Chilled Beam Maintenance Checklist
Keep chilled beams cooling quietly and condensation-free — coil cleaning, valve and dew-point control checks, induction nozzle inspection, and flow balancing.
What is a chilled beam maintenance checklist?
A chilled beam maintenance checklist is a structured list of the 10 preventive maintenance tasks — covering visual, functional, cleaning, safety and record-keeping checks — that keep a chilled beam 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 chilled beam checks
- Inspect for any signs of condensation, staining, or dripping
- Confirm chilled-water flow temperature stays above room dew point
- Inspect the coil for dust, lint, and fouling and clean as needed
- Check dew-point/condensation control and any condensation sensors work
- Record temperatures, dew-point checks, and cleaning in the log
What is a chilled beam?
A chilled beam provides quiet, draught-free cooling by passing chilled water through a coil at ceiling level. Passive beams rely on natural convection; active beams induce room air across the coil using primary air from the ventilation system through induction nozzles. The defining risk is condensation: if the chilled-water temperature falls below the room dew point, the beam sweats and drips. Systems therefore run relatively warm chilled water with dew-point control and humidity management. Maintenance keeps coils and nozzles clean, verifies valve and dew-point control, and confirms there is no condensation, because a dripping beam over an office is both a damage and a reputational problem.
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 Chilled Beam 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
- Inspect for any signs of condensation, staining, or dripping
- Check exposed pipework insulation and vapour sealing are intact
Functional Checks
- Confirm chilled-water flow temperature stays above room dew point
- Check control valves (often PICVs) modulate and fully close
- Verify primary air supply and balancing to active beams is correct
- Confirm room humidity is controlled within the design envelope
Cleaning & Housekeeping
- Inspect the coil for dust, lint, and fouling and clean as needed
- Clean induction nozzles (active beams) of dust affecting performance
Safety Checks
- Check dew-point/condensation control and any condensation sensors work
Record Keeping
- Record temperatures, dew-point checks, and cleaning in the log

Typical maintenance frequency
Suggested intervals for chilled beam maintenance. Actual frequencies should follow manufacturer guidance and site-specific risk assessments.
Quarterly
- •Check for condensation/staining
- •Verify flow temperature vs dew point
- •Spot-check valves and humidity
Annually
- •Clean coils and induction nozzles
- •Verify dew-point control and sensors
- •Check valves and balancing
- •Inspect insulation/vapour seal
