Package Units System Selection :

• How do I determine if I need a split system or package unit?                        Back

  The vast majority of homes have a split system. These are advantageous because the blower unit can be centrally located for better air distribution.
  
  A package unit is normally used for homes on an elevated crawl space, mobile homes or for roof-top installations or anywhere that an indoor furnace is not desirable because of space or closet limitations.
