about 8 yrs ago, installed 8 units at home 1. Hitachi still runs well, no any service call. Teco, called a few times. Sampo, 2 units were dead in 5 yrs. replaced by Sharp and Tatung.
home 2, around 12 yrs ago. Kolin, dead for yrs. Toshiba, runs well. Sampo, runs well. Panny, sometimes ok sometimes bad.
home 3, 1-25 yrs. Hitachi x 2, run well. Panny, runs well. Sharp, runs well. Sampo, runs well.
seems JP brands still have bit better reliability, especially Hitachi!
next time, most likely is to take Hitachi for all.
FYR, I Daikin TW boss, but I don't buy his AC........ only bought his air purifiers.
