Fan Coil Valve Maintenance Checklist
A maintenance checklist for fan coil unit valves covering actuator operation, valve seat inspection, flow verification, and BMS control signal testing — for HVAC zone temperature control.
Also available as editable Excel and Word — with asset, sign-off and findings columns.
What is a fan coil valve maintenance checklist?
A fan coil valve maintenance checklist is a structured list of the 9 preventive maintenance tasks — covering visual, functional, cleaning and record-keeping checks — that keep a fan coil valve running safely and reliably. It groups routine checks by frequency, from daily inspections to annual servicing, so FM teams and building engineers can plan and evidence preventive maintenance.
Core fan coil valve checks
- Check the actuator is firmly coupled to the valve stem
- Verify the valve opens and closes in response to the controller signal
- Clean the associated strainer if fitted
- Record valve condition, actuator operation, and any pass-by issues
What is a fan coil valve?
A fan coil valve is a small motorised valve that regulates hot or chilled water flow to a fan coil unit coil. These are typically 2-port or 3-port valves with low-torque actuators controlled by room thermostats or BMS zone controllers. Given the large number of FCUs in a typical commercial building, fan coil valves represent a significant maintenance workload and are one of the most common causes of occupant comfort complaints.
This checklist is one of 34 in our HVAC maintenance checklists, covering air handling units, fan coils, chillers, VRF, ductwork and extract systems — filters, coils, refrigerant and damper checks.
Typical Fan coil valve maintenance checklist
A practical starting point for planned preventive maintenance. Always refer to the manufacturer's O&M manual and site-specific requirements.

Visual Checks
- Check the actuator is firmly coupled to the valve stem
- Inspect valve body and connections for leaks
- Check the actuator cable routing is tidy and not damaged
Functional Checks
- Verify the valve opens and closes in response to the controller signal
- Confirm the valve achieves full shut-off (no pass-by when closed)
- Check the coil temperature difference (delta-T) to verify flow
- Verify the room controller or thermostat is operational
Cleaning & Housekeeping
- Clean the associated strainer if fitted
Record Keeping
- Record valve condition, actuator operation, and any pass-by issues

The PDF is free and needs nothing. The Excel and Word versions add asset details, sign-off and findings columns so you can record the work as you do it — we ask for an email address for those.
Typical maintenance frequency
Suggested intervals for fan coil valve maintenance. Actual frequencies should follow manufacturer guidance and site-specific risk assessments.
Quarterly
- •Spot-check actuator operation on a sample of FCU valves
- •Investigate any pass-by complaints from occupants
Annually
- •Check valve operation on all FCU valves
- •Test full stroke
- •Inspect for leaks
- •Clean strainers
- •Verify BMS signal response

Safety and compliance notes
Key safety considerations for fan coil valve maintenance. This is general guidance only — always follow OEM instructions, statutory requirements, and your organisation's safe systems of work.
Reference standards and frameworks
- United Kingdom
- SFG20 schedules and CIBSE Guide M
- North America
- ASHRAE/ACCA Standard 180 (HVAC inspection and maintenance)
- Middle East
- Dubai Municipality's Green Building Regulations require commissioning to CIBSE Commissioning Code A (air distribution), and cite ASHRAE 62 and 90.1
Frameworks commonly referenced when planning fan coil valve maintenance programmes. Always confirm the requirements that apply to your site and jurisdiction.
Managing Fan coil valve documentation with PM Assist
PM Assist helps FM and building operations teams search their O&M manuals and building drawings in seconds. Upload your fan coil valve documentation and ask questions like “What are the recommended service intervals?” or “Where are the isolation points?” — and get source-cited answers instantly.
The checklist tells you what to check. The manual tells you the numbers.
Ask a fan coil valve manual a question and get the answer back with the page it came from. No signup, and you can drop in your own PDF instead of the sample.
“What are the recommended service intervals?”Runs against a sample chiller manual so you can see the shape of the answer — then try it on one of yours.
