Midea made the Ameristar outdoor units, coils & air handlers for Trane for a number of years. Our local AS supplier said the A/Cs worked out well, heat pumps had defrosting issues so they didn't really push them.

I've seen ICP units that flat out have the ICP brand sticker on a mini split outdoor unit as well as Midea's. From what I hear, Carrier has some money in Midea. And they make the inverter heat pumps that are lower buck than the rest though I think the big names are learning the rotary compressor, standard controls method too.
