Harvey Norman selling rm1599 Mitsubishi inverter 1HP incl installation, is this ok?
And I found in forum, member selling Daikin for inverter 1HP but using R22 at RM 1400 also incl installation.
Is Daikin inverter using R401 better?
And is the above price ok?

Now having a bit of trouble, after I installed awning in my backyard. I realized there is nowhere for technicians to carry down the outdoor unit for servicing in the future. Unless they go all the way to the backyard path. Is it possible to do a general cleaning and service without taking the unit down?

A disappointing and frustrated day.

Today the contractor come my house to install my ME aircond, suppose i should be very happy on that, however is a nightmare for me.

My house aircond copper was concealed one, is a 0.6mm thickness pipe that suitable for RA410 gas. However due to not long enuf, they have to extend the copper pipe by welding on the existing pipe.

One thing they really surprise me was how they test the concealed pipe whether block or not is by blow the tube using their mouth ohmy.gif I really not confident for the method they used, i suppose they are better way to test it. So they continue to weld the pipe and install in door and out door unit. After they welded and bend the pipe, they not even test it again. So, i have nothing to say but 'trust' them.

Upon finished installation, turn ON the aircond, i felt very weird, the coldness is not what i expected, is just slightly colder than ambient despite they set 16'C on 1st run, so they told me run it for 1 hour only turn OFF. They check the aircond (both in door and out door) is running then they just finished the job and go back. After they back, roughly 15 minutes, i still not feel the coldness that suppose to be. I sense something wrong there, so i check the outdoor unit, i saw the fan turn OFF itself after 2-3 minutes run. When the fan is running, i check the air blow out is not hot at all, is just at ambient temp, so i suspect the compressor is not working at all.

I called back that contractor immediately, they promised settle for me by today. After 2 hours they came back and check for me. They said the copper pipe is OK (I dun know how they check without dismantle anything), then wiring OK. They check the compressor gas pressure and everything, can't find the root cause. Then they called to their boss, their boss just order them 'remotely'. That time adi 7:30pm, i adi cooked my meal so i just have dinner with my wife in the dinning room, after i go out to see again. WTF, they open up my outdoor unit and i saw they spray water into the unit. I ask them what problem, they said the compressor motor is too hot so it cut off itself, the gas inside is low, and due to compressor cut off, they can't pump in the gas, so they spray water to cool down, hopefully can pump in the gas when the compressor start running. I really speechless at that moment. They are just electrician, not ME service man, and they are not open the unit with proper procedure, out of 4 screw on the grill panel, they just open 2 of them and pry off the casing at one end to check, it made a big dent on the casing and grill, really heart breaking.

The outcome is they have no idea how to fix it, and said it need to wait for ME to check, if is not ME fault, they will only check the piping again.

I'm really angry with them now, no matter the unit got problem or not, i won't accept that outdoor unit anymore, instead i will ask for a replacement for that. vmad.gif Now the aircond is installed but i can't use, how frustrated for that.

Anyway, the good news is, the aircond total price is 1.9k, and i only paid RM100 for deposit only. If they really don't want to replace a new unit for me, I WILL NOT PAY THE REST TO THEM. shakehead.gif

Using mouth to blow are the normal work they do. Because they have the sensor(if blocked, it can't blow through).
But after extending the pipe with welding but never blow again are wrong.

Yup, you are right on this, blow job are not a must laugh.gif
But usually some will do such blow job as to confirm no rework if have problems.
That's why I don't really like conceal piping as far as possible.

You won't know until you get cheated.
That's why if you are renovating your house, always prepare the hole for piping/wiring first.
Then install 1 air cond to test market, if ok then only install others.
But since you want people to reveal the name, in Seremban, always avoid buying appliance from Thye Hin Sermban and installer Kah Air cond.

Too sad the majority technician quality in Malaysia really suck, really really suck. Technician in other country need at least diploma for that, but here, those with low education/with every subjects gred F can be declared as 'electrician'. Sorry if anyone here got offended.

The boss that i speak through phone is nice manner, everything OK. But their workers are just pure teenage bastard.

