They don't care one, they only care to make profit.

you ask the correct answer in b4 pass 6 yrs ago i am doing the way...

non inverter for 1hp i just dismantle on Rm100 to aircon man, even 2hp non inverter less than 2 yrs for Rm250 only..

cause i dont have contribute too much paid for TNB

you guys talks so easy, if ask you do the same.. i don't think they will following..

In malacca hotels more into inverter now

Only very small hotels with very small finite number of rooms (no more than than 10) may use inverter but for the cost per unit. In SG most of what I've seen goes towards VRV (variable refrigerant volume) kind of tech. Larger places would use air handler units (AHU) and probably water chilled units. The regular maintenance of air filters and cleaning of indoor unit will eventually hike up operating costs.

if you have 10 non inverter aircons dismantle for rm 100 each good condition. I will buy it from you liao. I bought 20 yrs old toshiba rm 300 including installation. now look for used aircons for my budget hostel rooms

at that time still heaven't kena u.

Roughly how much is the cost of repairing and is it worth to repair?
Can you recommend me a good replacement for it? I'm using the air cond for about 8-12 hours a day and the room is quite small,about 13x13

Top up gas is around Rm80 and clogging pipe water dipping have to check wow.

cause i am not too sure in someway m'sia

13x13 = 4x4m go for daikin ga 1hp inverter you wont get disappointed of the cooling and very accurate to keep you room cold down as fast.

price also cheap.

Actually what most of us call living room depending on the house layout is a misnomer. Although on the drawing/plan it specifies living and dining, the word room is not there. It's more like living spaces and dining spaces where the area actually is one large open floor space. If I were to size AC correctly, it would have to include both or have two AC. Second option means more hacking which is already a challenge for condos.

I also discovered that to size it correctly is not easily acheived. Say that I want to put a 2.5 or 3 HP AC. Some condos have casement windows with fixed middle bar (to secure closure of window) that is not wide enough to allow 2HP compressor hence only 1.5HP max. Only those with balcony spaces that have AC ledges next to it or the unit is on the first floor and it's within reach of a 16' ladder. Very frustrating.

So when in my current place, I decided to address this issue where the AC would forever run due to leakages of open space layout. I added a close-able glass door partition separating the living from the dining. With this in place, the partitioned space can be called a room. Only then can the AC run and then 'cut out' when the preset temperature is reached. Usually it's 27-26 degrees and 25 only when the sun is out and it's really humid. Ceiling fan helps disperse cool air.

Thus, the area has to be evaluated as to whether it's well defined by enclosed by walls and doors/narrow opening or it's actually one large space where there's an architectural demarcation (living or dining) in which case if there's no partitioning to be used, go for a larger AC. For condos, it's good if there's a balcony since that doesn't restrict the use of a 2.5 or 3.0HP.

You're wasting your time trying to explain to him. He basically ignored the part you said about the undersirable scenario there would be no savings between inverter and non inverter. He just keeps spouting half truths.

To summarize, very simple. Look at Papparich, Old Town, those standalone shop lot ones. In their case there would be no savings from inverter air con as the doors are wide open. Cool air will just escape to the atmosphere. The air con would be working 100%. There will be no savings as the LOAD is 100%.

In a sealed environment, such as a room with doors and windows closed, inverter may give you savings.

Likewise if you turn on the air con for only 3 hours or so, it doesn't make a significant difference since inverter and non-inverters would be working 100% to quickly bring the room temperature down.

Actually, I just felt pitiful for those who just listened blindly to his misleading advices.

You still dunno how to get save an used with inverter aircon and claims inverter didnt bring down your bills.

Bigger area do not used smaller size of hp at all, even smaller area can be used slightly bigger hp for keep the room quickly cold down as fast as possible to energy saving.

Ya agree with you.. that is why they never consider an expansive aircons at all, just possible can cold down the place only.

otherwise they might installed air curtain at every single door opening area to be keep the air wont explore too much outside.

Sorry but I know how to get savings using inverter because I understand the mechanism behind how inverter works. Unlike you who just blindly advised others "get an inverter, you are selfish and only think about yourself if you use non-inverter" bla bla bla...

Since when did I claim that inverter didn't bring down my bills? Don't assume thing.

You are just good at salesman talk. Improve your technical skill.

You are the only one from what i saw now.. who ever after change from inverter may reduce they electricity bill and cut into half... but in your case may different...

just sharing your temperature setting and fan speed with room size will do..

never do the correct set-up you wont get the correct way.

i hope can helping you

I already achieved the savings that I needed. Thanks for your offer but I am afraid to listen to your advice now. Not sure whether your advice is correct or not.

Cheers

Then worry u r set-up in wrong way right

You may find out here as a guide
From 16c you call the compressor runs like optimum and no tomorrow to drink more electricity

26c will be a bit too warm but usually not suitable for adults, but good for children they likely to kick off comforter at night time, also more healthy for them.

25c if your Aircon can achieved your required should use as 25c for common set-up, also save the green environment too..
Outdoor compressor may not runs like overloaded or full load else, just keep normal speed for whole night.

24c might be outdoor more hotter then set to adjust the balance of the room temperature too.

23c - 22c your Aircon not longer in cold condition should check gas pressure or do regular service and maintenance will solved.

20-21c maybe they really can't feel cold at all... That's personal reason, even inverter they might claim the unit not energy saving at all..

My sister bought a new condo unit. Cables for a/c were pre-installed.
Recently asked an air-con installer to go to have a look. He said the cabling is of 3-wire type, so can only install non-inverter a/c or Panasonic inverter a/c.
Also, he said we can only install 2.0hp a/c in the living room, not more, not less.

Are there such restrictions

Just quote with others shop
