Fan Coil Units

Introduction to Fan Coil Units

How it works? 

A fan coil unit is a heating and cooling system that uses a fan to circulate conditioned air through ductwork or directly into a room. The system consists of a fan, an evaporator coil or heating coil, and a filter. The fan pulls air through the filter and over the coil, where it is heated or cooled, before being distributed back into the space.

Who first invented this unit? 

Fan coil units have been in use since the early 20th century, but no specific inventor can be credited with their creation.

Major producers and brands for this unit? 

Some major producers and brands of fan coil units include Carrier, Trane, Lennox, Rheem, York, and Goodman.

Major preventive and corrective maintenance activities done on this unit 

Some major preventive and corrective maintenance activities for fan coil units include cleaning or replacing the air filter, cleaning the evaporator or heating coil, checking refrigerant levels (if applicable), inspecting electrical connections and controls, and lubricating moving parts.


The cost of a fan coil unit can vary widely depending on factors such as brand, capacity, and features. Generally, prices range from a few hundred dollars for a basic model to several thousand dollars for a high-end model with advanced features.

Capacities range 

Fan coil units come in a variety of capacities, typically measured in tons. Capacities can range from around 0.5 tons for a small residential unit to over 10 tons for a large commercial unit.

Advantages and disadvantages 

Advantages of fan coil units include their versatility, ability to provide both heating and cooling, and relative affordability compared to some other systems. Disadvantages include their potential for noise and the need for regular maintenance to ensure proper operation and indoor air quality.

Where it is used mostly? 

Fan coil units are commonly used in smaller commercial buildings and residential buildings with individual room temperature control needs. They are also used in larger buildings with centralized HVAC systems to provide additional heating or cooling to specific areas or zones. Fan coil units can be a good option for retrofitting into existing buildings or spaces where ductwork installation may be difficult or impossible.
