ABOUT SMO ENERGY

With over 90 years in the industry, we continue to be a progressive heating and cooling service provider, while remaining true to our core founding principles, rooted in excellent customer service.

Our History Service Locations

A Family Company that treats you like Family

Our commitment to industry leadership began in 1926 when two ambitious men, Jim Wills and Harold Swann, acquired the La Plata Oil Company and Mechanicsville Oil Company, and merged the companies to form Southern Maryland Oil Company (SMO). The newly formed company distributed products and pledged “courteous and efficient service.” In the early days, Southern Maryland Oil handled only three Texaco products: kerosene, gasoline, and motor oil. But by 1937, with the invention of the gun type burner, fuel oil became a hot commodity and created an ever-increasing market for home heating. SMO began deliveries on an automatic basis – the first such service available to clients in Southern Maryland.

Core Service Values:

    • Be Open and Honest
    • Work with Passion
    • Ensure Seamless Service
    • Deliver with a Smile
    • Go the Extra Mile
    • Treat Our Customers like Family

Southern Maryland Oil founded in 1926

The founders had no idea that SMO would grow into the largest business of its kind in the region – let alone one of the largest family-run businesses in the state. The only dream for SMO was to be recognized for great customer service. And now over 90 years later, the company’s founding principle of customer centricity is a continued hallmark that can be observed in years and decades of continued service and repeat clients.

Throughout our 90 years, we have diversified into other areas of operation along the way, under our parent company, The Wills Group.  Our sister companies include Dash In convenience stores, Splash In, and SMO Motor Fuels, which serve gas stations and commercial clients across the region.

We are proud to be a locally operated and family owned business rooted in Southern Maryland. We provide high-quality products with “courteous and efficient service” and we look forward to serving our clients for many years to come.

Friendly and Helpful Delivery Service!

The SMO delivery driver was very courteous and professional. I always find SMO delivery drivers to be very friendly and helpful. They take the time to explain things and address any questions that I may have.

Service by Professional and Reliable Technicians

I happened to be home when the driver pulled in. I went out and chatted with him. Really nice fella’, asked him a couple questions about the oil and my tank. He was helpful and pleasant. My service tech, Mike, lives in my community. When he came for my annual furnace checkup, I felt he was very knowledgeable and kind. I knew if I needed any service or my furnace had issues, he would be there for me!

A Service with Extraordinarily Kindness

The wind had taken some recycling items and scooted them away from the end of my driveway. The driver was extraordinarily kind to scoot them back as he passed by. Happy to be able to let you know of his kindness.

28 Years of Professional and Personable Service

We have relied on SMO for more than 28 years to see to our oil needs. The service has always been excellent both by the fuel delivery drivers and the service technicians who have cared for our furnace and air conditioning over the years. Always professional and personable at all times. Thank you very much.
