Chiller PM Scheduler
A free chiller maintenance register: last service, interval, due date and overdue alerts — sorted by urgency, stored in your browser.
Your register stays in this browser (localStorage) — nothing is uploaded.
Add your first chiller to see the schedule. Sorted by urgency, the next due item is always on top.
Field notes from maintenance practice
A chiller's health lives in its approach temperatures: condenser approach (condensing temp minus leaving water) rising over months means fouled tubes — log it monthly as part of the register's round and the annual tube-clean decision makes itself with data instead of habit. Oil and refrigerant analysis annually does for chillers what blood tests do for people: cheap, early, specific.
Refrigerant leak checks belong on the quarterly line (and may be legally mandated by charge size) — a slow leak both costs efficiency and can be an environmental compliance issue. Run the register on whatever device lives where the work happens — a workshop tablet beats a spreadsheet on someone's laptop, because the person doing the job sees the list.

About Chiller PM Scheduler
This scheduler keeps a living register of your chillers: add each one with its last service date and interval, and the board computes due dates, sorts by urgency and flags anything overdue or due within 14 days. One tap (✓) marks a service done and restarts that asset's clock. Chiller practice layers monthly operating-log rounds, quarterly checks and an annual major (tube cleaning/eddy current as needed, refrigerant analysis, controls calibration, vibration baseline).
How to use Chiller PM Scheduler
- 1Add each asset with its last service date and interval — presets reflect the cited standard, and you can override per asset.
- 2The register sorts itself by urgency: overdue first, then due-soon (≤14 days), with a badge per asset.
- 3Tick ✓ when a service is done to reset that asset's clock to today — the whole register persists in your browser.

Frequently asked questions
How often should a chiller be serviced or inspected?+
Chiller practice layers monthly operating-log rounds, quarterly checks and an annual major (tube cleaning/eddy current as needed, refrigerant analysis, controls calibration, vibration baseline). Severe duty, harsh environments or regulatory requirements shorten it — and your OEM manual, insurer or local code always takes precedence over the generic default.
Do my chiller tubes need brushing every year by default?+
Not by default — by approach temperature. Open condenser loops (cooling towers) foul fast and often justify annual brushing; closed loops may go years. A condenser approach creeping 2–3 K above its clean baseline costs roughly 6–10% in compressor energy and is your evidence-based trigger. Skipping data and brushing 'every spring' either wastes a service or misses a mid-season fouling event, depending on your water.
Some of my units work much harder than others — same interval for all?+
No — set per-asset intervals: this register stores an interval with each chiller, so the hard-worked unit can run a shorter clock than the spare. Halving the interval for severe duty (dust, heat, continuous running) is the standard rule of thumb, and the due list re-sorts automatically.
A service was missed by months — restart the clock or double up?+
Do the full service now and reset the clock from today (the ✓ button does exactly that). Don't 'average' missed intervals — inspect more thoroughly than usual instead, because the chiller just ran an unplanned extended interval and any developing problem had extra time to grow.
