A fan coil unit, or FCU, uses a coil and fan to heat or cool a room without ductwork, making it suitable for individual room temperature control.

What is a Fan Coil Unit?

A fan coil unit (FCU) is a device used for heating or cooling a room without requiring ductwork. It comprises an indoor coil, a fan, and, in some systems, an outdoor condensing unit. The fan pushes air through the coil, which contains refrigerant to cool or heat the air, depending on the room’s temperature setting. FCUs are common in commercial spaces and some residential settings.

Types of Fan Coil Units

• Vertical Fan Coil Units (VFCs): Ideal for smaller spaces, VFCs can be mounted on walls or ceilings.
• Horizontal Fan Coil Units (HFCs): Better suited for larger areas, HFCs can be installed on floors or ceilings.

Fan Coil Units vs. Air Handling Units

While both devices are part of HVAC systems, fan coil units (FCUs) are standalone systems that circulate existing air within a space, often used in specific rooms or zones. Air handling units (AHUs) are larger and designed to cool and distribute air throughout a building via ductwork.

Cost of Replacing a Fan Coil Unit

Replacement costs for a fan coil unit range between $200 and $1,500, depending on the brand and unit size. Professional installation costs vary from $700 to $2,700. Regular maintenance helps prolong the unit’s lifespan and ensure optimal efficiency.

Do Fan Coil Units Use Refrigerants?

Yes, fan coil units use refrigerant within the indoor coil to cool or heat the air. As the fan operates, it forces air through the coil, where refrigerant either absorbs or releases heat. Since refrigerants can impact the environment if leaked, regular maintenance by our HVAC professional is essential to prevent leaks and maintain safe operation.
