Why did I see no mini splits in the south ?

I have lived up in the Northeast all my life. I am pretty familiar with most HVAC/heating plants though I don't do it professionally. Last spring I researched and installed a mini-split mostly for cooling. but it has some heat capabilities as well.

On a recent 5 day trip to So Florida, I don't think I saw ONE mini split system. Apparently they are not that popular down there.

I am wondering if there is an explanation for it. Temps and humidity too high for too long? Capacity ? Regional energy costs? I thought perhaps it was because most of the existing buildings were built with ducted systems and it just made more sense to continue with them when upgrading, but I saw newer structures as well. No mini-splits. Just curious.

Any thoughts?

Thanks.

    I think they just prefer ducted AC.

    Mini splits are very common in Mexico, at least they are around Mazatlan, Tepic and Guadalajara

    Florida has had ac since Willis Carrier started squeezing refrigerant back in the early 1900s. Well, maybe not that long, but it’s been a while. In the north, ac was not an expected feature, our standards simply escalated. Naturally, adding ac will be more prevalent in the north.

    I know that when I was in Brazil like 10 or more years ago I saw many mini splits . Strangely enough I noticed quite a few older abandoned ducted systems with duct work exposed and done nicely not hacked .Just left in place and multi mini splits installed .i would image aside from the initial costs on updating and replacing the original systems the operational cost would be the lowest w mini split. I have seen them in shops in open multi floor malls ,banks and larger food stores it was eye opening to where you don’t even notice them .i think where a little to slow to change on some fronts which may not be a bad thing.. Personally I would take a mini split any day over breathing in fiberglass duct board systems they do down south or any place ,but hey that’s just me . I’m quite sure on the commercial side the building must have a ventilation capability to evacuate the system charge if a leak where to occur I think a lot of large vrf systems squeeze by with out any body even giving it a thought until there’s a issue ,that’s why years ago there where a lot more chilled water systems instead of direct cooling systems Peace and good luck clammy

    In my part of the south (VA) we install them regularly. So do several other, if not most, HVAC contractors.

    They're used exclusively in the Middle East and Asia where it's extremely hot and humid. I've stayed in 100 story hotels in the Philipenes where heat and humidity can be unbearable. Guess what they had: mini splits!

    IDK why you didn't see them in Florida.

    OMG on that hvac hack ,how do you clean them start from the top and let it drip .i get calls to install mini splits but in a lot of the cases there just looking for low ball prices and usually low ball prices don’t come w any type of quality or fore thought just get the money ,get done and get going the 3 mantras of hacks and possibly block the customers number . A lot of the mini splits I see are non maintained never cleaned and the outdoor is usually setting in 6 inch of mulch and lopped sides still working though.i set them all on stands on concrete lentils on compacted gravel . As my motto goes the sweetness of a cheaper price is often forgotten with the bitterness of poor quality peace and good luck clammy ps thanks ratio for the pics

    Holly Molly. I've never seen so many on the side of one building before. I Wonder what the added weight of those are?
