Difference between AHU and FCU

Both an air handler unit (AHU) and a fan coil unit (FCU) are used in HVAC systems to control the temperature and airflow in a building. However, there are some key differences between the two units that you should know before choosing which one is right for your needs. In this blog post, we will discuss the main differences between AHUs and FCUs, so you can make an informed decision about which type of unit is best for your application. Stay tuned!

What is AHU?

AHU is an acronym for an air handling unit. AHUs are large pieces of equipment that are used in heating, ventilation, and air conditioning (HVAC) systems to regulate and circulate air. AHUs typically consist of a fan, filter, and heat exchanger. They are often located in the basement or attic of a building and connected to ductwork that runs throughout the structure. AHUs are important components of HVAC systems, as they help to ensure that the air in a building is clean, fresh, and comfortable.

What is FCU?

FCU stands for fan coil unit. FCUs are a type of HVAC equipment that is used to condition the air in buildings. FCUs consist of a fan, coils, and a controller. The fan blows air over the coils, which cools or heats the air depending on the setting. The controller regulates the fan speed and coil temperature to maintain the desired indoor temperature. FCUs are often used in office buildings, hotels, and other commercial buildings. They are also used in some residential applications. FCUs are available in a variety of sizes and configurations to suit different needs.

Difference between AHU and FCU

AHU and FCU are both types of HVAC units. AHU stands for Air Handling Unit, while FCU stands for Fan Coil Unit. AHUs are typically used in commercial settings, while FCUs are more commonly used in residential settings. AHUs generally include a fan, coils, and a filter, while FCUs usually just include a fan and coils. AHUs are more powerful than FCUs and can cool or heat a larger space more effectively. FCUs are less expensive than AHUs, though, so they may be a better option for small spaces or budget-conscious consumers. When choosing an HVAC unit, it is important to consider the specific needs of your space and choose the unit that will best meet those needs.


FCUs and AHUs are two different types of air handling units. FCUs blow conditioned air directly into the space, while AHUs condition and distribute the air to multiple spaces. The type of unit you need depends on a few factors, like the size of your building and how many people you want to be able to cool or heat simultaneously.
