Seasonal Generator Maintenance: What To Do As the Seasons Change
Routine maintenance is critical, but seasonal check-lists will keep your backup power system ready for whatever nature throws at it. From freezing winters to storm-prone summers in the Hamilton & Halton region, knowing what to inspect each season ensures your generator runs when you need it most.
At Remarkable Generators, we recommend the following seasonal maintenance schedule for homeowners and businesses alike to keep backup systems lasting longer and working reliably.
Spring & Summer Maintenance Checklist
– Clear vegetation, debris or snowmelt around the unit’s enclosure or pad; ensure ventilation is not blocked.
– Inspect the exhaust system for rust or corrosion—warm weather and humidity accelerate wear.
– Check coolant levels and hoses, especially if your generator runs on natural gas and has been idle over winter.
– Run the unit under load (for about 20-30 minutes) to ensure that surge loads (like AC or pumps) will be handled.
– Confirm fuel supply and tank vents (for propane/diesel systems) are clear and not affected by heavy rains or flooding.
Fall & Winter Maintenance Checklist
– Inspect the battery and charging system—cold temperatures reduce battery capacity significantly.
– Test automatic transfer switch (ATS) functions; ensure wiring remains solid and connections haven’t loosened.
– Drain or treat stored fuel (for diesel/propane) to avoid gumming, especially if the system sat idle during summer.
– Confirm that any enclosure heaters, drain pans or freeze-protection devices are operational.
– Ensure snow and ice will not block air intake or exhaust outlets; trim back shrubbery and clear space around the unit.
Frequently Asked Question
Q: How often should I schedule professional service instead of doing it myself?
A: Although you can handle many visual and basic checks, we recommend having a certified technician inspect your generator at least **once per year**, and additionally after major seasons (e.g., before winter or right after storm-season). Professional service includes load-bank testing, full electrical diagnostics and fuel-system inspection — tasks not typically covered in DIY maintenance.
Branded Tip: Keep a seasonal maintenance log (spring, summer, fall, winter) and make a checklist reminder for each change of season. When your service technician arrives, you’ll already have noted the recent checks and they can zero in on potential issues faster.
