As the largest energy consumer in the United States, the Department of Defense is always looking for energy-efficient technologies. So when Fort Dix ordered 2,000 units of a new type of heating system, I took special notice of the brand. I can see why they chose them. Using patented technology, the Acadia heating system can provide savings of up to 70 percent over other conventional systems. Way to go, Uncle Sam! The Acadia is available for residences and can be installed by any experienced HVAC contractor, no special training required.
