About pana reliability or other AC  reliability  really  hard to say.  without  the real figures .

I will favour  AC  with longer warranty  as this is a good indication of Reliability .

I also speak to various aircon service/installers and they recommend Panasonic and Daikin. Of late they seem to recommend Daikin more, something to do with Panasonic using smaller fan.

Of course I’m a small sample size, but I do have 3 Panasonic that is older than 10 years (The heavy usage 1 died).

All also quite noisy you can hear the whirring of the fan, I'm currently running a Honeywell hepa filter.. the wind noise cannot be eliminated, normal use ok.. use when sleeping kinda annoying

My Sharp on lowest setting (auto) is quite quiet. But of course it's not right next to me. About 6 to 7 feet away.

Dysons are noisy. Ok seems like we deviated from air conditioner.

Basic conclusion is no air conditioner will filter the air as good as a standalone air purifier with HEPA filtration

Thanks for the info. Any idea which looks better from these 2 Pana models? I can only see the Nanoe X as the main difference.

Premium Inverter R32 Air Conditioner

X-Deluxe R32 Aero Series Air Conditioner
https://www.panasonic.com/my/consumer/air-s...xpu18wkh-1.html

The basic inverter would be good enough. You want nanoe or some air purifier, just buy the standalone air purifier.

Go for daikin inverter lah.
Panasonic good looking , but not cooling enough
Midea cheap but easy to spoil and parts

I hate to admit this, but from experience it is true. Panasonic skew towards power savings so it is never as cold as Daikin, even when I set the setting to max on remote..its still hesitant to cool. Like, I set max fan, 17C the air con is like "you sure you want so cold meh? eh it use a lot electricity, come I slow down a bit save some energy". I am like.. eh hello, I want max cooling you give me max cooling la.

Limpeh using 2HP inverter Pana in bedroom. Based on measurement of room size & height actually 1.5HP enough. Now 2HP inverter Pana, just ngam ngam only.

Midea cheap and easy to spoil and parts? In 2015 I got MSN-09CRDN1 inverter models, 3 units used heavily because all in bedroom, until today no issues.. except workmanship not good the thing leak gas for 1 unit. Not the a/c's fault.

But best bang for the buck, HISENSE. If you want the most basic non-inverter aircon, limpeh will recommend Hisense over any Pana and any Daikin. The Japanese very expensive.

EDIT: Limpeh got Daikin, York (old cooling king good, current China mari Johnson control is rubbish), Hisense, Midea, Mitsu Electric, Pana -- love hate relationship with Pana.

4. Suggest to go for inverter so even if you go with much higher HP it does not affect so much as the power is variable from around the range (for example1A to 4A and not just 4A when compressor kicks in).
*
Expert in the house.

Many people don’t understand this feature of an inverter aircon and think only about the power saving aspect.

My room only needs 1.5hp. But I went and whack a 2hp inverter unit.

Best of both worlds, it gets the temperature down rapidly, then slows the compressor down to keep it there. Super comfortable. Recently ambient temperature is cooler so I run it in dry mode to reduce the humidity.

What do you consider necessary?

I’m just impatient to wait. I cannot take feeling hot.

Plus our ambient temperature is hotter than usual sometimes, I want to ensure I’ve got all the cooling power I need.

My brother did the same, 2.5kwh daily which isn't bad. I'm quite surprised by the power consumption.

I didn't oversized but I bought 2 LG dual inverter ac last week. What I'm planning is reduced the power consumption manually instead which is an option available on LG. My wife wants ac but I didn't like the winter feel. Thus instead of relying on the inverter to kick in, once the room cool enough, will manually reduced power consumption to either 60% or 40% so that it felt comfortable.
*
Yup, my inverter unit won’t give me winter feel even if it’s overpowered. The ability to slow the compressor down is really great to give me the exact temperature and humidity I want and hold it there. Coupled with my temp & humidity meter it is always consistent.

My living room with open space to dining and kitchen and staircase, I’ve got 2.5hp and dining with 2hp. Crazy overpower but those units are not inverters. I almost never use the 2.5hp, just the 2hp. Cool enough. But it was overpowered because if there’s family/social gathering with lots of activities, 2hp alone won’t be enough.

What’s the point of having AC if still hot?

Looking for a aircon for my small room.. 8-10 hours per day, my temp setting normally between 19-22. Is it better to get an inverter or non inverter? Based on daikin heat calculator, I need around 9500 btu/hr. Looking for one that is easy to repair (spare parts, just in case), quiet and energy saving... Budget under 1.8k. Thanks
*
Your usage pattern, inverter. Easy to repair take Panasonic. If temp setting 19-22c, you should get 1.5hp.

