Hi sifus, newbie here.

I have recently bought a Sharp aircon from Lazada to replace my 10+ years old AC, want to confirm with you guys if the aircon will fit my existing piping or not.

My old AC (IDU and ODU doesn't match)
IDU: Toshiba RAS-13YKX
ODU: Upson UAC-N19C (cannot find anything related to this)
BTU: roughly 13000 after converting from kW
Suction line OD: Toshiba spec sheet says 12.7mm (1/2 inch), but I measure my old line is 9.52mm (3/8'). Attached spec sheet as pic below.
Gas: R22, old pipe so I expect thickness is 0.51mm at best.

The AC that I bought on Lazada
Model: Sharp AHA12WCD
BTU: 12390
Gas: R32
Suction line OD: 1/2' from website

My original piping is concealed so I really prefer to use back the old line. I am aware that R32 operates at a higher pressure and I am willing to take the risk.
But now the main question is if my original line will fit my new AC set or not? Any advice?

Update on my bad experience with Daikin.

I bought 2 units of Daikin R32 Inverter 1HP FTKC at same time around year 2017 for different rooms.

On June 2020, 1 of this unit show error U2 and later L5 and the outdoor Inverter PCB was replaced.

Fast forward to current Aug 2020, another unit encounter the same problem, U2. This outdoor unit is fully hidden away from sun and rain.

Currently planning the take out the board for repair at Ingress, a PCB repair company instead of paying 600 plus for board and labor.

*-:': Daikin and ✓×π^{ Inverter.

L5 error code is very irritating, the unit will shut down itself.
My unit installed in Penang , Dec 2019.
By early 2021, unit start to have L5 error.
(Did not use the unit for a few months because  of MCO lockdown in KL )
In actual operation time, definitely less than 1 year.

I wonder how many other people are experiencing similar issue with DAIKIN inverter AC for L5 error.
Installers  would stay away from BRANDs which has frequent and common issue unit malfunction.

Surveying cassette aircond for my living hall, developer provided 9.52/15.88 piping for the hall... the showroom was using 3HP, but I'm considering 2.5HP or 2HP cause I kinda "partition" the area a little bit so place is a bit smaller. But when I was comparing the 2HP and 2.5HP... the 2HP seems like very close to the 2.5HP peak power? but is cheaper and even more efficient. Am I missing some important info perhaps?



But comparing the specs here... looks like the Daikin 2.5HP is pretty underpowered vs. Mitsubishi's 2.5HP right...

Add Pana to the comparison. Their cassette btu rating also not bad.
Yes the stepping in aircon models are not linear..meaning not all the steps in the staircase are same height.

That's why if u wanna dig into it, easier to classify by 9k 12k 18k 24k 30k btu classes rather than so called 1.0 1.3 2.0 2.5 3.0 hp

Not all series of D are great performers. Same as buying 316i for the bimmer badge only.

I have a cassette ac at home and it's freaking eat electricity like there is no tomorrow.
So i advise not to install one at residential...it's more for commercial.

Is Mitsubishi Electric aircon good? Which model should I buy?

This type of Q is 'dangerous' without details of the place. A salesman will sell the highest spec.

Why Mitsubishi and not Daikin, Hisense, Pana, Sharp, Hitachi etc ?

2.5HP Premium Inverter R32 Air Conditioner CS-U24VKH -1

2.5HP R32 X-Deluxe Air Conditioner CS-XPU24WKH-1 (CU-XPU24WKH-1)

Which is better ya? both also panasonic.. i tried to see all specs tapi macam not much difference. one model got some yang the other model dont have and vice versa.. any idea which one is better?

Other than cooling hp, other specs are only good in the manual or brochure.

ya both also i think similar in terms of cooling hp so i also unsure which to pick

I always buy basic model for ac. To me, cooling hp is paramount which is the purpose of AC.

For other features like air purifier, I prefer to buy a separate unit.

Btw, which A/C brand should we avoid at all costs?
