Reliable Generator Repair for Homes in Greater Chicago

When your backup power system is not working properly, prompt generator repair can help you avoid bigger problems later. A standby generator should start automatically, run smoothly, and be ready when the power goes out. If you notice warning lights, startup issues, unusual noises, or inconsistent performance, it is important to have the system inspected before a small issue turns into a major repair.

At Penco Electric & Generators, we provide generator repair for homeowners throughout Greater Chicago. Our team works to identify the source of the problem and restore safe, dependable operation as quickly as possible. Whether the issue involves the battery, wiring, transfer switch, control panel, or another key component, we focus on accurate diagnostics and lasting repairs that help protect your home during outages.

Professional generator repair also helps extend the life of your system and improve long-term reliability. Keeping your generator in good working condition means you can feel more confident when storms, winter weather, or unexpected outages hit the area. If your generator is not performing the way it should, Penco Electric & Generators is ready to provide trusted generator repair service for homes across Chicago and the surrounding suburbs.

The owner Paul was very helpful and was very knowledgeable about how the process would take place. The 3 man crew that came in was very helpful and accommodating. The project went smoothly. We would recommend this company.

Once again, Penco service gets 5 stars from me.  I had a small issue with my generator due to the extreme cold weather, and they were able to solve the problem right away.  I'm so happy I choose these guys for my generator and service work.

I had never heard of your company in the past.  However, all of the employees were courteous and completed my Generac standby generator in one day.  During the installation, my hot water tank's pilot went out.  The water stayed hot for one entire day.  The second day we noticed that the water was warm not hot.  I called the company and they came out on a Saturday evening to take care of the issue.  I was impressed with their service all around.

What made Penco the ideal company to work with on my Generac project comes down to this: they said what they would do, and then did exactly what they said!

Patrick was extremely helpful in walking through the project, and letting us know step by step what needed to be done beforehand, so that we weren’t surprised later on. Our lights look great, and we would definitely use Penco again.
