Hi-Lite Electric provides generator installation and service for homes and businesses throughout Warrenville and the surrounding DuPage County area. We are a family-owned electrical contractor with the equipment, training, and local knowledge to handle everything from whole-home standby generator installs to commercial backup power systems.
When you reach out to Hi-Lite, we start by understanding the scope of what you need before anything else, and for generator work that almost always means an on-site visit to assess your electrical service, available space, fuel source, and load requirements. Once we have a clear picture, we provide a straightforward project quote with no surprises. Our Warrenville clients can expect a scheduled installation that respects their time, a crew that works clean, and a finished installation that is code-compliant and ready for inspection.

Adding a generator is often the starting point for a broader conversation about your property’s electrical capacity, and Hi-Lite is well-positioned to guide that planning for both Warrenville homeowners and business owners. Whether you are thinking about adding an EV charger alongside your generator or planning a larger electrical upgrade down the road, we can help you think through sequencing so your projects build on each other efficiently. Think of Hi-Lite as a long-term resource, not just a one-time contractor.
Generator installation estimates vary based on generator size, transfer switch type, fuel source, and the condition of your existing electrical service. We provide a clear project quote after assessing your specific situation, so you know exactly what is included before any work begins.
Yes, standby generator installations in Warrenville typically require a permit through the city, and the work must be performed by a licensed electrician. Hi-Lite has direct experience working with local DuPage County municipalities and handles permit coordination as part of the installation process.
Generator sizing depends on which circuits or equipment you need to power during an outage, from essential appliances to full whole-home or commercial coverage. We assess your load requirements during the on-site visit and recommend a size that fits your actual needs, not a one-size-fits-all approach.
A transfer switch is an electrical device that safely connects your generator to your home or building’s circuits while isolating it from the utility grid, which is required for safe and code-compliant operation. Hi-Lite installs both automatic and manual transfer switches depending on your generator type and preferences.
Hi-Lite offers 24/7 availability for generator service calls, including after-hours and emergency situations. Our vans are fully equipped so we can respond any hour without waiting on parts or equipment sourcing.
