Company History & Growth

The story began in 1932 with a focus on Oilheat delivery. Over the decades, Approved Oil has grown by listening to customers. They added preventive maintenance, emergency repair, and new equipment installation to become a true total-care provider. To make life easier, they introduced payment budget plans and price protection programs. A major part of their growth came through strategic acquisitions, adding 11 companies over the years to expand their reach and expertise. Today, they stand as one of the largest independently owned residential energy companies in the metropolitan area.

Leadership with Deep Roots

The company's journey is closely tied to the Theurer family. Mr. Theurer started learning the oil business at age 10 from his father, mastering boiler mechanics and repairs after school. Once he got his driver's license, he delivered oil, learning NYC's complex streets and routing firsthand. He convinced his family to let him run the business, and at just 20 years old, he made the company's first acquisition. His hands-on experience from the ground up, from tool work to logistics, shapes the company's practical, customer-focused approach today.
