History of Thornton Heating Service

Thornton Heating Service, Inc. opened its doors in 1959 to serve the needs of Chicago’s North Shore communities. This privately-owned business started by installing and repairing hot water and steam heating systems.

Over the years our strong work ethic and commitment to our valued customers has helped us grow to become one of Chicagoland’s most trusted heating, cooling and air quality services company. A foundation for our success has been the meticulous and careful selection of only the best name brand products in heating, cooling, comfort and safety.

Under continuous ownership of the Starck family since 1974, Thornton Heating Service continues to provide these exceptional products combined with highly-skilled services across the North and Northwest Suburban area of Chicago.
