Fan Coil Unit

A fan coil unit (FCU), or vertical fan coil unit (VFC), is a device that uses a coil and a fan to heat or cool a room without ductwork.

What is a Fan Coil Unit?

A fan coil unit (FCU) is a device used to heat or cool a room without the need for ductwork. It consists of an indoor coil, a fan and an outdoor condensing unit. The fan forces air through the indoor coil, which is filled with refrigerant, either cooling or heating it depending on the desired temperature in the room. This cooled or heated air is then sent into the room to maintain a comfortable environment. 
FCUs are often found in offices and other commercial buildings as well as some homes. There are two main types: vertical fan coils (VFCs) and horizontal fan coils (HFCs). VFCs are typically used for smaller spaces since they can be mounted vertically on walls or ceilings, while HFCs are more suitable for larger areas as they can be installed horizontally on the floor or ceiling.

What is the difference between a fan coil unit and an air handling unit?

Fan coil units are standalone systems that circulate the existing air in a space. They can also be part of a large HVAC system while air handling units (AHU) are a part of an HVAC system that cools and redistributes air into your home via ducts.

How much does it cost to replace a fan coil unit?

You’ll assume the cost of the new fan coil unit along with the installation costs. A new fan coil unit may range from $200-$1500 based on the brand of your unit and the size of the equipment. Professional installation, which is recommended for best results, will range from $700-$2700 depending on your region’s average pricing. Regular maintenance is required to ensure your fan coil unit is working efficiently for as long as possible before you’ll need to replace the unit.

Do fan coil units use refrigerants?

Yes, fan coil units use refrigerant to cool or heat the air in a room. Refrigerant is placed inside the indoor coil of an FCU and when the fan is turned on, it forces air through this coil which either heats or cools it depending on the desired temperature. The cooled or heated air is then sent into the room to maintain a comfortable environment. It is important to note that all HVAC systems using refrigerants should be maintained regularly as leaking refrigerants can have serious environmental consequences.