Put the outdoor unit at floor and sit on top of that without my permission, even when i'm around they saw nothing.
During installation, only 2 out of 4 is work for that, but i can see they have no experience at all. That just half play half work, not serious at all.

From my point of view, those guys are just a teenage that can't study well and been kicked out of further education kind of ppl. No knowledge, but come to install stuff that need high technical knowledge, when problem happen, they only know dismantle this and that to rework/recheck. Sei sohigh, i don think those guys will have any bright future.

From my point of view, those guys are just a teenage that can't study well and been kicked out of further education kind of ppl. No knowledge, but come to install stuff that need high technical knowledge, when problem happen, they only know dismantle this and that to rework/recheck. Sei sohigh, i don think those guys will have any bright future.

I previously have bought my TV and washer from the same shop, that's why i bought the aircond from them this time.

But obviously the contractor for aircond is different from last time (i dun think TV and washer need contractor/electrician for that), and this one is pure bastard.

Yesterday that guy told me compressor got run, but cut off due to too hot, and the gas level inside is low.

For the ppl that got some sense on aircond system will know this either due to compressor run out of gas (due to piping leakage) or the piping is bend and dented so the pressure is too high due to restricted flow. Unless i really fucking unlucky to get a lemon unit which i believe the chance is low. That's why i almost 100% confirm something is wrong in during installation, and the most suspicious one is the piping.

I asked him piping ok or not, he said: I check adi no leak no bend...WTF, how do you know there is no leak without leak test..i really speechless.

I buy things based on price, who the hell they sub the job we won't know unless we tried.

But again, I STILL HAVE RM1.8K YET TO PAY, see who patient enough lo. I willing to pay 100 deposit for know how bad was that.

Last time I also got cheated on this(from Tyhe Hin), the price of the 1.5HP air cond I bought was rm150 cheaper than others and I paid rm500 deposit for 4 air conds.
On the day I want to make full payment, they only tell me that installation are not included and it is rm180 for 1.5HP which is rm50 more expensive after installation cost than other shops doh.gif
Not to mention the installer damaged the air cond's steel pipe. Now each time I service the air cond, the installer need to weld it back cry.gif

Get another AC installer do a pressure leak test. Normally use nitrogen and then seal up both ends without AC. Take reading and another 2 weeks later to determine if there's a leak. Are you in Klang Valley?

Update for my ME aircond.

Just now ME service man checked my aircond. The conclusion they made was during copper pipe welding, the solder was went inside the pipe, eventually clogged the compressor and valve. shocking.gif They release all the gas inside and refill it, and said the gas is 'choking' inside. They said will order compressor motor and valve inside to replace, and the indoor unit cooling coil need to flush as well. They also asked me to reinstall the new copper pipe without welding. So i went to the shop that I purchased.

The boss is very kind (Maybe my face is very angry), he kept apologize to me for introduce such contractor, he said he had a meeting with the contractor boss yesterday, and they adi dismissed those guys who install my aircond that day. hmm.gif unsure.gif He also promised the contractor boss will come himself to install for me. Then i told him the checking result by ME, and i said i can't accept repair, he promised to change a whole new set (both indoor and outdoor) for me. So let's see what happen next. Luckily i din pay them full amount that day, else i'm not sure whether they still willing to bother me or not.

Good to know. Something new. This means the solder clogged compressor and valve. The ideal method of piping is compression joints like those use in Thailand.

Bedroom or non bedroom? Bedroom try Sharp plasma cluster inverter. The fourth generation inverter much improved. Using first gen in old DSH for kids room and blow air ceiling wards. Cool cocoon at 28° with 1-2 speed fan produces windchill like 26-27° yet at comfortable humidity.

What's the price of the pana inverter for the model you installed?

Bro, if the AC refrigerant flow is impaired this will happen. Same if there's a leak or there's not enough charge. I can't explain it but it happen also if the windows or door is not closed and the AC is near it. Installers are hit and miss. If you're in Klang Valley I can recommend one.

MHI can consider. Very flexible air flow pattern. See here. I use Sharp 2.5HP but previous generation AHXP24MV due to the ability to deflect air flow to the ceiling, self cleaning and plasmacluster. New generation has long air throw.

