat is not working properly, it can cause the unit to cycle on and off frequently or not provide enough heating or cooling. Leaks: If there are leaks in the air handler, it can reduce efficiency and allow conditioned air to escape.

 

An air handler is a vital part of any HVAC system, and it can provide many benefits and advantages. However, like any other piece of equipment, air handlers can experience problems from time to time. If you have any concerns about your air handler, or if it is not working properly, be sure to contact a qualified HVAC technician for assistance.

 

What are the disadvantages of using an Air Handler?

 

There are a few potential disadvantages of using an air handler, including:

 

Higher initial cost: Air handlers can be more expensive to purchase and install than other types of HVAC systems.

 

Air handlers can be more expensive to purchase and install than other types of HVAC systems. Requires ductwork: Air handlers require a system of ducts to distribute conditioned air throughout the building, which can add to the initial cost and complexity of the installation.

 

Air handlers require a system of ducts to distribute conditioned air throughout the building, which can add to the initial cost and complexity of the installation. Limited climate control: Air handlers are not as effective at controlling humidity levels as some other types of HVAC systems.

 

Despite these potential disadvantages, air handlers offer many benefits and advantages that can outweigh the cost and complexity of installation. If you are considering an air handler for your home or business, be sure to contact a qualified HVAC contractor to discuss your options.
