ABS ??
Assuming he needs a small amount of room to work, he grabs his tape measure, finds the position he wants, goes downstairs and using his tape measure finds that piont on the cieling and then cuts a hole the correct size for a snap in vent to fit back in after working. As i said at the begining ABS ?? but it is possible to get a working space ina cieling the way i discribed above without removing the whole ceiling