To be compare indoor aluminum coil design for more thicken the only ME and would be easily get bend and dent at all.

Pana & hitachi just so so.. Cause very weak can easily bend or dent after wash on coil fin, so the dirty dust would be remain until forever, once remain and reduce the airflow too.

York/Daikin still quite ok than others expansive Japan brands.

LG or samsung never used b4, so can't comments

This is called coil is taken from ME

Just double check the Aircon when installer they used hammer & nail the wall plate or used drill and screw to tie the wall plate?

Once the wall plate has been something dent then after temp had changed, would be created the cracking noise when compressor stop after gas kick in.

Installation to be the most important than the Aircon smile.gif

Why one of my Panasonic inverter Aircon, the remote like not sensitive. Strange thing is this unit is the closest and lowest than the rest yet it cannot detect the remote. Have to really point at the Aircon baru can.

It also makes a noise when the louvers are swinging on their own. Also after it is completely off, it can make a noise like opening or closing some valve.

I told you already, Pana never solve the louvre swing motor over a 10 yrs b4.

Just put some grease on swing motor then solve.

Remote control like KDK or Pana ceiling fan must be point to the sensor then baru detected

Just double check the Aircon when installer they used hammer & nail the wall plate or used drill and screw to tie the wall plate?

Once the wall plate has been something dent then after temp had changed, would be created the cracking noise when compressor stop after gas kick in.

Installation to be the most important than the Aircon smile.gif

Hello, I intend to buy few units of ME air con as it seems that it gets a lot of good feedback here. I wondering how is their after sell service ? Is the spare part more expensive than others ?

How is the noise and coldness of ME inverter and non-inverter

I got this pana non-inverter 1hp aircon in my room, 8 years already

last year got repair once for the compressor, replaced the capacitor or transformer thingy, as the technician claim the compressor wasn't working
refilled the gas as well.

then last night again the same thing, not cold at all, at it's the the hottest night of the year! doh.gif

I'm guessing must be the compressor again doh.gif
now thinking should I fork out few hundred just to repair & service it
or should I just throw this 8 years old unit away and go grab a new inverter type? hmm.gif

do the aircon men accept the used units as trade in? hmm.gif

Panasonic inverter Econavi if you're concerned about power consumption but not cold.

Daikin GA if you want maximum cold, plenty service, cheap spare parts.

ME I dunno. It's expensive and spare parts I have no clue.

I would choose Daikin GA.

Usually for non inverter, the capacitor will be the first to fail especially if you set the temperature too near to ambient temperature.
And when you refill your gas, did you do the major service on the indoor unit or not? If you never do, then sure it will give you the same problem.
The temperature sensor are attached to the cooling coil in the indoor unit, so if it is very dirty, the cooling coil will be cool down very fast and shut the outdoor unit fast. To confirm on this, just check if the outdoor unit workong or not.

Need help, can someone please recommend me a 2HP air conditioning unit? For living room. 30x18ft space. Daikin seems cheaper but will it eat up A WHOLE LOT MORE electricity compared to my old non inverter Panasonic 1Hp (used for small room)? Would appreciate shop recommendation too, location cheras kajang

Hello guys,my panasonic 1.0hp non inverter air cond working weirdly recently. The motor seemed to be automatic switch off and on every 5 minutes interval despite I adjusted the air conditioner to 16 degree Celsius. When I open the cover of the air cond, I saw a lot of water droplet on the fins. I think this causes air cond seemed to be not blowing any air out of it.. So I try to clean it out and the air cond started to blowing out cold air again but the motor still keep switch off itself making the whole room so hot.. I wonder is it worth to repair? The air cond is about two years+.

Ya quite big of the area.

You might consider for 2hp at least, inverter can allow you turn on more often.. Rather than non inverter for 3 hours only.

Sometimes, it is not worthwhile to fix old problematic appliances.

Labour cost may be expensive, as well as you don't have warranty that after the fix, it will not be problematic.
Fixing a compressor or replacing compressor may cost a couple of hundred buck already, unless it is just replacing inexpensive part like capacitor etc, which just a simple fix, then different story.

aiks... yeah, I set my aircons in both my room and my kids room to around 24C - 26C only
so far my kids room aircon already changed the capacitor twice already within a year blink.gif
this would be my second time changing capacitor for my room in a year, which I hope it is.
yeah, last time when they changed the capacitor, they refill the gas and service the indoor unit as well.

