    throwing the compressor off isn't a good idea either. I knew a guy that threw a 5 ton compressor off the back of a McDonalds and when it hit it sprayed oil all over the side of the building and bushes.

    You're no fun. Just leave that oil in there, seal up the suction and discharge, and toss it over the side. But first make sure you heat it up with the torch for a good minute after you seal it up. It'll be just like tossing a big oil-and-shrapnel filled water balloon.

    For years I carry a towel which I roll up and place between my lower back and the seat and it help greatly.

If you're lucky enough to have an RTU close to the edge of the roof, you can attach a single-sheave pulley to it to use this method. After you've pulled out the old compressor, you place it on the edge of the roof, attach one end of the rope to it, run your rope through the pulley, attach the other end to the compressor on the ground. If you're swapping like-for-like, then both compressors will balance each other out to where you hardly have to exert yourself when you pull the compressor up. Even if you have a slightly different compressor, you only have to lift the difference in the weight between the two. As you pull the new compressor up, the old one gets lowered to the ground. And since they both weigh the same, you can just stop to take a break whenever you want and leave them hanging mid-lift. I've done this with hermetics up to 6 tons with no problems.
    I'd like to know more about this pulley system. So if you're on the roof of a house, which typically the unit will not be near the edge...How do you set up the pulley? I know sometimes our guys end up having to get them up with out any help or crane. But if it is a heavier compressor, then usually one guy pushes it up the ladder while it's still in the box, there is a rope tied to it also with another guy on the roof pulling as well.

    I once dropped a 2 hp copeland semi-h off a roof of a mall. It hit the grass and just dissapeared, just a mud spot in the shape of the compressor was left. Its probably still there.

    Thanks for the tip about the towel. I service things as far as 6 hours away in a 2006 Ford with 200k on it. My lower back is just about shot from it. We run service vans to about 300k. They look like crap.
