Sorry mate, not picking on you, but I always see this kinda question, on all product topics, not aircon only per se.

To me, there is no such thing as the best, else that One product would have been in market dominance!

It comes to customer requirement and needs, all general brands have good products, but some models performs better than their own other model, so its not brand specific but model, and this is where we start to compare spec, warranty, etc

Recently I've bought 2 penasonic 1.5 & 2.0 XU series AC from lazada by using save 2.0 voucher and 3 units Panasonic bayu 5 fan.
But I found that, a lot of shop are out of stock for Panasonic products, not sure what happened to Panasonic. What's wrong with Panasonic now?
I prefer to have same brands for whole house.
So still need to buy 4 fan, 2 wall AC, and 1 cassette. But suddenly feel x confident with Panasonic. lol
I asked few shop nearby my house, all Panasonic AC out of stock too.
So I scare the Panasonic spare part might difficult to find in the future, was thinking to continue buy Panasonic AC at lazada or change to other brands.
Any suggestions? Or any recommended brand & model for AC(1hp & 1.5hp wall and 2.5hp cassette?

for aircond, spare parts is the least of concern.

parts that usually spoil have lots of generic parts. ori or generic for those parts dont matter much.

for parts that matter......usually it is not worth the repair.

No one size fits all just like cars.
Things that are best for racing may not be the best for office lady who just wants a cute fuel saving ride.
Or a large MPV may be best for large families but is hard to park for someone who rarely fits more than 2pax in a car.

In AC perspective generally the same. Certain series from a mfg may be best in class. Other series may be lousy spec and just buying for the brand name only.

Generally still need to do deep dive, as a start compare BTU, ST star rating, for upper range models they will have nice to haves like room scene camera, x axis vane auto control, coloured panels, wifi connectivity either built in or as addon module.

Colour aircon may stand out too much vis-a-vis typical white ceilings.. even if you make neon pink or lime coloured aircon some people will still buy..but probably not the mass majority.

Just like clothes..when in teenager age still can pull off all those loud neon colours..but generally these will not be so appropriate in an office setting, too catchy.

Whilst you can still get brown tan and blue-silver in the more premium hitachi SX n VX series

Generally chair sized portable aircon never seem to work well as the airflow through the heat exchanger (ODU) is what cools down the room quickly. Unless it is those event type like a skinny and tall fridge size.

Between a portable AC and a window type AC the window one will still run circles around the portable "air cooler"; ducting the hot air away is still a headache.

Yes this is true..many factors/variables to consider, cannot have everything at once and cheap some series built for pricepoint. Some series better built, but not so cheap. Some series suck spec wise that it basically lose out to almost every other brand, that we call it buying for badge only.

Im looking at models such as this
https://shopee.com.my/ELBA-PORTABLE-AIR-CON...43565.305058738

Thus far, found there are outlet type for water drainage and some has it as tray type where, one has to discard the water manually.

Any other things that need to be considered, since its a outdoor unit for family gatherings.

Thanks

Will work for indoor closed space but seems underpowered for outdoor usage. The air will get dissipated all over. Outdoor cooling best using screw chiller

For cheaper price, industrial stand fan may be better VFM (value for money).

panasonic inverter air cond laku keras due to save voucher. ask some seller give same feedback.

I wonder about this also. All the shops giving the same answer, have to wait around one month only can get. (May)

Thanks for your replies. I don't mean to offend anyone with my initial post. It's just that honestly, my family and I have not bought an AC for nearly 10 years and as a result, I'm really in the dark as to what's good and what's not. The only thing I know is the HP that I need in my new place.

Was hoping to get some feedback/recommendation from members as to what they think is the 'ideal' AC and based on that, I'll do some research and if it ticks all the right boxes, it'll be on my shortlist. I don't want to go to the shops and be steered by salespeople who may have a hidden agenda (i.e. Samsung gives better commission so they'll promote accordingly, etc.) and value honest user feedback above all else.

If I had to, the criteria's for my ideal AC would be:

- Reliable
- Energy efficient
- Quiet
- Invisible (if this isn't available on the market, then the lowest profile possible because I hate an AC that I can see)

I know it's not much help, and I appreciate any suggestions. In the mean time, I'll continue to lurk and hope to learn from the discussions here.

