Early Years
Deljo’s legacy began when its forebear, Del-Nard Fuel Oil, first set up shop in 1922. Offering complete furnace cleaning and repair services throughout the Chicago area, the company quickly made a name for itself through exceptional customer service and continued to serve the heating needs of its Chicagoland neighbors for the next 60 years, effectively setting the stage for Phase 2 of the brand’s evolution.
Recent History
In the early 1980s, Bob Clement came into the picture, purchasing the highly respected company and taking the helm. The small five-man operation continued the tradition of excellent service that had marked the Del-Nard name over the years. Sometime later, Bob Clement invited his brother Bill on board, and with the team-up, the business flourished. The joint venture that became a cooperative effort between the two Clement brothers gradually grew into the operation that Deljo Heating, Cooling and Plumbing has become today. The company’s early legacy had provided a solid foundation on which to build — and perfect — the necessary mix of HVAC expertise and personalized service that have since come to characterize the Deljo name.
Into the Future
As the company looks toward the future, the brothers who lead it see even greater change and innovation ahead — and with them the opportunity to make the most of emerging new technologies to continuously improve their operation, taking both customer comfort and personalized service to a brand new level.
Deljo – Creating History Every Day
As the Deljo team leaves the office each morning, each technician views their appointments as a new opportunity to build an ongoing legacy of quality through their work.
