Condensing Gas Rooftop Units

Condensing gas rooftop units (C-RTU) are becoming more available and popular for commercial buildings where high efficiency and lower operating costs are attractive benefits. C-RTUs provide a big upgrade over traditional gas furnaces providing 10-15% higher heating efficiency and up to 11.5% reduction in gas energy usage.
