What is the model of Panasonic cassette that you have bought? The height should be on the body only. Panel will exposed, so that height shall not be calculated.

I am looking at the Panasonic FS series catalogue. 2HP inverter and non inverter cassette body height is 246mm. Panel is 45mm. Panel shall not be calculated in the depth. He might need to run drain pipes.

Yeah...go check it out. But no point going to those electrical shops like SenQ, HLK, Harvey Norman. They don’t carry cassettes. Look out for those official dealers. Even though the Panasonic Cassette has drain pump, the pipe does not need to be elevated. You just need to make a U trap for the drain pipe and you are good to go…top clearance is not necessary for cassette

M is non inverter. Y is inverter.

I will be using M series for my Living. Just scout around. Good luck

Woot? BTU does not affect the sound, airflow and installation do. If you are worried, check all the airflow and noise level from the catalogue. Well balanced units will cause very minimal rattling hence low noise. New units will have no problem given that you install it properly. Unless you are talking about the airflow’s noise la, which I think it is negligible. And how is net weight in this kind of room air conditioners affecting vibration? It is not like the units will be shaking. Panasonic 1 HP indoor weight is 9kg, outdoor is 21kg. How loud can it be? If you want minimal vibration on your outdoor, put on a rubber pad under the outdoor unit. Indoor units wise, no cure. Just get a pro installer and service man to service your AC, to make sure that they put back the parts properly once they have done chemical wash

Onking personally is a rip off. I will not go there for anything. However, I believe what irwan got is a good deal. S-10 cost 1400 if it is as other place. Heck, C-10 cost u 1100 at dealer's price. So if you plan to buy pana, grab them la.

You sized your AC wrongly? I believe so. I also strongly believe that you did not factor in the sunset factor into your calculation.

All Pana non-inverter AC using R22. Inverter using R410a.

Inverter - S and PS Series
Non-Inverter - C and PC series

R22 is going to phase out soon. 2020 if I am not mistaken. New manufactured unit after 2020 will not use R22. Right now, if I am not mistaken, there is no more new/ virgin R22 manufactured from 2012. All that they have in the market is Reclaimed R22.

L series York is just like M series. M series is with ioniser. L series is without. Spec between the 2 is the same. J series is with another kind of ioniser. Do not know the ioniser difference between J and M. Do not know which one is the newer model. J first, K, L, M?

M's spec looks better with lower power input hence better EER. I just got myself a M.

There is no more other info that I can provide. Try also to venture around for brands.

The last time I looked, M is better than J. No? Spec includes power input, capacity, Amp

The one with ion is with another layer of silver/ white/ grey glass like material on panel? That is M series. The one with the slit on the panel is J or L.

I believe she is talking about J and M series? I am not sure.

It is the same for unit with 24000 btu/h. But for others, it is not the same. M series has more capacity variation across its range. Not sure how L is different from J.

I do not know the interior parts.

What is AC jelly?

Please let us know properly where this is formed, how does it look like. I have never seen any jelly in an AC.

Higher capacity unit does cool the room faster. However, if your room only need 1HP but you put a 1.5HP, you not only waste initial capital, have higher electricity bill, and also resulting in alot of cut in cut out of compressor.

Even with inverter, the min frequency that it can run maybe 20Hz for certain brand, can only run for a specific amount of time. If the room temp does not rise, the unit will be forced to cut out. In that case, if start stop is so frequent even with inverter, what is the use of having inveter?

So size your AC properly. Don't just go for the biggest available.

Also, EER is just a reference. How they got their capacity depends on how each manufacturer do their testing. There is no apple to apple comparison for AC in Malaysia. Even if with the star rating, it is a relative comparison. The most accurate comparison is NEA from Singapore, where one stop testing for all brands under the same condition. Therefore, it will be apple to apple comparison. However Singapore unit spec can be different from what you get in Malaysia for certain brands to pass regulations and what not. But I guess, it will be logically dumb to choose a low EER unit from a high one right?

I think the price is dirt cheap for inverter.

Still it is dirt cheap. You sure it is 2080 not 2980?
