Measure up coils legenth width height fins/inch #of tubes and tube size and call a coil manufacturer for a rating. You may find the original name tag if you look around Sounds like they let the place go--now they are paying for it with high fuel bills--nothing wrong with steam or pneumatic controls -but they need to be maintained
