System 3

Looking at Sys 3. Any recommendation for mid-price range?

Probably 9k BTU or 2.5kW for each room is more than sufficient. Room sizes range from 150sqft to 180sqft. Usage is abt max 1hr daily.

Hello Lazy999,

Was the main power switch of your aircon recently switched off and on or do you have the habit of switching off the main power when you are not using your aircon?

For Toshiba, the units will sometimes blink when the main power is switched off and on and you will need to switch on and off the individual wall mounted unit so that the blinking goes away.

Otherwise if it is not the above, you might want to approach your installer and have them come back for a check as yours is a newly installed unit and should still be under general warranty.

Best Regards,

Hi Bro Jason,

Ya, i have the habit of swtiching off the main aircon when not in used. I thought if never switch off and put it on stand by mode, electricity is being consumed but to a minimize. Please correct me if i am wrong.

So i can assumed my unit is normal then. Thank bro Jason

Hello Bro Lazy999,

I see. If that is the case then most likely this is the cause for the blinking.
Supposedly this is normal. Do monitor just in case and if you notice blinking even without turning off/on the main switch or any other abnormalities, then do approach your installer.

Yes you are correct that electricity is still being consumed (standby power) if the main switch is not turned off.

Personally I do not practice switching off the main power as I prefer the convenience of being able to turn on my aircon anytime of the day with my remote without switching on the mains . Since you have a Toshiba Inverter, the standby power shouldn't be too high. If you use your aircon frequently I would suggest leaving the main switch on.

However this is up to individual habits.

Enjoy your new aircon system


Best Regards,

Jason Tham

To aunty lucy,

I will like to ask u a few questions.

1. Do u own a Toshiba aircon?

2. I did mentioned blinking is normal for Toshiba, but i didnt mentioned no blinking is spoil.
For Toshiba, if operation light is blinking, it can be normal.

Aircon will not blink for fun. (I am not sure, got to ask the aircon if they will blink for fun... )

I am certainly not a noob, (@ least not to the few ppl here in the forum which i have provided some advice or opinion on aircon matters @ least)

Pls do not come here & stir ****.
This is a place for us to learn from each other on aircon matters.

& if u are uncomfortable with Jason using those normal book shop invoice, then pls do not engage his services.

Hi bros,

from what I understand from researching, if compressor is switched off at the main db, you need to switch it on and on standby for 5-6 hours before you can switch on the fan coil, otherwise compressor might spoil? Is that correct?

I believe the standby power is to keep a heater inside the compressor operational to prevent the refrigerant etc from becoming too viscuous to flow and damage the compressor. Noob here. Please enlighten if possible.

To troller,

No need to leave it on for a few hrs before u on the aircon.

The few hrs u mentioned is for bigger capacity units > 45k btu.
But now, they have a heating element inside to speed up the process instead...

No worries...

Hello TROLLER,

From my understanding heater is usually found in some industrial aircons or some units with very large BTU or aircons in cold climate. Personally I have not come across heater for the smaller residential models here so far.

If you refer to your aircon operating instructions manual, you might notice that they usually indicate turning off the breaker/main when the unit is not used during long periods of time and what to do to prepare the unit for use again after long periods of turning off. I would supposed that if it is necessary to put it on standby for 5-6 hours to prevent damage to the compressor, the manual should indicate. Hence best to check the manuals just in case.

Best Regards,

Jason Tham

Hi, I currently encounter some issue with my room split unit aircon.

Don't really know how to explain by words. What happen is the air coming out from the blower(think it is call fan blower? Cylinder shape one)should be cold air from left to right, across the length of the air blower. However, since last week, I encounter my room take too long to feel cold as compared to previously.

I used my hand to feel the air coming out from the blower and found that the air blowing out are sort of intermittently from the left till center of the blower, sometimes got air sometimes no air. Cold air is blowing out all the time normally from center till right side. As the blower is turning as a whole, i find it strange that this happens.

Can anyone suggest what happened? Not enough gas or dirt build up? It has been about 5 years since i last service the aircon. Also any highly recommended air con service guy to introduce and price range for gas top + cleaning? Scare kena chop by any random guy. Thanks in advance.

Hello Leongws,

Based on description chances are the coils and blower is clogged with dirt which is why the cooling efficiency is reduced. As dirt builds up at the blower and coils, air emitted becomes intermittent and sometimes the unit will start to have some sort of a "whooshing" sound as the air is blocked by the dirt during emission. Depending on the actual condition of your unit, a chemical procedure might be necessary.

As it has been 5 years since you had last serviced your unit, now is a good time to contact your contractor to have them do a check and from there they should be able to advise what is the actual fault and if a chemical procedure is really necessary. Otherwise what would be the best way to resolve this.

Best Regards,

Jason Tham
