"Our furnace stopped working in Oswego, IL on a night that dropped below freezing. I have two young kids and was panicking. Called JG Cool HVAC, got a real person immediately, and had a technician at the house within 45 minutes. He fixed a cracked heat exchanger, was completely upfront about the cost, and the house was warm again before bedtime. Absolutely recommend."

"Signed up for the JG Cool HVAC maintenance plan in Oswego, IL after a bad experience with another company." Every visit has been thorough and the technicians always explain what they found and what condition the system is in. This past spring they caught a refrigerant leak before it became an emergency. That proactive catch alone was worth the entire plan."

In 1833, William Smith Wilson, his wife Rebecca, and his brother-in-law Daniel Pearce moved to the area now known as Oswego. The land belonged to the local Potawatomi, Ottawa, and Chippewa tribes, but the United States government removed the Native Americans when the government started surveying the land along the Fox River in Kendall County. In 1842, the federal government placed the land for sale at an established price of $1.25 an acre.
