I plan to have 1.5HP Inverter for my living room.
I have shortlisted to Panasonic, Sharp and Mitsubishi Electric.
Need advice and recommendation which to go for.
It would be a plus if it can help purify the air in the living room.

Coming here to learn about aircond from sifus for my new condo

Below are my current plan, and some suggestion to seek from you all

1. 1x 1.0HP inverter for master bedroom

2. 1x 2.0HP inverter for living room+dining
I also plan to have the aircond install at balcony wall, rather than sofa/TV wall so it can be blow directly to dining area as well
The only concern is the balcony wall are facing sun so not sure if this will affecting the temperature sensors for the A/C
Else I have to split to have two A/C for living room and dining

3. 2x 1.0HP non-inverter for two bedrooms

4. Utility room (size 1850x2150) to convert into working space to work from home, plan to go with 1.0HP inverter
Since it's so small and no A/C piping/power ready, should portable A/C to be consider? How about the electric consumption?

5. Should all these A/C have individual compressor? The allocated space for A/C was 460x1900

The actual increase in efficiency due to shading is not expected to exceed a maximum of 1%. Actual daily and seasonal savings in energy will be even lower. The findings of this study suggest that shading alone, without evapo-transpiration, is not an effective measure to improve A/C efficiency or reduce electrical demand.

3. 2x 1.0HP non-inverter for two bedrooms

Consider changing to  Midea inverters AC  ...    cost not too much vs non AC

less noise  from  ON/OFF  operation
save some power .

#5 You can fit 4 compressor into what I assume is AC ledge with standard bracket right? 5th one is on balcony wall.

#1 #3 #4 you can get inverter since its not expensive.. UNLESS 3 (two bedroom) is used as storeroom nobody sleeping one.
Inverter only 1099 for Hitachi RAS-X10CJ on Lazada.

#2 2hp inverter may be a bit overkill if its not that big space. The ODU at balcony (assume there is no JMB or bylaw preventing this) should be installed where it can be shaded if possible. Although the ODU is weatherproof (and it rely more on moving air to cool) but long extended exposure to sunlight UV will make the paint and plastic parts (eg fan cover) brittle in a few years.

The difference in shaded or baked aircon ODU is ~1% - http://oaktrust.library.tamu.edu/bitstream...IC-10-10-52.pdf
This is because the ODU fan cools by air movement (it moves a lot of air). Erecting some sort of homemade "shade cover" using coregulated plastic sheet is only for aesthetic purpose (sacrificial protection) to prevent the paint from cracking up from the sunlight UV only. Though as you have to leave the fan opening "circle hole" cut out this will do nothing for the fan cover w.r.t UV exposure ya.

#5 yes individual is better for MY. Anything goes wrong the others can continue to operate. This is not SG where they only allow you to put one big ODU feeding 3-5 IDU.

Thanks. For compressor I will go with individual then
On utility room, will need to see how much costing to add the piping and electric point as well

2. My living+dining until kitchen is 3150x9850, so 1.5HP should be sufficient? Piping and electric point guess also need to extend and cost to include.. I have attached my layout here

Yes, that item 5. is A/C ledge, will try to put all over here including the living mainly due to JMB, however not confirm yet

3. Two bedrooms mainly one for store and one for standby for guest if there’s any, so mainly will not be use. Will have price comparison and see if budget allowed

2.5hp Full size cassette with inverter I think hard to beat this. Yes for this size have to see R410 clearance coz R32 cassette cost a bomb
Price performance pretty good

RM2929 York 2.5HP 26500btu Johnson Controls DC Inverter Ceiling Cassette YCK5J Series YCK5J25AAS (https://www.lazada.com.my/products/stock-limited-york-25hp-johnson-controls-dc-inverter-ceiling-cassette-yck5j-series-yck5j25aas-ysm5j25aas-r410a-i518496571-s7504794276.html)

PANASONIC INVERTER R410 BIG CASSETTE S-21PU2H5 will cost RM3910.

For this huge size inverter is a must.. You can save the 800 or so on non inverter but OPEX (TNB bill) will milk you slowly.

Hi guys wan ask something, technician coming to do installation for 3 split ac for 3 rooms.

I heard the installation process is very crucial to the overall functioning of the aircon, anything i need to take note of ? Or the technician sifus will take care and check for leaks / pressure everything during and after installation ? Coz first time installing so very green in this, scared after install finish they just balik.

The drain pipe should be installed so that the outdoor side (drain side) becomes falling slope (1/100 or more) and do not make trap or peaks per https://www.mitsubishielectric.com.au/asset...RG79Y376H01.pdf

appy for seda 2.0, after 1 week, lazada email the voucher with 1 week validity.

didnt know lazada has delivery charges. afterall its still cheaper

i am replacing the old panasonic split R22a to inverter air cond. is the copper piping need to be replaced ?

can I simply ask for replacement of copper pipe ? since its included in the "new installation" ?

hisence 2hp inverter wall mounted rm2200
daikin 2hp inverter wall mounted rm2900
I need 6 units....if I use hisence i can save rm4200.... but no confidence on hisence...

hi everyone.. now what brand good for air con ya? panasonic or daikin.. in term of reliability..

I have been reading your airconds recommendations, thanks for the great recommendations so far!

I would like to have a cassette aircond recommendation as well, but I have a rather niche requirement.

1. Preferably 2.0HP, but am willing to go from 1.5HP to 2.5HP.
2. Inverter
3. R32 is a plus, but R401A is fine as well.
4. Must be WIFI internet enabled to be remotely control via App. Or smart control, for lack of better term.

The reason for the the smart/internet requirement is because I would like to integrate the aircond into my smart home system. As long as it has a somewhat open API, I can tape it into my home assistant network. Besides, my family member have tendency to leave the aircond on when they leave the house.

I have experience with Panasonic WIFI control (Smart Cloud), but it is a wall mounted unit.

Thanks!

Hmm Pana previous batch alot seem to have the same problem = https://forum.lowyat.net/topic/2005961/+40

Nowadays it's hard to tell because even in same brand, series wise can differ a lot. Sometimes the previous gen 1 R32 inverters are better than the newer gen 2 R32 inverters, spec wise.

Daikin you should not buy the cheapest range. 2nd up cheapest is OK.

JCI Hitachi I can say the previous batch CJ series was designed with very good spec.. CKM lower spec but still reliable.. there are 1hp inverter R32 for 1099 from Lazada which is actually a good deal as the prev range CJ is better btu spec than current CKM spec. Properly designed AC for that price, 2/10 warranty.

Mitsu Mr Slim is OK. Between JP JR JS see spec sheet cos some series better btu.

Sharp also OK for value for money reliability, AHX9VED2 series not bad, also 9700btu design. Newer AHX9XCD 9200btu design.

There are certain scenario like 2hp cassette that it is more optimal to use a R410 inverter simply because that price only can buy a R32 non inverter. And the R32 inverter simply cost around 800-1000 bucks more which is hard to ROI even with inverter savings.
