Determine the duct sealing man-hours will base on the linear footage of current ridged ductwork and prevailing duct insulation.
- 4 Man Hrs. (un-insulated rigid ducts less than 200 liner feet.)
- 6 Man Hrs. (un-insulated rigid ducts greater than 200 liner feet.)
- 8 Man Hrs. (insulated rigid ducts less than 200 liner feet.)
- 12 Man Hrs. (insulated rigid ducts greater than 200 liner feet.)
