Oak Park is home to the Frank Lloyd Wright Prairie School Historic District and the largest collection of Wright-designed buildings anywhere. Its historic homes often rely on radiators and boilers and have limited room for ductwork, so we specialize in careful boiler service and ductless systems that add cooling without changing the character of the house.
