Just would like to know, are there other aircond brands out there in the market that has the same indirect cooling feature like what Panasonic has?

Also, any forummers here have experience with Mitsubishi Electric? Never really fancied the brand before but one electric shop salesperson tried to convinced me to get it. Like the easy cleaning feature though where you can open up the vanes and all that to wipe the inside

Hey guys, as I’m upgrading my master bedroom to 2hp, I have problem what to do with my old 1.5hp daikin inverter. I’m thinking to move it to my other room but those rooms are smaller 10ft*10ft. I think this room just require 1hp. So if I oversized to use 1.5hp inverter, will it still save electricity?

compressor weak? you better get a different aircon guy.

Hi, recently eyeing for a house Rm295k, double storey terrace, but my friend brought 1 contractor along to see the house. The contractor walked upstairs and tell my friend, there is no aircon thinggy being installed, might cost us alot when the house is VP, then we need to pay some money to get the aircon installed. I wonder what does he means? He got no knowledge in this too, i assume, do you think maybe the DB got no slot for aircon? would it be possible?

Because this is a low cost property, i wonder is it normal it might cost alot for a new house to install aircon? Or any professional might forseen any issue for a low cost property to install aircon, kindly advise. Appreciate it.

From your opinion, is it normally DB would have the slot for aircon, just there is no point from DB to upstairs right? Normally how much do the cost to install 3 aircons upstairs in this case?

my company want short cost for repair aircond. since my boss see my background is mechanical, so he told me to fix the aircond myself -.-

I kena before on my old Inverter (CS/CU-S10MKH) outdoor unit, rusting around the valves area. Visible under the unit as well as when the valve cover is removed. Indoor wise, like what Slimey said, had some dust collection on the cooling coil on the indoor unit. What I do nowadays on my newer units, I use a paint brush to clean the cooling coils.

hi guys. what aircond brand is good? am bout to buy panasonic 1.5hp premium inverter model css13tkh with R410a gas.. is that good? or nay suggestion? i saw r32 quite good..

Cute baby aircond at the hotel I staying. Not enough cooling during afternoon, night still OK.

I guess it’s 0.75hp. MHI

My Panasonic AC decided to stop working during the middle of the night with the timer led blinking

The error code is H99

My 12-year old Daikin Inverter aircon has stopped working, and I am considering on buying a new set instead of repairing.

Appreciate some advice :-

a) My current aircon uses R22 refrigerant. However, when I first installed it, I put in a thicker copper piping to future-proof so that if I were to replace my aircon a few years down the road with another that uses R410a (which operates at higher pressure), I can reuse the piping (the piping is embedded in the walls, so difficult to hack and change).

b) However, my aircon unit lasted more than 10 years and even R410a is obsolete now. The current aircons mainly use the R32 refrigerant. Does anyone have any experience with reusing the piping when switching from a R22 split aircon unit to a R32 unit?

c) From what I read, the oil used in R22 vs R32 is very different, thus, unless the piping is flushed very well, it may cause problems. Also, the piping needs to be able to handle the higher pressure of R32 as compared to R22.

d) Would it lower risk to switch to a R410a aircon instead if I want to reuse my existing copper piping?

Thanks.

I guess 10 to 15 years is expected lifespan for most aircons. Just curious, why are you considering to change to Mitsubishi instead of sticking to Panasonic?

Yah man.. worst time for aircon to kong. I am the same predicament.. of all the aircons, the one in my bedroom has to fail. Now I can't even get a technician to help me install a new one until MCO is over.

I think R410A units are equally efficient and it's technically 50% R32 and also R410A units comes with bigger ODUs, hence negates the possibility of having lower efficiency. As per a research document from Diakin, R32s produce more acids compared to R410A during operation which corrodes expansion valves hence they had to tweak POE oil with acid catcher additives to reduce the corrosion levels. R32s are only 4% more efficient than R410A as per that document. I have seen many Mitsubishi units that are very reliable with R410A and also does not cut off if the outdoor temperatures exceeds 43 degrees and I heard that R32 units cut off early due to excessive heat produced by the R32, but this depends on the type of compressor and design. For example reciprocating compressors can work well beyond 43 compared to Rotary. So it's basically depends on the technologies incorporated into the compressors, I am not saying R32 machines does not work at a high outside temperature, but I am comparing older R32 units Vs older R410A here. There are some R32 Models made by ME/MHI that are rated to work even at 50 degrees C today. But comparatively R410A units are a little expensive and rated BTU/HR on R410A units are comparatively higher. Current R410A ME/MHI Non-Inverter units are mostly R410A. And most of the bigger VRF/VRV are also R410A. And general consensus is that, it is also safer for the technician during filling of R410A gas compared to R32. (Subject to Correction). Will also upload the research document from Diakin when I find it.

Thanks will do. Pana spare parts is closed so i cant do it myself 

How about the noise level of the outdoor unit between Mitsubishi Electric (I assume yours is ME and not MHI?) and Panasonic?

I’m considering the ME JR series or the new Panasonic 2020 R32 CS-PN9WKH

thanks for sharing bro.. thanks to you i managed to contact them and get some spare parts to hopefully repair my Daikin on my own.

did you manage to self repair your aircon?

So my wife kept making noise cause this unit was leaking and baby can’t sleep 😅 #yolo



Jelly... jammed my entire drain pan. That purple stain, I’m suspecting the guy who serviced might have used iron remover 😓


I think it was about 6 months since the last service.


I got it on back without error code phew.

JP series is the Mr.Slim right, which the R32 inverter is phased out unfortunately. So I went with Panasonic for my wall mounts for my new home since I got the hang of it on how to service them now.
