Packaged Rooftop AC Units

Rooftop AC units or “RTU’S are configured all in one condensing and evaporator units for roof applications. The picture on the right shows an RTU with side flow supply and return air flow connected to protruding duct work.

These are mainly used on commercial buildings but can be used for residential applications as well.  These units are the same type used in mobile homes where central air “split systems” can not be used do to construction restraints.

If they are used for residential homes, the FPL rebate program does apply. Efficiencies start at the minimum of 14 SEER and rise from there. To qualify for the FPL rebate the SEER rating must be above 14 SEER. The higher the rating the more rebate increases.

Commercial Rooftop AC Units

These type of Air conditioning systems are used strictly for commercial building applications. The duct work is attached  to the bottom of the unit. ( both return air and supply air ) They are set on top of a curb, or curb adapter.

These units are normally much larger in capacity than residential package units. The capacity of cooling is measured in tonnage for the particular application square footage. For new installations a heat load calculation is used to determine the proper size.

Only trained professionals can properly determine the correct tonnage for the particular building. Many things must be taken in consideration before the size of the system can be made.
