Choice of 2 1-zone mini split and 1 2-zone mini split
Hi, I bought a 35 years old house last month. since it does not have ducts built-in, AC firms recommanded to use mini splits. I can have 2 1-zone systems, or 1 2-zone system. I know a little bit of the 1-zone mini split AC, but don't know how 2-zone works. I was told the two indoor units share the same outside condenser. just don't understand how the single compressor handle both evaporators, they may be on/off at different time, how do you check pressures ?(or it has 2 compressors in the condenser ? ) . 2-zone option is a liltle cheaper, but not much. Just wonder which one I should choose. What's the pros and cons ? Thanks.
