Winter Generator Checklist for Building Caretakers and Homeowners

Cold weather increases the demand on standby generator systems. A structured inspection routine helps identify issues before they become failures. Whether you manage a commercial facility or maintain a residential backup system, consistency is key.

Below is a practical winter checklist to support reliable operation.

Weekly Inspection Checklist

1. Visual Inspection

Conduct a thorough visual check of the generator and surrounding area.

• Look for oil, coolant, or other fluids on the floor or inside the enclosure
• Check the engine controller for red or flashing warning lights
  • Flashing red lights typically indicate a shutdown or fault condition
• Confirm the automatic transfer switch is in automatic mode

A system left out of automatic will not respond during a power outage.

2. Smell Test

Unusual or foul odors can indicate overheating, fluid leaks, or electrical issues. Any abnormal smell should be investigated immediately.

3. Fluid and Battery Check

• Verify engine oil levels
• Check coolant levels
• Inspect batteries for corrosion, loose connections, or swelling

Battery corrosion can reduce conductivity and lead to failed starts in cold weather. Clean terminals and secure connections are essential.

Monthly Inspection and Exercise

Regular exercise keeps internal components lubricated and ensures the system is capable of carrying load.

Run and Test the Generator

• Homeowners: Run the generator for a minimum of 30 minutes
• Commercial and life safety units: Run for a minimum of 1 hour

The one-hour minimum for commercial and life safety systems aligns with **CSA Group Standard C282 recommendations for emergency power systems.

During testing:

• Confirm the unit transfers properly
• Verify all indicator lights return to green status
• Ensure elevator systems and connected life safety equipment operate correctly where applicable

After testing, confirm the system and transfer switch are returned to automatic mode.

Documentation Matters

For commercial facilities, every monthly run-up should be documented in the generator logbook provided by Power-West Industries. Accurate documentation supports compliance, simplifies inspections, and provides a service history that can reduce liability.

Preventative Oversight

Winter conditions are predictable. Generator failure is preventable.

Weekly inspections combined with documented monthly exercise cycles significantly reduce the risk of unexpected downtime. For facilities with critical operations, these checks should complement a formal preventative maintenance program conducted by qualified technicians.

If you are unsure whether your system is being exercised correctly or documented to current standards, Power-West can review your maintenance routine and ensure your generator remains ready to perform when required.
