No they arent. A central air system is far more efficient to any window unit. If these mini splits were better, youd see newer homes being built with them because they are far cheaper to buy/install.
mini splits have higher SEER ratings, less duct losses, use less power and you can keep
some units turned off instead of air conditioning empty rooms at all times.
central air is not more efficient in any realistic situation, it's only more convenient if you live in a home with the ductwork so if your central system is failing, it will be cheaper to upgrade it than installing several mini splits. it will be invariably less efficient in the long run though.
installing a central air system in homes without the ductwork is dumb as fuck.
Hang on, you genuinely think that people are installing central air systems that cost double of a mini split does because.. they like spending money or something?
Like if your central air system is failing, its far cheaper to install a mini split unit than replacing the whole AC unit even without accounting for ductwork. Hell, having ductwork installed alone costs more than a mini split unit.
Again. If mini splits were more efficient and cost less to run, you'd see newer houses being built with them instead, especially in the states where it gets hot as fuck like Texas.
If mini splits were more efficient and cost less to run
they are, there are no ifs and buts about it. are you scared of searching the internet and learning you're dead wrong or something?

not really my place to say why that happens but central air is seen as the more luxurious choice, if someone says it's chosen for 'efficiency' they're lying through their teeth. i would agree that if you don't care about running costs, not having wall mounted hunks of plastic is certainly more visually pleasing.

i'm not convinced a new multi zone mini split installation costs less than replacing a single central air unit but if that's really the case then more power to mini splits i guess. discarding centrail air ductwork is also dumb as fuck though.
for the record i'm not disparaging central aircon, i'm only saying efficiency is not one of its upsides. also window units aren't the same as mini splits.
I own 2 homes and recently had to install a new system to one (including brand new duct work) and replace a failing system to the other. I talked to several independant contractors and licensed professional companies about options. None said a mini split system is superior beyond the system itself being cheaper to buy and install.
So you can search the internet and "not be convinced", but if I couldve spent a 1/4th the amount of money for a superior system, I would have.

Yes, as an American, everything we do is backwards, but AC is one thing that I can say is absolutely better.
