Horizontal fan coil units is a type of fan coil installed on the wall or ceiling. Its installation method is relatively flexible and can be adjusted according to needs. Since the air inlets and outlets are distributed on two sides, maintenance and cleaning are relatively easier.

 However, compared with vertical fan coil units, the service life of horizontal fan coil units is relatively shorter because problems such as vibration, looseness, and failure are prone to occur due to gravity. The operating efficiency is also not as good as that of vertical fan coil units because there is a water pump inside, which requires additional energy consumption.

The efficiency of the unit also plays a role.

 From the perspectives of service life, operating efficiency, installation method, etc., vertical and horizontal fan coil units have their own advantages and disadvantages in different application scenarios.
 Although vertical fan coil units occupy a relatively small area and can provide stable performance and efficiency, they are difficult to maintain and clean. The fan coil unit is easier to repair and clean, but it is not as efficient as the vertical fan coil unit in terms of efficiency and service life.
 In general, when choosing between vertical fan coil units or horizontal fan coil units, you need to consider different site characteristics and personal needs. Through comprehensive comparison and evaluation, a more suitable model and a more ideal space solution can be selected.
