Types of Air Handlers in HVAC Systems
In this section, we will explore the different types of air handlers that are used in HVAC systems. Understanding the various types of air handlers available is essential when choosing the right unit for your HVAC needs.
Packaged Units:
One type of air handler commonly found in HVAC systems is the packaged unit. These all-in-one systems include both heating and cooling components. Packaged units are a convenient and space-saving option as they house all the necessary equipment in a single unit. They are typically installed outside the home and connect to ductwork to deliver conditioned air throughout the space.
Split Systems:
Another type of air handler is the split system. Split systems consist of an outdoor component called the condenser and an indoor component known as the evaporator coil. The condenser unit is responsible for cooling the refrigerant, while the evaporator coil facilitates the heat transfer process. These components work together to deliver conditioned air to different areas of the home.
Fan Coil Units:
Fan coil units are energy-efficient air handlers that can contain heating coils, cooling coils, or both. These units work by using a fan to circulate conditioned air throughout the space. Fan coil units are commonly found in commercial buildings and multi-unit residential properties. They offer flexibility and can be tailored to meet specific heating and cooling needs.

|---|---|
| Packaged Units | All-in-one systems that include heating and cooling components. Installed outside the home. |
| Split Systems | Consist of an outdoor component (condenser) and an indoor component (evaporator coil) that work together to deliver conditioned air. |
| Fan Coil Units | Energy-efficient air handlers that can contain heating coils, cooling coils, or both. Use a fan to circulate conditioned air. |
How an Air Handler Works Within Your HVAC Ecosystem
In this section, we will explore how an air handler works within your HVAC ecosystem. The air handler plays a vital role in maintaining optimal indoor comfort by collaborating with condensers and utilizing refrigerants for efficient heat exchange. Understanding the heating and cooling dynamics involved in the air handler’s functionality will give you insight into its importance in your HVAC system.
Collaboration with Condensers, Refrigerants: Essential for Heat Exchange
The air handler works in collaboration with condensers to ensure effective heat exchange. Condensers are responsible for cooling the refrigerant, which then flows to the air handler. In the air handler, the refrigerant absorbs heat from the air, cooling it down, while the refrigerant itself becomes heated. This heat is then transferred back to the condenser, where it is released into the outdoor environment. This continuous process of heat exchange enables the air handler to regulate the temperature indoors.
From Hot to Cold: Heating and Cooling Dynamics
The air handler’s heating and cooling dynamics are made possible through the use of refrigerants. When heating is required, the refrigerant absorbs heat from the outdoor environment and transfers it to the air handler. The air handler then utilizes a heating element to warm the air before distributing it throughout the home. In the cooling mode, the refrigerant absorbs heat from the indoor air and releases it into the outdoor environment, resulting in a cooler indoor temperature. The air handler’s blower fan plays a crucial role in circulating the conditioned air, ensuring consistent comfort throughout your home.
By understanding how an air handler works within your HVAC system, you can appreciate its significance in maintaining optimal indoor comfort. The collaboration with condensers, the utilization of refrigerants for heat exchange, and the heating and cooling dynamics all contribute to the air handler’s functionality.
