I thought its the other way around.
Inverter air conditioner uses less electricity thus save money when usage exceed 8 hours,
If less uses more electricity compared to regular non inverter air conditioner,
Got this information from my uncle who is an electrical appliances distributor.
Confirmed this fact with a few electrical brands representative when I was visiting the goverment's energy efficiency subsidy roadshow (forgot name) in Kelana Jaya's Giant.
Just because they are in that business does not mean they are not idiot.
Invertor air conditioner has to convert AC electricity to DC electricity. This conversation will incur a lost of 10%. So if you both air cond are used at FULL BLAST situation, an Inverter will use 10% more electricity. FULL BLAST commonly occurs in a big hall/huge room with too small an air cond.
In a smaller room or room with large enough air cond. When temperature in a room reaches the desired or set cool temperature, normal air cond will totally switch off the compressor (only the blower is working). And had to restart the compressor when the set temperature goes up. This stop-start operation uses a lot of electricity similar to a car uses more fuel in stop-start traffic jam situation. This is how normal air cond works.
In a similar situation of lots of stop-start, an inverter air cond's compressor DO NOT STOP COMPLETELY. It merely slows down and pick up speed again when room temperature rises. Since there is no stop-start operation, it uses less electricity. This is similar to a car that never have to totally stop or restart all over again hence reducing fuel usage.
Using car as an example, it's a fact traffic jam with stop-start uses more fuel than an non stop driving on highway. Nobody can argue with that. Likewise, nobody can argue Invertor do not save electricity.
Of course if you only use your inverter for only 1 hour when it doesn't even have time enough to cool the room or enter non-stop/non-start operation, it does not have the time to help you save money.

if im not mistaken, york was bought over by daikin sometime ago.
cheapest i've gotten so far for daikin air conds (non-inverter types) :
1hp - RM860
1.5hp - RM1260
2.0hp - RM1660
EXCLUDE installation. i didnt get a quote for installation as i hv someone else doing it for me
I think York got several model of that power rating. So which are you referring to?
