Both also okay. Gree was the top CN brand.
Past series not that great but the latest R32 inverter queen is not bad.
The Gree inverter apparently can run super slow mode btu (~10%) when target temp is achieved; Sharp one slowest mode btu ~25%.

Sis here actually. You're most welcome!

Maintenance basically all the copper pipes for gas/liquid are sealed piping, nothing much to do unless leaking gas. Once in awhile hose down the ODU fins.

Usual cleaning of filter/dry vacuum n soft brushing the IDU, pretty much standard across all brands.

Proper installation especially the angle for drain pipe for water, whilst it is the cheapest component, if pipe sagging (horizontal runs) can start ponding water n algae inside. Enough slope angle (1 in 100) drop must be used so it flow correctly. Steeper angle is better, but may not be doable due to space and other constraint.

No harm, your coils will be cleaner. Just that it may reduce airflow abit depending on the filter pass through. Worst case is just need to run the IDU fan one speed faster (with additional filter). Will be easier to clean coz replacing filter is usually easier than vacuuming out the coils.

Hello Sifus..

I humbly need ya'll to shed light on my current situation.

I'm contemplating to buy another air-conditioner for my room.

My current Hitachi RAS-EH10CKM (a 9000btu/h air cond) provides insufficient cooling during daytime but adequate during night time.

So i need advise to get either of the following air conditioners:-

1. Panasonic X Deluxe CS-XPU13WKH (1.5hp) = RM1719.00
2. Daikin FTKH28AV (1.0hp) = RM1743.00
3. LG Dual Inverter Deluxe S3-Q12JA3WA (1.5hp) = RM1599.00
4. Gree Queen I GWC12ACC-K6DNA5A (1.5hp) = RM1490.00

Now, I am not replacing my current Hitachi Non-Inverter by getting a new Inverter unit as it could not be relocated to other rooms in the house due to it being too underpowered. My plan is to add another unit in my room and maybe i'll switch on Hitachi from time to time just to give it a run but i'll mostly be using the new Inverter air cond.

Is the Daikin (option no. 2) okay? As it's a 1hp unit but having a significantly higher nominal btu at 9700. As mentioned previously, my current 9000 btu/h Hitachi is only insufficient during daytime.

For context, my usage is setting the temp at 27 Celcius and circulate the air with a fan. I use it mostly during bedtime and naps on weekends.

The LG and Gree could drop down its btu to 2000btu and 1365btu respectively compared to the Panasonic and Daikin. The Panasonic on the other hand has a much higher btu to spare should the necessary situation arise, plus i am quite fond of the Panasonic brand as my brother's 2005 Panasonic was still blowing ice cold until it was replaced last month (March 2021) to item no. 1 above in an attempt to go green with R32 and save electricity.

I'm so confused but one thing for certain, i will not spend >RM2k for an aircond (for my room that is..).

Fun fact, i've even considered a Midea 2.0hp Inverter (Xtreme Save) as its around the same price but the minimum btu is roughly around 7k++ so its a no.

I'm all over the place.. please send help... most grateful to those who could give an input on the matter at hand.

You might also consider other stuff :

1. Gap below the door big? Consider the door seal(brush or rubber type)
2. Consider tint with high infrared rejection for window
3. Consider window seal for window gaps
4. Long time no service aircon? Consider service.
5. A lot of heat absorb by outside wall? Consider light color paint if the wall is dark colored or wall insulation.
6. Room on top floor? Might want to consider roof material or insulation.

Okay so...

1. Gap between door and floor is minute (about 3 cm)
2. I have 3 windows [since my room protrudes out, each window faces east, north and south (all 5ft by 5ft)].. no tint so far, but i like my room bright hehe
3. No window gap actually since i've just replaced the window framing / pane
4. Air cond was bought new in November 2020.. i clean the filter once every 2 weeks.. i think the dust is still okay as its not noticeable on the coils
5. Yes tonnes of heat since the window that faces North gets continuous sea breeze and its overlooking layers of zinc (as beneath it is our verandah)
6. Roof insulation is new as well.. one of those aluminium coils.. since i had changed the roofing on September 2020.

