Generac's latest earnings reveal something interesting about backup power demand. The opportunity for contractors may have less to do with the next storm than what happens after it.
Everyone's talking about the grid
Spend an evening on X or YouTube and the power grid starts to look like it has about six weeks to live. There are videos on surviving a year without electricity, long threads about transformer shortages, and an impressive number of ads for buckets of freeze-dried lasagna.
Most homeowners aren't building bunkers. But plenty have spent a few hours in the dark, wondering whether the sump pump will hold out or how long the food in the freezer will last.
Full disclosure: I've stocked up on a few extra cases of bottled water and some cans of Beanie Weenies myself.
Those are ordinary worries. A gas furnace that can't run its blower without electricity. A home office, a CPAP machine, an aging parent. None of that requires believing the grid is about to collapse. It only requires having lived through one bad outage.
Generac's numbers tell a more interesting story
Generac, the company most people picture when they hear "whole-house generator," reported third-quarter results on October 28. Its residential business grew about 9% to $744 million. Shipments of home standby generators rose at a mid-teens rate over last year, mostly on volume rather than price increases. In-home consultations, the sales appointments Generac tracks as leads, rose sharply, with the most strength in the Midwest and Northeast. Its dealer network reached nearly 9,900.
Before anyone declares a boom, look at what it's growing from. Generac said the second half of 2025 saw the lowest level of total outage hours in a decade, and its fourth-quarter 2025 home standby shipments fell 25% from a year earlier, when several major hurricanes had boosted demand. The 2026 hurricane season had been relatively quiet through September, too. What brought buyers back was everyday severe weather, especially late-summer storms across the Midwest and Northeast. Thunderstorms, not the end of civilization.
As for market size, Generac estimates about 6.75% of the single-family homes it considers its market have a standby generator. A generator company will always tell you the market is underpenetrated, so treat that as their number. Still, most homes have no automatic backup at all.
Two details are worth slowing down for.
First, interest and installations didn't move together. Shipments are generators Generac sells to dealers and retailers. Activations are generators actually installed and switched on in somebody's side yard. For the quarter, activations were roughly flat, turning positive in September for the first time since the second quarter of 2025. On the earnings call, CEO Aaron Jagdfeld explained that installs fell in some states because the year before had benefited from the "afterglow" of an active 2024 hurricane season. Demand shows up after an outage, lingers for a while, and fades.
Second, Generac says more than half of its standby buyers previously owned or currently own a portable generator. Plenty of people buy a portable after one rough night, live with the extension cords and gas cans, and come back for a permanent system later. Sometimes much later.
Put those two facts together and the real story comes into focus. A storm creates interest. The homeowner researches options and gets an estimate. The lights come back on and the urgency fades. When they're finally ready to buy, the contractor who stayed in touch has a much better shot at earning the job.
The opportunity is bigger than the generator
The generator is the box. The job is everything around it.
Someone has to figure out what the house actually needs to run, assess the electrical panel, and help the homeowner choose between whole-home coverage and essential circuits. Fuel supply, permits, installation requirements, and ongoing maintenance all factor into the decision.
That is work for licensed electricians and, on the fuel side, licensed gas fitters or plumbers, depending on your state. It isn't automatically work for an HVAC company, and nobody should read this as permission to wire a transfer switch without the license to do it.
HVAC contractors still have a real role, and for many of them the opportunity is sitting in the customer database rather than on the installation crew. You already know which customers have heat pumps, backup heat requirements, or electrical systems worth a closer look. Your techs may also hear firsthand about recurring outages. A referral partnership with a qualified electrical contractor, plus some honest customer education, puts you in the conversation. You don't have to become a generator installer to be part of it.
The smaller jobs count too: inlets and interlock kits for portable owners, and maintenance plans for existing standby units.
Don't sell fear. Sell a plan.
This category practically begs for scare tactics. Resist them.
A permanently installed standby generator is a significant household investment. Depending on the equipment, electrical work, fuel supply and site conditions, the final price can run well into five figures. That deserves a straight conversation, and the good version sounds like an advisor working through honest questions with the homeowner. What has to keep running: the sump pump, the fridge, the furnace, a medical device? How long do outages usually last on this street? Does the whole house need coverage, or a dozen circuits? What will fuel and annual service cost? Would a portable with a proper transfer setup cover most of what matters for far less money?
Local context beats national headlines. EIA data show the average U.S. customer lost power for about 11 hours in 2024, nearly double the prior decade's average, but major events led by Hurricanes Beryl, Helene and Milton accounted for 80% of those hours. Outside major events, the typical customer loses about two hours a year. A contractor who knows their own area's outage history is more credible than one quoting the internet.
Fear might close a deal now and then. It won't earn you the next three calls when the neighbors notice whose lights stayed on.
Don't let the afterglow fade
Here's how a lot of these opportunities actually die.
A homeowner calls after a storm. The contractor visits, checks the panel, talks through options and sends an estimate. The homeowner says they need to think about it.
And then? Nothing. No follow-up. No explanation of financing. No side-by-side of whole-home versus essential-circuit backup. No check-in before storm season. Six months later the power goes out again, and they buy from whoever reached them first.
The contractor didn't lose the job because they needed more leads. They lost it because they stopped following up.
That's a revenue leak.
Fixing it doesn't take a bigger ad budget. Treat "thinking about it" as an open opportunity with a date attached, not a lost one. Write down why they called, whether it was the sump pump, the home office or the parent on oxygen, because that reason is your follow-up. Send a short written comparison of the options you discussed, with financing spelled out. Contact every open estimate before your area's storm season, and again after the next regional outage, when the afterglow comes back. And keep track of customers who already own portable generators. They're a logical audience for an educational conversation about permanent backup power, even if they're years away from buying.
For installed customers, the maintenance agreement is the follow-up. An annual visit keeps the unit ready and keeps your truck in the driveway when they start thinking about the next project.
The contractors who benefit most from this demand probably won't be the ones with the biggest ad spend. They'll be the ones who help homeowners make a clear decision, and who are still around when the homeowner is ready to make it.
The next outage will get homeowners thinking about backup power again. That's predictable.
What's less predictable is whether they'll remember the contractor who gave them an estimate six months earlier.
Give them a reason to.
