The American Standard (Chinese Standard) air conditioner condenser at the old house. It is the model 4A7A6042J1000AB. It was installed in 2018 and has developed issues as of this year. There are a lot of 'Trane-washed' people that think these units are vastly superior to everything else on the market, but in reality they're just an overpriced piece of junk riding on a past reputation.
