While it might be possible for your HVAC contractor to reuse the existing pad for a new condenser, there are several factors that will likely make it necessary to replace it:

1. The old pad is fractured, damaged.
2. The old pad is too small. New condensers often have a larger footprint to accomodate the additional surface area of condenser coils necessary to get the federally mandated higher efficiency rating (SEER).
3. The old pad may not meet the current Florida Mechanical Code standards for wind resistance and elevation above ground. Here’s the applicable code citations:
   
   
   
       The level of wind resistance necessary is based on this Florida Wind Zone map. So the further south you are in the state, the more hurricane reistance is required:
   
   
       New pads are manufactured from concrete or plastic specifically to meet the wind resistance requirements for both the pad itself and the mounting of the condenser to the pad, which may even require ground anchors below the pad. So, essentially, it’s not simple anymore, and very likely that a new condenser will need a new pad.
