Customer Questions: How long is the warranty on a DuroMax generator?
Updated September 22, 2026
DuroMax warranty coverage depends on the product line and whether the equipment is used residentially or commercially. Most current DuroMax generators and power equipment are listed with a three-year residential warranty and a one-year commercial warranty. Select HX, HXT, iH, and iHT lines are listed with five-year residential coverage, although DuroMax identifies exceptions within the inverter range.
How Long Is the Warranty?
| Product category | Residential use | Commercial use |
|---|---|---|
| Most generators, engines, pumps, and pressure washers | 3 years | 1 year |
| Select HX, HXT, iH, and iHT premium series | 5 years | 1 year |
| Cords, accessories, and related items | 30-day satisfaction guarantee rather than standard equipment coverage | Check current terms |
Coverage can change, and exceptions apply. For example, DuroMax currently lists the XP2300iH, XP4500iH, and XP9000iH with three-year residential rather than five-year coverage. Confirm the exact model's product page and written warranty in effect when you purchase.
When Does Coverage Begin?
Keep the dated sales receipt and delivery record. The warranty period is tied to the original purchase or delivery, subject to the manufacturer's current terms. Registering the generator does not replace proof of purchase, but registration can help DuroMax associate the model and serial number with the owner.
Use the official DuroMax product-registration page and retain a copy of the confirmation.
What Is Commonly Excluded?
DuroMax's published exclusions include normal wear, maintenance services, cosmetic defects, accessories, damage associated with natural disasters, and failures related to aftermarket or non-OEM parts. Abuse, neglect, improper maintenance, or unauthorized modification can also affect coverage.
- Follow the break-in and maintenance schedule in the exact model manual.
- Use the specified oil, filters, spark plugs, and replacement parts.
- Document maintenance dates, hours, and receipts.
- Do not modify the exhaust, fuel system, electrical output, or emissions equipment.
- Contact support before authorizing major warranty repairs.
How to Make a Warranty Claim
- Record the model, serial number, hours, purchase date, and symptoms.
- Photograph the unit and any displayed fault information.
- Locate the receipt and maintenance records.
- Contact DuroMax technical support before shipping or disassembling the generator.
- Follow the assigned troubleshooting, service-center, parts, or return process.
DuroMax states that warranty repairs may be handled through its distribution or service centers. Freight, downtime, and incidental losses may not be covered, so read the limitations before arranging transport.
Warranty vs. Emissions Coverage
The product warranty and the emissions-control warranty are separate. DuroMax publishes a two-year emissions-system warranty statement with its own covered components and owner responsibilities. That coverage should not be confused with the three- or five-year residential equipment warranty.
Before You Buy
Download the model manual, save the product-page warranty language, and confirm whether your intended use is residential or commercial. Browse current units in the DuroMax portable generator collection, then verify coverage for the exact SKU.
Bottom Line
Most DuroMax equipment currently carries three-year residential and one-year commercial coverage, while select premium series offer five-year residential coverage. Exceptions and exclusions matter, so preserve your receipt, register the product, follow the maintenance schedule, and review the current written policy.
