Your 5-Year Generator Warranty Isn't Five Equal Years

Updated October 28, 2026

Treat your generator's 5-year warranty as five flat years of the same protection and the headline has already fooled you. Pull up the actual coverage schedule and it reads like a staircase heading down. Full coverage — including the labor to fix things — only lasts two years. By year four it's quietly narrowed to the engine block and the alternator, and almost nothing else. Here's how the shrink works, and why it lines up with exactly the years your unit is most likely to break.

About five minutes. No salesman, no all-day window.

Five years on the box, two years of the good stuff

Generac spells it out in its own warranty sheet, and it isn't hidden — it's just worded so most people skim past it. Years one and two: parts, labor, and the technician's drive, all covered. Year three: parts only. The replacement part is covered; the person installing it isn't. Years four and five shrink again, down to the engine short block and the alternator's rotor and stator. The control board, the sensors, the wiring, the battery charger — if one of those quits in year four, that bill is yours.

It's a popsicle in a Florida parking lot. Full and solid when you carry it out, half gone by the time you've found your keys, and near the end there's mostly a stick. The word "five" never changes. What's behind it does, every single year.

The coverage thins out right as the unit starts to break

Here's the part that should bother you. A standby generator barely works for its first couple of years — it runs a short self-test once a week and kicks on during the occasional outage. The hard miles come later, and in Florida they come fast. Every storm season it runs for real, and the rest of the year it sits in salt air and humidity that chew on electronics. So the failures owners actually report — control boards, stators, charging parts — tend to show up a few years in, not in year one.

And those aren't small repairs. A stator or control-board fix runs roughly $1,200 to $2,800 once you add labor, according to a Generac dealer's warranty breakdown. Now line that up against the schedule: those failures cluster in years three through five — the exact window where the warranty has already dropped labor and most of the parts. You'd own a five-year warranty and a repair that five-year warranty won't fully touch, at the same time.

"Parts only" is the part that costs you

Labor is where generator repair gets expensive, which is why "parts only" isn't the deal it sounds like. The warranty can hand you a control board for nothing and still hand you a four-figure labor bill to put it in. There's a travel catch too — Generac's coverage pays for 100 miles and three hours of round-trip drive time, and if the nearest certified dealer sits farther out than that, the extra is on you. Kohler adds its own wrinkle: full parts-and-labor holds only if an authorized dealer does the repair. Let a regular electrician touch it and coverage can drop to parts only. Miss the registration window — 30 days for Kohler — and it can shrink or vanish entirely.

This is the whole reason owners buy the 10-year coverage before the 5-year starts tapering. The extended plan keeps labor and travel on the schedule through the years the standard warranty drops them — the years failures actually happen. On an air-cooled unit it runs around $1,035, and there's a trap in the timing: you generally have to buy it inside the first year of ownership. Wait until year three, when you can feel the coverage thinning, and the window to lock in the long version has already closed.

The number that actually tells you where you stand

All of this only matters next to one real number: what a properly installed, properly covered system costs at your address. Not a national average. Not a "starting at" figure that assumes a flat yard and a short gas run. Your specific house — the panel you've got, the distance to the meter, the unit your home actually needs.

That's what GENERasic puts in front of you up front: one committed installed price for your Florida address, warranty and all, before anyone sets foot on your property. Put in your address and get your price. Then you can decide about the 10-year coverage with the real math in front of you, instead of finding out what "parts only" means the hard way in year four.

Common questions

Does the 5-year generator warranty cover labor for all five years?

No. On Generac's standard air-cooled warranty, parts and labor are both covered only in years one and two. Year three is parts only. Years four and five cover just the engine short block and the alternator's rotor and stator. After year two, the labor on most repairs is your cost.

When do standby generators usually need their first big repair?

Later than people expect — and later than the full coverage lasts. The failures owners report most, like control boards, stators, and charging components, tend to cluster around years three to five, especially in Florida where storm-season run time and salt air are hard on electronics. That's the same window the warranty has already narrowed.

Is the 10-year extended warranty actually worth buying?

It mainly buys back the labor and travel coverage the 5-year warranty drops after year two — and labor is the expensive half of a repair. A stator or control-board job can run $1,200 to $2,800 with labor. If you're in a storm corridor or rely on the generator for medical equipment, the math usually favors the longer coverage. The catch: you generally have to buy it within the first year of ownership.

Do I have to register the generator, and how fast?

Yes, and the clock is short. Kohler wants the unit registered within 30 days of installation, and late registration can reduce or deny coverage. Generac also expects it registered with proof of purchase and maintenance on hand. Skipping the scheduled maintenance an authorized dealer is supposed to perform can void parts of the coverage too.

Does the warranty transfer if I sell my house?

Generac's standby warranty is transferable, but to the original installation site — not to a unit you dig up and move. So a buyer of your home can inherit the coverage that's left; you can't take it with you to the next house.

Portlandia Electric Supply (PES) — "A stator or control board repair typically costs $1,200–$2,800 with labor included; the standard warranty covers parts-only after year 2, forcing the customer to pay labor out of pocket during years 3–5 when failures peak."

Butler Mobility (Kohler dealer guide) — Kohler 5-year coverage is parts-and-labor if work is done by an authorized dealer; a non-network electrician means Kohler covers parts only. Serial-number registration required within 30 days or coverage can be reduced/denied.
Consumer Priority Service — "Most major failures—like control board, alternator, or starter issues—happen after the short manufacturer warranty ends, leaving homeowners responsible for the full repair or replacement cost."