Oversized hp for inverter air con is not a concern if you know how inverter works. I run a 2hp inverter in my room.

Yeah, that wall is indeed facing west, got a bit covered depending on time of the year (another tall building nearby). Moved to new place, minimum bedroom is 1.5HP... which can be a bit slow for my smaller bedrooms too. Master bedroom is 3HP (cause 2.5HP no stock, +RM100 to move up), very shiok... within minutes cool down already.
*
Inverter right. 3HP is crazy overkill. If it’s not inverter in a room it’s going to cut in and out constantly. My 2.5HP non inverter for living hall that’s next to dining and dry kitchen also cool enough.

Yes the installer checked the copper piping and said couldn't find any leak, he said if there's leaking the pipe will be oily, but he checked everywhere couldn't find the spot. Then he refilled gas and it started cooling again for like 2 weeks. Now it's not cool again 😢 Is it normal for my model to take quite long to cool down the room? My previous house had an old fujiaire 1HP and it performed much better than my Mitsubishi.

I will contact the installer again.
*
Is it the same installer, or did you try diff technician?

I had problem with 1 of my Midea Inverters a/c... called same fella fix twice also problem keep coming back. Third time I found someone else... and until now no problem..

QUOTE(-kytz- @ Mar 21 2023, 03:39 PM)
I'm thinking of replacing my very old 2007 air conditioner but my aircon repairer mentioned the pipping (?) is the thinner type and all the modern aircons are using much thicker pipes due to much higher pressure (like 2x more pressure than aircons back in the days). He mentioned it is possible to change to a thicker piping but needs a lot of hacking job as it is inside the walls.

Also, he also mentioned my place wiring has only 3 lines whereby the Earth needs to be used for the Control or something, I really didn't understand too. But basically there will be no earthing (But I live in a condo where there is lightning protection)

He did mention he installed 10 new air conditioners before MCO for other units at my condo which the same small piping and all, there are no issues until now.

My aircon at low fan there is almost no air coming out, I suspect the thermostat is faulty too as the temperature is not accurate. Plus a newer inverted type airconditioner may save me electricity.

But should I take the risk though? Any inverter airconditioner I could take a look at which might have lower pressure?
*
2007 probably using R22 gas. Answer is no, it is not up to spec for latest R32 a/c. Don't take the risk, anything happens you just going to pay more for installer to fix it. And if your a/c is still working fine, don't need to change lah. Yes, newer a/c is more power saving, but the $$$ to do it properly.. not worth the power savings.

Cheapest Hisense units. I own 3 of it. Haier I’m not using myself but so far no complaints also.

Hisense is good. Cool fast, and cheap. Noisier compressor compared to Panasonic inverter.

Unfortunately I had to replace my Pana 1.5hp R32 standard inverter just barely 4.5 years, due to gas leaking. Last year replaced compressor when I complain not cold, this year January not cold again, pressure dropped then they refill gas and told me not worth to repair, better replace it. March starting not cold then I have to replace it...
*
It could have been the pipes as well causing the leak and not the unit. I faced the exact same issue with my Midea 1hp inverter bought in 2017. Engaged aircon hero who failed to repair it. Called them twice. Useless. Then I found an aircon specialist who fixed the issue for me.

May I know which model do you get?

I'm thinking of cheap a cheap air cond for my guess room.

Cheapest most basic non inverter unit. I have 2.5hp, 2hp from 4 years ago. And a 1hp last year. The 2.5hp and 2hp beast are used sparingly. Maybe 2 times a week, alternating between the 2. Which means each unit sees 4 times use every month. It’s in living & dining area open space, no issues with cooling at all. Compressor is on the noisy side but I’ve installed it at a strategic area so no concern.

I just checked it was mitsubishi electric

Getting quote
1.0 hp  rm1550
1.5 hp rm1850
2.5 hp rm 3250

Price are slightly cheaper than Daikin. However the sales person is recommending them for the reliability.  I do know about the sales incentive. Might go for Panasonic or Daikin if mitsubishi reviews are bad.
*
I've got a Mitsubishi Electric (not MHI) non-inverter. AC is good. Compressor is a bit noisier than Panasonic -- noisier as in it is a lower frequency rumble versus the Para. The common theme regarding ME is that parts are not as easy to get versus Panasonic, Daikin & Acson.

But it is not as bad as Koreans, Samsung & LG parts are non-existent in the market and the Aircon man says you need to contact Samsung Malaysia or LG Malaysia.

My ME a/c don't see heavy use so I am not too worried about parts. Heavy use A/C is Panasonic...but if I were to choose today, I will go Daikin/Acson over Panasonic.

That’s me. I’m cheap. Hisense basic 1hp non inverter. Cold AF.

