mine is not mbr thats why dont need such high BTU
make sure ur aircon BTU is not under power for ur room size, else it will take much longer to reach the set temperature, or even worst nvr reach....in that case, it defeats the purpose of inverter aircon, becos if ur room temperature cannot reach the set temperature, inverter cannot save u on the electricity...
actually if u see our room size (12 sqm), 9000 btu is more than enough. 12000 btu is overkill... typical MBR size is more than 20 sqm.. then 12000 btu will make sense

btw, one of the room size that I plan to put is only 6 sqm.. so 8800 btu is definitely overkill

wow..yr usage alot more than my non-inverter w/ 2 fan coil usage..
how much usage to you incur?
i'm not sure why my usage is so high.. i guess the aircon technician mess up my compressor that it doesn't have "turn on turn off" feature anymore..

mine is a 3 tick aircon.. it shouldn't consume that high unless there is some faulty issue.. i'm waiting for LG support to come to my place and fix it...

Yup its all within ur budget.. like my case, the salesman keep saying 11000 BTU is the preferred one, but i insist on my stand that i have a budget to follow..

and the most impt thing is whether u mind that to on the extra 5-10mins to cool ur whole room or not...... (BTU plays a big part here, other than budget)

i think the sales is just pushing the product... 5 - 10 mins is very negligible.. just like the water heater...

new aircon can last longer.. you can take your time to clean it every 4-6 month. If you live in heavy traffic area (more dust), you have to clean it more often.

for daily usage, recommended to wash every 2 weeks. doesnt mean new one no need wash.

i just wiped it with a damp cloth... wipe every single fin and i found out that my filter isn't dusty at all (ofcoz i inspect it with my naked eye lah)

then i wiped a little inside of the blower, and the lid (cover of the filter) and exterior....

Hi guys i got some question.
Currently i have a system2 airconditioner already installed in 2/3 of my 4rm flat rooms. If i want to install an aircon to the remaining last room, is it mandatory to removed my current system 2 aircon and install a brand new system 3? Izzit possible to just get a separate system 1 aircon to addon?

depends on yr old system how long liao.. if u tink the old system too old wan to change, than change to new system 3 which covers remaining last room.

u can add separate system 1 on tat remaining room, but hav to c whether u can install condenser outside the room or not. probably need approval from hdb. normally installer wil do for u.

hey.. i finally found out how to "consume less" for my non-inverter air con. You see, the only way the non-inverter aircon to save electricity is to turn on and off the compressor by their own logic. My system 2, the other room user didn't point the remote control to FCU, thus.. the aircon doesn't know that temperature has been reaached.. then outdoor unit is running full capacity for 8 hours.. x 2.5 That is 25 kwH.

Yesterday, it only consume around 15 kwH... That is a saving of 10 unit (40% efficiency)
