on the panasonic aircon just finish install 4 unit today by the aircon contractor, but funny story is that one compressor had writing on the top "sensor had issue" but still pack in the box, complain to TBM they willing to exchange another unit but the real story start here rather the unit being send back to the manufacture they simply clear up the writing on the top of the compressor and repack and sold again.

1st how come the compressor had issue pack and send to the customer
2nd are the retailer want to get more profit by selling issue compressor
