There’s nothing quite like a power outage to remind you of all the things you take for granted like light, heat, and the ability to make coffee. That’s where a trusty backup generator comes in. But like any superhero, even your generator needs some TLC to stay in fighting shape. Welcome to Generator Maintenance 101 your no-fluff guide to keeping the lights on and your generator out of early retirement.
Whether you’re in the heart of Vancouver or up the Sea to Sky in Squamish, we’ve got expert tips, a few laughs, and all the generator maintenance wisdom you need to keep your power running.

Why Generator Maintenance Matters
Think of your generator like that old high school friend who only shows up when there’s a crisis but when they do, they better come through. Without regular generator maintenance, you’re risking an unreliable performance, higher repair bills, and potentially dangerous malfunctions. The importance of generator service cannot be overstated. We’ve seen it time and again at Expert Electric. One such instance involved a Kelowna homeowner who called us in mid-winter because their backup generator wouldn’t start. After a freezing night and a lot of frustration, we discovered it hadn’t been serviced in over two years. The fuel had degraded into a thick syrup-like consistency, clogging the system. Had regular maintenance been performed, this ordeal could have been entirely avoided.
The reality is that when the power goes out, your generator is expected to spring into action seamlessly. But without proper care, it might not even turn over. And when it fails, the consequences go beyond just inconvenience. You could be dealing with spoiled food, frozen pipes, loss of heat, or worse, depending on your location and needs. Maintaining your generator regularly not only ensures that it operates efficiently when needed but also prolongs its life and saves you from expensive generator repair. At Expert Electric, we emphasize preventative care because a little attention today can save a lot of headaches tomorrow.

The Basics of Generator Maintenance
Understanding the fundamentals of generator maintenance is essential for every homeowner relying on a backup generator. Start with the basics your owner’s manual. While it may seem tedious, the manual provides critical information tailored to your specific model. It details oil types, replacement intervals, maintenance schedules, and error codes. Skipping this step can lead to improper maintenance or missed steps that compromise your generator’s performance.
One of the most important routine tasks is checking and changing the oil. Just like your car, your generator needs clean oil to function properly. Dirty or old oil can lead to increased wear and tear on engine components, leading to reduced efficiency or complete failure. If you use your generator often, especially during prolonged power outages, check the oil every 50 to 60 hours of operation. At a minimum, aim to change it annually or after every 100 hours of use.
Air filters are another key component. A clogged air filter restricts airflow, forcing your generator to work harder and potentially causing it to overheat or shut down. Make it a habit to inspect your air filter regularly and clean or replace it as needed. This is particularly important if your generator is stored in dusty areas or used frequently.
Also, keep an eye on the spark plugs and fuel filters. These components tend to wear out over time and can affect performance. Replacing them according to manufacturer recommendations helps ensure reliable startup and smooth operation. Finally, run your generator periodically even if there is no outage. Monthly test runs help keep everything in working order and alert you to any issues before an emergency hits.

