Guy, I am also considering the smile series.
The electrician brought up the idea of having 2 compressors instead of one. But I don't really understand why it is better (my Chinese is bad). He mentioned something like it will be colder and if one compressor breakdown, still got one more working at least for the other rooms. Correct me if I am wrong please.

So if I follow his suggestion and go for 2 compressors (my house and 3 br, 1 living room), will it look like this?

Eg. 1:
Daikin smile series system 3
- this will be for the 3 rooms

Daikin smile series system 2
- This will be for the living room (2 Aircon units)

Or....

Eg. 2
2 x Daikin smile series system 2
- One for living room and a smaller room
- Other for MBR and another room

Is that correct? Any other way to configure?

If I go for 1 compressor, I can just go with a Daikin Smile series system 4. Will that be better?

Yes, I got saving of nearly 20% electric bill from 3 ticks to 4 ticks. Imagine the newer model which got 5 ticks. Average 40-50 buck saving per month and amount to 600 per year. You will get saving from 18 months onwards if you spend more $900 for 5 ticks.

The salesman is smart. The setup is ideal also. It helps you save more and more flexibility in ur AC usage. If the cost is ok, I would recommend this setup of 2 compressors.

Another plus point is you divided your load into 2 compressors and so less chance of getting spoiled.

Bad points - will cost more in maintenance if you need to top up gas. because you be paying double for it.

Oh please take example "1" if your bedrooms are mostly occupied and tend to use AC more frequently.

take example 2 if your "Smaller" room is less frequent used.

If cost is a factor, take 1 compressor, cooling efficiency will drop aka, take longer for you to cool down the room or living room which you will drop the temp to make it cooler and in turn you use up more power and increase workload for the compressor. Can be done but not advisable unless ur taking 38VA compressor which also high power consuming.

Hey Gentoro, thanks for your Suggestion.
So based on your use-case scenario, I am most likely going with the 2 compressor option.

Question! If I am only going to fully use MBR and one of the room's Aircon frequently (2 rooms in total), do I put them both on the same compressor or spread them out between the 2.

I actually have 3 systems in a three room setup:
Living - two units
Study - one unit
Two bedrooms - one unit each

Living room has a unit which is a standalone and shared one. Overkill? I only use what is needed depending on the guests and my energy bill is low, especially after using a 4 tick Panasonic.

Get them together in 1 compressor> If suay suay spoil, just 1 compressor or frequent servicing on just 1 compressor.

Thumbs up Nat aire

I bought a 5 tick LG A4UQ26GFA2 System 4 from the Nat Aire during the weekend. Delivery and installation was arranged within a week. Their employees were very polite and patient as we discussed routing of the piping. They came in the morning and completed the job within the day.

A few days later, air coming out of all the fan coils was not cold. I called them up on Monday morning and the same installation team came in the late evening and problem resolved immediately

I highly recommend DIYappliances /Nat Aire builder. Good product 5 ticks system, reasonable priced and fantastic installation and after-sales service.

I'm have the same unit, having the same problem of aircon not cool. Did a test some months back, seems like there's a leak somewhere. Top up gas will stay cool for a few months, then back to same problem.

Weighing my options now, last resort is replace the whole system, but I'm reluctant coz current piping runs through hidden panels everywhere! Plus the leak means I can't reuse old piping.
Same here, lasted about 3 months and had to do a top up today.

Anyone experienced using aircon leak stop sealants? E.g. here's a link:

If yes, how's the result? Any contact and how much did it cost?

Hi guys, my aircon installer installed the trunking already. May I know how to check if he used G22 and 1/2 inch insulation?

1/2 inch insulation means the insulation is exactly half inch thick? Is the entire diameter or only the thickness inside?
