Anyway non inverter 1.5hp will be slighly bigger than 1hp.
Different brand also got different size.

1hp can't used 2hp or 2hp used existing 1hp copper.

More fixable from inverter units size.

Inverter unit should be at the being starter was loud sound after indoor has been feel cold may reduce outdoor speed & fan noise.

trying to turn on early before you sleep.
And don't set too low temperatures like 22C or high fan speed such as 3 bars, otherwise no help much, the fan speed in high mode will tell outdoor works as high noise too.
Like set too low temp also tell outdoor compressor works in louder

You need to call back Aircon man come to check and pump in gas and check those outdoor copper flare nuts else.

Not too sure, you can call to MHI serving and complain not longer cold again.

But act like dunno anything and see how to do for you.

Then you should clean it before call them, once you lazy should related for others matter too

Just open up the front cover and take out filter see wether is dusty or not.

He should never drink ice Coke in the class

Condensation not related to gas, just the copper pipe expose air and the pipe in cold condition may cause on condensation, if no condensation that meant indoor not cold enough.

You choose cold or warm?

Not sue how higher from the outlet pipe to the floor, try to extended the PVC pipe into floor and made it fall smoothly, to prevent mold on the wall else.

Actually from 1.5hp and above better dun used, the copper can't take the higher pressure at all.
Even old wire can't used as well.

Also old insulation can't take the condensation as well.

Better do it in 1 short

York still under markets?
Seem like nowadays all under Jonson control OEM by China made.

Better get Daikin still under York DNA, unless you get R32 gas from Thailand or Japan only

Should try their inverter models, my sister-in-law house all Daikin GA and my wife kampung still under York。

But inverter model so far so good already 3-4 yrs now never claim any cents.

In the real world, usually much expensive stuff would be the greater.

Non inverter 1hp vs 1.5hp inverter you pay the amount of bill from 1.5hp inverter must energy saving than fixed speed type of 1hp non-inverter.

Now still got York meh?

Previous model is it?

This one OEM from China made products such as Electrolux Aircon wow.

Why not go with Daikin?

Get basic Daikin inverter 2hp you won't regret one
