An HVAC failure during a sold-out sporting event does not just cause discomfort — it triggers early exits, social media complaints, and in extreme cases, evacuation. Meridian Sports Arena, a 22,000-seat multi-purpose venue hosting 140 events annually, deployed OxMaint CMMS to eliminate event-day HVAC failures through pre-event checklists, rapid-response work order workflows, and live equipment monitoring across its 48 air handling units. The result: zero HVAC-related event disruptions in 18 consecutive months.

22,000
Seated Capacity
Heat generated by 22,000 occupants requires precise ventilation load management — HVAC failure cascades within 20 minutes.

Revenue Per Sold-Out Event
A disrupted or evacuated event creates direct revenue loss, rebooking costs, and long-term reputational damage with promoters.
4 hrs
Pre-Event Setup Window
Technicians have a narrow pre-event window to verify, test, and resolve any HVAC issues before doors open to the public.
Before OxMaint: Reactive Response to an Unpredictable Schedule
Before OxMaint, Meridian's maintenance team relied on verbal handoffs between shift supervisors, a whiteboard work order system, and PDF checklists printed before each major event. PM scheduling for the 48 AHUs, 12 chillers, and 30+ exhaust fans was managed in a shared spreadsheet that had not been audited for accuracy in over 18 months. When HVAC faults occurred during events — as they did on three occasions in the prior season — the response time averaged 47 minutes because fault reporting followed a chain of radio calls before a work order was ever created.

In a live event venue, a 47-minute response to an HVAC fault is a guest experience failure. We had three of those in one season before OxMaint — each one cost us in refunds, in promoter relationships, and in the team's confidence that they could manage the building during high-pressure events. The pre-event checklist in OxMaint changed everything. We now go into every event knowing that every AHU, every chiller, and every exhaust zone has been physically verified and logged within the last four hours. That is the foundation everything else is built on.

Frequently Asked Questions
How does OxMaint handle HVAC maintenance across a venue with very different zone requirements for different events?
OxMaint allows venues to configure zone-specific HVAC settings and checklist templates that can be applied per event type. A hockey game with ice surface requirements demands different ventilation management than a concert or a trade show. Pre-event checklists in OxMaint can be templated by event category, pre-assigned to the relevant technician, and automatically scheduled based on the event calendar. When a new event is added to the schedule, OxMaint can generate the relevant pre-event checklist and PM verification tasks automatically — ensuring the right configuration is verified before every event, not just major ones.

Can OxMaint work orders be assigned to technicians in real time during a live event?
Yes. When an HVAC fault is detected — whether through a monitoring alert or a reported defect — OxMaint creates a work order and assigns it to the available technician with the relevant skill set based on a configurable dispatch rule. The technician receives the work order on their mobile device with asset location, fault description, relevant maintenance history, and a parts checklist based on the fault code. Assignment, acceptance, and completion are all timestamped automatically, creating a real-time view of response progress on the operations dashboard for the duty manager. Meridian Arena reduced its average event-day fault response from 47 minutes to 22 minutes using this workflow.

How does OxMaint help arena operations justify HVAC maintenance investment to venue ownership?
OxMaint produces maintenance cost per event reports, planned vs reactive ratio trends, and PM compliance histories that translate maintenance activity into operational and financial terms venue owners understand. The shift from 44% to 79% planned maintenance ratio at Meridian Arena translated to a $56,000 reduction in emergency maintenance spend in the first 18 months — a figure that appeared directly in the OxMaint analytics dashboard with supporting work order data. Venue ownership can see the before-and-after comparison in a single report, making the CMMS investment case clear without requiring technical interpretation.
