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.

I was not a service call. It’s just a yearly check up on the air conditioner. I did not meet Thomas personally, but my wife said he was very nice man. you must’ve needed a garden hose for something.

Tony and Kevin were great, very professional and very knowledgeable- they listened to what I thought was going on, started there and quickly solved the A/C airflow issue.

Technicians Steve Gray and Chase were Outstanding in every detail from presentation to knowledge , expertise and commitment to resolving my problem. I am a very please customer and I just need to say Steve and Chase represent your company extremely well. I will continue to be a very loyal customer. Thank you
Xavier and Mike did an excellent job.
We were very happy with the Service! Jacob and his “understudy” showed a very professional and efficient service. Jacob seem to be very experienced, and knowledgeable, and can think outside of the box. For over 20 years every time we had the boiler serviced, louvre was recommended as a solution for the low air supply.. Jacob saw the unused 4 inch dryer duck which is already in place and with minor modification can provide more air, which I thought was a brilliant idea. Highly recommend this team to anyone!
Nicholas from GEM was very informative and fixed our problems and gave good advice. Thank you!
Generator maintenance. Excellent in all respects.
Douglas is terrific!
Orlando and Marcello are true superstars of your business! Polite, very quick at helping me fix my problem with my Plumbing. The whole process from start to finish was handled beautifully thank you so much for making a stressful situation so much easier!
Excellent work on a variety of household electrical needs. Service techs were professional, friendly, and all work done to high standards!
Excellent service! Gem Plumbing was professional, responsive, and arrived on time. They quickly identified the issue with the roof drain pipe, clearly explained the repair, and completed the work efficiently. The quality of the workmanship was excellent, and everything was left clean when the job was finished. I would definitely recommend them to anyone looking for a reliable plumber.
Excellent service with clear explanation. On time, friendly professional communication. Issues resolved with creativity!
Cory was very knowledgeable and respectful.
