It’s Easy to Get Expert Generator Repairs

When your generator isn’t working properly, you don’t have time for complicated processes, long wait times, or unclear answers.

You need a straightforward solution and a team you can trust to handle everything. At GEM, we make generator repair simple from the first call to the final test.

Give us a call and let us know what’s going on. Whether your generator won’t start, is making unusual noises, or isn’t providing consistent power, we’ll gather the details and schedule a convenient time for service.

Once on-site, our technician will promptly inspect your generator and evaluate its performance. We take the time to pinpoint the root cause of the problem so you get a lasting solution.

After identifying the issue, we’ll explain your repair options in clear, simple terms. Once you approve the plan, we’ll complete the repairs quickly and efficiently, minimizing disruption to your home and routine.

Before we consider the job complete, we thoroughly test your generator to confirm safe and proper operation at peak performance. We make sure your whole-home or backup generator runs properly, and everything is operating safely and reliably.

Generator Not Working? We’ll Get You Powered Back Up.

When the power goes out, your generator should step in without hesitation; if it doesn’t, you’re left dealing with uncertainty at the worst possible time.

At GEM, we quickly diagnose and repair all generator issues, including:

You count on your generator to power up automatically, so when it doesn’t start, it’s frustrating and concerning. Whether the issue is worn spark plugs, a dead battery, fuel delivery problem, faulty starter, or control board malfunction, GEM will pinpoint the cause and get your system running reliably again.

If your generator kicks on but quickly shuts down, it may be detecting a safety issue or experiencing an internal fault. Low oil pressure, overheating, a clogged air filter, or sensor problems can all cause unexpected shutdowns. Our technicians perform a full system inspection to identify the issue and restore steady operation.

Generator batteries can weaken over time, especially if the system isn’t maintained regularly. If your generator fails its weekly self-test or shows battery alerts, we’ll test, replace, and ensure your charging system is working properly so you’re not left unprotected during an outage.

Standby generators rely on a consistent fuel source, whether natural gas or propane. Blocked fuel lines, regulator issues, or pressure problems can prevent proper operation. GEM’s experienced team will safely inspect your fuel system and make the necessary adjustments or repairs to keep your generator running smoothly.

Your automatic transfer switch is what signals your generator to turn on when the power goes out. If it fails, your generator may not activate, or it may not transfer power correctly to your home. We repair wiring issues, replace faulty components, and test your system to ensure seamless power transitions.

Modern generators use diagnostic systems to alert you when something isn’t right. If you see an unfamiliar error code or warning light, don’t ignore it. GEM technicians are trained to interpret manufacturer codes and resolve issues before they turn into bigger and more expensive problems.
