Ceiling Fan Coil Unit Expert Buying Guide and Price List

Ceiling fan coil units offer the widest range in terms of appearance, capacity, and build quality, including noise level and air volume output.
Ceiling-mounted fan coil units are available in several configurations. All of these units—except for the concealed (built-in) type—are categorized as ceiling fan coils because they are installed above the false ceiling of building spaces.

The main types of ceiling fan coil units include concealed ceiling fan coils (with bottom air intake or rear air intake), exposed ceiling-mounted units, units equipped with a plenum filter, and units without a plenum filter. These fan coil units are widely used in building projects and are available with airflow capacities ranging from 200 to 1200 CFM, depending on the specific ceiling fan coil type.
Meanwhile, ceiling cassette fan coil units are classified separately due to their broader variety and structural differences compared to other ceiling-mounted fan coil units.

Ceiling Fan Coil Unit Components

Generally, ceiling fan coils have similar components and functions. The main components of a ceiling fan coil include a water coil, fan, electric motor, drain tray, filter, air vent valve, and other connections and equipment that are placed inside a galvanized sheet metal body.

In this system, air passes through the copper coil containing cold water in the summer and the coil containing hot water in the winter, providing cool and warm air in different seasons.

It is worth mentioning that the water flowing in these fan coils is cooled by central chiller systems or mini chillers in the summer and heated by the combi boilers or hot water boilers in the winter.

How a Ceiling Fan Coil Unit Works

The operating principle of a ceiling fan coil unit is similar to that of other types of fan coil units. In this process, air is drawn and circulated by the rotation of the unit’s internal fan, passing through a copper coil containing chilled water in summer and a coil containing hot water in winter. As a result, the air temperature is decreased or increased, and the conditioned air is then delivered into the indoor space through the air outlets. In this way, both cooling and heating are provided during different seasons of the year.
This process is continuously repeated until the room temperature reaches the set value, creating a uniform and comfortable thermal condition. It should be noted that the circulating water in these fan coil units is cooled in summer by central systems such as chillers or mini chillers, and heated in winter by a boiler in the mechanical room or by a package unit.

Types of Ceiling Fan Coils

Ceiling fan coil units differ from each other in terms of appearance, installation position, and pressure tolerance, and they create the following categories:

1. Concealed Ceiling Fan Coil Unit

The concealed ceiling fan coil, either with or without a cabinet, is the best-selling type of ceiling fan coil, produced and offered by many manufacturers such as Tahvieh, Sarmā Afarin, Yekta Tahvieh Arvand, Saran, Saraval, DamaTajhiz, Green, etc.

This type of fan coil unit is installed within the false ceiling, with only the air outlet grilles visible and exposed in the ceiling; for this reason, concealed ceiling fan coils are considered one of the most commonly used options in interior design.

Concealed ceiling fan coils are available in airflow capacities ranging from 200 to 1200 CFM to meet the cooling and heating needs of buildings of various sizes, and they are mostly suitable for residential, office, commercial, and hotel projects.

Since this model is installed within the false ceiling, its noise level is lower compared to surface-mounted ceiling models; however, maintenance and repair require better access due to its placement inside the ceiling.

Concealed ceiling fan coils have two models based on how they receive air: rear suction and bottom suction. The main difference between these two models lies in the location of the return air entry into the fan coil, which affects the device's performance, installation method, and space conditions.

1.1. Concealed Ceiling Fan Coil Unit—Rear Suction

In this model, the ambient air is drawn in through a grille located at the back of the fan coil, and after passing through the filter and cooling or heating coils, it is blown into the environment.

Rear suction fan coils are typically used when there is enough space behind the unit to provide return air from the environment. The features of the concealed ceiling fan coil with rear suction include:

Higher efficiency due to more uniform air entry into the device. Suitable for spaces where there is enough room behind the false ceiling for air suction. It has a relatively quieter operation compared to bottom suction models, as the return air enters the fan through a more direct path. The possibility of using various filters to improve the quality of incoming air.

1.2. Concealed Ceiling Fan Coil Unit—Bottom Suction

In this model, air is drawn in from the bottom of the fan coil, and after passing through the filter and coils, it is distributed through outlet grilles in the environment.

Bottom suction fan coils are designed for spaces where it is not possible to provide return air from the back, such as low ceilings or places where the space behind the unit is blocked. The features of the concealed ceiling fan coil with bottom suction include:

Suitable for spaces where the height of the false ceiling is limited and air suction from the back is not possible. Easier installation and repair compared to the rear suction model, as the filters and components of the device are accessible from below.

An ideal option for places that require faster air circulation. It may have a higher noise level compared to the rear suction model, as air enters the device directly from the bottom.