So if we were to set the temp to close to ambient temp then the capacitor will be blown easily?
but if we set too low, electricity bill gonna be high, set too high; higher chance for a blown capacitor?

I wonder if changing to the inverter type would solve this? or is it the same with all aircons? hmm.gif

Because you keep the compressor on & off too often then easily to damage the capacitor

Otherwise change to inverter even set to 27C still working as well

Ten of thousand of offices, shops are using non-inverter air-cond for more than 8~10 hours out there.
So they turn on 3 hours?
or they are stupid to install non-inverter?
No
Why?

Because there won't be much saving by using inverter air-cond in those environmenet, as people go in and out frequently that resulted loss of cool air frequently, and the air-cond won't able to achieve desired temp like 23c, whereby the advantage of inverter air-cond won't be significant.

Despite pages and pages explaining how inverter works, and how the saving come from, it seems still can get a grasp of the understanding on the inverter mechanism.

Inverter /= automatic save current.
It depended on how it works, and being used.

Undersize air-cond, room that can't properly heat insulated, or loss of heat, aka cool air can't properly contained within the room, you won't see the saving from inverter.
As when inverter is full blast or running 100% time, the electricity consumption is as same as non-inverter.

Look at the label of electricity consumption of inverter compressor, the wattage needed by inverter is as same as non-inverter.

Office is never care about what Aircon are you usage since the air can keep that area as cold as possible.

Coz in office is earn money one.

Unlike home user may suffer on electric bill for monthly, nowadays everything has been increased, then still wanna worried about electric bill anymore..

Different situation from ppls of views

You still never realized from non inverter change to inverter for monthly bills do you can save how much.

A: as for inverter should draw much more power consumption than non inverter, cause from inverter is offer to variable speed & capacity of cooling.

Normal 1hp inverter can able to achieve from 8500-12000 max Btu, is depend your fan & temperature preset.

Look at the label of electricity consumption of inverter compressor, the wattage needed by inverter is as same as non-inverter.

A: inverter have part loan after the temperature reaching may runs lower or slower speed of outdoor unit, even at night time the noise also keep as low than day time.

Offices space consume even more electricity, with most corporate environment are cost saving minded nowadays, every opportunity that they can save cost, they will do

That's why I said, still can't get a grasp how inverter works.

Inverter does save you electricity when being used in desired condition, but it is not "automatically" give you the saving.

Look at the label on the compressor or spec of inverter compressor, does it stated inverter compressor consume 30% or 50% less than non-inverter?
The answer is no.

Offices space consume even more electricity, with most corporate environment are cost saving minded nowadays, every opportunity that they can save cost, they will do

That's why I said, still can't get a grasp how inverter works.

Inverter does save you electricity when being used in desired condition, but it is not "automatically" give you the saving.

Look at the label on the compressor or spec of inverter compressor, does it stated inverter compressor consume 30% or 50% less than non-inverter?
The answer is no.
*
Just remember what I said inverter have part load.
Non inverter is fixed speed there is never reduce the power consumption an even the temperature pre-set are reached..

The only works as on & off, but for non inverter would more accurate on & off very often is due to raining day and night time after 2am to next morning.

When is day time from the non inverter is never works as on & off unless is set to 28C ha ha

Compare to 1hp below
If consider part load as low as 450w per hour vs fixed speed as normal input watt as 800w they Is between the big gap.

Undersize air-cond, room that can't properly heat insulated, or loss of heat, aka cool air can't properly contained within the room, you won't see the saving from inverter.

As when inverter is full blast or running 100% time, the electricity consumption is as same as non-inverter.

A: as for inverter should draw much more power consumption than non inverter, cause from inverter is offer to variable speed & capacity of cooling.

Normal 1hp inverter can able to achieve from 8500-12000 max Btu, is depend your fan & temperature preset.

Look at the label of electricity consumption of inverter compressor, the wattage needed by inverter is as same as non-inverter.

