Assuming the capacity of the compressor is 14000 btu (system 2, non inverter).

If turn on 2 aircons, it should be 7000btu x 2 right?
If turn on 1 aircon, it should be 14000btu right?

If it is true, then the desired temp should be reached faster if you turn on only 1 room.

You don't know how to measure? The electric meter is just outside... unless yours are concealed, then i have nothign to say.
from your earlier post, you mentioned measuring the time it takes for one rotation.

is that how you measure?

not unless both FCUs can handle 14k btu which is unlikely. so unlikely if only 1 aircon is operating, all the 14k btu goes to it. However that said, it means the 14k BTU compressor will go into more freq start-stops.

however if you scrutinize the specs, most compressor's total BTU is less than all the FCU's BTU combined.

So not surprising, it takes longer to reach desired temperature with all the air-con switched on versus if just one FCU.

For aircon, It would be better if you buy the set from aircon specialist... not from electronic shops (i.e. Courts, BD, Fairprice, etc...).

It is because aircon specialist shops normally have thier own installer.

I've an advice for newbie interested in buying aircon. NEVER buy samsung aircon and especially from courts. I bought a mh070fxea4b with 3 FCU from courts.

Courts & Installer issues
1) all the units have pretty bad dented cooling fins.

2) the installer is so mediocre in their job. within a month gas pipe leak..

3) the courts installer claims they don't own thermometer cannot check temperature.

Samsung official service team issues.

1) Poor quality product made in PRC (dented fins)

2) Samsung agent came.. charge the gas don't even bother to vacumm the pipe just charge the gas.

3) damage my insulation just use aircon tape to cover and claim not required to bring insulation.

so do hear me. Up to you to trust samsung installer and courts installer. Bottomline I'll never buy samsung aircon and preferbly not from courts again.
Never get aircon and electrical appliances from Ever Joint Trading also, very very bad experience, horrible. Pray hard that you installation is smooth and on time, also pray very very hard your aircon dun have problem, else you got to wait long long long lor.....

Hi! Whats wrong with everjoint? Can you share your experiences with them? I was thinking to get from them as their prices are pretty good. Can I ask also the following?
Do they charge extra to make 2 trips?
What is the thickness of the insulation and what gauge copper piping do they use? Did you upgrade the insulation thickness/cost? Unlimited piping?
Which aircon company is doing the installation?

Consider getting a system 4 and listed out the below.
I am staying in HDB 5A . so master bedroom will be abit bigger.

Usage pattern seldom maybe once/twice a week for 1-2 room but i am worry that after installation the usage will increase to very frequently

By getting the below, will the BTU be enough to cool 4 rooms or only 3 rooms will cool while the 4th room will take a while to cool due to not enuff BTU.

Should i get upgrade pipes at $230 to Armaflex 1/2 Inches. What will be the difference between 1/2 inches & 3/8 inches

Mitsubishi Electric MXY-4A28VA & 4 x MSYGE10VA

Energy Consumption Full Load/Part Load 6395 / 2132
Annual Cost Full Load/Part Load $1947 / $649

Toshiba RAS-4M26SACV & 4 x RAS-M10SKCV

Energy Consumption Full Load/Part Load 6074 / 2190
Annual Cost Full Load/Part Load $1847/ $667

Any recommends by the pros out here? Very novice to aircon purchase

Replacing inverter with inverter, i don't think can get 20%. Most likely 5-15%. Factors for existing aircon dirty, slow cooling effect, wear and tear issues. 20% too much.

SHARP SYS 3 - INVERTER

Just to put some info on the web for people interested...

Bought at Gaincity Expo sales on 03 Jul 2011.

Purchased
1x AUX3M24LV (the outdoor unit)
2x AHXPC9LV (2x 9000btu indoor unit)
1x AHXPC12LV (1x 12000btu indoor unit) ... all 4 items for $2839

Outdoor Unit Bracket ... $150
Upgrade to thicker insulation ... $180

Total paid including GST
$3169 (bao ka liao, include running of pipes, remove old unit/bracket etc)

Freebies
5 years warranty (1 + 4 covers electrical and mechanical parts, labor and transport, exclude servicing and remote control).
Philips Micro Ipod Docking station (DCM292)

Info
http://www.sharp.com.sg/web/products...=335&mode=Feat

Not sure if I got a good deal as I'm not really into air-con, picked this because it's all aluminium, got the ion thingy built-in which my mom really like, and it's got 4 ticks, full load 2.07 and partial load 0.67 if I'm not wrong.

They will be installing on 20 July.

By the way, the salesperson Mr. Roy Lim was very patient, friendly and knowledgeable, he really took his time to explain to us, clear our doubts and even demonstrated the functionalities of the air-con thoroughly, I think all salesperson should learn from him, not like the earlier guy so impatient, ask him something his face like want to fall asleep, yeah, he even open his mouth and yawn like nobody business when my mom asked him a question haha... Later ask him what about our old air-con if we buy new, he say they can un-install and remove for us but we say what if we want to keep (my mom want to give to uncle), he very straightforward say then you un-install the air-con and the bracket yourself then call us to install, wah lao eh, like that also can lol... think he really F-care liao, stand so many days sibei sian liao lol...
