How long is the Generac warranty?
Generac home standby generators carry a 5-year limited warranty (often structured as 5 years parts / 5 years labor on Guardian series, with year-by-year component schedules). Portable generators typically carry 2–3 years for residential use, halved for commercial use. Promotional 10-year warranty extensions are frequently offered through installers and retailers like Costco — if you bought recently, check your paperwork, because that free extension is real and worth registering.
Two requirements matter at claim time: installation by a qualified installer (for standby units — DIY electrical installation can void coverage) and documented maintenance using Generac-spec parts. Generac explicitly requires Generac-branded maintenance parts to keep the warranty intact. Warranty service goes through the authorized dealer network, not Generac directly.
How to file a Generac warranty claim
Find your proof of purchase
Locate the receipt, order confirmation, or card statement showing the purchase date — coverage is measured from it.
Locate the model & serial number
Usually on a label on the unit, in the manual, or in your online account. Generac support will ask for it first.
Contact Generac through an official channel
Use the support number or claim form on their official site — not third-party sellers — so your claim is on record with the manufacturer.
Document everything
Save case numbers, names, dates, and photos of the defect. A clear paper trail resolves disputes faster.
Escalate if needed
If a valid claim stalls, ask for a supervisor and reference your statutory rights as a consumer (see our warranty types guide).

Repair or replace your Generac? A quick rule of thumb
The common guidance: if the repair costs more than half the price of a new unit, or the unit is past ~75% of its expected lifespan, replacement usually wins. For major sealed-system or compressor failures out of warranty, repairs can run $400–$1,000+, which often tips toward replacing — but always get a diagnosis first.