A: inverter have part loan after the temperature reaching may runs lower or slower speed of outdoor unit, even at night time the noise also keep as low than day time.

Inverter still need to run at 100% to cool down the room when the room is not cold enough or far from the desired temperature.

Tell me, when the room temperature is 28c, while the preset temperature tell the air-cond to achieve 18c,
what the compressor will do?

Run at partial load? your room will forever not cool enough, as at partial load, the coolness delivered also becoming partial.
The compressor need to run at 100% rpm to cool down the room in this situation.
Run at 100% rpm --> electricity consumption is as same as non-inverter.

That is why an inverter is offer for R410a gas only
To help the faster & lower temperatures are maintenace on 24-25c only.

Just try install Daikin GA inverter you may feel different

Another wrong understanding.

Non-inverter shut down the compressor when the preset temperature is reached, this is where the power consumption being reduced, but this is poor compared to inverter mechanism of reduce the rpm of the compressor.

Inverter doesn't run partial load all the time, it depended on the situation.
When inverter sense big difference between the room temperature vs its pre-set desired temperature, it needs to run at 100%.

Ok ok.. Nowadays still available for non inverter model..
Wait one more day is totally phase out then you would realize the inverter more accurate and works lower power consumption at all

aiks... yeah, I set my aircons in both my room and my kids room to around 24C - 26C only
so far my kids room aircon already changed the capacitor twice already within a year  blink.gif
this would be my second time changing capacitor for my room in a year, which I hope it is.
yeah, last time when they changed the capacitor, they refill the gas and service the indoor unit as well.

So if we were to set the temp to close to ambient temp then the capacitor will be blown easily?
but if we set too low, electricity bill gonna be high, set too high; higher chance for a blown capacitor?

I wonder if changing to the inverter type would solve this? or is it the same with all aircons? hmm.gif

Capacitor is store store enough of charge to energize the outdoor unit.
By changing to inverter, indeed it will solve this issue.

1st time come in here.. thinking of changing my current aircond, Sharp plasmacluster which is no longer blowing cool air. So, my preference would be 1.5hp Daikin air conditioner.

Just need some advice and clarification, what's the difference between Wall-Mounted Series and Single-Split Inverter Series? Which one is better?

Thanks a lot.

The one doesn't realise the mechanism within youself, despite pages and pages and numerous of time other explaining.

Another wrong statement.

It is gas R-22 phase out, not non-inverter.
Non-inverter can work work in R410a gas as well, if manufacturer decided to design the non-inverter to work with the gas, air-cond just need a refrigerant to work with.

It is not inverter must use R410a, or non-inverter must use R-22, only they can work.
Refrigerant function is to "transport" the heat from the indoor to outdoor only.

Inverter and non-inverter is just about how compressor works.
Inverter use DC to control the compressor rpm, while non-inverter using AC, which cannot control the rpm.

Non-inverter is not banned, it is R-22 will be banned in the future.

Inverter does save electricity and work at lower power consumption, but it depends on what is the condition of the room.

That's why no manufacturers give accurate number how much inverter can save (they can only advertise save as much as 30% or 50% with a * behind,
because the saving variable depended on the room condition itself, which vary from one and another.

Just go back home n turn on your 2.5hp non inverter for full days at least done on at least 8 hrs.

After change to inverter 2.5hp also turn on 8 hrs like me now..

So for me is never worried about higher electricity bill at all.

But I would stay away from non inverter lah

Simple tell u from non inverter 2hp easily clock higher power consumption than 2.5hp inverter unit.

Don't ask me why

So tell me now, if you have limited budget, and you can only choose one. Which one will save you more electricity now?

1. Bigger horsepower without inverter (that can make your room achieve desired temp).
2. Small horsepower, with inverter.

Both same price.

(Sorry but bigger horsepower with inverter is not an option due to limited budget).

Now you know why inverter doesn't always save electricity like you wish.

Be coz you force the unit run in lower temperatures, when gas not enought please top up lah

In good condition Aircon of inverter you won't set lower to 24C, just gas not enough and feel warm then just keep like non inverter set to 23C at all

Different brands may different cooling, don't tell me your unit are Pana inverter, is the worst to compare even Daikin GA made in Malaysia brand

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.

