Hotels often service chillers every 90 days, even when maintenance isn't needed. Condition-based PM uses real-time sensor data to trigger work orders only when equipment shows signs of failure. Since HVAC can account for 40–60% of hotel energy use
Oxmaint helps hotels, resorts and property groups run guest and housekeeping requests, work orders, preventive maintenance on PTACs, chillers and elevators, QR-tagged room assets, vendor coordination and fire & life-safety records — across every guestroom, F&B outlet and back-of-house area.

From guest request to closed work order before checkout — here's how Oxmaint manages engineering across every guestroom and outlet.
Register and QR-tag every asset, then connect your PMS and BMS.
Build occupancy-aware PM per asset class and set request routing by trade.
Guest requests and PM thresholds create WOs — engineer routed, PMS synced.
Track PM compliance, MTTR, out-of-order duration and cost per room.
AI Vision turns your existing back-of-house and public-area CCTV into a continuous inspection layer — flagging wet-floor hazards, kitchen spills, blocked fire exits, missing extinguishers and mechanical-room leaks between walk-throughs. Anything flagged becomes a prioritised work order with photo evidence attached to the asset record.
Kitchens, pool decks & lobbies
Blocked exits & missing extinguishers
Chiller, pump & riser water intrusion
Detection · WO · engineer assigned
Floor spill flagged · photo attached
Fire exit clear · No obstructions
Pump seal drip · logged to asset
Occupancy normal · No safety flags
Oxmaint connects to the BMS controllers, PTAC boards and IoT sensors already on your chillers, cooling towers and elevators, tracking cycling patterns, discharge temperatures and vibration against each unit's own baseline. When a reading drifts, a proactive work order is generated with parts reserved — turning a full-weekend chiller failure into a scheduled job in a quiet window.

Tag every guestroom door, PTAC, TV, safe and kitchen appliance with a QR label — one scan shows room number, warranty, last service, open WOs and full history. One tap creates a work order or runs a room turn inspection, with routing, parts reservation and room-status sync back to your PMS handled automatically. Works fully offline in stairwells and back-of-house dead zones.

Guest requests, work orders, PM schedules, room turns, kitchen assets, parts, vendor and COI records, life-safety compliance and PMS integration in one CMMS.
Front desk, in-room tablet and guest app requests become WOs with room and asset tagged — routed by urgency, duplicates merged.
Rooms move from dirty to inspected to ready-to-sell with photo-backed checks — out-of-order rooms return to inventory the moment WOs close.
Ovens, hoods, walk-ins, ice machines and dish machines tracked with runtime and temperature logs, generating HACCP-friendly records from every inspection.
PTAC filters, plumbing parts, remotes, key cards and bulbs across engineering and housekeeping — min-max levels and reorder alerts before stockout.
NFPA extinguisher, sprinkler, elevator and pool-safety schedules with photo-stamped logs — brand-standard and health-department records on demand.
Cost per room, MTTR, PM completion and request resolution time — trended per property, shift and engineer for month-end.
Vendor directory with live insurance expiry tracking, W-9 storage and rate cards — expired COIs block dispatch automatically.
Bidirectional sync with your PMS for room status and occupancy, building automation for equipment telemetry, and accounting for maintenance cost posting — no duplicate entry.
From guest complaint response to out-of-order room recovery and predictive PTAC replacement — three typical deployments.
The Problem
A 412-room full-service hotel took maintenance requests over radio and paper slips. Issues dropped through the cracks between shifts, and the front desk had no way to answer a guest asking about their own request.
What Oxmaint Did
Digital intake from front desk, in-room tablet and staff app replaced the radio traffic. Each request became a WO tagged to the room and asset, routed by urgency, with live status visible to the front desk.
Replacing radio & slips
By urgency & trade
Full-service hotel
Requests tagged by urgency and category, duplicates merged, each ticket pushed to an available engineer.
Engineers received WOs with room number, issue description and asset history pre-loaded, syncing back to the PMS on close.
Every status change — accepted, en route, resolved — visible to the front desk, so agents always had a live answer.
Response time and repeat-issue trends per room, shift and engineer surfaced bottleneck floors in the daily briefing.
The Problem
A 280-room resort held rooms out of order longer than the repair actually took — PTAC noise, minor leaks and remote batteries sat unnoticed for days. Housekeeping and engineering tracked status on separate spreadsheets, so nobody owned the release.
What Oxmaint Did
Housekeeping and engineering moved into one workflow. Every out-of-order room opened a linked WO with live status, and room status updated back to the PMS the moment the ticket closed — no separate release step.
Housekeeping & engineering
On work order close
Resort property
Every OOO room linked to a work order, with housekeeping and engineering on the same live status at shift change.
Room status pushed to the PMS the moment the WO closed, showing back in service the same day.
Attendants scanned a room QR at the door to run pre-arrival checks — any failed item auto-opened a work order.
Out-of-order duration and cost per room tracked as first-class KPIs, showing which assets drove the downtime.
The Problem
A 6-property resort group kept hitting PTAC and chiller failures on peak weekends. A chiller down on a full house meant an all-hands scramble, emergency contractor rates and rooms nobody could fix until Monday.
What Oxmaint Did
BMS controllers and PTAC boards were connected across all six properties, with runtime, cycling and service history per unit. Units drifting off baseline were flagged early and scheduled into low-occupancy windows.
Instead of emergency
Work booked around demand
Multi-property brand
Runtime, cycling frequency and discharge temperature tracked per PTAC, chiller and cooling tower to flag declining units.
Direct connection to building automation and unit boards across all six properties — no new hardware, PM on actual runtime.
Predictive work orders were booked into low-occupancy windows automatically — so PM stopped colliding with peak arrival days.
Replacement forecasts rolled up into a capex plan across all six resorts — a defensible line-item budget for owners.
Oxmaint connects with property management systems, building automation, kitchen controllers and accounting software — room status, telemetry and costs move both ways.
Explore All IntegrationsCameras in kitchens, corridors, mechanical rooms and pool decks flag wet-floor hazards, spills, blocked fire exits, missing extinguishers and leaks between scheduled walk-throughs. Anything flagged becomes a work order with photo evidence attached and the right engineer assigned.
Oxmaint connects to BMS controllers, PTAC boards and IoT sensors to monitor compressor cycling, discharge temperatures and refrigerant pressure against each unit's own baseline. When one drifts, it generates a proactive work order with parts reserved and books the job into a low-occupancy window.
Yes. Front desk, in-room tablets, staff app and guest app all feed one live queue. Each request becomes a work order with room, asset and trade tagged, routed by urgency to an available engineer — and the front desk sees live status without a radio call.
Yes. Engineers, room attendants and vendors scan QR codes, complete inspections, capture photos and log updates with no connectivity — designed for stairwells, mechanical rooms and sub-basements. Data syncs the moment signal returns. Available on iOS and Android.
Yes. Bidirectional sync with major hospitality PMS platforms, building automation and accounting. When a work order closes, room status updates in the PMS straight away — showing back in service the same day instead of waiting on a manual reconciliation.
Yes. Every inspection, PM task and compliance check is logged with photos, timestamps and engineer signatures. NFPA extinguisher and sprinkler inspections, elevator certifications, pool safety, HACCP kitchen logs and brand-standard walk-arounds pull per property, date range or asset class in seconds.
