The clergy of First Assembly of God Church in Shrewbury reached out to Dr. Energy Saver to help solve their comfort issues above their rectory. Dr. Energy found their ducts were not getting the air to the conditioned space because of all of the air leakage in the ducts. They felt the ducts were blowing in hot air instead of the conditioned air that is supposed to come in. By encapsulating the ducts with 2" polyisocyanurate foam board and sealing it them with closed cell spray foam Dr. Energy completely maximized the efficiency of the duct system. Maximizing the efficiency of the duct system ensures that no air will escape and all will reach the conditioned space keeping the occupants comfortable.
