Generator Installation


Do you have flood insurance or can you get flood insurance?  Do you have sensitive medical or computer equipment that will be compromised in the event of a power outage?

Consider an automatic back-up power source for emergencies. Homes are extremely vulnerable to flooding when power outages knock out our sump pumps. Not only is a power outage inconvenient anymore, it can be downright expensive. Power loss can also effect the elderly and home-bound relying on electrical medical equipment.  More and more people are working form home and/or have home based businesses.  Losses in power for those people may mean a loss of productivity and of income.

We’ve been helping home and business owners with reliable power solutions in the greater Chicagoland and Southern Wisconsin area for over 19 years from our brick- and- mortar office/warehouse in McHenry, IL. We also provide yearly maintenance to keep generators running at their prime.
