After the March 2026 nor'easter knocked out power to parts of Haverstraw, Stony Point, and New City for nearly four days, the phone at All American Electrical Service did not stop ringing. The first question almost every caller asked was the same: what does a whole-house generator really cost installed in New York? The honest answer for 2026 is $6,500 to $15,000 for most Hudson Valley homes, with the majority of jobs landing between $9,000 and $12,000 once you include the unit, the automatic transfer switch, the gas hookup, permits, and any panel work the home needs to support the new load.
That range is wider than the sticker prices you see online because the generator itself is only part of the bill. Owner Phil Garabo, a licensed electrician with 20+ years of experience installing standby systems across Rockland County, breaks down what drives that number, how the major brands compare in 2026, and where Hudson Valley homeowners can realistically save without cutting the corners that matter.
Standby generators are sized in kilowatts (kW), and the right size depends on how much of your home you want to keep running during an outage. Below are the typical fully installed price ranges All American Electrical Service is quoting in Rockland, Orange, and Westchester Counties in 2026.
These numbers assume a relatively straightforward install — a clear pad location within 15 feet of the meter and gas line, a panel that is in good shape, and standard Rockland County permits. Add roughly $1,500–$4,000 if the home needs an electrical panel upgrade to handle the new load, which is common in houses built before 1995. See our breakdown of electrical panel upgrade cost in Rockland County for what that work typically runs.
Three brands dominate the standby market in the Hudson Valley, and each has a real personality. Picking the right one is less about marketing and more about what you value: parts availability, warranty terms, quietness, or long-term build quality.
Generac holds the largest market share in New York for a reason — units are widely stocked, parts are easy to source from Albany-area distributors, and the Guardian and Protector lines cover everything from 10 kW to 26 kW. A 22 kW Generac Guardian typically runs $5,500–$6,200 for the unit alone in 2026. Generac's mobile app and Wi-Fi monitoring are the most polished in the industry. The trade-off: Generac uses an air-cooled engine on residential units up to 26 kW, which is noisier than liquid-cooled competitors and generally has a shorter expected service life under continuous load.
Kohler is the choice for homeowners who want the longest-lived unit and the quietest operation. The Kohler 20RCA and 26RCAL are commercial-grade engines repackaged for residential use, with a 5-year/2,000-hour warranty that beats Generac's standard 5-year limited coverage. Expect to pay $700–$1,500 more than a comparable Generac. Kohler also has stronger corrosion-resistant enclosures, which matters in the moist conditions of the lower Hudson Valley.
The dark horse of 2026. Briggs units are typically $500–$1,200 cheaper than equivalent Generac models and use a Vanguard commercial engine that has a strong track record. The catch is parts availability — service techs in Rockland County stock fewer Briggs parts, so warranty repairs can take longer. A good fit if you want strong hardware at a lower price and have a flexible timeline.
Two homes a mile apart in Rockland County can get quotes $4,000 apart for the same 22 kW generator. Here is what moves the number.
If your home still has a 100A service or an older Federal Pacific, Zinsco, or split-bus panel, it needs to be upgraded before a whole-house generator can be installed safely. Standby generators connect through an automatic transfer switch (ATS) that is sized to your main service, so a 100A service caps your generator capacity and creates code issues. Panel upgrades typically add $2,200–$4,500 to the project.
There are two paths: a whole-house service-entrance rated ATS (cleanest, most expensive, $800–$1,400 installed) or a sub-panel managed transfer switch that powers selected critical circuits ($400–$700 installed). Smart load management modules from Generac and Kohler now let smaller generators run bigger homes by shedding noncritical loads automatically — a real money saver if you do not need everything on at once.
Natural gas is the easier and cheaper option if your home already has a gas line — figure $400–$900 for the plumber to extend a sized line to the generator pad. Propane installs require a buried tank (typically 500 gallons for whole-home coverage), which can add $2,500–$4,000 if you do not already have one. Most homes in West Haverstraw, Garnerville, and Stony Point have natural gas available; rural addresses in upper Rockland and Orange Counties often need propane.
Rockland County jurisdictions (Haverstraw, Clarkstown, Ramapo, Orangetown, Stony Point) all require electrical and plumbing permits for standby generator installs, plus inspection by a third-party electrical inspector (typically Commonwealth or The Inspector). Combined permit and inspection fees run $300–$600. Towns also enforce setback rules — generators must usually be at least 5 feet from windows and doors and 18 inches from the house. A licensed installer handles all of this; a national chain often subcontracts it back to a local electrician anyway.
A 7,500-watt portable generator costs $900 and looks tempting until you live through a four-day February ice storm with two feet of snow on the driveway. Portables require you to be home, awake, and willing to refuel every 8–10 hours in the dark, plus drag heavy extension cords through the house. They cannot safely power 240V loads like your well pump, central AC, or electric range, and carbon monoxide poisoning from improperly placed portables kills New Yorkers every winter.
A standby generator starts automatically within 10–20 seconds of an outage, runs on the gas line that is already feeding your house, and can run continuously for days. For the kind of multi-day outages the Hudson Valley sees from nor'easters and ice storms — and increasingly from summer derechos — standby is the only option that actually keeps a household functioning.

Most Hudson Valley homeowners do not pay cash for a $12,000 generator install. The two main paths are manufacturer financing and home equity.
The big box stores and national generator chains will sell you a unit and subcontract the install — often to the same local Rockland County electricians who would have quoted you direct, but with a 20–30% markup baked in. More importantly, when the unit needs annual service or warranty work three years from now, you are calling an 800 number and waiting.
Phil Garabo and the All American Electrical Service team have been installing and servicing standby generators across Rockland, Orange, and Westchester Counties for over two decades. That means you get one accountable contact for the permit, install, inspection, annual maintenance, and any warranty issue down the road.

A typical installed whole-house generator in New York runs $6,500 to $15,000, including the generator unit, automatic transfer switch, gas/propane hookup, electrical work, and permits. Smaller 10–14kW units fall at the lower end; larger 22–24kW systems for bigger homes reach the upper end. Hudson Valley installs often run slightly higher due to permitting, fuel-line work, and panel upgrades on older homes.
Most installs are completed in one to two days of on-site work, but the full project timeline from contract signing to a running generator is typically 4–8 weeks. The main bottleneck is permit approval and inspection scheduling in Rockland County, not the install itself. Panel upgrades or propane tank work can add another week.
Yes, but modestly. Appraisers in the Hudson Valley typically add $3,000–$6,000 in value for a properly installed whole-house generator, and homes with standby power tend to sell faster after a major regional outage. The bigger return is insurance — many carriers offer a 3–5% discount on homeowners premiums for homes with permitted standby generators.
Manufacturers require annual maintenance to keep the warranty valid — typically an oil change, filter replacement, spark plug inspection, and load test. Most Hudson Valley homeowners on natural gas budget $250–$400 per year for a maintenance contract. Generators also self-exercise weekly for 5–15 minutes to keep components lubricated.
