Am I too old for this?
You are totally wrong.
Checking the spec is to know more details and does it fit the purpose or not.
Like I bought a fake Lancer last year together with my wife's Jazz. Both are driving the same mileage daily and both of us also almost the same condition, stop, go, stop in traffic jams.
End up my fake Lancer are doing 13km/l while my wife's Jazz 10km/l.
Checking the spec not important? Well, as said, I'm a cheapskate(if this can make you happy) and only willing to pay rm50-70 of TNB bill comparing to your bill of >rm100 and still boasting around that your appliance are saving energy

Because by talking on the gas, they can boast they know better than you, simple as that. This is something like a fanboy want to boast on his junk are superior than your equipment.
Regardless of what gas being used, it is just a transfer medium. How you install the air cond's outdoor unit, what is inside your room, type of bricks and paint being used and other factors come in to play.
Like now I'm using non inverter air cond, my bill still about rm50-70 but a fanboy here that keep on boasting how superior his inverter air cond is, his bill still > rm100.

Ok ok From Rm50-70 just like usage washer dryer only.

I can expected your home appliances very lesser than others household

Did you swap cars and test? It could be driving pattern.
Just like how the same air conditioner, in the same size room, can have very different power consumption based on usage pattern.

I think to summarize between R22 and R410A, very easy.. if you want cheap air con, seldom use, R22 lah. I also use R22 in my other home, I'm only there once every other month. No reason to get R410A or inverter there.

If you're moving into a new home, makes more sense for R410A as you need to lay out the copper pipes, especially true for concealed pipes, as R22 is being phased out.

Tested, still the same. And my driving behaviour are more aggresive
Anyway, back to topic, some inverter models are also using R22 gas. So, the gas difference makes the air cond behave differently does not stands.
Also, we can't do an objective AB test on the gas difference and the effect from it as no manufacturers are building the same air cond model that can use different gas.

Ha ha you won't knew R22 after usage a few years later on the gas itself would turn into darker or more sticky without runing smoothly, unlike when new.

That is why old compressor works harder can hear vibration and higher noise level as well

Yes, you are right, now my outdoor unit darn noisy when I compare it with my portable HDD
But surprisingly, a new Samseng outdoor unit's noise level are like a diesel engine that never been service for 5 years
I know you are trying to cheat and mislead people here on your bullshit, but until today I never see a gas will turn color by itself, especially in a closed system
Want to cheat, look for better lies lar, brother.

i never believe non-inverter air con will be silent than inverter...thats bull shit as well... my neighbor staying opposite me is using non inverter... the noise level is unbearable ..luckily my overpriced flat unit is not directly facing the blackies....



imagine i can listen to the compressor sound if i stay at living hall ....my flat very small unit only...less than 1400sf ,...

Basically is the fan design matters. I every year will apply some lubricant to the bearings. My 10 year old non inverter Panasonic 1.5HP air cond's noise are at 35dB only. A York air cond can sound as loud as 45-50dB while Samseng air conds I measured when I work in Qatar are at 85dB with high vibration
Regular maintenance are another factor.

Is airconds more expensive now with gst? Wanna shift to econavi inverter..

that air con not cold 1 wor. power savings 9 9 lah.

Price should be the same. The most may up by 1% since GST replaced SST and seller can claim back 3% from government.

Just selfish ppls who willing to paid for non inverter at all.

One more question,regarding d air-cond on off switch(with d red light),can we on 24/7?
Will d power comsumption very high?
As i am a bit lazy sometimes to on d switch as it is at d far end corner of my room.

On off switch if necessary for when repair or cleaning maintenace will do..

If on & off too often may cause on PCB failure in future.

Can, you can leave it on 24/7, provided you do earth leak test weekly.
As per ST(government)'s advise, it is good to power off and unplug(if possible) the appliance when not in use.
If you leave it on, it will consume some power, this you need to check the spec of the air cond.

I dun think most of d air-cond installed can be unplugged,unless u ask d installer to do it purposely for u...
I know it will consume some power for sure,but by how much? Ani rough figure? Like rm10 / month?
So from bro kimsim,i got ur meaning by jz leave it on rite?

That's why I said if possible, else just turn it off
It will consume few watts only. But the risk is, if got lightning strike, it will damage the air cond.

During calculation , how do we split the ratio between full load and partial load ? Usually full load run for how long ?
Thanks

Is depend on area space and weather.

There is no fixed at all, just simple door opening then can the see light turn on for increase load speed.

That's why called it variable speed on inverter technology