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 rclxms.gif

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.

The one doesn't realise the mechanism within youself, despite pages and pages and numerous of time other explaining.

Another wrong statement.

It is gas R-22 phase out, not non-inverter.
Non-inverter can work work in R410a gas as well, if manufacturer decided to design the non-inverter to work with the gas, air-cond just need a refrigerant to work with.

It is not inverter must use R410a, or non-inverter must use R-22, only they can work.
Refrigerant function is to "transport" the heat from the indoor to outdoor only.

Inverter and non-inverter is just about how compressor works.
Inverter use DC to control the compressor rpm, while non-inverter using AC, which cannot control the rpm. 

Non-inverter is not banned, it is R-22 will be banned in the future.

Inverter does save electricity and work at lower power consumption, but it depends on what is the condition of the room.

That's why no manufacturers give accurate number how much inverter can save (they can only advertise save as much as 30% or 50% with a * behind,
because the saving variable depended on the room condition itself, which vary from one and another.
*
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.

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 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 icon_rolleyes.gif

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 hmm.gif

Would like to know how many horsepower needed for my living + dining area.

The aircon location is at dining and currently I've ordered Panasonic non-inverter 1.5hp only, which I'm worry might be not enough..

Area: 24ft x 14ft x 9ft (2 ppls at most of the time, living facing west & lake which I think during afternoon - evening generate quite lots of heat.)
Entrance -> Dining -> Living.

I'm thinking whether should I change it to 2.0hp, need sifus here to give comments.

Thanks!!

yes, certain aircond has a feedback sensor cable to the compressor and there will be 4 cables, if it is not done during installation, you might need to hack the wall and get the cables out and put in another cable

so best way is to find the feedback sensor from indoor unit only such as Panasonic or Daikin

for your living room, you can still go for 2.5hp, but the installer must know how to connect the copper hose to the smaller concealed hose

regarding the refrigerant R410A, is that special requirement on the piping (if I'm not going to use inverter aircon)?

I've asked so many times to the management office & project office of my new condo, no one can give me clear answer whether the pipe installed is able to cope with R410A aircon.

I read over the internet it seems R410A will output higher pressure to the pipe so if the piping is not strong enough that will cause leaking issue?

struggling now whether to get a R410A aircon and hopefully someone here can help me on that.

Sadly to say, most condo still come with concealed R22 piping, as far as I encountered.
So high probability yours one may be for R22.

It is not some "special piping" but thicker.

If the piping is catered for R22, then advisable to install R22 air-cond, if not remove it, or install a new piping.

Get installer to inspect the piping if cannot confirm the piping type.

You are lucky not to hire this kind of installer.
Experienced installer should able to identify it easily through visibly and measurement of the pipe.

Management office only doing admin work on building management, they generally do not know technical stuff one.
You are better off to ask the developer engineer instead of management office personnel.

No, I'm not lucky. Coz I already made full payment to the shop for the R22 model. Anyway I just called to the developer engineer office and they will revert to me tomorrow. If they confirm R410A can be used then I'll change the model.

Grade (or gauge): thickness of the copper pipe, generally a thicker copper pipe is able to withstand a higher operating pressure. The grade varies from the lowest SWG (standard working gauge) or G25 (0.51mm) to G21 (thickest). For inverter owners, the G23 (0.61mm) is usually recommended. If you have concealed piping, then G22 (0.71mm) is a better option. Another thing you should take note is the bending of the copper piping. To lower the odds of condensation or poor refrigerant flow (which will make the air-conditioner less cold), make sure that the piping is bent with a proper pipe bender (thus ensuring a pipe bent of about 90 degrees).

If the piping are new, you can always use R410A in R22 piping, the problem will not arise immediately, it will take a few years before the pipe burst and you can change new piping by then

The problem is R410A has higher pressure gas comparing with R22 thus it will make the piping crack if the wall of the pipe is less than 0.6mm.

If you cut the insulator out, you can see the thickness of the copper pipe printed on. Best is check it yourself

Can use is one matter.
While the pipe is purposely cater for R410a spec is another matter.

You don't ask the engineer can use or not.