I honestly think i bought an underpowered Hitachi unit (1.0hp non-inverter)... my room measures 17ft by 14ft btw.. ceiling height is about 11ft.. but my ceiling is close to the roof since my room is an addition from the initial house, hence the sloping roof means my ceiling is about 2ft to 6ft of the

3 cm is damn big. you should definitely install the door seal/skirt

you have 3 big windows 5x5 , plus a big room on 1st floor ..
in hot afternoons even a 1.5 hp will struggle. not sure what temp setting you normally like .
you need to position the indoor blower unit as near to where you want it coolest .
i have the same issue with a big long room .

you need to install window tint with maximum TSER . with higher VLT . more light pass and high IR block. or do a combination on the windows.

3cm gap on the door is excessive ... there are some door seal product on shopee that narrow this.

i like the new Midea invertor AC. cos you can do localise cooling . cos the temp sensor in in the remote.
reason you cannot cool that big room, plus your power cost will be higher . so localise cooling is better option . just cool the area you want coldest.

Aside from the AC sizing, the heat transfer into your room via the wall and zinc roof could be the problem. If you ventilate the veranda (experiment with table fan, stand fan, every portable fan u have) it should bring down the heat load from there I guess? Because 1.0hp is not able to cope with all the excessive heat. If ventilating the verenda (somehow) cools down the temp of the verenda area then you can consider wall fan or exhaust fan depending on shape and profile of verenda overhang, but since the verenda is below your room it should not be that.

Currently how is the heat profile in your room> is it using roof tiles? Is the room excessively hot (common top floor issue) due to poor roof ventilation?
Coz I have seen 1hp AC struggling to work in a small room because it was on top floor in a DSL, external wall seems to be heated from the evening sun as it was an end lot.

Oh sorry Sis.. ok, hopefully the shop come with good installer.. anyway thanks again for ur reply.. =)

Well its quite mafan to install a window tint since its an extra cost on top of my need to get another air conditioner.

Regarding your suggestion on door seals, i've just purchased a brush type seal..

https://shopee.com.my/2-Pcs-Seal-Gap-Wood-G...9086.5076346938

After surveying around my local shops just now.. i think i will step up and get a 2.0hp air conditioner to solve my problem once and for all.

Between a Panasonic X-Deluxe, a Midea Xtreme Save, a Gree Queen I and a Haier DC Inverter (all 2.0hp).. which one should splurge if i prioritise quality, cooling capability and reliability? My house is near a beach btw.. so the a toughened ODU is essential.

Thank you so very much for your suggestions all these while.. extremely grateful for it.

Wow thank you Sifu for replying to my stupid predicament

My roof type is the typical zinc but i made sure it was a thick one (the zinc factory asked me to specify the thickness from 1 - 5 and i selected 5). Ha!

I would categorise my room as a desert. Extremely hot during the day... extremely cold in the early hours of the morning. I think the gap between the roof and my ceiling is quite narrow since my room is an addition to the original house.

My room is facing east ultimately.. but even at 7 p.m. when checking my handy thermometer, it displays roughly 31 celcius ambient.. and turning on the air cond takes about 2 hours to get it down to at least 29.0 celcius.

So i have now decided to solve my problem once and for all by purchasing a big air cond (a 2.0hp inverter) and the choices are between a Panasonic X-Deluxe, Midea xtreme save, Gree Queen I and a Haier DC Inverter. I have heard great reviews about the products listed and my priorities are cooling capability > reliability & quality > electrical consumption.

I've avoided Sharp (i know that Sifu is quite fond of this brand) as my house is next to the coast and the aluminium heat exchanger that Sharp uses wont survive the brutal condition (aluminium fins cant easily be welded when fixing leaks compared to a copper tube & Al fin combo based on my research).

