There is no such thing that inverter air con only start to save electricity if switch on more than 6 hours. It's the biggest misconception I have ever heard.
Inverter air con start to save electricity once the set temperature is reached. In my case, it's only one hour.
By just switching on my air con for 5~6 hours per day average, my average electricity bill per month is RM30 lesser compared to previous. I know coz I have tried both.
just like my parent
water heater when on, need hit the heater few time only got heat come out
ask technician come to change new one, he say still can use, no need change, waste money, just fix it.
few month later, same problem, ask him come, he say than no choice have to install new one. that how they earn money.
same air con, come to service, say still ok no need change, less than a year problem come.
than this time i go buy myself, installer come check old one, compresser kaput, indoor pcb kaput
want repair compresser 300++, pcb 400++, he say you smart go buy new one, more worth than repair one old.
