FAQs
What types of generators does your Andersonville electrical team service and install?
Our licensed electricians work with all major categories of residential and light-commercial generators—including air-cooled and liquid-cooled standby units, whole-home inverter generators, portable backup units, and natural-gas or propane fueled systems. We are factory-trained on leading brands such as Generac, Kohler, Cummins, and Briggs & Stratton, so we can handle installation, warranty repair, and preventive maintenance for virtually any model you own or plan to purchase.
How often should a standby generator be serviced in Andersonville’s climate?
For typical Chicago weather conditions, we recommend two professional service visits per year: a pre-summer inspection to prepare for severe storms and a pre-winter check to ensure cold-weather reliability. At minimum, your generator needs an annual oil and filter change, battery test, coolant level check (for liquid-cooled units), and a full system load test. Frequent weekly or bi-weekly self-exercising (either manual or automatic) keeps internal parts lubricated between visits.
Do I need a permit to install a residential generator in Andersonville?
Yes. The City of Chicago requires an electrical permit and, in most cases, a separate plumbing permit for the natural-gas connection. Our team handles the entire permitting process—we submit drawings, load calculations, and compliance documents to the Department of Buildings, schedule all required inspections, and ensure the installation meets NEC, municipal, and ComEd interconnection standards.
How long does generator installation take, and will my power be interrupted?
A typical turnkey installation for a pre-sized residential standby generator takes one to two full days. Day one covers site preparation, mounting the generator, routing conduit, and setting up the automatic transfer switch (ATS). Day two involves fuel piping, final electrical terminations, start-up, and inspection. Your home may experience a brief outage—usually less than 30 minutes—while we transfer circuits to the ATS, but we schedule this step at a time that minimizes inconvenience.
Can you help me choose the right generator size for my property?
Absolutely. During a free on-site assessment, our technicians evaluate your square footage, HVAC loads, essential circuits, and any special equipment (medical devices, sump pumps, servers). We then run a detailed load calculation to recommend the smallest generator that can comfortably handle your peak demand with at least 20% reserve capacity. Proper sizing prevents both overload shutdowns and unnecessary fuel costs.
Will my generator start automatically during a power outage, and how fast will it restore power?
If you choose a standby system with an automatic transfer switch, the generator continuously monitors utility voltage. When an outage is detected, the ATS signals the generator to start, stabilize, and assume the load—usually within 10–15 seconds. Once ComEd service is restored, the ATS seamlessly switches back to utility power and cools the generator down before shutting it off. Throughout this process, no manual intervention is required.
