Our Story
Winter was founded as an electrical contracting firm in 1947, doing construction projects as well as industrial trouble shooting and maintenance. During the contracting years, many standby power systems were installed and placed into service. This identified a future market and Winter Engine-Generator Service, Inc. was established in 1964 as a generator distributor for central Pennsylvania.

This is our legacy.
The Winters are part of a well-known family in York County, PA, with a deep-rooted history tied to the local agricultural and manufacturing community. M.L. (Martin) Winter was a technician at the Flinchbaugh Manufacturing Company in York, famous for producing "York" gas traction engines and tractors. M.L. Winter is widely known among engine historians for preserving and documenting the early history and catalogs of engine origins at the Flinchbaugh Company. Ralph Winter, our beloved founder of Winter Engine - Generator Service was M.L. Winter's uncle. As you can see, this work runs in our bones. With several "Winter" names still present in our directory, you can see it's not just a career. It's a legacy.
1973
In 1973 our service area was increased to include northeastern Pennsylvania and the Poconos. The company sold and serviced on-site standby emergency power supply systems to public buildings, utilities, hospitals, health care facilities, schools, churches, water and sewer, commercial, and industrial applications. Attention was also given to residential, recreational vehicle, and marine generator sets.
1989
In 1989 Kohler Power Systems appointed Winter Engine the factory authorized distributor for Central and Eastern Pennsylvania. Winter has the facility, personnel, experience, and capabilities to provide a wide range of products and services. Constantly in pursuit of quality and reliability, we have a staff eager to take on new challenges and opportunities.
