Meet Mark Dickerson
After more than a decade of seeing the poor standard practices of some other heating and cooling companies, Mark Dickerson decided to do things differently. He founded Mark's Heating and Air in 2012, initially working evenings and weekends before transitioning to full-time in 2016.
The company operates in Sparta, Tennessee, serving surrounding counties and performs residential, light commercial, and new construction HVAC work.
