A fan coil is an air handler that is used in heating, ventilation, and air conditioning (HVAC) systems. Fan coils consist of a coil of finned tubing, through which a heat transfer fluid circulates. A fan is used to force air over the coil, where it is either heated or cooled, depending on the application. You can buy a retrofit fan coil unit for more convenience.

Fan coils are typically used in applications where space is limited, such as in office buildings and hotels. They are also commonly used as retrofit units, since they can be easily installed in existing buildings without the need for significant ductwork modifications.
There are many different types of fan coils on the market, each designed for specific applications. For example, some fan coils are designed for use with chilled water systems, while others are designed for use with hot water systems. Selecting the right fan coil for your application is important to ensure optimal performance and energy efficiency.
When installing a fan coil unit, it is important to follow the manufacturer's instructions carefully. The unit must be properly sized for the space it will be used in, and all electrical and plumbing connections must be made correctly. The unit should also be level so that it operates correctly.
