Hi,all.
Need your advice.

I'm moving into a resale condo very soon once my tenant moves out. As the existing non-inverter split aircon system (2+2+1) is very old, would like to replace with a new system.

My floor area are as follow:

Master bedroom - 17m2
Bedroom 2 - 13m2
Bedroom 3 - 13m2
Hall & dining - 38m2

Usage pattern are the 3 bedroom to be turned on at night and the living and dining as required.

One contractor proposed the following 3+2 system:
Bedrooms - Panasonic CU-3S27MKZ + CS-S12PKZW x 1(Master) + CS-S9PKZW x 2 (Bedrooms)
Hall & dining - Panasonic CU-3S27MKZ + CS-S15PKZW x 2nos

Will be re-using existing piping as so far no problem with the aircon unit.

Price quoted is $5,040.

Question
1) Is price reasonable.
2) Also, should I stick to 2+2+1 system instead.

To Misran,
This price is reasonable.
For 2 + 2 + 1, the benefits is that your master room is single system, so when one compressor is down, u still have the other 2 for usage.
For ur current proposed setup, all 3 rooms share the same compressor.

Thanks for your prompt advice, terumo.

In your opinion, 3+2 system is okay?

For my scenario, would there still be comprehensive warranty for the 1st year? Also, anything I should emphasize to the installer since they're reusing the piping for a system with a new refrigerant,e.g. cleaning the pipe, leak testing,etc?

To misran,

U can pay additional charge to get a pressure test done to confirm the status of ur piping before installing the aircon units.

Hi,

Need some comments from the aircon guru here.
I intend to replace my aircon units

Was quoted the following

Daikin Inverter
Model : RKD50BVM / FTKD50FVM
Cap : abt 17K BTU
Single unit for the hall
Cost : $1,850

For my 3 bedrooms
Model : 3MKD75DVM / FTKD25DVM*2 , FTKD35DVM (master bedroom)
Cost : $3400

So did the shop treat me as a Robert or the price is reasonable?
of cos workmanship will also play apart

Thx

Hi, how do you calculated to 8.5A? Can teach me coz I wish to look at other brands too. Thanks!

Most brands offer system 4 which is applicable for usage in new & old HDBs. Only the 4A38 cannot be used for old HDB whereby the power allocated is insufficient...

Yours is reuse or new piping? Condo new piping required hacking and such... which is cheap for the price. most prob is reusing the existing pipes.
And your daikin Aircon is an old model using R22 refrigerant. New model is 3MKS75

Pointless bro. Upgrade to highest quality for HDB or condo would be 3/4inch insulation & 22 gauge piping. Can last u min 15 years with proper maintenance.
Aircon fancoil warranty is only 1 year by agent, u extend to another 2 years, total 1 + 2, how often an aircon spoil within 3 years? At most if spoil, labour and parts cost you 150+- each....

Hi,

Any recommendation for sys 3, New Bto flats.

Local brand, pana, mitsu, daikin, Samsung?

Best place to buy and costs?

Tks. ;)

The very first thing you must ask yourself is whether you are using the aircon on a heavy usage. IF yes you should go for inverter which is more expensive but can save you money in the long run.

This article on inverter aircon vs non inverter aircon might help you make a better decision:

Anyway from my understanding, Non inverter not available for sales by NEA anymore... Kinda due to issues of energy consumption

to noelnoel,
Most brands catalogue will state the max running amp.
But usually the system will operate at a amp lower then the max.