2. Exposed Ceiling Fan Coil Unit

Today, exposed ceiling fan coil units are less popular among manufacturers and consumers than other types of fan coil units.

An exposed or surface-mounted ceiling fan coil unit, which is also known as a fan coil with a cabin, is designed for surface installation.

It should be noted that some manufacturers, such as Green, introduce this type of fan coil unit to the market with the ability to install on the ceiling and the floor, under the name ceiling-floor fan coil. They are produced and supplied in various ventilation capacities to meet different needs.

3. Ceiling-Floor Fan Coil Unit

The ceiling-floor fan coil unit is one of the most flexible types of fan coil units, as it can be installed either horizontally beneath the ceiling or vertically on the floor. Due to its specific body design, this unit allows installation in spaces with installation constraints, making it a suitable option for locations where installing a concealed ceiling fan coil unit or a conventional floor-mounted fan coil unit is not possible.

The ceiling-floor fan coil unit is typically equipped with a metal cabinet, a washable air filter, adjustable air discharge louvers, and a variable-speed fan. This model is usually manufactured in a wide range of capacities, approximately from 400 to 1000 CFM, and thanks to its flexible installation options, it is well suited for residential units, office spaces, retail areas, hospitals, and especially renovation projects; in other words, any location where there is either insufficient space for installing a floor-mounted fan coil unit or no false ceiling available for installing a concealed fan coil unit.
The use of ceiling-floor fan coil units in Iran is less common compared to concealed or cassette models; however, in situations involving spatial or architectural limitations—particularly in buildings with low ceiling heights or walls fully occupied by windows—this type is recognized as a smart and practical solution.

Surface-Mounted Ceiling Fan Coil (With Cabinet) vs. Ceiling-Floor Fan Coil

The main difference between these two types of fan coil units lies in their installation method, body design, and level of flexibility in installation positioning. A surface-mounted ceiling fan coil unit is installed only horizontally beneath the ceiling and features an external cabinet, making it suitable for spaces without a false ceiling. In contrast, a ceiling-floor fan coil unit is designed to be installed either horizontally on the ceiling or vertically on the floor. These models are usually supplied with a cabinet equipped with adjustable support legs or a dual-orientation body design, and they are considered a more practical option for projects with architectural constraints. The table below provides a summarized comparison of these two models:

Features	Surface-Mounted Ceiling	Ceiling-Floor
Installation Method	Horizontal installation only beneath the ceiling	Horizontal on the ceiling or vertical on the floor
Need for False Ceiling	Not required	Not required
Recommended Application	Spaces without a false ceiling and with high ceiling height	Spaces with installation limitations
Mounting Base	Not available	Usually equipped with adjustable support legs
Market Prevalence	Relatively common	Less common but practical

4. Cassette Ceiling Fan Coil Unit

The cassette ceiling fan coil unit is one of the most commonly used types of ceiling fan coils, produced and offered in capacities ranging from 300 to 1,500 CFM with its unique design compared to other ceiling fan coils.

Cassette ceiling fan coil units are installed recessed in the false ceiling, with only their visible panel being noticeable; for this reason, they occupy less space and have a desirable appearance. Installing a cassette fan coil system, in addition to the false ceiling suitable for placing the unit, also requires the provision of water and electrical piping.

This model of ceiling fan coil unit is usually considered an ideal option for spaces where appearance is critical, such as offices, hotels, stores, and commercial buildings, due to their uniform air distribution in the environment.

In fact, it can be said that cassette fan coil units are used in places that require a combination of high efficiency with a more suitable appearance.

Other features of the cassette fan coil include the presence of a drain pump for discharging condensed water, which prevents water from accumulating inside the unit.

Additionally, one of the main advantages of this fan coil is its quiet operation and optimal air distribution; however, its installation cost is typically higher than that of other ceiling fan coil models and requires a suitable false ceiling. Cassette FCUs are categorized into three types based on the number of airflow directions:

4.1. One-Way Cassette Ceiling Fan Coil Unit

The one-way cassette fan coil directs air from only one side into the space and is mostly used in areas where a specific direction for air distribution is sufficient (such as next to walls, small offices, conference rooms, or small stores).

4.2. Two-Way Cassette Ceiling Fan Coil Unit

The two-way model of the ceiling cassette fan coil directs air from two opposite directions into the space and is usually used in rectangular areas or long corridors that require balanced air distribution.

4.3. Four-Way Cassette Ceiling Fan Coil Unit

The four-way cassette fan coil is one of the most commonly used cassette models that distributes comfortable air from four different directions in the space.

This model, with its uniform air distribution, increases ventilation efficiency and creates a consistent temperature in the environment.
