Gets real complicated though - where are the parts that are assembled into a car in Ohio made? Are they shipping circuit boards and fuel injectors and tires to Ohio from Japan? China? Germany?
Fact is, your not going to get anything made that is wholly sorced from one country, much less excluding parts made in China. From the rolled steel, to the aluminum, to the copper tubing, to the smt parts on the CCA’s in the controllers, some part of it is going to come from China.
The reliability of any ystem comes down to the quality control and the design. If the guys desigining it are From Japan, and the manufacturing standards are Japan, even if it’s made in China, the product will be a solid build.
But the OP doesn’t want to give any money to China. Well, tough. I’m in the same boat, but if it means I give $70 to China, so the Japanese manufacturer can get $300 wholesale, and the US installer/retailer gets $300, and I get a highly recommended piece of equipment that will run trouble-free, so be it.
OP want’s all or nothing. our not going to get something with no contribution to Cgina. If you want it that way, move north, then and you won’t need A/C.
