Preparing Your Generator for Winter: 2021 Checklist
Preparing Your Generator for Winter: 2021 Checklist

Winter is right around the corner. Or depending on when you’re reading this, it might already be here. And here in Massachusetts and the rest of the Northeast, that means threats of power outages from snow and ice storms. But there are a few key things you can do right now to stay prepared --- and keep your generator healthy so it’s ready when you need it. 

Annual or semi-annual maintenance by a pro is a great start, but there are some additional steps you can take to ensure reliability of your equipment and be prepared for the sleet, snow, freezing rain, and whatever else Mother Nature may send at you. Below are some preparedness tips from our experts for your emergency and standby power systems. 


Winter Maintenance Checklist

Repairs and Maintenance

  • Address any outstanding quotes for repair work from your generator service company (if applicable)
  • Complete any 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 needs replacement (Commercial generator batteries should be replaced every 3 years, while residential generator batteries should be replaced every 4 years

*If you have a residential preventative maintenance agreement with us, we’ll replace your battery every 4th preventative maintenance visit at no extra charge.

Generator Access

  • Keep your generator clear of weeds, trees and debris.
  • Your generator needs to breathe to stay cool, even in the wintertime. 
  • Removing obstructions will help to prevent 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 levers free and clear of snow.

Remote Monitoring

  • For ultimate peace of mind, consider setting up a 24/7 remote monitoring system for your generator.
  • There are systems for residential generators that can send you texts and alerts, and that email your service provider when your power is off, your generator is running, and when there is an alarm condition.
  • There are similar systems for commercial generators. These systems are more robust. They offer fuel level monitoring, remote start, and on newer units, remote diagnostics.


Maintenance will keep your equipment functioning properly but if something does go wrong, make sure you have a quality generator service company available 24/7 for emergency response.
