Across Southern Maryland, generations of businesses and homeowners have trusted SMO Energy for all their heating and cooling needs because we treat them like family.

The Values of SMO Energy

When Jim Wills and Harold Swann formed Southern Maryland Oil (SMO), they did it with the intention of providing courteous and efficient service, which later served as the basis for our core values. The six service values that guide our team are:

At SMO Energy, we are passionate about what we do. We love helping our customers, whether it’s ensuring their home is heated, assisting them during an emergency or consulting with them about transitioning from heating oil to propane.


Anyone can provide a service, but our goal at Southern Maryland Oil is to make it seamless. From installing a new propane appliance and heating system to delivering your heating fuel, our team makes the process hassle-free.


No matter the weather or day of the week, our team always greets you with a smile. It’s another way we help you feel a part of the SMO Energy family and remind you that we value your decision to choose us from all the other Southern Maryland oil companies.

Our signature value is treating you like family. As a family-owned business with roots in the Southern Maryland community, we feel a connection with the families and companies throughout the area, especially when we’ve been serving them for generations.
