Is yours a cassette unit? I have seen some pieces of polystyrene in cassette units before but don't be recall seeing them inside smaller indoor units.

Have to be careful. Polystyrene is flammable. I have seen an Acson cassette unit go up in flames and burnt kaw2. Fire was only put out by 2 fire extinguishers.

If it's taped on or movable then it should be removed.
This is to prevent crush crush crush damage to the fins as the AC IDU packaging is just a slip on cover, with foam end caps. The middle of the package is very susceptible to crush damage to the fins. Hence if got good deal from retail outlet I prefer to bring the AC home myself. Almost all the AC bought online needed fixing of the fins especially the ODU, using fin comb.
The main suspects for excessive gap will be the last part of drain pipe and/or copper pipes jutting out too much from the wall causing the AC to be pushed out at an angle. Usually the gap is only a small amount like typically 6-10 mm gap at most. The AC is hung up using the metal plate right at the top sections, so it could also mean the trench for those pipes weren't deep enough. You can try to troubleshoot which is causing the issue by shining a light in to the gap and record with phone camera using the other hand.

Since small bedroom may be overcooled (hence the AC on off on off cycle happen often) better get inverter for frequent use.
If only on like 10 times a year, no need inverter as hardly in use.

To answer your question, if you use it at reasonable temperature, 25-27C, yes inverter at partial load (low rpm) is saving power rather than 0_1_0_1 pattern of NON inverter.
And less stuffy feeling since its actively running slowly to maintain the target temperature say 25C and since the aircon is actively running, excess humidity is always being drawn out.

Without the inverter (gearbox) the only way to control the temperature, for NON inverter is on/off compressor only.

Was hoping to get some feedback in relation to AC size. This is my unit (around 1,700 sq/ft in size):



I'm pretty sure that all bedrooms and walk-in will use 1 HP AC each. Would love advice from the guru's here in relation to the AC for the living and dining area:

1. Preferably, I'd like to only have 2 AC units (although I'm open to suggestions)
2. The AC at the dining area, preferably should be able to also cover the open kitchen

Can both the living and dining areas use 2 units of 1.5 HP AC's each? Or better 1 HP in living and 2 HP in dining?

Thanks in advance for any feedback.

hi. why my compressor fan is on and off when i switch on my aircon? the aircon also not cold. please help 

but the compressor on and off in a short time like less than a minute. it is like more frequent than usual. i am planning to have a look myself first before call technician 

Hi guys, before PKP start, i bought Panasonic 1HP aircon (cs-u10vkh), but couldn't get it delivered until this week.
Suddenly the seller said manufacturer  are pushing for another model (cs-xpu10wkh) and would like to change our order to this model.
Is the new model better than the one i ordered?
Should I agree to the change of model?

I bought Panasonic CS-U10VKH-1 1Hp aircond in December, every time I switch on and sleep until the morning my room is full of dust, anyone knows why?

Thanks for the reply!

Do you have recommendation for Panasonic? Say if I relax the requirements a bit and can go without inverter? I have researched the Daikin's, but apparently for Malaysian shore(Oversea Daikin has different WIFI module), it has a closed API for the WIFI control as it is being locked behind the premium Cloud subscription (Paid premium to buy the aircond still need to pay for subscription ). I have experience with Pana and can confirm I can tape into the WIFI API without restriction.

Thanks once again!

Yes if I am given a choice I will definitely go for Inverter. The situation I have right now is I have a very niche requirement of WIFI enabled airconds for the smart home system. Hence willing to compromise on other aspects. Thanks anyway.

I am looking for cassette model though.

I am using Panasonic ac now.  Have been repairing the same problem for more than 8 times and still fail to get it fixed.
Mitsubishi ac is more expensive and some models come with easy cleaning feature.

I heard Mitsubishi ac is quieter than most of the other brands.

So since I last posted, there's one night where the AC stopped and flashed its error lights 2 times in a row, then it began short cycling again. It probably could've been repaired, but my mom said might as well go buy a new one. So we did that and we bought the MSY-JS10VF installed yesterday.





This is the first time we have an inverter in the house. Cooling wise, so far it's working really well. It's nice to have consistent cooling output during the night, and during a hot afternoon, it doesn't take too long to cool down to my set temperature of 24.

But I noticed the outdoor unit can get noticeably audible.
Just now I had it on and it was a hot afternoon. On max cooling capacity, the compressor seems to be buzzing away loudly, and inside the room, you get a bit of a higher pitched rumble. Which is kinda irritating.
And then once the room got to the set temperature, the outdoor unit slows down as expected on a inverter, and I don't hear noise inside the room anymore, but when I'm near the outdoor unit, the compressor noise is still somewhat noticeable.
Though when I had it on last night, I barely hear the outdoor unit at all. But it wasn't exactly that warm since it rained yesterday, so the AC didn't really need to work all that much.

Is this situation a cause for concern?

I expect compressor noise during operation, but it sounds louder than what I'm typically used to. Somewhat a higher pitched hum compared to my previous non inverter unit.

I'll run it again later tonight to see how it does. Maybe it's running at a higher capacity due to the hot weather earlier this afternoon.

Do you guys have this problem?

Panasonic inverter xpu series..
After turn off sometimes the flap dint close completely..
Then I need off the 20A switch and open back it will reset back the position to complete close flap..
