thatās awfully high, I built my cellar two years ago and paid about $8k for a WhisperKool 8000 ductless mini-split (ceiling mount) - googling, looks like they havenāt moved in price since.

400 sq ft. I have double baton insulation. Corner of the house in the basement, so two exterior walls below grade. Does well as a passive between 63-52 F but Iād like a bit more humidity and temperature control from the daily fluctuations.

I wish! Canadian dollar probably doesnt help. Includes the install and HVAC side.

ah, that makes sense then - and not bad with installation, I had it professionally installed, which of course was extra - not something I would have attempted myself!

Was the split system worth it vs a through the wall?
Given my particular configuration, I really had no choice. My last cellar was through-the-wall though (in a converted walk-in closet off the master bedroom), and I was quite happy with it (also Whisperkool). We could hear it in bed, but just barely, and it became white noise.

Looking at creating a different / new cellar. Thereās a closet under stairs. Starts off walk in height, then slopes down, should be big enough to store a reasonable amount. One of the walls is adjacent to basement storage/machine room, so I could easily put some kind of cooling there and vent through the wall. Iām looking at some of the brands mentioned in this thread. I guess I have two main questions. One is for various of these, do they have a warm exhaust side, and should that be fine to just dump into the machine room without needing to reach outdoors? This is in a finished basement in MA. Second, I donāt really want to rip it all apart and put vapor barriers in floor/walls, so given that constraint does this skew my choice one way or another? Thanks in advance for any thoughts.
Thatās how it works with the self-contained units. You are moving heat from one place inside the house to another. How much space there is in the exhaust side and the insulation there determines how much youāll raise the temps there.
Youāll definitely need to make the cooled space much more air-tight and install a vapor barrier and insulation. Without it, given the difference in temperature from cold to hot, you will get condensation that will cause damage.