I have a mix of inverters and non inverters for different spaces and use cases. Guest room use few times a year no need inverter. Likewise for living room open space also I don’t need it.

Depending on how many total AC in the house. Buying basic AC and saving the funds and invest in solar is better long term. But for own bedroom sleeping I always advocate “overpowered” inverter for comfort. And buy a cheap Bluetooth logging thermometer with humidity level will help in understanding how to best set your own AC schedule. My AC always timer off at 4am when ambient temp drop to its lowest.

How do we best set it with a thermometer humidity level sensor?
*
Comfort level for humidity should be between 30% to 60%. Sometimes it rains, sometimes doesn’t.

I like to keep humidity around 55% when I sleep. Cool mode will do that quickly.

My AC works everyday, even on cooler nights where I’ll just set it on dry mode.

Again, it is best to get the thermometer and humidity sensor so you know what is comfortable for you. Very good investment to use your air con efficiently.

The one I use have logging so I can see the temp and humidity level from the night before and experiment with timer. Nowadays typically set timer to turn off my AC at 4am and by the time I wake up it’s just perfect.

I noticed my master room temp drops to its lowest between 3am to 5am, then gradually goes back up as sun rises. Logged it while I was sleeping in my guest room.

if ur room only needs 1.5hp but u need 2hp to really feel cold, i guess it is due to room is west sun facing?

Nope

1.5hp “needed”
I install 2hp inverter

One key difference is the 2hp will reach my desired temp faster.

A 200hp car and a 100hp car, both can do 100km/h speed. The 200hp car will get to 100km/h first. Unless it’s a Panasonic. Then it’ll get there last.

And with inverter, the compressor can slow down to maintain the temperature I want. so no such thing as overpower.

I truly, genuinely hate my Panasonic. I set I-autoX mode at 16C, my temperature sensor reads temp as 26.4C for the last 20 minutes. Basically Panasonic just take my command as a suggestion and it think I want to save electricity. Sadly I paid too much for this Panasonic inverter and I don’t have desire to spend money to change it.

Did you read what is i auto x?

It's basically temporary fast cooling. Besides from what I read, once it reaches certain temp (most probably set by manufacturer), it will auto direct the air flow upwards to prevent human over cooling. Why don't you use normal cooling mode if it annoys you so much?
*
Cool mode is even slower than I auto X to cool down.
There’s no power mode on Panasonic air con, unlike the old Panas.

Basically there’s no mode on Panasonic to give me what I want - max cooling. You’re saying the temp is set by manufacturer, then why bother giving a remote and temp setting. Give on and off enough lah.

I don’t know about you. If I buy an air con, I want it to function at the settings I determine.

Hi i want to ask for opinion.

I have a Mitsubishi 1.5HP inverter that has been serving me 10 years problem free. Yesterday it broke down not cooling anymore.

And i asked 2 technicians and they both said my pcb board is broken already and advise to just buy a new unit.

The reason given is that the parts is hard to find, expensive and take times on delivery.

What you guys say?

But honestly it a money  well spent

Try contact those PCB sellers yourself. Lzd Shopee a lot.

QUOTE(Benefon @ Feb 5 2024, 07:20 PM)
What is the model?
Daikin pcb can last 5 years
Panasonic after warranty or 3 years only

This I don’t agree. Daikin pre-York is utter rubbish. My inverter model spoiled right after warranty and aircon guy say the PCB RM4xx, he wanted RM2xx for workmanship. But had to wait for PCB at least a month. That’s when I changed to Panasonic inverter which was worse at cooling versus Daikin. This was many years ago. But this Panasonic no issues. Just not cold and power saving.

QUOTE(ZeneticX @ Feb 8 2024, 02:02 PM)
I only found this seller also but they are in JB... not sure delivery to KL need how much. GR series price seems to be 2k+, a bit over for me and havent include installation charges yet

BTU range for the 1hp airconds i considering
Mitsu GR series - 3,753 - 11,601
Daikin FTKU series - 3,700 - 11,600
Sharp AIoT J Tech inverter - 2,870 - 10,600
Haier HSU-10VXA22 - No info. Only listed BTU as 9720

Price wise Haier cheapest (1k+), Mitsu most exp (2k+). Daikin and Sharp in between (1.6k+)
*
I would avoid Sharp. Not that great, except that the outdoor unit is smaller than peers. Midea, Haier, Hisense I have had great experience. Many people don’t consider it because China mari, but truth be told these brands sell more AC than the likes of Daikin & Panasonic worldwide. Midea owns Hitachi and Toshiba.

I have Midea inverter. Solid 7 years now no issues except the yearly service. One unit did not work properly due to poor installation. Haier and Hisense non inverters working fine. Hisense cold as hell.
