Generator Repair vs. Replacement: Which Is Right for You?

June 24, 2025

Generators are essential for keeping your home or business running smoothly during power outages. When a unit begins to malfunction, it's important to weigh your options carefully. Deciding between repairing your generator or replacing it entirely often comes down to a few key factors, including cost, performance, and the age of the equipment. Understanding these considerations can help you make an informed decision and avoid unnecessary downtime.


Consider the Age of Your Generator

Age plays a major role when choosing between repair and replacement. In our experience, most generators have a useful life of 10 to 30 years, depending on the type and how often they're used. If your generator is near the end of its expected lifespan, replacement may be the more cost-effective option. Older units may suffer from reduced efficiency and outdated components, which can lead to more frequent breakdowns and mounting repair costs.


Evaluate the Repair Costs

Frequent or expensive repairs are often a sign that it's time to invest in a new unit. We've concluded that if the cost of repairs approaches 50% of the price of a new generator, replacement is typically the smarter move. On the other hand, if your generator is relatively new and has only experienced a minor issue, repair is likely the more practical solution. A professional offering generator services can provide a clear breakdown of what's involved and whether further investment makes sense.


Look At Efficiency and Performance

Even if your generator can be repaired, it may not run as efficiently as newer models. If you've noticed increased fuel usage, inconsistent performance, or longer startup times, your generator may be underperforming. A replacement can improve energy efficiency and reduce operating costs over time. According to Fortune Business Insights, the U.S. generator sales market was valued at $6.10 billion in 2023, highlighting the importance of purchasing a replacement when necessary. Technicians experienced in generator services can assess the performance of your current unit and help determine if a new model would provide better long-term value.
