PowerSource engines for one ton and under applications are warranted against defects in workmanship and materials for 3 years or 100,000 miles, whichever comes first. You can read the full terms of the warranty here. We also offer two upgrade options on the warranty:

Our Silver warranty upgrade changes the status of the warranty to full no fault status. This means that regardless of cause of failure, you're guaranteed a one time replacement and labor, under the terms of the original warranty. The cost is $149 extra.

Our Gold warranty keeps the no fault status of the Silver warranty but increases the labor reimbursement from $50/hr to $85/hr under the terms of the original warranty. The cost is $349 extra.
