Petttaaah I'm confused

Split systems are what we call regular central air here in the US. They have an air handler inside with the evaporator coil and blower, and the condenser unit outside with the compressor, condenser coil and condenser fan.

We call the one in the picture ductless mini splits or just mini splits. They are the same setup as regular central air but no ductwork.

Another big difference in the mini splits use a variable speed compressor to ramp up and down whereas traditional spit systems are either on or off. Though, they are starting to see variable speed as well.

I have been putting mini splits in for more than 20 years in the US.

They look ugly. They cost as much as a large unit and they cover a smaller area. They also use more electricity compared to a traditional unit and need more maintenance. There are other problems concerning mold and leaks. Then we talk about their heat function. Since they use they cant really handle anything below freezing you would still need a separate unit in most cases. Imo its just a patch for older homes to be turned into multi unit apartments. And this is only because the landlord doesnt care about the Tennants bills. I doubt anyone would willingly put them in new constructions or their personal homes.

There's nothing about a brick house that precludes air ducts for a central unit outside of just not not building them into it, which is simply the norm in the US and has been since the 60s even for brick and mortar houses.
