Professional Generator Maintenance for Reliable Backup Power
Generator Reliability Risks
Backup generators are built for critical situations—but when they fail to start during an outage, the consequences can include downtime, lost inventory, and operational disruption.
Routine maintenance helps identify issues early and ensures your system performs when it matters most.
Why “Exercising” Your Generator Is Not Enough
Many systems “exercise” for a few minutes each week, but running without load does not fully test performance.
Load bank testing verifies cooling, fuel delivery, and electrical output under real operating conditions—ensuring your generator can support full building demand during an outage.
CRG Electric prioritizes load bank testing to confirm your system is truly ready.

Generator Maintenance FAQs
How often should generator maintenance be performed?
Most generators should be serviced at least once per year, with additional inspections for high-use or critical systems. Regular maintenance helps ensure your system performs when it matters most.
What is load bank testing and why is it important?
Load bank testing applies a controlled electrical load to your generator to verify it can perform under real demand. This process helps identify performance issues that routine exercising does not detect.
What happens if my generator fails during an outage?
CRG Electric provides fast-response repair and emergency support to restore power quickly. Temporary rental generators may also be deployed if needed.
Do you service both residential and commercial generators?
Yes. CRG Electric provides maintenance, testing, and repair services for residential backup systems and commercial or industrial generators across Southeast Michigan.
