Derek Cole explains why you shouldn't restart your HVAC system after hurricane flooding without a professional inspection first. Debris like tree limbs and water can damage the unit or spread contamination if you turn it on while it's obstructed.

I would get it checked out first. Because when the unit, when we go through a hurricane like we just did, you have debris, trees, limbs, water, whatever could be in the way. You want it checked out by a professional to make sure it's okay to run before you start running it. What has happened previously is people have turned it on, not working or turned on, hear noise, stop it. Now we got a problem. Now we got damage. Because if we would have just removed the tree limbs and the debris from the fans, that wouldn't have happened. You wouldn't have had that problem. But I would make sure it's safe to operate and you don't cause more damage by running it than just waiting to get it checked out.
