after calculate the total BTU, my master room requires slightly more than 1.5HP but less than 2.0 HP. Shall i go for 1.75HP as i know Panasonic has 1.75HP Inverter

Does R410a save more energy than R22 ?
Does Daikin Inverter air cond with R22 save as more energy as other Inverter air cond with R410a?

Hi all,

Have you all wondered why the refrigerator once bought no need to service refrigerant for many2 years, but if aircond always kena pay extra to add refrigerant...... When doing servicing.... I would imagine the concept to be the same.

Sure.... But I will be getting the non inverter type coz according to my aircon serviceman, inverter aircon a lot of problem.

5 years? Then it must be very expensive that time when you bought. I'm still looking air-cond for my new house... Still hanging around Sharp/Midea/Daikin inverter...

Re Aircon installation

Hi All, I suspect my aircon's water pipe was not install in proper way, please see attached photos here.  my contractor did it horizontally instead of vertically....somemore he connect it to the main paip... :S

I'm using 1.5hp Inverter Media. So far it's good , no prob.

avg on 8hrs/day,bill= Rm129/monthly  (besides usual 1x TV, lights, fridge etc)

is like a jelly air con. that normally cause of water dropping due to it.

Copper pipe is brazing. Not solder or weld. Dont bend it I agree. Warp the outlet with muskin tape and outdoor side put plastic bag. Get your AC installer to vacuum kao kao during installation. Just leave it there and dont cut. Poor brazing work will result in leakage. What they do in factory is that after they braze the will usually test the brazing point with a 450 to 600 psi pressure depending on pipe thickness. I doubt that your AC man can do that. Do not cut.

oic, tq.

Added on July 12, 2012, 8:36 amdear all, hv u ever considered portable aircond?

benefit is u just buy one aircond and use it everywhere....

the drawbk,i think how to dissipate heat

i m considering, hvnt buy yet

haha..sound so comical  ...drag around the house..

I tot of getting one for dining..just in case..Coz of the location of the aircon at the living, by the time dining is cold enough, living may be a liitle too cold for comfort..

Hi,i have lost my remote control from SHARP ah-a9mev, is anyone know where can i buy it?Pls help,aircon srsly useles without remote control=(

Ok guys, need input from you on my aircond calculation:

So I plan to buy:
1x 1HP Panasonic - in master bedroom (15 x 12 ftsq)
1x 2.5HP Panasonic - in living room (25 x 12 ftsq)

All are using inverter technology. Also, the height of my house is 11 ft.

So base on the following calculation:

0.76kW x 8hr x 30d = 182.4kW = 182.4 x RM0.40 (assuming it's the current rate) = RM73

inverter
Panasonic 2.5HP - living room

1.9kW x 8 x 30 = 456kW = RM182.40

Total = RM255.40
Assuming 35% saving from Panasonic's website = RM255.40 - RM90 = RM165.40
plus with my other utilities ( fridge, tvs, etc) = RM165.40 + ~RM45 = ~RM210.40

Is this calculation correct?

Thanks sifus! 

True, but I will install a wardrobe that will occupy some 2ft from the width. So will make the room become smaller, although not very significant. 
So this means the actual average monthly bill might be LOWER than what I've been calculating? Furthermore, I'm not really gonna use the aircond in whole 30days. Maybe certain day I will use <8hrs or maybe just using fan during cold weather. 

Let say if I try to make the living room more darker + cooler eg. putting some heavy windows tinting ( I won't get trouble from local authorities right? Like heavy tinting on our car windows, later kena summon by JPJ  ) + installing really thick, dark colored curtains would help a lot in making the room cooler; less load for the aircond to run no?

hi all, have some questions

my existing AC is old, pretty old in fact, but came with the condo

issue is that after servicing/cleaning and also gassing up, it runs cold for a while, then after that just blows room temp air out. is there a problem somewhere that can be fixed, without replacing the entire unit?

also, any trustworthy AC guys out there that can be recommended?

Anyone knows what to do with the old unit? In Malaysia is there a rule on ways to dispose the old aircon? Or normally you guys trade in?

Thanks!

I'm buying some AC units for the new house, copper piping has been provided by the developer so I'm looking for a recommended AC installer only.

Will most likely buy 6 or 7 units of 1.5hp inverter AC myself. I personally prefer Hitachi but it looks like there are a lot more options for Panasonic inverter AC.

I went through several pages of this thread but didn't see any contact info. Can someone recommend an AC installer in the Puchong area? Thanks.

York - Cold down very faster, but compressor getting noisy after 1 year.
