“This was the second time I used Certified Electric for electrical work. Jalan arrived on time to install 3 ceiling fans.The service was completed in about an hour. I was able to confirm everything was working properly for each fan before Jalan left. I would definitely recommend Certified Electric to family and friends.”

Certified Electric
Protect your home from outages with a safe, reliable generator installed by Certified Electric.

We install backup power systems that keep your home safe, comfortable, and running during outages.
We start with an on-site visit to review your panel, meter, service size, and the circuits you want backed up. Then we calculate your home’s electrical load, recommend the right generator and transfer switch, and give you a clear timeline and upfront estimate.
Once you approve the plan, we handle the electrical side of the project, including permit requirements, installation planning, and coordination for a smooth setup. We install the generator connection, transfer equipment, and all required wiring to code, with careful attention to safety, neat workmanship, and long-term reliability.
After installation, we test the full system, confirm proper changeover during a power loss, and check that every connection performs as it should. Before we wrap up, we walk you through generator operation, maintenance basics, and what to expect during outages so you feel confident using your new backup power system.
Power outages can shut down more than the lights. They can stop your furnace, sump pump, refrigerator, Wi-Fi, medical equipment, and security systems. At Certified Electric, we install whole home generators that help keep your home safe, comfortable, and running when the utility power goes out.
A whole home generator is a permanent standby system that turns on automatically when it senses a power loss. Unlike portable generators, these systems are connected to your home’s electrical system through an automatic transfer switch. That means no extension cords, no manual setup in bad weather, and no guessing about what can run safely.
Our generator installation service starts with a full evaluation of your home’s electrical needs. We look at your panel, service size, major appliances, HVAC equipment, sump pump, and any critical circuits you want backed up. From there, we help you choose the right generator size and layout for your property and power goals. Some homeowners want essential backup power only, while others want coverage for the entire house.
We handle the electrical side of the project with a focus on safety, code compliance, and long-term performance. This includes installing the transfer switch, connecting the generator to the electrical panel, verifying load requirements, and testing system operation. We also make sure the installation is clean, organized, and built to perform when you need it most.
Homeowners in Matteson and the surrounding suburbs count on us because we understand service upgrades, panel upgrades, and troubleshooting. That experience matters when adding a standby generator to an existing electrical system. If your panel needs updates or your service entrance needs attention, we can identify those issues before they become problems.
Whole home generator installs are a smart fit for homes with finished basements, home offices, refrigerated medications, flood concerns, or frequent storm outages. They can also add peace of mind if you travel often or want your home protected during winter weather and summer heat.
If you are thinking about a standby generator, we are here to help you make the right choice for your home and budget. Contact Certified Electric to schedule a generator installation assessment and get dependable backup power from licensed electricians who know how to do the job right.
