If you’ve started shopping for a standby generator, you’ve probably noticed the same handful of brand names coming up again and again: Generac, Kohler, Cummins, sometimes Briggs & Stratton. All of them make legitimate, well-established equipment, and any of them can be a good fit depending on your home, your budget, and what you actually need the generator to do during an outage.
So how do you actually choose? Not by chasing a spec sheet, but by understanding the handful of things that make a real difference once the generator is sitting in your yard and the power actually goes out.
Brand Reputation Isn’t the Whole Story
Generac is the name most homeowners recognize first, and for good reason — it’s been in the home standby generator business for decades and has a large footprint of dealers and service technicians across the country, including here in the Pacific Northwest. Kohler and Cummins both have strong reputations too, particularly Kohler’s history in industrial and marine engines, which carries over into their generator line.
Here’s the thing that matters more than the badge on the unit: who’s going to install it, and who’s going to show up when it needs service five or ten years from now? A generator is a long-term piece of home equipment, not a one-time purchase you forget about. The brand matters less than having a local, licensed installer who knows the equipment and will actually answer the phone later.
Noise Levels Are Closer Than You’d Think
Noise is one of the most common questions we get, especially from homeowners on smaller lots or in neighborhoods with houses close together. The honest answer is that modern standby generators across all the major brands have gotten quieter over the years, and the difference between comparable models from Generac, Kohler, and Cummins tends to be smaller than marketing pages make it sound.
What actually affects how much you notice the noise is placement — how far the unit sits from bedroom windows, whether there’s a fence or structure between the generator and your outdoor living space, and how your property is laid out. That’s a conversation worth having with whoever does your site evaluation, regardless of which brand you land on.
Fuel Type Matters More Than Brand
Most standby generators run on natural gas or liquid propane, and this decision usually has more impact on your day-to-day experience than the brand choice does. If you already have a natural gas line to your home, that’s typically the simplest and lowest-maintenance path — no tank to monitor, no deliveries to schedule. If you’re on propane, you’ll want a properly sized tank and a plan for keeping it filled, especially heading into storm season.
This is a decision worth making with your installer before you fall in love with a specific model, since not every generator size and fuel combination is available or practical for every home.
Sizing Is Where Most Mistakes Happen
Regardless of brand, the single biggest factor in whether a generator actually does its job is whether it’s sized correctly for your home. Undersized units struggle to run your essentials during an extended outage; oversized units cost more upfront and to install than they need to. This isn’t something to guess at — it comes down to a real load calculation based on your electrical panel, your major appliances, and what you actually want powered when the grid goes down (just your essentials, or your whole house).
We’ve put together a separate guide on how to figure out what size generator you actually need if you want to go deeper on that specific question.
Dealer Network and Local Support
One real, practical advantage to Generac specifically in this region is the density of authorized dealers and service technicians, us included — Mauro Electric is an authorized Generac dealer, and we install, hook up, and service standby generators throughout Snohomish and King County, from Seattle and Bellevue up through Everett and out to Snoqualmie and the islands. That local presence matters when you need a warranty service call or annual maintenance, not just when you’re buying the unit.
That said, if you already own a Kohler or Cummins unit, or you’re set on one for a specific reason, a licensed electrician can still evaluate, install, and service it — the brand doesn’t have to be Generac for the safety and code requirements to be handled correctly.
What We’d Actually Tell a Homeowner
If you asked us directly: for most homes in our service area, Generac is a safe, well-supported choice, mainly because of how easy it is to get local service and parts. But the brand is genuinely the smaller decision here. The bigger ones are correct sizing, the right fuel setup for your property, and — most importantly — having a licensed, insured electrician handle the installation and gas/electrical hookup rather than treating it as a project to piece together yourself. Generator installation involves gas line work, transfer switch wiring, and permitting that has real safety consequences if done incorrectly.
Mauro Electric has been a family-owned, licensed electrical contractor in Bothell since 1998 (electrical license MAUROEI971BA), and we’re proud of the reputation we’ve built along the way — 4.9 stars across 200+ Google reviews from real customers in the neighborhoods we serve. If you’re weighing your options for a standby generator, we’re happy to walk through what a whole-house installation actually involves and help you figure out what makes sense for your home.
Frequently Asked Questions
Is Generac better than Kohler or Cummins?
Not universally — all three are legitimate, well-established brands. What tends to matter more for most homeowners is correct sizing, the right fuel setup for the property, and having a local, licensed installer who can service the unit for years to come.
Do I need a permit to install a standby generator?
Yes. Standby generator installation involves both electrical and gas work, so it typically requires a permit and inspection regardless of brand.
Can I install a standby generator myself?
No — this involves gas line work, transfer switch wiring, and permitting with real safety consequences if done incorrectly. It should always be handled by a licensed, insured electrician.
