This is so funny. Because these mass marketer do not sell a product, they are no good. Is that why you say LV bags, Patek Philippe watches, Krell amplifier etc no good?

Invertor only uses less electricity when there are lots of stop/start operation. In a big hall with small air cond, there will be no such operation, hence no saving.

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.

Added on September 1, 2011, 8:20 amI think York got several model of that power rating. So which are you referring to?

That is flawed logic. It's like saying LV handbags should be sold at Pasar Malam to be good brand and not when it is sold at specialty shops.

So if buying York, is J series the better ones? Looking for the 2HP or 2.5HP model.

Why don't you get the Panasoinc Delux model. Their EER is a lot higher than the York M you got. Comparing 24000btu model, it's 9.9 vs 8.97

I don't understand. When I check out the 24000btu model, Panasonic seems cheaper to run. Can you pls comment?

CS-C24NKH (CU-C24NKH) ~ 2.5HP
24000btu
EER 9.9
2430watts

YWM25
24000btu
EET 8.97
2675watts

You know how to check which have stronger air flow for the 24000btu model from both manufacturer?

Could.

May be it's time your brother get a Roomba robot.
