Inverter question for Eugene

I have noticed that most if not all mini splits use a rotary compressor. Why is that?

Why not use a scroll?


  • Good Question

    I get asked this a lot and the reason is simple. Scroll compressors are not available in small sizes (typically less than 2 tons). Single zone ductless split systems are often available with capacities as low as 9,000 btuh and there simply aren't scroll compressors that small.
