Maintenance & Seasonal Care
A little regular care is all it takes to keep an inverter generator ready for the day the power quits — and it's about as involved as looking after a lawn mower. Check the oil, keep the fuel fresh so it doesn't gum up, run it for a few minutes each month, and give it a simple seasonal once-over. Here's the plain-English routine, with a printable, 29-page guide up top if you'd like the full walk-through.
Common Questions
1 How often should I change the oil in my inverter generator?
Two rules cover it. When the unit is new, most makers want an early break-in oil change after just the first few hours of running, to flush out the tiny metal bits an engine sheds as it wears in. After that, change the oil roughly every 100 run-hours, or at least once a year even if you haven't run it that much, or whatever your owner's manual says. Check the oil before every use too, and top it to the mark with the weight your manual calls for.
2 Why won't my generator start after sitting all year?
Nine times out of ten, the answer is stale fuel. Gasoline goes bad in a matter of months, and as it ages it leaves a sticky varnish that gums up the carburetor's tiny passages — so the engine cranks but won't catch. It is the number-one reason stored generators won't start. The cure is prevention: use fresh fuel, add a fuel stabilizer if it will sit more than about a month, and either keep the fuel fresh or run the carburetor dry before long storage, as your manual describes.
3 Do I really need to run it when there's no outage?
Yes, and it is one of the kindest things you can do for it. About once a month, start it and let it run 15 to 20 minutes with something light plugged in. That keeps fresh fuel moving through the system, charges the battery on electric-start units, drives off moisture, and — best of all — proves the machine starts and runs months before you would stake a freezer of food on it. Always run it outside, well away from the house.
4 What maintenance does an inverter generator actually need?
Less than you might fear — it is much like caring for a lawn mower. Check the oil before each use and change it on schedule; keep the air filter clean; inspect the spark plug now and then; keep the fuel fresh with stabilizer; run it about once a month; and, on electric-start units, keep the battery charged with a battery tender. Store it clean and covered when it is cool and off, keep a simple log, and let your owner's manual settle the exact numbers.
5 What's different if I only use it for storms versus using it a lot?
It comes down to the calendar versus the hours. A storm-only generator that mostly sits is cared for by the calendar — the monthly run and fresh, stabilized fuel matter most, and you change the oil at least yearly even though you rarely reach 100 hours. A heavily used unit — on a well, a jobsite, or a camp — reaches every mark faster, so watch the oil and air filter closely and keep spares of oil, a filter, a plug, and stabilizer on hand.
6 Can I do this myself, or do I need a mechanic?
Almost all of it is homeowner-friendly — if you can run a lawn mower and follow a checklist, you can keep a generator maintained. Oil, filter, spark plug, fuel care, and a monthly run are all things I'm glad to teach you to do yourself. The only jobs that call for a licensed electrician are hookups to your home's wiring, like a transfer switch for a well pump. If you would rather have a hand getting started, that is exactly what I do — call Bill's Home Tech at (330) 200-8042.
Want a Hand With Yours?
Picking a generator, setting it up, and learning to run it safely is one of my most-requested visits. I bring the patience and the know-how - you keep your seat. We'll match a unit to your home, set it up right, walk through starting it and staying safe from carbon monoxide, and get your internet, TV, and devices happily back on. $99 flat, and every visit is 30-day come-back-free. (330) 200-8042.
Would you rather I just do this for you?
No shame in it — plenty of folks would rather hand it off, and that's what I'm here for. I'll come to your home, set it up right, and make sure it's working before I leave. Flat $99 per visit — no jargon, no upsell, and every visit is 30-day come-back-free.
Not a hardware job? I can often fix it remotely for $49 — a secure screen-share, up to 2 hours, that you watch the whole time and can end whenever (included free for $39/mo Support Plan members, and it counts toward the $99 if it turns out I need to come out).
