Which is more energy efficient, setting 16C and ON for 3 hours or set at 22C and on at 6 hours?

Am contemplating between Daikin Inverter and Panasonic Inverter ....which ones good and cheap eh ??Pana these days very bold on electrical saving ...this is for my bedroom unit(1HP) ..the hall one will go for 2HP normal ..as very rarely ON so doesnt make a diff inverter or not ..... 

Daikin inverter can used back conventional piping and coolant from what i heard, hence installation is cheaper and when u change aircon next time, u can change to non-inverter type

so Daikin is more economical even with inverter? What about its service maintenance?

Planning to get air-cond this week because of current hot weather. This model good or not?

Panasonic Deluxe CU-C9KKH = RM1320
or Panasonic Inverter Deluxe CU-S10KKH = RM1420
(Price include normal installation)

The price of the inverter almost the same as non-inverter so I'm in big dilema now. Which one should I get? Inverter really can save electricity? What about the maintenace cost?

I am looking forward to install an air conditioning unit. the more shop i asked, the more confused i get. Currently i have these 3 brands in mind :

1) Panasonic
2) Mitsubishi
3) Daikin

Shop A says : Panasonic nowadays made in China, not really reliable anymore. And Panasonic inverter is not as useful as advertised, the energy saving is minimal compare to other brand's inverter. Daikin is the best, he can guarantee minimum 30% reduction on bill with daikin. Furthermore Daikin inverter model uses cheap R22 gas. Other alll use R410 which is expensive

Shop B : Mitsubishi is the best, but mitsubishi parts and servicing is very expensive. The best price to performance ratio is Panasonic.

Just a question, how long can aircond piping be? Forthe  living room I don't like the outdoor compressor to be visible on the car porch so i thought i put it at the backyard instead. However i think the distance quite far away, so I was wondering whether thereare any limit for it.

The hot weather make us appreciate our aircon more. Last week i decided take a good
look at my room a/c panasonic 1hp. The air flow is coming from one side only and quite
weak. After poking around managed to remove the outer cover and exposed the fan, coil
and water tray. It was last full serviced 1 year ago but i was shocked at the condition inside.
the blower fan blades was covered by furry dirt. Some areas of the coil looks like a mushroom farm
but the most disgusting was the slime and jelly dripping from the cooling coil into the water tray.
Our aircon looks nice and clean outside but inside it is a germ factory and we breath the air every night.
Anyway i bought some non toxic aircon cleaning spray from hardware shop and clean the aircon myself
First time so a bit messy but results quite good. Cold and strong air after service. cost me RM30.00
only . Got 2 more units to clean another day.
Manufacturers recommend service every 3 mths but i feel 6mth minor service and every year
full chemical service is minimum for good health. (also buy a separate air purifier for added protection)

I always use dettol or any antibacterial cleaner to spray at the condenser to clean it. Doing this every month when clean the filter.

And tilt the aircon more to the drain pipe. So the condense water don't remain at the drainer and dry fast.

Hi all,

Could anyone advise me when I should have my aircons serviced? We're living here for a year now and are using the aircon on a daily basis (at night) at 26 degrees. Lately we've been noticing that it's get hotter and hotter at nights, so we put it on 25 degrees. After a month orso this too is starting to get too warm. I figured we might need to service it.

What does servicing mean exactly? Only regassing? What is a regular/normal price for that? Who should I contact for that. We are renting, so is it something I should perhaps tell our landlord (so he can have it done?).

I asked my friends from china. They said Gree Air Conditioner is the Top Brand among all the air conditioner in China. Anyone installed Gree Air Conditioner at home?
Why not you consider Gree ?
Beside price, what make you choose Midea Air Conditioner?

How about GREE ? Are they using Midea's compressor too?

Yup, that I agree.

My old house using York, after 2 years so noisy.

My brother room using Panasonic, but is quiet.

I was wondering how is Midea after sales support. Was worry of this hence did not buy Midea.

Opps...sorry...i forgot the Brand name. It is called Gree, cozy series, 2.0 HP, no inverter, plus installation RM1688, 2+6 yrs warranty. 2 years for in door unit and 6 years for compressor.
