Mr. Volt Inc. installs Cummins, Generac and Briggs & Stratton homeowners and businesses throughout Chicago, Willow Springs, and the greater Chicagoland area. Because we sell the units we install, you get equipment sizing, electrical work, and permitting handled by one team instead of coordinating between a retailer and a separate contractor.

Chicago-Area Permitting
Generator installs in Chicago and most collar suburbs require an electrical permit and, in many cases, a mechanical permit for the gas line. We handle permit submission and inspection scheduling as part of the install so you're not tracking down inspectors yourself.
Common Questions
How long does installation take?
Most residential standby installs are completed in one to two days once the unit and permits are on site. Commercial jobs are scoped individually based on panel work and site conditions.
Do you install generators I didn't buy from Mr. Volt?
In most cases yes, provided the unit is a supported Cummins or Generac model. Call to confirm compatibility before scheduling.
What's the service area?
Chicago, Willow Springs, and surrounding DuPageCounty suburbs. Call for confirmation on locations outside that radius.
