Installing a Fan Coil Unit (FCU) in a chilled water fan coil unit system requires careful planning and attention to detail. Whether you're working with a hydronic fan coil unit, concealed fan, or FCU air conditioning, proper installation ensures long-term efficiency and reliable performance. This guide outlines the key steps involved in installing a fan coil unit HVAC system.

A fan coil unit (FCU) is a compact HVAC device that provides heating, cooling, and dehumidification by circulating temperature-controlled water. Proper selection involves estimating thermal loads, reserving 20–30% extra capacity for extreme conditions and usage variations, and choosing an installation type suited to the space. This ensures efficient, reliable performance in residential or commercial settings.

In today's HVAC industry, one of the growing concerns is the global shortage and rising cost of refrigerants. Traditional cooling systems rely heavily on refrigerants, making them vulnerable to supply chain issues and environmental regulations. As a result, the fan coil unit (FCU), especially those based on water systems, is emerging as a future-proof and sustainable solution.

In modern green building design, HVAC systems must meet higher standards of efficiency and sustainability. The fan coil unit is becoming one of the most popular choices. Among them, the YESNCER 4-Way Cassette Fan Coil Unit offers outstanding cooling and heating performance while using a water-based HVAC system—meaning it requires no refrigerant and delivers true environmental benefits.

Ceiling-mounted, water-cooled fan coils and concealed units designed for large-scale projects, providing cost savings and long-term collaboration opportunities.

Learn how to wire a fan coil unit switch the right way.** This guide explains standard wiring methods for both LCD panels and three-speed rotary switches, using YESNCER fan coil units as an example. Avoid costly damage by following the correct connection steps and understanding key wiring points.

DC brushless motors (BLDC) are transforming fan coil units. They play a key role in reducing energy consumption, lowering noise levels, and extending system longevity. While traditional AC motors are still widely used

Installing a horizontal concealed fan coil unit (FCU) involves more than placing a box above the ceiling. You need to optimize airflow, ensure efficient drainage, and maintain service access.
