Please try to compare again now.
Basically, non-inverter model has higher (50-130W) peak power consumption than other models.
That means even we run both in peak mode, users can enjoy better cooling experience and lower electricity bill.

The initial discussion was about saving electricity bill cost.
The purchasing cost was not considered.
If this has to be considered, please also factor in the gained features (fast cooling, ionizer, connectivity, etc) and experience (cooling effect).
Your formula can become (btu/watt + features + experience)/RM ratio.

The only cost concern is the part replacement for inverter models is significantly higher.
More features also mean more things can fail.
But this reliability can be subjected to brand, maintenance, installation, usage and etc.

Thanks for the input.
I got 2units of 9000btu Daikin standard this time. Will consider inverter if bedroom ac die next time.

Another separate question. Is it normal for AC not so cool when it rains? I need to lower the temperature n fan up when raining. A few of AC units even the new ones. Got to do with the humidity level? Should set AC on Dry instead?

Thanks again guys.
Cheers...!

Can we service air cond already?

My air cond motor seems to be running all the time even though I have switched it off via the controller. And there’s still something running in the air cond with air flow.

The only way to stop it is to switch off the main switch from the wall. And the moment I switch on the main switc, it starts again. There’s no light or whatsoever on the unit, even the flap hasn’t been opened until I click on the remote control, just the motor running inside.

Is this a major issue? Do I need to look into new replacement unit?

Could be PCB faulty (does not respect the OFF state); because the indoor (IDU) blower fan should only operate when it is in ON state.

Why PCBs go bad?
PCB can go wonky over time (electronic failure), or it could have been overvolted by lightining surge (if u did not cut power to it using the switch box but just off using remote).

is it still safe to continue using for now?

My 1hp York compressor making a lot noise .. is that repairable? I am thinking to replace a second hand compressor.. the ac technician offer RM350 siap pasang.. is that worth ??

What type of noise ?

Vibration or rattling ?

If is still cold, why change ? Try to solve diy if you can access it. It could be one of the loosen screw or try place a rubber padding between the compressor and the bracket holder.

Thanks for your feedback!

It's rattling out from the fan area... yes it still cooling..
Probably you are right, loose screw or something.. AC technician usually never identify the root cause and push you to change the whole unit .. i am very sien cannot get a good ac technican.. if you have any good technician in klang valley, kindly intro me ya.... thanks much!

is it still safe to continue using for now?

Safe to use. Later after pandemic situation improve then only bother to fix lah.

Guys, any feedback on sharp aircond? Looking for a cheap non-inverter unit. Most important for me is less maintenance and reliable.

Currently looking at model aha9xcd - https://my.sharp/products/air-care/10hp-r32...-aha9xcd?v=1448

When it rains, the cooling efficiency actually increases because the rainwater and the drop in outside tempetature helps to cool the ODU which make this heat transfer as efficient as possible.

On a hot day, the reverse happens, the heat transfer becomes less efficient, hence it takes a longer time to cool the room.

That the reason why the room is colder in the early morning even on a hot day.

You can test by having a digital thermometer in the room. On both occasion, you can record how long it takes to cool down the room at determine temperature.

On the side note, your AC may be under power to your room size.

Or is it mind over matter ?

hi need advice on this 2 aircond



planning to replace my old Panasonic inverter 1hp (which needs its sensor replaced), is the newer one better?
i can see that it has a WIFI connection,

New is 'always' better.

But new is more difficult to maintain...hehe
