About Frankfort, IL
With a current population of 19,166, Frankfort was founded in 1855. This area was originally inhabited by several Native American tribes, including the Potawatomi and Sac and Fox tribes. In the eighteenth century, French fur traders made their way into the area, along with earlier pioneers of English, Scottish, and German heritage. Today, Frankfort has a charming historic downtown area with unique shopping and dining opportunities. Meanwhile, the Frankfort Area Historical Society hosts many fun events, including a Fall Festival and an annual Candlelight House Walk.
Not only was Frankfort named one of the top 12 safety communities in the state, but in 2016, it was also named as one of the top 10 communities for Illinois families. With so much to recommend it, we truly believe that Frankfort is the place to be.

My water heater went out and needed to be replaced. Called Climate Control Systems and they came out the same day to see what was needed. The next morning they came and replaced my water heater! The guys did an amazing job! Service does not get any better than this!
