Advanced Energy Systems

Advanced Energy Systems sells, installs and services home standby generators, working as a licensed Generac and Briggs & Stratton dealer. The company stocks genuine replacement parts for both brands and also handles generator maintenance programs and repairs. It also does residential and commercial electrical work, including EV chargers, recessed lighting, code updates and panel upgrades, through licensed electricians.

Free estimates are offered for generator installations, and the company provides 24/7 service, with after-hours emergency calls handled by an on-call technician. Work covers McHenry, Lake and Cook counties as well as southern Wisconsin. The office is at Highview Street in Spring Grove, and generator warranty repairs are dispatched through the manufacturer's factory-trained technicians.
