Fan Coil Unit Not Heating

Fan coil and heat pump units.

Fan coil unit not heating.

The device consists of a set of heating and or cooling coils and a fan to blow air over them. Fan coil units incorporate a chilled water coil for cooling and either a hot water coil for heating or an electric heating element. Fan coil units can be celling wall or floor mounted and there are both vertical and horizontal fan coil units. This air either heats or cools the room the unit is in.

You will want to open the case and start testing the circuits with the voltage regulator. If the electric heater fan comes on and you are not getting heat it could be a blown circuit or resistor or a broken heater coil. In buildings such as hotels where there is a need for temperature control in individual zones a split system is used that consists of an exterior condensing unit and cooling system and an interior fan coil or heat pump unit located near the conditioned space. As was the case with evaporator coil issues a condensing unit might have an excessively dirty coil or refrigerant leakage.

The thermostat controls the fan speed and or the throughput of. A fan coil unit is part of an hvac unit and is commonly used for residential applications. Condensing unit not turning on at all. Temperature control is usually achieved by using either an automatic thermostat or a manual on off switch.

Poor fan coil unit maintenance can increase operating costs by as much 25. Look for breaks in the electrical path and know voltages will change between circuits that are separated by resistors. Additional issues with the outdoor condensing unit might include a faulty compressor a failing condenser fan motor or a faulty run capacitor.
