I contacted one supplier, and they said the R32 gas models are latest and much more saving. The gas is also cheaper than R410A.

But when I contacted my usual technician, he claims not many use R32 hence its much more expensive.

Also the same piping (0.6mm) is applicable to R32A rite?

Hi guys,

Wanted to ask, my new condo, it already has AC point dedicated plug, there is a place dedicated for compressor just outside where i should install my AC but it didnt have any hole for copper wire, should be ask a third party to come and drill a hole before i ask a aircond guy come for installation? or the aircond guy should know what to do?

there are 2 things, pipe size & thickness. 1 is fixed the other isn't.

the pipe size is decided by manufacturer even though you can say 1hp is 1 size, 1.5hp-2hp another size. the size cannot be changed.

pipe thickness is not standard. minimum is 0.6mm, but you can go 0.7 0.8 or 0.9 or even thicker as long contractors can bend them.

you can't use 1hp pipe on 2hp aircon, but you can use 0.6mm or 1mm thick pipe for 1hp pipe size.

if the pipe run involves lots of conceal and long run i would suggest get at least 0.7mm thick. but good luck finding contractors willing to quote it cheap.

when doing the conceil piping for aircond, normally we complete install with the aircond unit only start painting or the other way ?

Check if existing wire and pipe can support or not. We don't know how old ur ac.

If only 3 wires, inverter needs 4. So you can sacrifice the earth cable though not recommended.

thanks, i guess the airconds are installed like 5-6 years ago, ill get someone to check out .

Is it really true that inverter effect only good if you're using it for more than 8 hours?

plan to install air cond for my new condo.. 3 rooms..

2 room is about 100 sqft while master bedroom is about 150+.. i wish to know inverter 1hp for all these 3 rooms is sufficient? 9000btu.

no direct sunlight enter to rooms. got blackout curtains.

planning to look for sharp/panasonic/york? which one is recommend?

Quoted RM 250 to service 1.5hp daikin non inverter ecoking. Include dismantling of indoor n outdoor unit with gas topup. Standard pricing?

Hope some one can share or help me with my inverter aircon.

Model: CS/CU-S10NKH

Lately the unit not cold and hence I try to troubleshoot. So far notice compressor cut off and in every +/- 3-5min.

I check error code cannot find any fault. Only showing H00 which means no abnormality.

If some have similar experience with Panasonic inverter like this please would appreciate your advice.

Lastly, have anybody ever fix an inverter aircon before or who to call?

if my living hall and connected to dining and kitchen (open area).. about 400~500 sqft..

is 1.5hp (12000btu) or 2hp (18000btu) is better? i no need super cold environment.. around 26~28 will do.. whenever friends & family coming over / super hot weather only open.. looking for inverter as well

Quick question :

My living hall air cond is 2.5HP. Recently after switching on, there's a shrimp kind of smell coming out. After few minutes the smell will gone.

Its a 3 months old air cond.

Thanks slimey. I actually call up PM and they provided me 2 dealer number. One is Chiam Seng and another Star Air-cond. The first one Chiam seng was nasty and quoted me a higher price then what PM stipulated for visitation charges.

Star-Aircond was great and the guy actually thought my unit is ok and no issue and offer me tips and advice to test it out further. He too suspected it was either intake/piping sensing wrong in the indoor side. Therefore with your input, I will probably ask my air-con service guy do a thorough cleaning and see what happen there after. Suspect either dirty or sensor faulty which is unlikely.

Thanks again

Inverter is very difficult to troubleshoot. Actually one of my friend suggested I check the running current with a clamp meter but I don't have one. Reason was suspect gas leaking but then usually after running long time error code will appear because it can detect unstable current. I have eliminated many possibilities already just hope it's coil dirty n needs a good clean. By the way I left the Aircon running for more than 8 hrs also cannot observe timer led blinking. So no error.

Therefore will just have to wait for my regular Aircon guy to come next week as he's busy.

Just to share to other forummer, I bought a new unit Panasonic PS9TKH-1 online around rm1.1k unit price only. This one is for my another room which was without Aircon.

I meant airconds using R22 gas.

can I ask if the "fan" mode will result in lower electricity bills ?

My parents installed both aircond and fan .. but I remembered that aircond also have "fan" mode ..

Is there any differences in these two and how it may impact the bills.

Thanks

I dont get it. Does this mean aircond fan mode = normal ceiling fan ?

Just want to share, if anyone planning to install Aircon in new houses better install piping with R32 Gas. R410 r being phase out soon. Many country already have law banning R410...etc  and allow R32 only. Thailand and Singapore already implemented. Hence old piping r not compatible.

Recently surveying for AC for new house. Cheapest for Midea 1HP around RM6xx
For inverter AC is it true that if only we use more than 8hrs only can reduce electricity bill?

That's what is use to measure how fast an inverter's difference in acquisition cost is recouped vs a non inverter. Actually already saved when using as it's consumption is halved or 60% less so long as it's spec correctly. Typically, priority is bedroom. Living hall where time is mostly spent in the home can be expensive to justify even when size correctly as the cooling load is higher...the room typically consists of living and dining area with leakages to upstairs and the kitchen for double storey home.
