Church had very old HVAC systems and the cooling was not reaching multiple locations far away from the source of the AC in back of church. Church retained Largo Green, Inc. (LG) to analyze, design, & implement a solution.
After several site visits and calculations, LG determined the extra long trunk line in the attic was significantly undersized. Additionally both the HVAC systems feeding those trunklines were under performing.
LG recommended upgrading bot the HVAC systems with higher SEER, gas, up=flow systems. The ductwork & trunklines were redesigned to capture much more air pressure in order to reach the front of the church. New ducts were added as well to distribute the cool air.
