What happens when the weight of the AC unit is greater than the holding force of the luggage rack screws? If you and a friend are incapable of lifting the unit onto the roof using a rope, get someone else to get it up there.
Back in the day, I used to hump two bundles of shingles at a time up the ladder and up to the ridge of the roof. The architectural shingles are now heavier and I'm older so it is one 80 lb. bundle at a time.
The ladder holds at least a 250 lb person and the luggage rack is connected to the ladder. The A/C weighs 85 lbs. I weigh 120.
