Hi Jeff. Wayne is correct... I just wanted to add some information to help you do your research. Cook County: www.cookcountyassessor.com and www.cookcountytreasurer.com - the first to find the amount of your current assessment and the second to learn if the property is enjoying any exemptions- homeowners or seniors, for example.
Electric inquiries ARE with ComEd- 1-800-EDISON-1.
Gas inquiries ARE with NiCor- 1-888-NiCor-4-U.
I hope this helps a little... (smile). Good luck, Jeff.... more
