Generator Maintenance Guide: Prepare for Ottawa Valley Ice Storms & Power Outages
If you have lived through an Ottawa Valley winter, you already know the power does not always stay on. Freezing rain coats the lines along the Madawaska and Ottawa rivers, a branch comes down somewhere between Arnprior and Renfrew, and suddenly the furnace, the well pump and the freezer all go quiet. A generator is one of the smartest investments a rural Valley homeowner can make -- but only if it actually starts when you need it. The hard truth most people learn the wrong way is that a generator left in the corner of the garage all year is far more likely to fail on the night you finally need it.
Good generator maintenance in the Ottawa Valley is not complicated, but it is seasonal and it is unforgiving of neglect. Here is the complete checklist we walk customers through every fall so they are not standing in the dark yanking a pull cord at 2 a.m.
Why Ottawa Valley Homes Need a Ready Generator
The Valley sits in a sweet spot for outages: long rural feeder lines, mature trees, and a climate that swings from summer thunderstorms to the kind of January ice events that take down poles. Towns like Braeside, White Lake, Pakenham, Calabogie and Kinburn often sit at the end of the line, which means restoration can take longer than it does in town. Add a private well -- no power means no water -- and a generator stops being a luxury and becomes part of your household safety plan.
But a generator is a small engine, and small engines hate sitting unused. Stale fuel, a dead battery and gummed-up carburetors are the three things that turn a perfectly good unit into an expensive paperweight. The fix is a little attention before the cold sets in.
Fall Maintenance Checklist: Oil, Air Filter, Spark Plug
Plan to service your generator in the fall, before the first real storm. Work through the basics in this order:
- Change the oil. Run the engine for a few minutes to warm the oil, then drain it and refill with the grade your manual specifies. For cold-weather starting, many manufacturers recommend a synthetic 5W-30. Fresh oil is cheap insurance; old, dirty oil thickens in the cold and makes hard starts worse.
- Inspect and clean the air filter. A clogged filter chokes the engine and causes rough running. Tap out a foam or paper element, or replace it if it is oil-soaked or torn. Briggs & Stratton units make this easy, and replacement elements are inexpensive.
- Check the spark plug. Pull it, look at the tip, and clean or replace it if it is fouled or worn. Set the gap to spec. A fresh plug is one of the most common reasons a stubborn generator suddenly fires on the first pull.
- Look over the recoil, fuel lines and connections. Cracked or hardened fuel lines are common on units that have sat a few seasons. Replace anything brittle now, not during a storm.
If you own a Briggs & Stratton generator, fall service is also a good time to have it looked at by an authorized dealer who stocks the right parts and knows the engine.
Fuel System Prep and Stabilizer
Stale gasoline is the number-one killer of standby generators. Modern pump gas in Ontario often contains ethanol, which absorbs moisture and starts to break down in as little as 30 days. That varnish clogs the tiny passages in the carburetor, and come storm season the engine either will not start or will not hold a steady speed.
Two habits solve almost all of it:
- Add fuel stabilizer to every tank you intend to store. Treat fresh gas with a quality stabilizer and run the engine for ten minutes so the treated fuel reaches the carburetor. Stabilized fuel can keep for many months.
- Decide between storing full or storing dry. A full, stabilized tank limits condensation inside the tank. Alternatively, run the carburetor dry by shutting off the fuel valve and letting the engine stall -- this is the better choice for units that sit for very long stretches. Pick one approach and stick with it.
Whatever you do, do not store last year's untreated gas and assume it will be fine. If you are not sure whether the fuel in your unit is still good, it is safer to drain it and start fresh.
Don't Skip the Battery: The #1 Winter Failure Point
For electric-start and standby generators, the battery is where most cold-weather failures actually happen. A battery loses a chunk of its cranking power as the temperature drops, so a battery that seems "okay" in October can be too weak to turn the engine over at minus 20.
Before winter:
- Test the battery with a load tester or have it tested. A surface voltage reading alone can be misleading -- a load test tells you whether it can actually crank.
- Keep it charged. A battery maintainer or trickle charger keeps a standby unit's battery topped up through the off-season. A flat battery that sits will sulfate and lose capacity permanently.
- Clean the terminals and check for corrosion, and make sure connections are tight.
- Replace aging batteries proactively. If your battery is several years old, swap it before winter rather than gambling on it during an ice storm.
Heads up, Ottawa Valley neighbours: if your generator only gets fired up during outages, treat the battery as a wear item. Don't get caught with a dead generator on the coldest night of the year -- we offer FREE pickup and delivery right in town, so a pre-winter service is painless.

Running Safely: Carbon Monoxide, Clearance and Load
A generator that starts is only useful if you run it safely. Carbon monoxide from a generator is invisible, odourless and deadly, and it kills people every winter who run units too close to the house.
- Never run a generator indoors, in a garage, or in a shed -- even with the door open. Place it well away from the house, ideally several metres out, with the exhaust pointed away from windows, doors and vents.
- Install battery-powered CO alarms in your home as a backup. They are cheap and they save lives.
- Keep it dry but ventilated. During freezing rain, use a proper open-sided generator tent or canopy designed for the purpose -- never a tarp draped over a running engine.
- Do not overload it. Add up the wattage of what you actually need -- furnace fan, well pump, fridge, a few lights -- and stay within the unit's rated continuous output. Motors like pumps and furnaces draw a big surge at startup, so leave headroom.
It is also worth doing a monthly test run under load through the storm season. Start the generator, let it run for 15 to 20 minutes with something plugged in, and confirm it holds steady. This exercises the engine, keeps the battery charged and tells you about a problem on your schedule instead of during an emergency.
The Dual-Fuel and Propane Cold-Weather Edge
Many newer portable generators are dual-fuel, running on either gasoline or propane. For Valley winters, propane has real advantages: it does not go stale, it will not gum up a carburetor, and a stored tank is ready whenever you are. That makes propane a great choice for a unit that sits most of the year.
The trade-off is cold starting. Propane vaporizes less readily in extreme cold, so a frigid morning start can be harder on propane than on gas. A common approach is to start and warm the engine on gasoline, then switch over to propane for the long haul. Keep propane tanks outside, check the hose and regulator for cracks each fall, and store at least one spare full tank.
When to Call a Pro
Plenty of generator maintenance is DIY-friendly, but some things belong with a qualified pro:
- Transfer switches and permanent wiring. Connecting a generator into your home's panel must be done with a proper transfer switch by a licensed electrician. Never backfeed a generator into a wall outlet -- it can electrocute a hydro worker and start a fire.
- Hard-starting, surging or smoking engines that fresh fuel, oil, a plug and a clean filter did not fix -- usually a carburetor or valve issue.
- Authorized Briggs & Stratton service. Warranty work and correct parts matter, and a dealer service keeps your engine running the way it was built to.
Your Pre-Storm Quick Checklist
When the forecast turns ugly, run through this fast:
- Fresh, stabilized fuel in the tank -- and a spare can or propane tank ready.
- Oil level checked and topped up.
- Battery charged and connections tight (test-crank it).
- Air filter and spark plug clean.
- A safe, dry, ventilated spot picked out, well away from the house.
- CO alarms working, extension cords and the transfer switch checked.
- A 15-minute test run completed in the last month.
A little fall maintenance is the difference between a generator that hums to life and one that lets you down when the Valley goes dark.
