2 lists · 7 items · 11 photosActive chilled beam maintenance checklists
Active chilled beam maintenance checklists for the quarterly and annual rounds: 2 free lists, 7 items and 11 photo requirements, each item naming what to look for and the photo that proves it. Work is commonly verified against IMC (mechanical code); the edition in force is the AHJ's call on each project.

Where each walk sits in the schedule
- Active chilled beam quarterly maintenance checklistquarterly
- Every quarter, because beams run dewpoint-close by design and a little coil fouling or a failed valve is what turns a tuned unit into a dripping ceiling. Run by: The HVAC or controls tech on the quarterly round, working from a lift or ceiling access.
- Active chilled beam annual maintenance checklistannual
- Once a year, timed with the seasonal changeover so the coil can be cleaned and the dewpoint interlock proven before the humid cooling season. Run by: The HVAC service lead on the annual service, coordinated with the controls contractor.
What most often fails on an active chilled beam
- Chilled-water valve stuck open or supply temperature running below the room dewpoint, so the coil sweats and stains the ceiling.
- Induction nozzles or the coil face fouled with lint and dust, cutting induced airflow and letting output collapse.
- Primary (conditioned) air off, throttled or undehumidified, removing the drying air the beam relies on to stay above dewpoint.
- Coil vacuumed lightly instead of cleaned through, so induced airflow and capacity never fully come back.
- Dewpoint or condensation interlock never exercised, and it fails to close the valve the first humid day the door stays open.
Verified against
Families only, never clause numbers. Adoption varies by jurisdiction; confirm the edition your authority having jurisdiction enforces before you run a walk against it.
Common questions
- Which active chilled beam maintenance rounds do these checklists cover?
- Active chilled beam quarterly maintenance checklist (quarterly): Every quarter, because beams run dewpoint-close by design and a little coil fouling or a failed valve is what turns a tuned unit into a dripping ceiling. Active chilled beam annual maintenance checklist (annual): Once a year, timed with the seasonal changeover so the coil can be cleaned and the dewpoint interlock proven before the humid cooling season.
- Who runs the active chilled beam maintenance round?
- The HVAC or controls tech on the quarterly round, working from a lift or ceiling access. The HVAC service lead on the annual service, coordinated with the controls contractor.

- Which standards is active chilled beam work verified against?
- IMC (mechanical code), published by the International Code Council. Adoption varies by jurisdiction. Confirm the edition your authority having jurisdiction enforces before you run a walk against it.
- Can I run these checklists in RTI?
- Yes. Start a free RTI workspace and load any of the 2 lists (7 items in total). The Photo Gate holds the submit button until every mandatory item is answered and its photos are attached, and approved inspections roll into a branded turnover package with a tamper-evident audit trail.
