Toshiba Air-con

Hi everyone..

Air-con noob here.. Am planning to get an air-con together with my flat reno starting in 2 weeks time... Have been shopping around and decided on the Toshiba brand.

My original intention was to just air-con the master(4m x 2.9m x 2.5m) and common bedroom(3.9m x 2.9m x 2.5m). I got a quote for a System 2 (2x9000 btu) at $2500 + installation + metal bracket.

Lately, i decided to aircon my living room(6.3m x 2.95m x 2.5m) as well. However, when i check the quote again... it jumped by over $1k. System 3 (2x9000 btu + 1x12000 btu) is $3550 and $3650 if use 18000btu instead of 12000btu. I was expecting an increase of between $500-$600 at most so i like to ask all experienced bros here.. is this increase of near $1k reasonable and what else could have changed beside just adding an additional blower unit?

Thanks in advance for any reply or advice!

Why you set the temp at 18C
Did you ever check if the temp ever ever went down to 18C
I set the temp to 18, the lowest temp. At 18, it not cool as previous. Please advise what types of service it needs to be cool again. Thanks.

----PLACEMENT FOR AIRCON COMPRESSOR WITHIN SERVICE BALCONY---

i dont have a outdoor aircon ledge so i decided to put within svc balcony.

question1:
can i just leave the compressor on the floor facing the walls?
or mount bracket for $150 and lifting the compressor up facing windows for air flow?

main concern is the heat build up in the service balcony.

question2:
i did not pay 80 dollars for the thicker insulation copper pipe.
because 3 rooms will be 240$

is it a wrong decision?

Contact Kaisoon Aircon. Look up for their contact on Google. They provided one of the best services in the open market today. Four years down, no issues. Cheers.

They will be frank with you when you decide to switch your parts to G22 or G23 or G24. Remember its always 16mm water drainage all the way from the aircon unit.

Looking for a Sys2 inverter aircon, 9000btu + 12000btu.

Is Mit Heavy Industries aircon reliable?

Insulation are either KFlex, Armaflex. They are PSB Approved.

Go for trunking if very much possible for HDB.

Make sure they use 16mm copper.

ME or MHI?

Going to replace my old National with a new System 3. Have narrowed down to ME or MHI. Please kindly advise and also recommend good installer.

Thanks!

Dear aircon experts, need your assistance in the following...

My contractor recommended the aircon system below for a 3-bedroom house.

Panasonic 12K BTU inverter single split 3 set.
  • Cu-ps12nkz x1
  • Cs-ps12nkz x3

Is this any good, as I'm not familiar with these things...
Also, what type of copper piping, insulation and bracket should I ask for (or just use default/standard kind) ??

Thanks.
