Commercial Generator Maintenance: What’s Required and How Often Should It Be Done?

Installing a commercial generator is a powerful step toward securing your business operations—but keeping that generator in peak condition is just as important. Too often, businesses invest in backup power systems only to neglect regular servicing, leaving their equipment vulnerable when it’s needed most. Proper commercial generator maintenance not only extends the life of your equipment but ensures your business stays protected during unexpected outages. Here’s what business owners need to know about servicing business generators and establishing a smart upkeep schedule.

Why Commercial Generator Maintenance Matters

Your generator is a mission-critical asset. It protects revenue, employee productivity, and customer trust by keeping essential systems online during power interruptions. But without consistent maintenance, even the best commercial generators can fail. Fuel degradation, battery corrosion, clogged filters, and unnoticed coolant leaks are just a few of the issues that can render your generator unreliable. A proactive generator upkeep schedule helps prevent costly repairs, downtime, and safety risks.

What’s Included in Commercial Generator Maintenance?

Professional commercial generator maintenance covers both mechanical inspection and operational testing. A typical service appointment from Commander Power Systems includes:

  • Oil and filter changes
  • Battery voltage and terminal checks
  • Fuel system inspection for leaks or degradation
  • Coolant level and temperature checks
  • Air filter replacement
  • Exhaust system inspection
  • Testing of automatic transfer switch (ATS)
  • Load bank testing (if applicable)
  • System diagnostics and software updates

Our technicians document every step, identify wear-and-tear concerns, and provide actionable recommendations to keep your generator ready at all times.

How Often Should Commercial Generators Be Serviced?

While every generator and use case is different, most commercial generator maintenance schedules follow these guidelines:

  • Weekly or Biweekly: Visual inspection and automatic test run to ensure system readiness
  • Monthly: Battery inspection, fluid checks, and status monitoring
  • Quarterly: Full inspection, functional testing, and cleaning
  • Semi-Annually: Fluid analysis, load testing, and electrical system diagnostics
  • Annually: Comprehensive service including oil/filter changes, replacement of wear components, and performance benchmarking

Businesses with critical infrastructure—such as healthcare facilities, data centers, or 24/7 operations—should consider more frequent service to comply with industry standards and reduce risk.

Signs Your Generator Needs Immediate Attention

Beyond your regular service schedule, it’s important to recognize red flags that could signal an urgent maintenance need. These include:

  • Visible fuel or oil leaks
  • Difficulty starting or failure to run automatic self-tests
  • Low battery voltage or charging failure
  • Smoke, vibration, or unusual noises during operation
  • Warning lights or fault codes on the control panel

If you notice any of these issues, schedule service immediately to avoid a surprise failure when you need backup power most.

The Cost of Neglect

Skipping generator maintenance doesn’t save money—it increases risk. Emergency repairs are often more expensive than preventive service, and the cost of business downtime can far outweigh the price of a maintenance plan. Investing in routine servicing ensures your generator performs reliably and extends the system’s lifespan by years.
