Mini Split Ductless AC...Anyone have any experience with these systems?

I'm thinking of using one to help cool my bonus room over the garage which is always hot.
I'm either going with Mitsubishi or Fujitsu as I think these are the best brands. Advice appreciated.

My parents have the Mitsubishi, and it's great. Talked my friend into putting one in his sunroom, and he loves it. Super quiet, efficient too.

We use a Mitsubishi Mr.Slim in a few of our server closets..So far so good, keeps the room around 70 or so

Got one in my office, it's awesome, I love it!

Can anyone explain the installation process for these units?
Is it just a fancy version of a window unit? My thought is it sits on the ground, you punch a hole in the wall for the vent to mount and you run a line to a power source. Is that about it?

You run copper lines for the refrigerant to the inside unit.

Had one in the house we stayed in while in St John, works great.
Thinking of putting one in my garage if insulating the door doesn't work.

No, the inside unit is a combination evaporator coil and air handler, it can be mounted on any wall, a set of refrigerant lines and a power cable are run to the compressor unit outside. The system can be sized where one outside unit can support multiple inside units. The design eliminates the need for ductwork, making it simple to add to existing structure, and if multiple units are installed you can have greater control over the temperature in each room.

I have one at my house cooling a single upstairs room. It's about 250 sq/ft. Love it. We only turn it on when the room is in use and it cools the room in no time.

you and Napolean both forgot to mention plumbing for the drain

i just read somewhere that Friedrich is now marketing a diy version that has simple plug-in wires and tubing. no need for professional installation

Will a single wall unit distribute air to multiple rooms? I'm thinking about putting a bathroom & closet upstairs in close proximity of the unit.

Been looking at one for our sunroom. They come in 110-220 for power. I am likely going to have one i stalled next spring.

you can run multiple evaporator (inside) units from a single condenser (outside) unit.
Posted on 8/12/14 at 10:58 am to piratedude
Multiple indoor units off one condenser are call VRF systems.
These type of systems can eliminate the need for extensive ductwork, and give the ability to have multiple temp setting within the house, and allow u to turn of area not in use.
Though u definitely need a pro to install these. One who has taking a VRF class from the manufacturer.

Why would anyone use traditional duct work instead of this even in new homes? Cost for multiple units?
Posted on 8/12/14 at 11:14 am to uway
I just installed one in my bedroom. I drilled a 3" hole in the wall for the copper lines, drain tube, and wiring, then I mounted the bracket and hung the blower. I ran a dedicated 20amp 110vac circuit to the compressor unit that sits outside. I had a local HVAC company come out and connect the tubing (I didn't want to be responsible for putting a kink in the tubing). They pressure tested, vacuumed the line set, and released the precharged refrigerant. Works great, it gets cold in the bedroom now. It's also way quieter than a window unit. BTW, it's a 9000 btu unit with a heat pump. Hope this helps.

I'd much rather have just a vent in a room than that big evap unit. Although, for "not a new" house, I can see where they'd be ideal. But wouldn't you have a big, insulated freon line running up the side of your house? I guess you get colored foam insulation to match your house.

Well for one you'll have one of these units visible in most rooms of the home.
