Our Services How Can We Help You?
Founded on Honesty, Reliability & Professionalism
Cardinal Heating & Cooling was established in 1991 by HVAC industry veteran, Nelson Workman. After 35 years of working for different HVAC companies, Nelson bravely pursued a lifelong passion of opening his own company together with his sons.
Right from the start, Nelson has set very high standards for the company, emphasizing the core values of honesty, reliability, professionalism, and respectability. In a short amount of time, all of the family’s hard work and good intentions eventually cemented Cardinal Heating & Cooling’s reputation as the most trusted HVAC service company in Herndon, Ashburn, and all of Fairfax and Loudoun Counties.
After Nelson’s passing, his son, Tod Workman, took over and is now personally overseeing that his father’s legacy continues with the high-quality services and products the company offers.
