why is the prices double? more xpensive materials?

Thanks for the recommendation. I think I'll need to go to the shops to speak to the ppl. I have a Sharp that I'm supposing is NOT an inverter but it's capacity is 577l (net) and I don't see anything like that anymore for the same size or thereabouts. I like the Hitachi you recommended as it fits into the hole I have and that will leave me with a gap enough to put my fridge on a track. I've also shortlisted a Toshiba I think.

I think DC motors on fans save at least 60w? Aren't AC motor fans running at least 85w? And DC motors about 35w? I'm thinking of Alpha.

I'm now thinking of TVs and LEDs. My Plasma apparently runs at 385w!

Inverters wear out because of the boards. My Panasonic AC's capacitator blew out about 3 months ago and now the remote doesn't work very well and there was this leak that happened a couple of days ago. It's as if the AC just keeps having problems. What I didn't know while opening up the AC the other day was how much sweat / condensation happens when it's powered on. The drain hole is so small and the pan looks so small in comparison.

ACs that are non-inverter are normally set at a range where the compressor doesn't shut off e.g. 22 degrees and below. I'm guessing with an inverter, it's good for people who like it slightly warm but at a constant, say 25 degrees? I think 24 degrees is ideal temperature. 1 AC that we use every day right now is 2 stars (Daikin).

All the fridges are now inverter ones Haven't seen any non-inverters unless it's small ones?

I'm just wondering whether I'll see savings with all this appliances switch out. Probably not if these inverters die out after 7 years.
