Fan coil unit (FCU) repair in Egypt — the terminal units in chilled-water central HVAC systems, widely used in hotel rooms, hospitals and offices. We service Carrier, Trane and York. Call **16062**.
An FCU consists of a copper coil, a small fan and a filter. Its efficiency depends on chilled-water flow and coil cleanliness. The common faults are condensate water leaks, fan motor failure and 3-way valve actuator failure.
The most frequent faults we encounter while servicing FCU — ranked by occurrence.
