What is a split system?
A split system separates the equipment into two parts. The condenser sits outside, and the indoor blower, furnace, or air handler sits inside. The vast majority of homes use this setup because the indoor unit can be centrally located for better air distribution through the duct network. Split systems also give you flexible matching of a condenser, coil, and furnace to fit your comfort needs.
What is a package unit?
A package unit places the cooling and heating components together in a single outdoor cabinet. There is no separate indoor furnace or air handler. Conditioned air travels through ductwork that connects directly to the cabinet. This design works well when indoor space is limited or when an indoor furnace is not practical.
When does a package unit make sense?
A package unit is normally used for homes on an elevated crawl space, for mobile homes, for rooftop installations, or anywhere that an indoor furnace is not desirable because of space or closet limitations. Mobile homes in particular often rely on package units or specialized mobile home equipment because interior square footage is tight.
Quick comparison
| Feature | Split System | Package Unit |
|---|---|---|
| Indoor unit | Yes, blower or furnace inside | No, all components outside |
| Best for | Standard homes with closet or attic space | Mobile homes, rooftops, tight interiors |
| Air distribution | Central indoor blower for even flow | Air feeds from one outdoor cabinet |
If your home has room for an indoor furnace or air handler, a split system is usually the better fit. If space is limited or the building is a mobile home, a package unit keeps the whole system outside and frees up interior room.
