The most expensive maintenance event in any commercial building is the one that wasn't scheduled. HVAC failures in peak summer, generator starts that fail during power outages, and elevator shutdowns during peak occupancy are rarely random — they're the predictable outcome of a preventive maintenance calendar that either doesn't exist or exists only on paper. OxMaint gives facility teams a centralized PM calendar that schedules, assigns, and tracks every recurring maintenance task across every critical building system — so your assets never miss a service interval again.

PM Schedule by Facility Asset Type
| Asset System | PM Tasks | Frequency | Downtime Risk if Missed | OxMaint Trigger |
|---|---|---|---|---|
| HVAC — Air Handling Units | Filter change, belt inspection, coil cleaning, drain pan check | Monthly / Quarterly | Critical — cooling failure | Time-based calendar |
| Emergency Generator | Load test, fuel check, battery test, oil change, coolant level | Monthly / Annual | Critical — power failure | Runtime + calendar |
| Elevators / Lifts | Safety brake test, oil levels, door operation, governor test | Quarterly / Annual | High — outage and liability | Regulatory calendar |
| Chilled Water Pumps | Bearing lubrication, seal inspection, vibration check, alignment | Quarterly / Semi-annual | High — cooling failure | Runtime hours |
| Fire Suppression System | Sprinkler head inspection, flow test, valve check, pump test | Quarterly / Annual | Critical — compliance failure | Regulatory calendar |
| Electrical Switchgear | Thermal imaging, torque checks, breaker testing, arc flash review | Annual | High — unplanned outage | Annual calendar |
| Plumbing — Backflow Preventers | Annual test, valve function, certification filing | Annual | High — code violation | Regulatory calendar |
How OxMaint Runs Your PM Calendar
01
Build Your Asset Register
Add every critical asset — HVAC, generators, pumps, lifts — with location, manufacturer, model, and service history. OxMaint becomes the single source of truth for your facility's equipment inventory.
02
Set PM Intervals
Define recurring maintenance tasks by calendar date, runtime hours, or regulatory trigger. OxMaint auto-generates work orders on schedule — no manual planning required after initial setup.
03
Assign and Dispatch
Work orders are assigned to the right technician or contractor automatically, with task instructions, asset history, and required parts attached. Field teams work from their mobile device — no paper forms.
04
Track and Close
Completed PMs are logged with technician sign-off, time spent, materials used, and any defects found. PM completion rates and overdue tasks are visible on the facility manager dashboard in real time.

EXPERT REVIEW
Gerald Tatum, PE, CFM
Professional Engineer, Certified Facility Manager — 26 Years Corporate Real Estate & Facilities Operations
"In every facility portfolio I've managed, the correlation between PM compliance rate and emergency work order volume is near-perfect. Buildings where more than 90% of scheduled PMs are completed on time have emergency repair rates roughly 60% lower than those running below 70% PM completion. The challenge for most facilities teams isn't knowing what to maintain — it's the operational discipline to execute on schedule. A digital PM calendar that auto-generates, assigns, and escalates overdue tasks removes the human bottleneck in that execution chain."
Stop Scheduling Maintenance in Spreadsheets
OxMaint auto-generates every PM work order, assigns the right technician, and escalates overdue tasks — so your calendar actually runs itself.
Frequently Asked Questions
Can OxMaint schedule PMs based on runtime hours rather than calendar dates for critical equipment?
Yes. OxMaint supports meter-based PM triggers for assets like generators, pumps, and compressors — where service intervals are defined by runtime hours rather than fixed dates. Connect your building management system or manually update meter readings in OxMaint, and the platform generates PM work orders automatically when the threshold is reached. This prevents both premature servicing and missed intervals caused by uneven asset utilization. Sign up free to configure meter-based PM schedules.
How does OxMaint handle PM scheduling for seasonally critical equipment like HVAC and chillers?
OxMaint supports seasonal PM schedules — for example, a chiller pre-season service automatically generates in April each year, and heating system checks trigger in September. Seasonal tasks can be set as fixed-date annual recurring or as seasonal window triggers. Facility managers can view the full 12-month PM calendar by system or by technician to plan workload and avoid scheduling conflicts during peak maintenance periods.

Can OxMaint generate the PM documentation required for equipment warranties and service contracts?
OxMaint's PM completion records include technician name, completion date, task checklist results, parts installed, and any defects noted — providing the documented service history that most equipment manufacturers require to maintain warranty coverage. For assets under service contracts, OxMaint tracks contractor PM completion and generates reports that match service contract audit requirements, giving you evidence that contracted services were performed on the agreed schedule.
What happens when a scheduled PM is deferred because of an active tenant event or building access restriction?
OxMaint allows facility managers to defer a scheduled PM work order with a reason code and rescheduled date — the deferral is logged in the asset's history, and the rescheduled task appears in the next available calendar window. Deferred tasks remain visible on the manager dashboard with their deferral reason until completed, preventing the common scenario where a deferred PM is simply forgotten and never rescheduled. Deferral frequency by asset is also reportable — useful for identifying scheduling conflicts that warrant a PM calendar restructure.