No problem, we all learn from each other....i would suggest, to check on ceo's posting, she has posted many valuable guides!

Just click on the right handside of her posting " Show posts by this member only" and you could find her postings, its really helpful for beginners.

here are one from her posting above, personally I start with BTU and then rating, ERR, etc

Any recommendation for 2.5hp inverter cassette?
I'm thinking which one should I buy, I want to get Panasonic S-24 but 410A refrigerant look outdated. Panasonic don't have R32 inverter cassette therefore make me feel hard to do the decision.
If u were me, which one would you buy?

Panasonic (410A)
S-21 btu 20500 RM 4299
S-24 btu 24200 RM 4519

Daikin(R32)
FCF60C btu 20500 RM4759

For a more indepth analysis between R32 and R410 can refer here
https://www.sciencedirect.com/science/artic...140700712003532



R32 does have its eco friendly benefit in terms of ozone depletion, but for very hot ambient (46C) it start to struggle. Minus 18C not achievable unless you're doing cold chain logistics. Between these two extremes at normal malaysian ambient ~30-35C no significant diff between R32 or R410 cooling performance.

In terms of model wise as long as it has an inverter, even R410 also will work well, coz it can run in slow mode when it has reached target temp and continue to dehumidify the room - whilst non inverter will stop the compressor and run fan only mode in the IDU - it starts to get stuffy*. Do note, Inverter will begin to save power only after the room has reached target temp ya.

*and this is why some ppl who were used to the non inverter models always put it freezing cold at 16C to force the non inverter AC to run nonstop
*this behaviour of setting extreme freezer temp at 16C to force AC to continue running all the time is not required as inverter ACs still continue to run slowly even after it has achieved target temp of say 25C, as it didn't fully stop, it will continue to dehumidify the room

The 24K btu Pana looks like a better bet in terms of btu to $; as it will be able to cool down the room faster than the other 20K btu models shortlisted.

In terms of big AC longetivity..R410 compressors may actually last a bit longer than R32 compressors as the R32 ones run hotter than the R410s.

Lol, I should start online crowdfunding then for the screw chiller!

Nah, its too hot at the patio hence having a fan is not going to be please. Since there are 3 walls and one opening at the patio, I think AC is fine, but obviously as you said the cooling wont be there, which is fine, as long as cold air blowing at the guest, is fine.

Need to do further research and walk in store to find out on their variations.

cheers

For this specific use case.. can also consider installing a few units of the KDK wall fan (KC4GR). Stagnation of air also contributes to hot air.. if the air can move fast enough then it will not have time to heat up

I have this at home, why it cost a premium over the other wall fan is in the blade tech. It really focus a "beam" of air as if there's an invisible pipe from the fan.
My yoga studio that installed a dozen of them (the room is pretty big and can fit 30 pax at once all spaced out per SOP), it doesn't feel hot even w/o AC.
The only bad part is caused by its efficiency to move a lot of air (in continuous 16hrs per day duty) you will need to clean them often coz dust buildup fast.

Air chiller will need to be of a bigger unit that roadshows/events use, otherwise its too tiny to make a noticeable cooling effect.

Great, so I buy Pana 410A 24k btu won't regret right? Haha

No regret best price/perfomance there.
R410a is actually a mix of half R32/R125 anyway

Here is the panasonic inverter 1hp current usage from my HA. Can see the step up and down when room temp archieve .

Since we are on the cassette topic, what about the Mitsubishi r410 inverters? Even cheaper than the Panasonic.

How do you spot a good air-conditioner servicing and an average one? any difference on the detergent (red colour cleanser) they use?



By the way, service interval for a 2HP air-cond should be like? once a year?
Washed the filter once a month.

Hi there all, any alternatives to Hitachi and Sharp Inverter Models?

I was recommended 1hp inverter aircond with BTU >9700, with these 2 models Sharp AHX9VED2 and Hitachi RAS-X10CJ, however no stock.

Any other model numbers to recommend? My room is Bedroom 2 14 ft x 7 ft. Ceiling height 2-3m?
