Hi guys,
I'm currently looking for Mit Starmex sys 4 inverter for my new BTO (3 rooms same size, living room bigger one).
Any recommendations on who I should go to and rough price gauge?
Hi, greetings to all,
Great forum!! hoping that I could get some advice from our bros from here. TIA.
Currently, my 10 old daikin system 4 (R22) is beyong repair as daikin quoted abt 2k in repairing. All my pipings (tested no leak) and wirings are concealed, now wana consider to change MIt R410.
1) I came to know Mit Elec MXY-4A28VA have this call "clearing free, pipe reuse" technology, dont what it is? but sound like it could just reuse the old pipes without special flushing/treatment, would some guru advise me?
2) I am also considering Mit HI SCM80zj system4 that quoted cheaper by abt $200 as compared to above, but did not mention the "pipe reuse" technology.
3) the aircond servicing technician told me, just vacum the piping will do, which i feel very uncomfortable with the remarks.
When google for the information, some said pipes need flusing with nitogen, I confused liao. would appreciate very much if any one could share.
Why u want to using back the old piping ?Hi Jason,
Thank you so much for your professional views, your advice has enlightened me on the technical aspect.
I too, would like to change all the pipes, because the discount given by the installer for using back old piping is not significant, however, the process will be a messy once, as it involves dismantling almost all the false ceiling.
After considering, I will take the risk to use back the old piping for ME, and inform the installer to flush the pipes.
1) BTW, what is "Pump-down process" ?
2) About how much will it cost (just indicative) to flush the piping with nitrogen? and
3) Would you share your experiences of old pipes failure (in term of %) for changing R22 to R410 you have encountered?
Regards and my apology for my ignorance.

Are your old piping concealed ?
410A gas model air con need to us 22 gauge piping by agent . ( if not air con got any gas leaking agent don't give any warranty )
After 2-3 year your old piping sure can t take it . coz 10 year also not must contractor using 22 gauge piping.
Don't take the risk
Hi Jason,
wow... your respond is fast , appreciate your efforts of explaining the pump-down process. thank you!! thank you!!
Yes . is better using back the R22 Daikin 4MKD75 gas for your air con system . u also can ask the contractor to flush for u before they install the new air con . so far no any complaint in R22 Daikin 4MKD75 using back the existing piping . an u got the warranty for them tooHi Mrairc,
Yes, my is a condo, all the pipes are concealed, that is why I resist to change the old piping. If renew piping, the false ceilings will need to be cut or dismantled, and ....the reinstatement as well . Moreover, if the new installed piping not perfectly done, it will be a nightmare to reopen the ceiling....
Considering my existing piping were well done by the main building contractor, which 10 over years still service me well without problem, that make me thinking of retaining the old pipes.
You hit the right spot of my heart that is what I worry most if the old pipes will to give problem in just a few years due to the additional pressure induced by R410.
if this problem is concern, will it be better for me to use back Daikin system like 4MKD75 that uses R22 with the old piping?
TIA.
Price reasonable ,extended warranty can think about it , but service contract not necessary. Now all news house already got installed 15 amp for air con power point . The best is they giving a three year workmanship warranty .
Hi All Gurus,
I am planning to install new air con in my 4-room and was looking at this particular model Mistsubishi System 3 inverter MX3A28VA/MSYGE10VA at $3,009 including standard HDB installation which is selling at Gain City.
As this is my first time getting a new air con, please advise if the pricing is reasonable as i am going for the installment payment term.
I understand it is necessary to install the steel bracket and 15 amp power point with PUB testing. Is it necessary to upgrade the 1/2 inch insulation and guage copper pipe.
Thank you all in advance.

just sharing my small experience scouting for air-con.
Went to this shop called best tech at toa payoh. Asked the salesman price for sys 4 for Toshiba. He told me $3899. Ask him about ME. He said same price. Ask him about daikin. He said same price. How can they all have same price Not sure whether he is trolling me. Ask him for G22 copper pipe he say cannot. Now use G23??
Went to courts Toa Payoh. They don't carry Toshiba and daikin. Cost $4299 for ME and only one year warranty.
