Anyone here have experience with a multi split air-cond system?

I'll probably need at least 6 air-cond units for my apartment and don't want the hassle of looking for ways to accommodate 6 compressor units. Been looking on the web and with Daikin (the only brand I know that has multi split), I can get away with just 2 compressors.

Daikin is famous for multi split which many singapore HTC also using Daikin multisplit unit due to restriction by gov. My relative house is using it, so far no issue. But the weakness is once outdoor breakdown, all aircon cannot works. but if you have 2 compressor then should be okay la..

Thanks for your reply. If you don't mind me asking, has the outdoor unit ever breakdown in your relatives' place?

Was hoping to get some feedback in relation to AC size. This is my unit (around 1,700 sq/ft in size):

» Click to show Spoiler - click again to hide... «


I'm pretty sure that all bedrooms and walk-in will use 1 HP AC each. Would love advice from the guru's here in relation to the AC for the living and dining area:

1. Preferably, I'd like to only have 2 AC units (although I'm open to suggestions)
2. The AC at the dining area, preferably should be able to also cover the open kitchen

Can both the living and dining areas use 2 units of 1.5 HP AC's each? Or better 1 HP in living and 2 HP in dining?

Thanks in advance for any feedback.

There is no define answer. This all depends on the size of the room concerned. For example, most of my bedrooms are 1.5hp. My master bedroom is 2hp.

My living room is 3hp and my dining is 2hp. But that's because it is reasonably big and surrounded with glass!

As per your living vs dining, I assume they are open concept? In that case you have to make sure the total hp can cater to the total open area. Also think do you have a lot of glasses? Where do you spend the most time? If you spend more in living (most people do but you need to know yours), then use the higher hp one in living room. In this case that would be 2hp in living and 1 hp in dining. Unless you use your dining for work or sitting there for a long time dining room should use less hp if you have to.

The moral of buying air-conditioning unit is don't buy underpowered. It is ok to buy higher hp if you can afford 😬

QUOTE(blanket84 @ Feb 9 2021, 01:18 PM)
Are you sure a total of 3hp is adequate to cover all those areas? I uses single unit of 2.5hp for my living & dining and it was barely adequate.

If 3 hp is adequate, I think 2 x 1.5hp will be the better choice, cost wise. Place them one in living area and one next to dining area where you would probably use the most. Use ceiling fan to assist the air movement to reach other areas. And better buy non inverter since it is an open space.

And for your master bedroom, i don’t think 1.0hp is adequate based on the room size (relative to the bed size). My room is almost similar size as yours and I am using 2.0hp in my bedroom.
*
Appreciate the replies.

Living & Dining areas:
Yup, I plan on having 2 AC units to service both these areas. Just that was unsure in relation to the HP mix i.e. should put equal HP in both areas or have a bigger HP unit in the dining since it's a bigger area (cover dining and kitchen)?

This is an apartment/condo so there are not many glassed areas (only balcony and kitchen exit). Think I can get away with 1.5HP in the living and 2HP in the dining?

Bedroom
Ok, will have another look and do a bit of research. I'm currently sleeping in a room slightly smaller than that and with a 1HP unit, am quite comfortable with the temperature, hence the initial thought of just having a 1HP unit for rooms.

Generally, I plan to get multi-split units because looking at the space, I'll probably need at least 6 AC units, so can have only 2 compressor units which will be easier to hide. Only issue would be the limitation to only Daikin. Don't think anyone else offers the same, I think.

You should think how much time you spend in kitchen and dining vs living room. I can tell you that my wet kitchen is not air-conditioned and I have 9 air-conds 😬

Unless you really got no choice in terms of space don't get multi split aircond. First is single point of failure. If compressor has problem multiple units can't be used. Second, you can't upgrade easily to another brand unless you do wholesale changes again. Third I am not sure if these are more expensive than single split as I have not looked at them.

I'd say living and dining/kitchen split to be around 50:50. I don't plan on having separate dry and wet kitchen areas i.e. just 1 kitchen that will open up to the dining, which was why I was thinking of having the most powerful AC unit servicing these 2 areas.

I'm inclined towards multi split because my new place is a relatively old condo, so no dedicated AC ledge. The compressors will have to be placed at the balcony area. Opting for multi split is an aesthetic thing more than anything honestly.

Your two points are perfectly valid, although I'm basing my experience on the AC's that I've owned before and I can't recall any failing to such a degree that it was rendered unusable. Maybe I was just lucky. Looks like I'll have to do more research on this subject.

In relation to the cost, I believe it is cheaper when compared against single split, especially on the higher HP levels.

Good analogy bro, now you've put so much thought in my mind I think I'll have to relook at my plans/budget.

Although to be fair, get the wrong woman and you'll be lucky to make it past 50 tongue.gif

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.

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.

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
*
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.

Just a quick one. Which top of the line AC would you recommend between these 2? Panasonic or Samsung?

Thanks.

Cheers fellas. Would you recommend any other brand or would it be safe to just stick to Panasonic?

Just a quick one for all the sifu's in here. I'm planning my apartment reno and just need a bit of feedback/guidance in relation to planning my air-cond purchase.

My living and dining space area is a fat "L" shape and floor space is around 511 sq ft with average height ceilings of around 2.5 to 2.6 m. Based on calculations, would 2 air-con units of 1.5 HP each (1.5 HP x 2 units) be good?

Appreciate any feedback and thank you in advance.

sifusss. need some suggestion

where can i get AC + ceiling fans - planning to get 4 units ac inverter = panasonic or daikin (2.5 + 2.0 + 1.5 + 1.0) together with KDK ceiling fans (6 units).

is there any place can get good deals since purchasing all these together?

thanks in advance.

If you don't mind some work and are purchasing a 5 star AC unit, might as well buy separately from Lazada/Shopee and utilise the Save 2.0 RM200 discount for each AC unit.

You'll need multiple TNB accounts though i.e. your own, your dad, your mum, your brother, etc.

woah can save about rm800 in total. but the multiple TNB account is the tricky part.  confused.gif

ill try and see. thanks for the tips sifuu.

You can use other people's account so long as they've not claimed for the Save 2.0 before. So ask your uncle, aunty, friend, etc.

Everyone in my family has a place of their own so I'm quite fortunate that way so can use their accounts.

I'm getting the Panasonic X-Premium so the RM200 saving a unit goes a long way when you need to get 6 or 7 units.

Panasonic XPU, if more budget than XU.

Panasonic air-cond user all my life. Lasts long and never had any major issues (issue only because I never maintain properly).

Currently using the XU model for my relatively new place. Sometimes I can't believe when I look at the electricity bill. 5 star really makes a difference.

Get a Panasonic, install it properly and enjoy.

Hi Sifu, I need some advice. Currently, I’m using a Daikin non-inverter 2.5HP aircon for the living room. It worked fine for the first year, but starting from the second year, it keeps breaking down. I’ve already repaired it three times, and more than RM1000 has flown away. Now it’s broken again.

I’m thinking of changing to a new unit. Should I go for 2.0HP, or stick with 2.5HP? The 2.5HP is cold enough for the living room, but my electricity bill shoots up fast. My house is a standard double-storey terrace with an open dry kitchen concept.

Normally, I only turn it on for about 2 to 4 hours per day during weekends. Also, which brand would you recommend? I’m really not happy with Daikin — the unit im using keeps giving me problems, and the design seems faulty. Some plastic parts inside even melted.
*
I'm not an expert but just sharing my experience. Got myself Panasonic Inverter 5-star energy rating air-conds for my whole apartment.

Reliability so far so good going on for 3 years, just normal servicing. More importantly are the savings on electricity bills.
