Minisplit vs. adding through wall A/C in six unit brownstone

[Jessica Seigel]

Should I bash two halls in the rear of our six-unit brownstone for through wall A/C or install a mini split system? The price difference of course is huge and these are SMALL apartment studios. We have steam heat and the mini split would be largely for A/C. The problem is individual electric metering.Is it possible to run lines off one compressor  to units in two different apartments and somehow meter them for their individual electric use? Your help much appreciated. Jessica
