Preventive Maintenance Arizona

Scope depends on the systems in your contract. UPS PM: visual inspection, battery impedance testing, capacitor and fan assessment, filter cleaning, load transfer verification, written report. Generator PM: engine oil and coolant checks, cooling system inspection, starting system test, ATS exercise and documentation, fuel quality check, NFPA 110 records. DC power plant PM: rectifier efficiency check, battery float voltage and temperature logging, impedance testing, BDFB inspection, Telcordia GR-29-CORE documentation. Battery PM: impedance testing, inter-cell connector torque check, trending data logged against prior baseline.

NFPA 110 calls for annual UPS maintenance at minimum. In Arizona, we typically recommend semi-annual service for critical facilities — spring before summer heat peak, fall after monsoon season. Arizona's summer heat accelerates capacitor wear, shortens battery service life, and loads cooling systems harder than a standard annual schedule accounts for. For facilities with strict uptime requirements, quarterly battery impedance testing between annual visits gives early-warning data without a full PM visit each time.

Yes — priority 24/7 emergency response is included in every PM contract, not sold as a separate tier. PM clients receive priority dispatch when they call, ahead of non-contract service requests. A PM program is only as valuable as the emergency coverage behind it. We don't separate the two.

Every PM visit produces a written service report with readings, as-found condition, work performed, and recommendations. For compliance-specific facilities: NFPA 99 and NFPA 110 maintenance records for healthcare, Telcordia GR-29-CORE documentation for carrier and colocation DC plant work, and written ATS test records for generator compliance. Reports are formatted to support audits, joint commission surveys, and facility management documentation — not handwritten inspection forms.

Yes — the majority of our PM clients are facilities where we inherited the program from another contractor or from in-house staff. We start with a baseline assessment to document current system condition, then build the maintenance schedule from that baseline. We've taken over programs in every condition, including systems with years of deferred maintenance. We're not locked to any manufacturer, so we evaluate what you have objectively and recommend the realistic path forward.

Preventive maintenance is scheduled — you perform specific tasks at defined intervals regardless of current system condition. Predictive maintenance uses condition monitoring data (battery impedance trends, thermal imaging, oil analysis) to predict when a component is approaching failure and schedule replacement before it does. A well-structured critical power PM program uses both: scheduled tasks at defined intervals, with trending data collected at each visit to inform predictive decisions. Battery impedance trending is the clearest example — data from successive visits tells you whether replacement is 3 months away or 2 years away.

Generic PM schedules are built for average US conditions — they don't account for Arizona's 110°F+ summer peak, haboob dust events, or monsoon season moisture. We time battery service to catch degradation before summer heat pushes internal temperatures to their seasonal high. Generator coolant and cooling fan service goes in spring before the system works hardest. Filter audits happen after monsoon season — dust-packed intakes are a direct cause of thermal failures in Arizona facilities. These decisions come from knowing what actually fails here and when, not from a standard manufacturer guide.
