I have not been able to find an answer to this question. I am in Mexico and all the homes are 8 inch thick concret walls so mini splits are the AC of choice for retro-fitting older houses here.
I understand the negatives about over-sizing....so, If I have 3 rooms requiring 8,000 btu of cooling and have a single 24,ooo btu compressor to run 3 mini splits what happens when I run just one mini split? Am I now way over-sized? Or are the new units smart enough and capable to run the compressor as an 8,000 unit (I forget the technical term, but understand comercial units are able to do this)?
Thanks in advance,
