SYLVESTER ELECTRIC · WINTER BACKUP POWER
The best time to find a generator problem is before you need it. If your home has a standby generator, a few checks now can help you plan for winter outages with fewer surprises.
For homeowners in the Merrimack Valley and Southern New Hampshire, start with the condition of your equipment, the space around it and the work it has already done. A generator that ran through a previous outage may be due for attention even if it looks quiet today.
Start here: Review alerts, confirm the exercise schedule, keep airflow clear, check service records and plan your fuel supply.
1. Read the status before a storm arrives
Check the generator's status display or its monitoring app, if your system has one. Record the exact warning or error code and when you noticed it. Use the owner's manual to understand what the message means; colors and controls can vary by model.
Arrange service for unresolved alerts before severe weather. Repeatedly clearing a code does not establish that the underlying problem has been fixed. If maintenance has recently been performed, ask the technician to confirm the system is ready for automatic operation.
2. Know when the generator exercises
Find the scheduled exercise day and time in your owner's manual, controller or monitoring app. If you have not heard the expected run, or you received a missed-exercise notification, have the setting and equipment checked.
Keep a simple record of what you observed. An exercise run is one useful check; ask your service technician whether transfer operation and the loads your home depends on have also been checked. Do not open transfer equipment or shut off utility power yourself to simulate an outage.
3. Keep leaves, snow and stored items away
Look at the generator's surroundings before winter makes access difficult. Avoid storing bins, firewood or other items against the enclosure. Plan where shoveled or plowed snow will go so it does not pile up around the unit.
Generac's snow guidance calls for keeping snow clear for three feet around the generator to support airflow. Follow the requirements for your exact equipment. Snow clearance is separate from installation setbacks, which must follow the manufacturer's instructions and applicable requirements.
A standby generator's weather housing is designed for its operating conditions. Do not wrap a running unit in a tarp or build an improvised enclosure around it. Have a professional address persistent drifting or access problems without blocking intake or exhaust openings.
4. Review service history and cold-weather needs
Find the last service date, current run hours and the maintenance schedule for your model. Maintenance can be due by elapsed time or operating hours. A long outage can bring the next service forward.
Ask a qualified service provider to review the starting battery, charging system, oil and filters, and any model-specific maintenance items. Have them explain what you should monitor during an extended outage and how to arrange any required service safely. Never add oil to a running engine.
Cold-weather accessories depend on the generator and battery type. Ask whether the manufacturer recommends a compatible battery warmer, oil warmer or other equipment for your particular system and conditions. Do not assume every generator needs the same kit.
5. Make a fuel plan before roads get difficult
If your generator uses propane, review the tank level and delivery arrangements with your supplier. Heating and generator use may draw from the same tank. Tell the supplier about your generator and ask how cold weather, tank capacity and expected demand affect your refill plan.
There is no universal propane level or outdoor temperature that guarantees reliable operation for every installation. Never try to correct a pressure issue by heating a propane tank. For natural gas, ask the appropriate service provider about any fuel-delivery concern rather than assuming a generator fault is electrical.
6. Keep the household plan ready too
Make sure everyone knows where to find flashlights, charged power banks, the generator manual and service contact information. If you will be away, arrange a safe way for someone to notice alerts or accumulating snow. Avoid relying on an app as your only outage plan.
Check your carbon monoxide alarms according to their instructions, including battery backup and replacement dates. If a CO alarm sounds, leave the home and call 911 from outside. Our smoke and carbon monoxide alarm services can help with installation and replacement needs.
Using a portable generator instead?
Portable generators have different setup rules. CPSC says to operate them outdoors at least 20 feet from the home, with exhaust directed away from buildings. Never run one in a garage, even with the door open, and never connect one to a household wall outlet. Have an electrician assess any connection to home wiring.
7. Revisit your plan when the home changes
Have you added an EV charger, heat pump, electric water heater or another major load since the generator was installed? Make a list before your next appointment. The equipment you want backed up, its starting demand and any load-management controls affect the plan.
A larger electrical service does not automatically mean a larger generator is needed. Start with what you want powered and have the system assessed. Learn about standby generator installation or electrical panel replacement if you are planning changes.
Questions homeowners often ask
Can a standby generator run all winter without attention?
Follow your model's operating and maintenance instructions. Extended operation still requires monitoring and maintenance at the specified intervals. Arrange that plan before an outage.
Should I cover my standby generator during a snowstorm?
Do not place a tarp or secondary enclosure around an operating standby generator. Keep the manufacturer's required airflow and exhaust areas clear, and ask a service professional about persistent snow drifting.
What should I have ready when I call?
Have the make and model, alert message, last service date, run hours if available and a short description of the issue. If you are planning a new installation, list the equipment you want backed up and whether your home has natural gas or propane.
