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.

  • Climate Control Systems has been our "go to" company for over thirty years in two different homes. We have, therefore, used a great many of their services, from boiler installation in a 100 year old home to current updated HVAC systems in our present home. Repairs as well as replacement of HVAC equipment are done in a timely and professional manner. Paul just serviced our furnace yesterday, and was thorough as well as honest with us about the condition of our now aging unit and what to expect. This helps tremendously in future planning. We have the utmost level of confidence in this company, and recommend Climate Control to friends and family without hesitation.
