Yeah...Malaysia boles mah..they always have their own standard...today just talked to the air con contractor from my developer..he said the copper size can definately use r410a..bit doubt on that...cause what I heard my copper pipping got joint...afraid later leaking gas because of pressure problem at the joint part..planning to ask the air con contractor to redo my copper piping....don't want headache in the future...maybe use back current air con r22 to save bit budget...oh btw..u say last time first how many meter copper pipping cost how much dy? Additional how much dy? Don't wanna get con by this developer contractor worker...they do free lance one...and inverter need 4 wire or 5 wire together with pipping ah?
Anyway just to share out....I called daikin Malaysia today...a tech supervisor from Johor that attending a training in hq was answering me in this tech question...when I asked bout r22 phase out is there any replacement...he told me r407 can use to replace the r22 gas...can use back the old same aircon, same piping and same compressor unit....but once I called up pj one of the dealer of daikin...he said not yet have official announcement on that....
Ya from R22 don't have any inverter models, if wanna save the units cost for headache in future of TNB bills.Anyway just to share out....I called daikin Malaysia today...a tech supervisor from Johor that attending a training in hq was answering me in this tech question...when I asked bout r22 phase out is there any replacement...he told me r407 can use to replace the r22 gas...can use back the old same aircon, same piping and same compressor unit....but once I called up pj one of the dealer of daikin...he said not yet have official announcement on that....
Take the R410a at least you can use for inverter for saving energy.
Actually like Pana, Daikin and Mitsubishi electric already selling R410a for non inverter and inverter models as a standard models recent.
From ME & Pana most likely phase out the R22 in markets so far.
Just left some budget brands & models still runing on R22 gas only.
From standard packaged for installation fee: Rm250 per 1hp for R410a gas and comes with 3m length only, the extra copper pipe to be top up an extra.
So the joint extend copper from the walls to FCU still might to solder too.
The wires standard now all Aircons still minimum required for 3 wires, unlike Daikin needs 4 wires at least.
But concealed walls in S'pore standard should comes with 4 wires at least for 1 wire extra for backup, once the wire get burned half way, then still got extra for replace.
Even insulation should comes with on each individual foam, unlike M'sia will group it together as a whole binded, the water dripping and condensation to be after 9-15 months later.
Again water drain pipe if good should use 15mm dia at least.

The only thing i know, MHI is not a newly accomplish company, and it involve in commercial heavy duty aircond system very long time, so residential aircond is just a kacang putih to them, and MHI even exist and support Japan during WW2. More into budget user becos it cheaper than ME?? Hell no and not logic at all. I can also say ME is expensive becos its name. Singapore user prefer MEQ not necessary means MHI quality is inferior compare to ME, just becos ME also produce fridge and other electrical appliance, so its name is more familiar compare to MHI in SG. If you look at MHI brochure, the PCB inside the MHI compressor is comformal coated to prevent corrosion by humidity, ME got or not? No. Support wise, ME service center is at Tun Aminah, MHI is at Johor Jaya, i can't see any lack of support at all.
Then pay local guys to install?