So once again thank you for the reply and i hope to finally solve my problem.

Yes this was exactly the problem with undersized AC in my friend's room..on any sunny day we were really sweating indoors even with the AC on full blast.

Between the choices..as long as the ODU fins has anticorrosion coating (usually blue/green fins) will work for your situation.
Considering cooling power and reliability-wise - I'd be inclined to the Pana or the Gree Queen R32 ones. 2hp will not be overkill given that the heat load is very hot.

The first priority is to cool the room full blast so you also need to consider not only nominal/rated btu, but also the turbo btu (redline) of the models.
The electrical consumption part, most inverters will be at least 4-star ST so no need to worry too much on that - savings will kick in only after the IDU has reached target temp.

Your room could have "top floor effect" since the roof is made of zine. Is there a layer of ceiling under your zinc roof? If yes, you can put some insulation material at your ceiling board to reduce major heat transfer from the zine roof.

Radenshield (radiant barrier) can be installed as insulation on the roof.
Cost only a couple hundred per roll. Pretty lightweight so easier to install. Rockwool slabs are heavy stuff and need more supports.

https://youtu.be/d-ShAiclBt4

Important for it to work, it need air gap between the roof and radenshield to work.. so installing it to the bottom part of roof battens will provide the airgap necessary.
Theres 3 type of heat transfer, radiation conduction n convection.

Conduction is the transfer of thermal energy through direct contact. Convection is the transfer of thermal energy through the movement of a liquid or gas.
Radiation is the transfer of thermal energy through thermal emission.

So in short with the radiant barrier (with air gap) essentially solve the conduction (air gap) n radiation (foil reflect the radiant heat back); convection little bit since the foil sheet minimise air movement.

the window tint you can DIY ,
i cut to size and stick it on the window using 3 pieces of tape at the top. the reflective surface face the sun/outside. then use soapy water to stick it on , done.
i did not follow the normal way to install. ie not remove the protect film.
below are the good ones. and i estimate you will spend about 120- 150 RM in all . its totally worth , reduce heat , less warm room , less power usage.
go for it bro.

https://shopee.com.my/product/88886303/2103753173

https://shopee.com.my/product/276297222/7543513267 this one is better quality ,
i bought both , i bought first to test , than bought again . for my whole house. spend only 120 rm . DIY .
Imagine those who fit their cars tint for more than 1 K

i will go for the Midea .
reason is if u scan shopee .. you will see they are one of the top sellers .besides the other known reasons .
comes with 2 years general warranty and rust guard, ionizer , Follow me, etc,,,
see the feature s you get ..

https://www.lazada.com.my/products/klang-va...7P1R8C&search=1

the Gree is also a good AC ' my only concern is their poor sales .

Gree was no.1 brand in CN home market until covid happened, Midea overtook them because midea had better online n distribution channels

Gree earlier series they brought in basically mostly were non inverters and on paper spec those earlier series spec wise kinda sux when compared to the competition, thats why poor sales in MY. However the Queen R32 inverter spec wise is pretty good.

yes agree about gree .
i bought 2 units 6 months ago . using daily now and think its just as good as the other top brand.s

another possible reason for the poor sales is cause of the master distributor HQ being in sarawak .

hi all , would like to check is this a good deal for sharp aircond? or is there any better option around this price range for other brand eg daikin

Just a quick one, if money were no object, what's the best AC brand/model in Malaysia? I'm referring to 'normal' split models.

Asking for a friend.

I had always wondered why aircon cover has to be in white?! hahaha, why cant they make in color hence customer has more choice in fitting at their local setting?

I know, some manufacturer in the past did try some colored strips and some lining in color but thats about it!

Meanwhile, my cousin is looking for a portable aircon, I dont have much experience in it, seeking those who had experience in it to share, on what to look out for, other than spec.
