About Us
Mission Statement
From the very beginning our mission has been the same:

Our History
If you want to know how a good company got to where they are today, look no further than their roots. Our story begins in 1956, when James Leonard & Charlie Splaine moved from Milton, MA to Woodbridge, VA. Upon arrival they started a gas station with 2 service bays and a truck which they used to deliver home heating oil to the local neighborhoods. And just like that, the Leonard Splaine Company was born.
In 1972 they started installing and servicing Oil Furnaces. Over the next ten years they continued to expand their product offerings to home and business air conditioners, gas and oil furnaces, and heat pumps.
In 1982, two of James’ sons, Gary and Tom Leonard, took over management of their father’s life work. Within the first year, they built a 5600 square feet office building and warehouse to replace the original service station. The third generation began learning the family business in 2004 and the future continues to be bright. Although the company has evolved with the care of each generation, the company maintains the ethical foundation that it was built on. We hope to continue to serve our community for at least another 50 years and beyond.
