Just installed a Carrier (40MAQB12B1 / 38MAQB12R1) mini-split in the shed, which I had spray-foam insulated (and then I installed drywall) beforehand. This for the work-at-home thing which we're doing for at least another 6 months... The difference between the loud portable unit and the blessed silence and efficiency of the mini-split is chalk and cheese. There really is no comparison. The mini-split cools the shed down to 72, where I have to increase the temperature to stay comfortable, in about 4 minutes. It's even silent outside, and these units will provide 12k BTU of heating or cooling, so it'll be useful in winter too.

Yep. Had a Fujitsu halcyon 18,000btu and you could not tell it was on. Prior to that I had a delonghi "penguino" 13,000btu portable AC (it cascades water over the hot side of the condenser and ejects it out of the exhaust line) which is light-years ahead of these models in terms of efficiency and quality and it struggled to cool 500sqft while the mini split can easily sustain temperatures in 1200sqft. This particular model can also heat with exterior temperatures as low as -26C (~ -15f) which cuts a ton of heating costs - heat pumps provide ~3x more heat per watt than baseboard heaters. Add to this the fact it's nearly inaudible inside or out and I can't imagine why someone would choose portable ACs over this - even high end ones. The installation is quite straightforward despite requiring a technician to do the refrigerant part and confirm the electrical setup.