Seasonal Generator Service Checklist
In British Columbia, where the seasons can swing from blazing summers to snow-filled winters, seasonal generator service is more than a recommendation it’s a necessity. Preparing your generator for the seasonal shifts helps avoid surprises when the power goes out. Start by creating a checklist tailored to both summer and winter conditions.
During the summer months, focus on clearing debris around your generator to ensure proper airflow and cooling. Inspect the unit for signs of wear or insect infestations. Believe it or not, we’ve had cases where wasps made a home inside a generator cabinet, creating an unexpected maintenance headache. Also, check the cooling systems and make sure your generator starts easily. Monthly test runs during the off-season help keep the unit primed and ready.
As winter approaches, your maintenance priorities change. Cold temperatures can wreak havoc on fuel lines and batteries. Make sure your generator’s battery is in good condition and consider using a battery warmer to keep it functional. Inspect the antifreeze levels if you have a liquid-cooled generator. Snow and ice can block vents or exhaust outlets, so ensure the area around your unit is kept clear. It’s also a good time to review your fuel supply. If you use gasoline, remember that it has a limited shelf life. Using a stabilizer or rotating your fuel stock ensures reliability when you need it most.
Tailoring your generator maintenance to the season ensures consistent performance. A little seasonal prep can mean the difference between a smooth power transition and hours of stress in the dark. At Expert Electric, we encourage homeowners to schedule seasonal service checks to catch issues before they escalate.
Common Generator Problems And How to Avoid Them
At Expert Electric, we’ve seen just about every generator issue under the sun. From dead batteries to fuel that smells like it came from a science experiment gone wrong, the list of things that can go awry is long but manageable if you stay ahead of the game. Recognizing common problems is the first step to avoiding them.
One of the most frequent issues is a dead battery. Batteries degrade over time, especially if not used regularly. It’s important to test your battery at least twice a year and replace it every three to five years, depending on usage and environmental conditions. Don’t wait until a storm hits to find out your generator won’t start.
Another common culprit is stale or contaminated fuel. If you use gasoline, it can go bad in as little as 30 days. Using a fuel stabilizer and keeping your tank clean can help avoid clogging and poor engine performance. Diesel and propane also have their own storage challenges, so proper handling and periodic inspection are essential.
Loose or corroded electrical connections can cause power surges, startup failure, or uneven operation. Vibration from regular use can loosen components over time. Have a professional inspect all wiring and terminals during your generator service appointment.
Don’t forget about the exhaust system. A blocked or leaking exhaust can be dangerous and reduce performance. Make sure vents are clear and inspect for any signs of wear or rust.
By recognizing these problems and addressing them through regular generator maintenance, you can prevent costly generator repair and ensure your backup generator is ready when you need it.
When to Call the Pros
While some aspects of generator maintenance can be handled by a diligent homeowner, there comes a time when calling in the experts is not only smart but necessary. Certain problems require diagnostic tools, technical knowledge, and safety training that only a professional generator service technician can provide.
For example, if your generator is running but not supplying power, it may be due to a problem with the transfer switch or internal alternator. These are not components you want to tinker with on your own. Similarly, if you hear unusual noises, detect a fuel smell, or notice inconsistent performance, it is time to call in a professional. These symptoms often point to deeper issues that need immediate attention.
Routine maintenance should also involve a professional inspection at least once a year. A certified technician can check voltage output, perform load testing, inspect the fuel system, and tighten all electrical connections. This comprehensive review ensures your generator meets safety and performance standards.

Real Talk: Backup Generator Success Stories
At Expert Electric, we have had the privilege of helping countless homeowners and businesses across British Columbia stay powered up during outages. Some of our most memorable experiences have involved customers who invested in regular generator maintenance and saw firsthand how it paid off. Take, for example, a local organic farmer in Abbotsford. They rely on a backup generator to power their greenhouses, refrigeration units, and livestock pens. When a fierce November windstorm knocked out power for 48 hours, their generator kicked on instantly. Because they had kept up with their seasonal service schedule, everything worked flawlessly. Their plants stayed warm, animals were safe, and not a single tomato was lost. It was a real win for preparedness.
Another story comes from a bustling downtown Vancouver café that depends heavily on refrigeration and daily operations to serve its loyal customers. A surprise power outage during the holiday rush could have spelled disaster. Luckily, this business had partnered with us months prior for regular generator service and inspections. When the grid went down, their backup generator performed beautifully, allowing them to continue serving coffee, keep their pastries fresh, and maintain business as usual. Customers didn’t even notice anything had happened.
These are just two examples of how generator maintenance goes beyond convenience. It provides security, stability, and peace of mind when unpredictable weather or infrastructure failures strike. Keeping your backup generator in peak condition isn’t just a good idea, it’s essential to protecting the things you value most.
Generator Maintenance Myths Busted
In the world of generator maintenance, myths and misinformation abound. At Expert Electric, we often hear misconceptions that can lead homeowners to make risky or costly decisions. One common myth is that if you rarely use your generator, you don’t need to maintain it. This couldn’t be further from the truth. Just because your generator isn’t running doesn’t mean it isn’t aging. Oil can break down, batteries can lose charge, and fuel can degrade. A backup generator is like a fire extinguisher, you hope you never need it, but it had better work when you do.
Another widespread belief is that if your generator started fine last year, it will start just as easily this year. While that might be the case, it’s not something you want to gamble on. Environmental factors like humidity, temperature swings, and dust accumulation can affect performance from one season to the next. Without consistent service, you run the risk of it failing when it’s needed most.
Then there’s the do-it-yourself mindset. While it’s commendable to want to handle maintenance on your own, generators are complex systems. Tasks like load testing, inspecting electrical connections, and diagnosing fuel issues require specialized knowledge. Attempting repairs without proper training can lead to more damage or safety risks.
Trusting a professional generator service not only ensures the job is done right but also protects your investment. By debunking these myths and sticking to a proven maintenance schedule, you’re setting your backup generator up for long-term success and saving yourself from stress and high generator repair costs in the future.
