Thank you for your question on the model 654H housing only. It is easier to remove the housing if you have attic access. The housing is normally attached to the ceiling joists with screws or nails, so having attic access with make the removal easier. If you do not have attic access, you would need to enlarge the hole around the housing so you can work around the unit to detach it from the joists. You will also need to be able to reach the duct work and wiring so enlarging the hole should allow you to do this. You may have to patch the ceiling afterwards depending upon the size of the new fan you purchase. If you have further questions, please contact our Technical Support department directly at 800-637-1453.
