I just bought an LG unit yesterday before I read this thread. Oh man, I didn't know an LG model is problematic. It was quite cheap for a 1.5HP model, so I took it. Hopefully not much problems. *sigh*

Hi
I plan to install air-conditioners for the 2 backrooms (upstairs) of a double storey house which are the size of approx 10ftx 10ft and 8ftx7ft. Both room do not have airconditioner points. These are the aircon specifications that I obtained from the Senheng website:

PSN-CSC9KKH 1.0HP
Advanced + Plus
e-ion
Air purifying system
super quiet
blue fin condenser
RM 1199

PSN-CSS10KKH 1.0 HP
Inverter Technology
Advanced + Plus e-ion
Air purifyer system
super quiet
RM 1329

YORK 1.0 HP
Build in starter
super fast cooling
high energy saving

SHARP- AHA9KVC 1.0 HP
turbo cool function
LED front panel display
Roo temperature display
24 hr on/off timer
blow dry function
dry the evaporation for 10mins after the aircod is switched off.
RM 999

Hitachi - RASS10CX 1.0 HP
nano titanium filter
stainless filter
UV fresh
RM 1599


Hitachi- RASE 10CY 1.0 HP
cooling capacity
9200 BTU/h
sleep mode
reliable fuzzy logic control
DC power system
auto restart
green fin condenser
high energy efficiency



1. May I ask your opinion whether the air conditioners above are suitable and which is/are most suitable in terms of durability and efficiency? Any other recommendations? Any knowledge of whether any other shops are giving a better price? My house is in Puchong.
2. Normally, no transportation is provided and the shop will recommend the installer so that the installer will transport the air conditioner to the house. May I ask what are the necessary technical procedures on the installation that I need to check and confirm with the installer before I appoint the installer?
3. Please advise on the proper wiring and electricity connection as there is no ready air conditioner point ( I understand that there would be serious complications if the wiring is not done properly). Thank you.

1. Your rooms are not big, so 1HP is good enough. if you intend to turn on the air con for more than 8 hours every day, and not setting temperature below 25 degree, then you should go for inverter air cond, it can save a lot in the long run. currently the hitachi inverter air cond is the most efficient one, but also is the most costly. I'm using the Hitachi air cond to cool down my master room (250 square feet), set the temperature at 26 and turn on 8-9 hours every day, it used around 2.5KWh per day, which is around 80 cents only.

2. Get the air cond from the air cond shop, they will do everything for you, and the price is cheaper than sengheng. normal installation costs RM150 to RM250, depending on inverter type or normal type.

3. The air cond shop standard installation including hacking your wall, install air cond pipes, but do a little bit conceal, if you want to have nice conceal and paint, you will need to pay extra. inverter air cond pipe is different than normal air cond, it's thicker and bigger, and also you need to check whether your existing wires can be used for high current appliance, you may need to lay another wire from the DB box for aircond.

My personal opinion is inverter or not doesn't really matter if your aircond is only 1HP. Doesn't make that much different. With aircond in your house the electric cost will be average at 70 a month. Is really not that much.

To use inverter or not you must fulfill these three conditions or else the savings cannot cover the extra cost of an inverter aircond.

1)Use more than 8 hours a day.
2)Temperature set to 25c or higher.
3)Room sized type.

it will tremendously shorten the cooling period in the room, which in turn saves power and $

I really think is a bit ridiculous to keep aircond temp at 25. Why want to have aircond then.

Actually 25C is nice, not too cool, not too hot.

You don't want to set at 20-22, then need to wear jacket in the office or room.

I've got my 1.5 HP aircond powering 220sqft room with an opening and I set it at 25-26. After 1-2 hours I would already feel cold.

My aircond guy advise me to set to the lowest temp to quickly cool the room and then set to the desired temp. He says less wear and tear. Dunno whether true or not? tongue.gif

personally i use dry-mode with 29-28Ā° degree and fan. if you use a ceiling fan you feel cooler than it actually is and dry air has the same effect. i find that very comfy, no need to wear warm stuff and furthermore you wont get a heat-shock when you leave the house. i can recommend that smile.gif

theoutdoorzone,
this makes no sense. convential aircon is either off or full load. it will work until desired temp has been reached and then manage off/on by itself. so you gain nothing with your setup. if you have inverter, the inverter will work until temp has been reached at computer decided load and then manage temp. i dont see how setting temp to max and then stopping when desired temp has been reached makes a difference.

You set at 18 or 25, make no difference on the initial stage.
The air-cond will be running at 100% at start.
The temperature set won't affect the motor running for conventional type one. Either they are on of off only.
The temp set is for the motor or compressor to stop working.
