really? my aircons seems not cold enough.
the compressor also slightly noisy.
a bit disappointed now.

Out of few brands I see before, so far only Panasonic no need to add gas also cold enough. Other brands I not that sure.
My installer(my neighbor anyway) even dare to say if the air cond not cold, can knock his door and he will add back the gas and 1 round of weekend dim sum meal
But at the end, I never get free meal

Recent batch yes & old batch not need.

my mhi also no need liao

pros of mhi:

1.very cold like inside fridge liao
2. smallest indoor9 but thick build quality
3.
sleep mode, eco,hi power, timer
4.outdoor noise cannot be heard in my bedroom

cons:
1.quite noisy wind for indoor
2. the coldness can make your bone feel sick

What are the prices, and are they inverter?

Can set to quiet mode right

non inverter. for price just check on lazada. less than rm1k

can. use minimal fan. now using max fan cool mode

Should be set to minimum fan speed.

Unless you are fatty can't feel that cold.

installer recommend using max speed of fan to let compressor work easily compared with minimum speed

Use max fan speed the air output feel more windy than set to step 1st of fan speed to 2nd speed.

Just stand and use your hand and test the air result.

Again use high fan speed from the filter and coil can be easily suck up more n more dust too.

Wanna do service faster then just do with high fan.

When my Mr Slim was installed(Brand new btw), the installer didn't fill up the gas since it's already charged in the factory.
And it's really cold when I use it.

There's depend on back to back or either pull from 3m length distance will be poor cooling

Well before I got this Mr Slim unit, I got a Panasonic unit and the outdoor unit is mounted on the same wall as where the indoor unit was(Bad idea....Alot of vibrations especially a few months before I got it replaced)
When I got the Mr Slim,The outdoor unit was moved a few meters away and it still works fine.

Oh and this is how the unit looks like

Wow left side too close to wall, maybe next time is a bit difficult for wipe out

The previous aircons were also installed like that for years since I was in the house.That was in the master bedroom.I got no problems with that install and it's still easy to remove the unit for servicing.
Originally I got an Acson in there.Replaced it in 2006 or 2007 with a Panasonic(When it got replaced the Acson was moved to another bedroom in the house since it was still working fine.That Acson unit was then replaced a few months later with a Panasonic unit which has e ion something and Patrol Sensor)

The Panasonic in the master bedroom runs good until 2014 when it started to make alot of noise and doesn't want to cool efficiently. When it comes to December, the condenser fins on the outdoor unit is rotting away, making more noise and the indoor unit doesn't want to cool(Even at 16c).The outdoor unit compressor would run for a minute or two then stops running for a really long time. Tried servicing it and still not solving problems. Then just screw it and replaced it with the Mr Slim in January 2015

That's how the Panasonic in the master bedroom looks like before it was replaced with the Mr Slim

He he maybe was personal style.

Btw non inverter need standard presure only, unlike inverter need 100% of gas R410a, from inverter Aircon just slighly lower pressure can be feel slighly different, even setting can be 24c vs 25c if the gas is up to 100% of pressure R410a requirement
