Panasonic X-Premium Inverter & X-Deluxe Inverter has them built in now. Standard Inverter need to buy external CZ-TACG1 adaptor to use with wifi.

but the smart control of Daikin is to download their app and control with app only, that's convenient

Hey all, wanna ask you all ah, usually how much is the price for installing a new air conditioner in KV area? Cause the air conditioner repair guy came and checked my air cond and recommended me to change new air cond. the model he recommended he quoted me RM1.4K, I did a quick search on Lazada, that Panasonic model is only about RM1K, even SenHeng is selling at Rm1.2K. That’s why I’m thinking to get someone else to just install instead if that’s the case.

If you want to save cost, then u can install the aircond all by yourself. It's very easy only. Plenty of youtube videos on teaching how to install.

I think pretty much the same with Panasonic's Comfort Cloud app. can also control the newer models with built in wifi. Daikin if not mistaken does not have it all built in some models too.

Did he quote you RM1.4k with installation or without?

What is the problem with the current AC ?

Normally for new installation, is about 150 to 180. Some installers will also charge to dismantle the old unit.

The board spoiled already. And it’s already 10 years old. Very hard to find parts.

Now that I think about it, maybe his quoted price is not so bad I guess. I live in high rise condo as well.

You can go all the way to save hundreds of ringgit by buying them online then paying installers etc, but costly in time. That what made me went offline for this kind purchase, sometimes its not worth it to wait for a very long time just to save few hundreds.. if involving few Ks maybe.

No harm to shop around.. the usual rate should be around +230 to the price of aircon 1hp from electrical store (eg Jintex, Legend) to get their "panel installer" for standard installation. I am reading it as a not much work required beyond remove existing old AC and hooking up the new AC, since piping and power point all ready.

I have decided to go with his quotations. I look at the compressor for this particular unit and its really not easy to remove the old and install the new one. They will have to climb a lot and risk their lives too. Also will need to dispose the old units and etc. since they did come and check already so ok la. If i get another contractor they might tell me one price now, and then when they visit my unit, they might tell me need to add extra costs later.

Have a 2.5HP Daikin Q Series FTK25QV1L inverter type made in 2017. Used only once in a blue moon.

Recently, stopped working with a U4 error code on the remote control.

U4 is a communication error, meaning internal unit is not talking to external one.

Fault is probably the PCB of either or both units.

Does anyone know of an independent air-cond service guy preferably around Rawang who know his way around electronics? And charges a reasonable price, of course.

Called one guy over; he has been giving me the runaround about sourcing the circuit boards...so looking for other more competent source. If I go back to Daikin, they will likely charge me more, unless i'm wrong about this assumption.

Is the PCB in both units easy to replace ...like just unscrewed a few wires, and remove the card from a slot?

Do most installers know how to fix such a specialised problem besides cleaning air cond, flushing fluids, top up gas and piping works?

Bought the air-cond in 2017 for nearly RM3K....If the card (s) are going to cost me more than RM1K, I might consider getting a new air-cond.

Signal wire broken or faulty, can cause comms error. If u can access ODU safely, ie no skylift needed, the signal wire can be disconnected at both IDU n ODU.

Ideally should be 4 wire LNE+signal.
But a lot of cut corner installer just use LN+signal (no E).
In such case its typical they use the green wire supposed to be for earth as signal cable, and the earth is left unconnected.

Then using another long cable connect the signal terminal at both ends (IDU signal with ODU signal). If you don't have spare long cable you can buy a roll of cable like this and see if it resolves the comms error problem. Since data is low voltage u can use cheapo "control cable", can get it at 30 bucks (buy the 1.5mm in white so to differentiate function away from the power carrying cables, and so you don't use it for anything 230V); https://shopee.com.my/product/95690451/2092126240

Its a 30 bucks experiment to see if signal cable broken somewhere in the hidden wiring. Even if got multimeter to test continuity still need this long cable coz one end cannot reach the other laugh.gif

If the "bypass" works then you can narrow down the fault lies in the signal cable is broken somewhere. Then later u just need to find a way to hide it or route it with hot glue gun drops so its not too obvious lah.

Hi guys, I'd like to seek or some advise / opinion / experienced from here if any -- regarding multi-split AC.

to make it short, I would like to exchange my current x3 unit of rooms AC (of coz after deep assessment about my requirements) given by developer to multi-split unit, because 1 of the compressor is located in yard, and I'm gonna seal my yard with sliding windows, will be indoor most of the time.
So after I replace, there will be only 1 compressor for rooms sitting in my balcony (another 1 for living room, untouched)...

put aside about the cost needed, I've been engaging with a few AC guy/contractor, to ask for quotation about my plan for the replacement.

But almost all their respond when hearing i wanna use a multi-split AC is like a big NO..... wave.gif
Among the reasons are...
1) if compressor went down, all rooms no AC
2) if compressor spoilt, hard to find spare part
3) it's very expensive, not worth the cost to replace and exchange.

so I'm wondering is it really that bad for multi-split AC? hmm.gif
this multi-split AC so fragile one meh? so easy to spoilt?

even i went to some AC supplier shop when I'm asking for multi-split AC price, they look at me like alien... doh.gif

i know it is not so common in Malaysia for this type of AC, but I'm not sure are they really not recommended, or the contractors themselves also not familiar with this and refuse to bring trouble to themselves?

I'm really confused.. confused.gif
hope any taiko have some valuable input that can share with me?

I see alot of air cond installers they just install the unit without doing vacuuming.
Will that have issues in the long run?

1. Is quite real. All eggs in one basket prob.
2. Got money all can find one.
3. Marginally more exp for smaller units but if u have at least 2x 2hp in the multisplit it can be cheaper than individuals.

Typical contractor in MY lazy to read up on how to do. Overseas in SG, AU, and HK multisplit is common item. In SG it seems to be common HDB rule to have only 1 ODU so multisplit (aka System 3/4/5) is the way. It is just a bit more complicated in bussing out the pipes and power only. Not rocket science..if u did LAN cables from a switch to several PCs u get the concept. In MY it is less common because most homes have enough space to stuff 2 to 6 individual ODU easily.

Ur best bet is finding those online seller that sell multisplit and get them to recommend their panel installer.

Vacuum pump not cheap. By right that is the way.
Price RM10 more than other installer, customer straight go to other one.
MY consumer behaviour..lowest bidder that can make it turn on wins. Whether AC lasts or not..to the cut corner installer = NOT my house NOT my problem tongue.gif

Can.. if you can access the air conditioner, you will see the nanoe-g needle with a blue/purplish light on the needle. According to user manual, the needle and metal plate around the needle with a dry cotton bud once every 2 weeks.

I have asked a few installers, if there is air trapped inside the system, residue (compressor oil, moisture and/or debris), cooling performance will drop, and it will affect the compressor in the long run.

Bought Panasonic CS-XU10XKH (1hp) for RM2125(5yrs warranty) from Senheng.

This AC will be installed at my new house. Do I need to do vacuuming too?

Thanks.
