Working at Florida career college in Hialeah one of our many valued commercial customers. Customer has an office that is very warm. Found that room was warm due to supply grill for the room being a blank supply meaning it was not connected to the unit. Also found that actual supply drop that was connected to unit was above drop ceiling. Removed blank supply and put actual supply drop back in. Unit is now providing proper air flow to the office and we have a very happy customer.
