A split AC/heat pump is most common in homes with the compressor and condenser located outside and evaporator and blower inside.


A packaged unit has everything outside and just runs duct work to the inside.



If you're building a house, which type would you install?
In general, a split unit cost more to install, but is more efficient in the long run.

I certainly imagine if you are just replacing an existing unit, you'd use the same thing you already have.

I have never seen a package unit in a residential home.

I’d imagine just ducting to and from a package unit would be very difficult and inefficient. Running a line set through brickwork is nothing. Running a 12” or larger duct would just be tough, much less two of them (supply/return). You’d have to enter the wall through the attic space, or lose a lot of interior space to route the duct through the wall.

The heat loss/gain of the duct work, plus balancing the system with a long header run vs a centrally located blower with independent branches.

Package units are ok for a trailer house, but I would never put one in a new house I’m building.

We have a package unit for downstairs. Have a large crawlspace so it makes sense. Honestly the only downside for the package unit IMO is that they are not as efficient.

Look into Ductless Mini Splits also.
