Prepare Your Generator for Winter

Winter is just around the corner! Follow our preparedness tips below to keep your generator healthy and ready to keep you on when the power goes off.

Each season presents its own challenges for your Emergency and Standby power systems. While we provide annual and semi-annual maintenance, there are additional steps you can take to ensure reliability of your equipment and be prepared for the coming season.

Winter Maintenance Checklist

Repairs and Maintenance

  • Address outstanding quotes for repair work
  • Complete necessary repairs to the cooling systems including coolant flushing and fresh antifreeze
  • Make sure block heaters are plugged in and functional


  • Make sure the diesel or propane fuel tank is full


  • Replace the battery if it is in need of replacement
  • Commercial generator batteries should be replaced every 3 years
  • Residential generator batteries should be replaced every 4 years
  • If you have an existing residential preventative maintenance agreement with FM Generator, the battery is replaced every 4th PM at no additional charge

Generator Access

  • Keep your generator clear of weeds, trees and debris
  • Your generator needs to breathe for stay cool, even in the wintertime!
  • Removing obstructions will help keep snow from collecting around the unit
  • When the snow does pile up, keep the generator shoveled out. Allow at least 2’ of clearance around the unit.
  • Protect your unit from snow plows that can pack snow in and around the generator
  • Never place a trap over the generator or build a cover or fence that is closer than 5 feet to the generator
  • Lubricate door locks to prevent them from freezing up
  • Indoor units that are ground level should have the inlet and outlet lovers free and clear of snow

Remote Monitoring

  • For ultimate peace of mind, consider the installation of a 24/7 remote monitoring system for the generator
  • We have systems for residential generators that sends you texts and provides FM Generator with an email alert when power is off, the generator is running, and when there is an alarm condition
  • We offer similar systems for commercial generators. These systems are more robust – they offer fuel level monitoring, remote start, and on newer units, remote diagnostics

CONTACT US to complete pending repairs or maintenance, or if you are interested in a remote generator monitoring program. Maintenance will keep your equipment functioning properly but if something does go wrong, we are available 24/7 for emergency response.
