What mechanisms are used to hoist a HVAC unit on a roof? How do they work? Where can you purchase them? Is it really true you can make your own?
Well, when I set a package unit or a condenser on a roof, I hire a crane to lift it up for me. The crane guy we use charges about $150 per hour, 1 hour minimum to do a job here in town. Once you think about the insurance and upkeep expenses he has, it really is a bargain. Possum, HVAC guy
