I am using a 2.5hp inverter Hisense and I really don't know why there are complaints about noise. It is quieter than my other air conditioner - 1 unit national and 1 unit York (probably because of age? Hisense is new while the other 2 are very old)

I was set on buying Daikin or York 2hp but for the same price I could get Hisense 2.5hp inverter. I figure it was a calculated gamble since it came w longer warranty and I get to save abit more on electricity bill due to the higher btu and inverter.

Somehow my unti came w/o instructions hence till today I only on/off, set temperature and adjust the fan speed. There are a few modes on the unti which I don't know how to use, just put under smart mode.
