24/7 Generator Preventative Maintenance, Load-Bank Testing & Repair
A standby generator that sits unserviced for two years is a failure waiting to happen during the next winter storm. Dead starting batteries, degraded diesel fuel, stuck transfer-switch contactors, and rodent-damaged wiring account for over 85% of emergency generator failures.
NYREER provides 24/7 preventative maintenance, diagnostics, and emergency repair for Kohler, Generac, Caterpillar (Cat), and other commercial and residential generators across NY, NJ, VT, and MA—even if we did not originally install your unit.
Comprehensive Preventative Maintenance (PM) Scope
- Lubrication & Filtration Service: Engine oil change, OEM oil/air/fuel filter replacement, crankcase breather inspection, and oil sample analysis for commercial diesel fleets.
- Cooling & Fuel System Integrity: Coolant freeze-point/inhibitor testing, block heater verification, belt/hose tensioning, natural gas/LP pressure manometer checks, and diesel fuel polishing / water-separator service.
- Starting & Charging Electrical Audit: Battery conductance load testing, float-charger calibration, starter current draw, alternator output, and brushless exciter inspection.
- Automatic Transfer Switch (ATS) & Live Transfer Test: Thermal imaging of main lugs, exercise timer verification, and supervised live load transfer simulation.
- Annual NFPA 110 Resistive Load-Bank Testing: Eliminates "wet stacking" on commercial diesel generators by running the unit under stepped 30% / 50% / 80% / 100% resistive load bank capacity and issuing a formal compliance report.
