Mini split ceiling cassette experience?

[jpcjguy]

Hey all,

Thinking about converting some of this upstairs space on my detached to a home office which would include getting a mini split for it. I assume the end wall (opposite of the door) would be the only place for a wall mount, which I am not loving. That leaves a ceiling cassette option - Mr Cool has a 12k version and I wonder if it is too big for the space? Room is roughly 31x14x8 with 5'5" high knee walls, so about 400 square feet? The ceiling/slopes are insulated well. I did a 1.5" air gap between the trusses using wood spacers and fit some foam board between that was sealed with expanding foam. (what started as a great idea, ended up being a PITA - but I followed through!)

Does anyone have experience with ceiling cassette? Not loving the price but probably my best option...

I currently have 4 LG 12K ceiling cassettes installed 8 years ago and are working.

The cons are they are big in area to look at (so don't look at it) and seem to be slower to cool due to the round fan assembly as opposed to the wall mounted cassettes using squirrel cage.
And the condensate is removed via a pump as opposed to gravity on a wall cassette.

good feedback thanks! did not think about pump and fan speed....

I was faced with a similar decision in a less than ideal shaped room. This is our FROG (finished room over garage) we use for a guesthouse. That’s a 18K Mits floor standing unit. It actually mounts to the wall. I keep two ceiling fans running in reverse to distribute the air evenly. I can keep the (spray foam insulated) room 70* even on the hottest Texas summer days. It could be worth a look.

ETA; or just install a wall mount as high as you can on the 5-1/2’ wall(s)

As to a possible floor standing unit....

Have 2 floor standing Fujitsu units in my large living room. Quieter than the high wall mounted units. I embedded them in the stud cavity so only 4" shows, more esthetic and less noise than high wall mounted units, a little less energy efficient though . Agree leave room under them for floor covering and cleaning. Lines and drain can be mounted out the back, drain is gravity type, no pump.

I installed a Pioneer 12k unit last year in my kitchen/dining room/family room project. Dimensions on my room are similar to yours at 45 x 14 x 7' 9". So far, it is working well, it just took some familiarization with thermostat settings and air flow patterns.

Because the air output is all around the unit and the room is MUCH longer than it is wide, I have installed (temporary) restrictors to direct more air to the longer areas. That has helped considerably.

Looking at your pictures, you may have to move some of your insulation to provide access to install the unit and run the refrigerant and drain lines.

When ordering, don't forget to allow for the extra length in the refrigerant lines.
