Fan Coil Unit Servicing explained
Full fan coil unit servicing covering filters, coils, condensate, fan motors, valves and controls, with air-on/air-off readings recorded for every unit.
- Filter change and grille clean: Filter condition can restrict airflow; cleaning and replacement requirements depend on the filter specification.
- Coil fin comb and hygiene clean: Condition and airflow affect heat transfer; look beyond surface appearance to obstruction and operating performance.
- Condensate tray, trap and pump check: Confirm where condensate should discharge and whether the obstruction, pump or drainage arrangement is responsible.
- Fan motor, bearing and impeller inspection: Operation, mechanical condition and control demand must be separated before condemning the drive.
- Valve, actuator and PICV operation test: Check movement, control command and the effect on flow together; the actuator and valve body can fail independently.
- Air-on and air-off temperature readings: Confirm the component identity and model-specific requirements before deciding whether adjustment, testing or replacement is appropriate.
- Written service sheet per asset: Confirm the component identity and model-specific requirements before deciding whether adjustment, testing or replacement is appropriate.
Interpreting the reported fault
Check fan response, filter condition, valve operation, coil condition and condensate drainage. A working fan does not establish that the water coil is receiving the required flow.
- Reported symptom: weak airflow, dusty grilles and units that no longer hold set temperature
- Record when the problem started and any recent changes
- Keep fault codes and model details for the assessment
Maintenance is not a breakdown repair
A planned visit should establish condition and identify deterioration. An existing fault may need separate diagnosis and parts. Agree which assets, cleaning tasks, functional checks and records are included, and base the interval on manufacturer guidance and operating conditions.
- Provide the unit location, access-panel position, controller behaviour and whether neighbouring units show the same problem.
Labour and the work to be agreed
Engineer time is £120+VAT per hour with a one hour minimum. The time and materials required depend on the diagnosed fault and access. Ask for the repair scope, any additional parts and the return-to-service checks before proceeding.
- £120+VAT per hour, one hour minimum
- Confirm the parts and labour required for the specific fault
Fan Coil Unit Servicing across London
A fan coil transfers heat between room air and a water coil. The fan, control valve and building water supply all affect room output.
A fan, valve actuator or controller can often be assessed independently. Whole-unit replacement also requires access, coil duty, noise and connection compatibility to be considered.
Provide the unit location, access-panel position, controller behaviour and whether neighbouring units show the same problem.

Fan Coil Unit Servicing: scope, checks and next steps
Full fan coil unit servicing covering filters, coils, condensate, fan motors, valves and controls, with air-on/air-off readings recorded for every unit.
What the reported symptom tells us
weak airflow, dusty grilles and units that no longer hold set temperature. Record when this occurs, what changed beforehand and whether other equipment is affected. These observations narrow the investigation; they do not prove which part has failed.
A fan coil transfers heat between room air and a water coil. The fan, control valve and building water supply all affect room output.
Separate the possible causes
Check fan response, filter condition, valve operation, coil condition and condensate drainage. A working fan does not establish that the water coil is receiving the required flow.
Repair or replacement?
A fan, valve actuator or controller can often be assessed independently. Whole-unit replacement also requires access, coil duty, noise and connection compatibility to be considered.
Maintenance is not a breakdown repair
A planned visit should establish condition and identify deterioration. An existing fault may need separate diagnosis and parts. Agree which assets, cleaning tasks, functional checks and records are included, and base the interval on manufacturer guidance and operating conditions.
