I have a question as the code is being interpreted between 2 counties as 
different.

We have a condensing unit located on a residential roof 20 years old & 
we changed it out & secured it to the existing timbers. The county the 
change out is in says we must raise the unit to a stand, now on 4x4's. 
Another county says if we were in their county we can put it back where 
it was on 4x4's.

I read the code & understand, we would only raise the unit if the job was:
 
1. New construction or
2. If we were relocating it from the ground to the roof (never been on 
the roof before).

Please set us straight & tell me the truth.

Thanks, Dan
