I'm using Mitsubishi JS inverter 2hp at living room, daily 6 hours as I'm WFH especially hot weather. This was oversized after recently we installed a plastic curtain to block air free flowing to kitchen, so setting 30c silent mode fan speed is already over killed, managed to drop room temp from 32c to 27c which was cool enough for small living room, ampere hovering 2A at night to 4A during afternoon.


Bill with 3 AC, 2 bedroom on 15 years old mitsubishi heavy industry 1hp, but we usually uses less than 30 mins to cool the bedroom then off and use stand fan.

The disadvantage of oversized AC I guess is hard to control the temp, set 30c it drops room temp to 27c, set 29c it drops to 26c, making hard to set properly the room temp. Or is this Mitsubishi thermostat not accurate?

You know this May and June was heat wave period right? Many nights too hot have to wake up switch on aircond on bedroom for 1 or 2 hours...
January was cool period so bedroom didn't switch on aircond for many days.

No consider other option?
