Oh, you mean you have confirm on Mitsubishi and piping done up without installing the fancoil and compressor unit? What piping, G23 and thickness of insulation used?
Yes piping installed 1st and fancoil/compressor to be installed after 2nd coat of paint done.

I'm not sure how thickness of the installed piping has anything to do with whether I'm able to switch brand/model of aircon ... it should be more an issue of fancoil size, yes? Also, there is a cut-out in the false ceiling / L-box in the living room meant for the 18k BTU 2-tick Mitsubishi unit and a cut-out in the L-box in the master bedroom meant for the 9k BTU unit. What I'd like to know is, whether the equivalent BTU Urusara and/or Envi units - should I choose to upgrade from 2-tick Mitsubishi to Daikin Urusara or Envi - will also be able to fit in those cut-outs.

I think Urusara will have more ticks compared to Envi, probably you can go down to Daikin Proshop to understand more before deciding.

To F3Rm1nat0r,

Daikin or Mitsubishi Electric system 1 is quite good.

To amazingone,

For the non-inverter, Daikin is using the R22 gas.

looking for a system 4 (living room and three bedrooms)

is Toshiba a good choice? seeing that their compressor is made in Japan? tested it at A** B*** and it really feels cooler than the Mitsubishi (2 ticks)

anyone using the Toshiba? any problems with it so far?

Hi Precise, I got myself a Toshiba Sys 4 with the following:
1 x RAS4M26SACV~INVERTER
3 x RASM10SKCV~INVERTER
1 x RASM22SKCV~INVERTER
1 x stainless steel bracket
1/2" sys 4 (class 1)
Copper 22
Drainage pipe 16 mm
2 trips installation

Gain City $4569 (free gift of $200 Capitaland Vouchers) Got it during a sale at AMK showroom earlier in Feb.

Precise, why are you considering Toshiba Aircon? You heard any good reviews about it?

Thanks for the breakdown.
Went to GC amk today.
Quoted
Same config as you for tosihba at 4619
Comes with 5 years warranty free with a cap which i can't remember now.
Add 159 to make it unlimited coverage.
Add 150 for bracket
Add 250 for the best installation material.

Total 4619 + 159 + 150 + 250

Think you got a good price.
Now exploring option of Daikin.

Reason for tosihba is
1. Made in Japan. ..except fcu
2. One of the highest btu for sys 4.

I'm in no hurry. ..
2 out of 3 rooms are still working with existing sharp sys 3.... installed 14 yrs ago.
So c c look look now.

Seems like the parts reliability for Fujitsu may not be true, probably I should try Daikin instead since they should be the expert in air conditioning. :s11:

daikin is good. i have been using for more than 16 years already.

only came in here because of constant leaking from my aircon unit.

sometimes leak when switch on, sometimes also leak when it's off lol

dunno wtf happen.

thinking maybe it's due to old age liao.

looking forward to change to new system 3, i'm also keen in the silver envi too

looking for more reviews before i settle it :D

Brother, the fancoil leaking is only due to the choke in the drainage piping as it will build up the gel as times goes by so you might want to ask the servicing company to do a check or if you can DIY, you can actually buy the solution by Mckenie to pour down the drainage pipinig.

Most of the times, I do general servicing including the piping choke clearing myself so only approach the servicing company for chemical washing of the coil.

I have been using National or Panasonic now for many years as they have the ionizer built-in so thinking want to change a different brand for a try. =:p

Hi all, one of my FCU doesn't blows out any air anymore, though the fan is still running even at its highest fan speed.

What could be the problem causing it? Is the FCU faulty as my other two FCUs are still working fine.
Thanks! :)

Ok all the best as u hunt for the most suitable Aircon, precise!

It's true that I was pretty attracted to Toshiba as its compressors are made in Japan. But I'm not too sure like is it really good..

I see, it depend on where is the leakage and if water is leaking along the piping lines then there maybe a leak in the piping and nothing to do with the Air-con.

If the leakage is on the bottom of the fancoil then it is due to the build up of gel on the drainage piping which cause slow movement of water flowing thru the pipe so water will build up and cause leakage. Maybe the servicing company you approach is not so professional.

For Daikin, get the Silver Envi will do, you must request G22 for the Gas piping and 1/2 inch insulation. Compare a few more companies before deciding.

Some noob questions here, if I want to get a Mitsubishi Sys 3, which dealer is most reliable?

Some portions of my existing aircon pipes are hidden behind concealed panels, will that increase the cost of installation?

G22 or G23 refers to the thickness of the gas piping so G22 is thicker than G23 as the number goes smaller.

Below is the blog page you can read up a bit, I also read up from there which many air-con companies got promotion on free upgrade of gas piping from G23 to G22 like the Daikin ProShop.

Just checked with another supplier . He mentioned that Toshiba is good but its design is not suitable for Singapore. Reason being the cooling fins are dense and accumulate dust much faster and can cause choke to drainage if not maintained regularly . Need to visit and validate.
