A standby generator that won't start is only discovered at the worst possible moment, in the dark, mid-storm. We diagnose and fix the faults, failed self-tests, and dead batteries that keep them from running, so yours is ready when the grid isn't.
Most failures start small and quiet. Caught early, they're a simple fix, not a cold night.
Tap what you're seeing for a quick read on how serious it is and whether it's something to schedule or call about now. The status light shifts with your pick.
Tap one of the symptoms and we'll tell you what it likely points to and what the right next step is.

A standby generator has an unusual job. It sits quietly for months, then has to fire up and carry your whole home the one time the power drops. That pattern, long idle stretches followed by a sudden demand for perfection, is exactly what causes most failures.
The usual culprits are simple: a battery that quietly died between storms, fuel or oil issues, a controller that logged a fault and locked out, corroded connections, or a transfer switch that isn't handing over power. None of these announce themselves in the moment you need the generator, which is why they catch people off guard. The good news is that nearly all of them are straightforward to fix once you find them, and finding them early is the whole game. If yours is beyond repair or was never sized right, we can talk through a fresh installation instead.
We service what's out there, with a soft spot for Generac since it's what we install most. Whatever brand sits along the side of your house, we can diagnose why it isn't doing its one job and put it right.
Cranks without catching, or does nothing at all. Usually battery, fuel, or ignition.
Fires up then shuts down, often a protective response to low oil pressure or heat.
The engine runs but the house stays dark, pointing at the transfer switch, not the engine.
A red alarm and a code on the controller mean it stopped itself and needs a read.
The quiet killer. A weak battery is the most common reason a standby won't wake up.
The weekly exercise cycle didn't complete, an early warning worth acting on.
A yellow light flagging oil, filter, or battery service that's come due.
Terminals, sensors, and connectors that age in the weather and need attention.
Here's the thing most people don't realize: a standby generator gives you plenty of warning before it fails. Once a week it runs a short self-test, and a failed test, a warning light, or a logged code is the unit telling you something's wrong while the sun is still out and there's no pressure.
The trouble is that nobody's watching the side of the house on a Tuesday afternoon. That's where remote monitoring earns its keep. Generac's Mobile Link sends the unit's status to a phone, so a problem surfaces the week it happens, not during the next storm. We can help you set that up, keep an eye on it, and dig into the Generac systems we know best. Catching the warning is what turns a repair into a scheduled visit instead of an emergency.
A generator that fails when you finally need it is worse than no generator at all, because you were counting on it. Nearly every failure we're called out for during a storm could have been caught on a calm day by a self-test that went unnoticed or a service that was overdue.
That's why we lean so hard on prevention. A periodic service to check the battery, oil, and connections is a small thing that keeps the unit ready, and it pairs naturally with the rest of your home's electrical maintenance. If the worst does happen mid-storm, our emergency line is answered 24/7.
We service standby generators across Waldwick and the boroughs around it, including Ridgewood, Ho-Ho-Kus, and Allendale, plus Wyckoff, Midland Park, Saddle River, Franklin Lakes, Glen Rock, and Ramsey. Being close by means we can get to a storm-day failure quickly, and it makes routine service easy to keep up. It's part of the full-home care behind all our residential work.
Frequent storms mean generators that run often and earn their keep, and their service.
Whole-home units on bigger properties where a failed switchover matters most.
Units that have been in a few years and are due for battery and service attention.
Our home base, where routine service and storm-day calls are both quick to reach.
A homeowner's generator did nothing during an outage. The battery had quietly failed months earlier and no one knew. We replaced it, tested the full start-up, and set them up with monitoring so the next one gets flagged early.
A unit kept firing up and shutting down seconds later. The controller had logged a low-oil-pressure fault. We traced and fixed the cause, cleared the code, and confirmed a clean run under load.
The generator ran fine but no power reached the home. The issue was the transfer switch, not the engine. We repaired the switchover so the unit actually does its job when the grid drops.
One call gets a real electrician out to diagnose a fault or service the unit, so it's ready the next time the grid isn't.
