Air Handlers: An Overview

Air handlers are an essential component of any HVAC system, and understanding the role they play is key to making sure the system is operating at optimal efficiency. Air handlers are responsible for circulating air throughout a structure, maintaining a comfortable temperature, and filtering out dust and other airborne particles. By understanding the different types of air handlers and how they work, you can make sure your HVAC system is working to its fullest potential. This article provides an overview of air handlers and how they function in HVAC systems.

We’ll look at the different types of air handlers available and their respective roles in providing the best possible airflow and temperature control in your home or workplace. We’ll also explore the benefits of using air handlers and how to maintain them for optimal performance. Read on to learn more about air handlers and their importance in HVAC systems.

What is an Air Handler?

An Air Handler is a large, box-shaped piece of equipment used in HVAC systems for the purpose of regulating and circulating air. Air handlers are typically used to condition indoor air in large buildings or homes, but can also be used for automobile HVAC systems.

Air handlers consist of a blower, heaters, cooling elements, filter racks or chambers, sound attenuators, and dampers. The fan pulls air in from the outside and passes it through the filter where it is then heated or cooled depending on the desired temperature. The fan then circulates the air through the ducts, which distributes it throughout the building. The advantage of using an air handler is that it can heat or cool different areas of a building separately.

This allows for more efficient temperature control and better energy efficiency. Additionally, air handlers typically have less noise output than other HVAC components and require less maintenance.

In summary, an air handler is a large box-shaped piece of equipment used in HVAC systems to regulate and circulate air in order to condition indoor air in large buildings or homes.

Common Applications for Air Handlers

Homes and Commercial BuildingsAir handlers are a key component in HVAC systems, which are used to regulate the temperature and air circulation in buildings. In residential homes, air handlers can be used to cool and heat the air in a specific area.

Commercial buildings often utilize air handlers to provide heating and cooling solutions to entire buildings. In these cases, air handlers are used to regulate the air temperature and provide ventilation throughout the building.

Data Centers

Data centers require strict temperature control, as any deviation from the optimal temperature could cause serious damage to sensitive electronic components. Air handlers are used to maintain the desired temperature within a data center, as well as to ensure proper air circulation and air quality. Air handlers with enhanced filtration capabilities are commonly used in data centers to keep the air clean and free of dust or other particles.


In automobiles, air handlers are used to regulate the internal temperature and provide ventilation for passengers.

Automobile air handlers typically contain fans that can be set to different speeds depending on the desired airflow. In addition, most modern cars use air handlers that contain HEPA filters to remove pollen and other particles from the air.

The Benefits of Air Handlers

An air handler is an important component of any HVAC system, providing several key benefits. By conditioning air, air handlers help to improve indoor air quality, reduce energy costs, and enhance comfort levels. Here are the main benefits that come with using an air handler in a home or commercial building:Improved Air Quality: Air handlers help to improve the overall air quality in a building by removing dust, pollen, and other airborne particles from the air.

This helps to reduce the risk of respiratory illnesses and allergies, as well as providing a cleaner and healthier living environment.

Reduced Energy Costs:

Air handlers are designed to be energy efficient, helping to reduce energy costs. By using an air handler, you can save money on energy bills while also helping to reduce your carbon footprint.

Enhanced Comfort Levels:

An air handler helps to regulate the temperature inside a building, providing a comfortable environment all year round.

This helps to ensure that residents or employees are comfortable and productive in their work or living space.

Increased Lifespan of HVAC System:

By using an air handler, you can help to prolong the life of your HVAC system. This ensures that your heating and cooling system will remain in working order for many years to come. Air handlers are an essential component of HVAC systems, providing efficient and effective air regulation and circulation.

They are a great choice for conditioning indoor air in large buildings or homes, and can even be used in automobile HVAC systems. Air handlers offer several benefits, such as improved air quality, temperature control, and energy efficiency. They are also versatile and can be used in a variety of applications. With their advanced features and reliable performance, air handlers are an ideal choice for HVAC systems. This article has provided an overview of what air handlers are and how they work.

We have also discussed the benefits they offer, as well as some common applications. In conclusion, air handlers are an excellent choice for HVAC systems due to their reliability, efficiency, and versatility.
