    one of my clients recently had their insurer come through. they have indicated that the building is now in a hurricane zone or some nonsense, and claim that the rooftop units are not properly strapped in for hurricanes. ok, building is roughly 22 years old, packaged yorkies, nothing special like 25 tonners or something. since this area doesn't typically see that specified, I literally have no idea how to fix this. do we just strap the rooftop to the curb, or add guy wires laced into the building steel or what....

    help

    In Fl we strapped to the curb, if was a unit sitting on a bench attached to the iron we would use aircraft cable and tie it to the bench

    What does the insurer want, what does FEMA require in that area?

    Trenton is a tornado zone, believe it or not.

    When I used to work up there we strapped them to the curbs.

    The bigger units, meaning 100 tons and up would get welded down to their supports and tied into the structural steel with cables.

    100 tons??? At that size,You'd think they'd Help hold the Building in place, during a Tornado.

    Strap them to the curb so you won't need a curb adapter if a storm is strong enough to blew said unit off curb

    Down here we use Hurricane clips, screwed into the inside of the curb and the outside of the rail on the unit. Other than that the units are lagged into the curb through the rail

    Can you put something heavy on top of each unit? Like a brick or something?

    Seriously,what if somehow they were tied down with Steel Cable that ran down into the Building through the Duct,and got strapped to the Building's Framework? Now it going anywhere without the Building in tow.

    That just insures that they will get new duct work with the new unit and roof

    yea but those are usually nice steel channel base rails an set on I beams so its simple, just run an inch of weld every few feet. I think if you put any heat to a York unit base rail it would fall apart.
