I live in the third world too, all remote controlled AC here, too. In the US, that's unheard of (at least to me.)
Most other countries make more use of using Mini-split HVAC units. Here in the US Central HVAC is more common even if it uses more energy (and you have to heat/cool everything instead of just certain rooms like you can with mini-splits, and no duct to lose the temperature in a mini split)

You can get more standard vent looking mini-splits but they aren't as common

Yup. It actually works amazingly well down here where the heat never stops.

It's definitely seen those too, but you are right, it is rare.

We had two of those at a previous job. They worked amazingly well on warm-hot days... didn't work at all during the winter, never figured out why.

We have a mini split in our on-site DC. It has gone out 4 times in 8 years and been replaced fully once.
At this point in time I have a hard time trusting them.

This looks more like an RV style AC vent than a commercial install.

That's like saying your server died so you don't trust servers. Don't mix one model or vendor being unreliable, and especially not one specific unit and probably an individual installer, with a category of things. If you look at a Pinto, cars seem unreliable. If you look at a BMW 750i, they seem to never break. It's not that they are "cars" that defines their reliability but the maker, model, instance and maintenance on them.
-
yeah yeah I know... I'm on my second one... and second vendor (Carrier this time) and similar issues.
I know this doesn't mean the whole idea is bad... I'm simply frustrated by these that I've personally had experience with.
-
Carrier? After being in the Carrier Dome which they cannot air condition, I've never felt good about them. If they can't cool their own facility, why would I trust them? Never use someone that doesn't eat their own dog food.
-
Samsung and Frigidaire are the big players here.
-
HVAC performance is just as much about the skill of the person installing and maintaining it as it is the brand of the unit. HVACs are suppose to be checked every 6 months. a lot of failures are from low coolant levels over time causing failure.

Superisingly I've had better results from the cheaper brands like Heil/Goodman than I have from expensive brands like Trane, Carrier, Lennox, York etc.

Our units were Hitachi.

Is it weird that I don't think of any of those as "good" or high end brands but as cheap American made stuff? AC is not something that American made sounds like quality to me outside of Frigidaire. Those are feel like consumer brands as opposed to the big enterprise makers.

Trane is probably one of the most popular in american enterprises. Mostly because people get sold on the Tracer Summit automation rather than how the HVAC functions itself. Luckily we didn't.

I'm pretty sure we use Liebert here. No opinions one way or the other.

Quite common in Mexico as well, we are using Mirage currently.

Liebert Makes HVAC? I think ours datacenter one might be too. Never looked at it much it's in a separate room. I do know it's not a normal HVAC in the sense it does not only ducts. It uses water pipes to heat/cool the air. We do have very large Liebert NX 3 phase UPSes though. They are nice.
