This successful HVAC addition to the customers’ existing machine shop was a turnkey project that included HVAC, concrete, structural, electrical and controls. We installed 3 large air rotation units, first installing concrete pads then building the units in place. Once in place, large refrigerant piping was run to the condensers. In addition, new VFD’s for roof fans were modified on the existing units and additional boilers were installed to the heating hot water system.
