"Heat went out in Millstadt, IL at the worst possible time." 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."

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.

During a barn raising in 1836, it was proposed that a town be incorporated on land belonging to Henry Randleman. The name "Centerville" was proposed, as the site was equidistant from Belleville, Columbia, and Pittsburg Lake. The town was platted on March 13, 1837. In 1880, its name was changed to Millstadt, as the name Centreville was in use by another nearby town.
