You see a lot of these split systems on HGTV's House Hunters International. Occassionnaly they pop up on Craigslist here in the desert. Is that some kind of a quick-disconnect between the outside and inside units? If so that seems very unusual, no?
First one I've seen with a quick-connect. That's what interests me.

Cool.
That looks pretty neat.

Those split systems are quite common overhere, aside from portable airconditioners. Window airconditioners and through the wall units are very rare here.
<span style="font-size: medium;">Only thing new is the "quick connect" technology. Split units and inverter technology have been around since the 1980's. I remember seeing them back then. Still relatively rare here in New York. Ubiquitous in Puerto Rico and in Spain. </span>
From what John and I learned at an HVAC show in Atlanta in the 80s, the technology, usually in a heat pump application because of the climate, originated in Japan because of space and construction considerations.
The thing that worries me about them is, as Pete was telling us last year, the incredibly poor filter at the intake of the inside units, not that the situation is specific to these, just made worse by the lack of space in which to put an additional filter.

Not knowing if/that it had already been invented, I wrote a patent outline for 3-ph inverter regulated air 6 years ago. "Method and Apparatus for Demand-Optimized Energy Consumption in Residential Air Conditioning." One part might have been patentable, mounting the electronics in a cold gas return line manifold for reliability.
Other than the motor the compressor was a conventional swash design, the ones that tend to last 20-30 years. Unlike the rotarys they like to sell now. Cheap and compact but design life 5-12 years. I live in an institution full of them, all but a couple have been replaced in the 15 years since the place was built, many more than once. The one in my unit is 4th generation.

Seen these split HVAC systems in older Gov't buildings-conveneint for older places.There are several of these at the transmitter site.And Lots in the Wash DC plant!
One of my clients has two of these in their home to augment their central heating/cooling system. The two rooms are in far corners of the house where it's difficult to regulate temps so these units keep the rooms comfortable without temp extremes in other areas.
Both are LG branded and seem to work very well. Remarkably quiet, too.

This would be perfect for my basement unit.

They say it can also be quickly disconnected and moved. I'm wondering what's involved.

Didn't we have a member here who installed one of these split systems in a tri-level home a few years ago? I wonder how it worked out for them long term?
I've had a ductless split system in my home for about 7 years now. It has worked well and without a problem. I had it installed in the bedroom because I was mainly concerned with having a cool, dry bedroom for sleeping. I have a fan at the bedroom door that blows the cool air down the hallway and into the living areas. On these hot/humid days it keeps the entire house reasonably cool and the bedroom is ice cold.

Might have been me.. Our house is a 4 level split which had one when we bought it in 06 and I replaced it with a new one in 2010. It cools everywhere except the top floor so I've got those two portables up there but really only need one excepton the hottest of hot days. The other thing that helps is that the main floor living/dining/kitchen is all open concept with cathedral ceilings so it can blow the cold air everywhere and it naturally drops down to cool the familyroom/laundry room area. The basement is always cool anyways in the summer and I seldom have to have the dehumidifier down there running.
