Saint Charles, Illinois

St. Charles was the location of the Native American community for the chief of the Pottawatomie that inhabited the area. A city park overlooking the river was dedicated to this Native American past. After the Black Hawk War in 1832, the entire area of the Fox Valley was opened to American settlement. Evan Shelby and William Franklin staked the first claim in what is now St. Charles in 1833. They came back in 1834 with their families from Indiana, and were joined by over a dozen other families later that year. The township was initially known as Charleston, but this name was already taken by the downstate city of Charleston, Illinois so the name of St. Charles (suggested by S. S. Jones, a lawyer) was adopted in 1839. St. Charles became incorporated as a city February 9, 1839 and reincorporated October 17, 1874 (under the 1870 Illinois Constitution).

There is widespread speculation of slavery-era Underground Railroad stations operating in St. Charles homes, complete with tunnels and false doorways. While these claims are not historically substantiated, there was an active abolitionist group operating in St. Charles around this time, called the Kane County Anti-Slavery Society. The Society was founded in 1842 and had about 180 members at its peak. The most plausible connection to the Underground Railroad in the town is the Wheeler House, built in St. Charles in 1837.

St. Charles was a very isolated place early on in its existence. The village was located three days away from Chicago, and the Fox River was not navigable for large boats. By the 1850s, St. Charles had begun construction of a plank road to Sycamore but turned down an offer by the Galena and Chicago Union Railroad to construct a line through the town, which was eventually built in nearby Elgin. Lack of regional connections in the early years kept the town relatively small. St. Charles was without a railroad until 1871 when a branch line from Geneva was constructed, and was without a direct connection to Chicago until the 1880s with the coming of the Chicago Great Western Railway.

Streetcar lines along the Fox River between Elgin and Aurora were built through the city in 1896, operated by the Aurora, Elgin and Fox River Electric company. A direct automobile route to Chicago, which eventually became Route 64 (Main Street), was constructed in 1920. Four Illinois state routes, including Routes 64, 38 (Lincoln Highway), 25 (5th Avenue) and 31 (2nd Street) now run through the city. Two major Kane County roads also cut through the city; Randall Road on the west side and Kirk Road on the east side.

St. Charles was also the place of settlement for diverse groups of European immigrants, including those from Ireland and Sweden during the 1840s and 1850s, and later, groups from Belgium and Lithuania.

exceptional experience
after a lengthy period securing numerous estimates to replace my furnace and air conditioning system, i decided to go with tdh. the decision was made from a combination of price and the knowledge and expertise of mark who provided the original estimate and follow up discussions with tim the owner. the installation went flawlessly and i could not be happier. installers wally, jesus and chris were exceptional. they included me in all decisions throughout the install process. they treated my home with respect and were courteous and very neat through the entire process. i cannot say enough about the quality of the workmanship of this install. it was flawlessly executed and i could not be happier.

Navien Combi-Boiler / Tankless Water Heater System / Unico Air Conditioning System
I wish we would have found TDH Mechanical 15 years ago. We have a old home that needed upgrading. Central Air system, and we discovered we needed to correct our boiler / stainless steel chimney liner. The liner was undersized for the current boiler, which was 15 years old. Tim Hanc met with us and recommended a Navien Combi tankless system. Which will handle both the radiant heat and our hot water for the home. Wall Wojtowicz along with Jorge and Jesus were on the job at 7:00 am to 6:00 pm and finished the installation in one day. Wally and his team were unbelievable, the work ethic they have is unmatched. Any other company would have had their mail forwarded. at least for three days. Wally, Jeorge and Jesus also installed the Unico A/C System, after 30 years of window bangers, we know can relax and finally enjoy. Thank you Tim, Wally, Jorge and Jesus for a Superior Construction Experience with both installations. TDH Mechanical is our HVAC Company of choice!!!!!! :)

Wally did a thorough job, was conscious to keep the area clean, and answered questions I had.
Dave - St. Charles, IL 60174
Very pleased with my mini split/heat pump installation
I got quotes for different brands of mini split/heat pump installation. Each quote stated that it would probably require cutting into the drywall. One even stated they would have to replace all of the pipes behind the drywall. The Mistsubishi mini split/heat pump for my 4 season room fit in perfectly, even though it replaced a different brand. I have some slight touch up painting to do, but no dry wall repair. Wally installed the unit and the work was very professional, clean up was great, and the unit is warming my 4 season room nicely. It is running much quieter than the inside portion of the previous unit did.

Chris went above and beyond his service call to our practice. He was knowledgeable, and showed excellent critical thinking skills. We had birds making a home in our vents and he created a solution to prevent them from coming back. Fees were very competitive and fair. Thank you!

Prompt. Good work.
Diane - St. Charles, IL 60175
Once again, excellent service!
I had a sense one of our furnaces (newly installed) was not always coming on when needed. I thought it might be the signal from the thermostat. When the technician arrived he cycled through the thermostat for me. The settings appeared correct. He then checked the furnace and found an error code. He corrected the problem and explained it to me. Throughout the visit Rolando Carrera was patient, communicated clearly, technically competent and thorough in his work.
Phil - St. Charles, IL 60174

Great job
Roger - St. Charles, IL 60174
Great job
Kris really did a great job for us. He diagnosed the problem right away, managed a temporary fix to get our hot water restored, and then worked closely with the manufacturer to send a new heat exchanger promptly. He then installed it over the course of a day, much longer than he anticipated. But he kept at it until the job was done.
Jeff F - St. Charles, IL 60175
