Common Generator Issues We Repair

Even the most durable backup generators require service from time to time. Our team can troubleshoot and repair nearly any issue to ensure your system is ready for the next outage.

Some of the most common repairs include:

• Failure to start – Often caused by battery issues, fuel problems, or faulty components
• Error codes or alarms – We interpret diagnostic messages and fix underlying issues
• Uneven or surging power output – Can result from load problems or engine malfunctions
• Fuel line or regulator issues – Especially common in propane or natural gas generators
• Low voltage or poor performance – Electrical faults or alternator issues may be the cause

If your generator is acting up—or hasn’t run its weekly self-test—schedule an inspection right away. Waiting can lead to more expensive repairs or total failure during an emergency.
