just install Mitsubishi invert, on at low(1bar) and set at 25-26, still very cold. is it ok to set at 27 for a invert? will it cause any damage in long run?

Mitsubishi guy came to repair on 7/12/09 said the gas may leaking and pump in 1kg of gas, ask us to monitor 1 month. If still have problem should call Gain City to check.

Actually the aircon still not much improve, I on 22 degree, can't feel the cool after so many hours. Eventhough in the morning my marble floor also not cool. The electricity bill still same as before I change from non-inverter to inverter.

I am really disappoited and don't know what happen to my aircon.

last month just replaced my old mitsubishi heavy industries sys 4 aircon with new mitsubishi inverter sys 4 aircon... new aircon set temp at 25 to 26 is indeed very cold already (fan speed 3 bar). was advised by the installer not to set at higher temperature and low fan speed as he noticed some insulation piping appears to have sweating sympton.

did u on individual unit to test? power point current sufficient for your system? Or any possible leaking caused by pipes instead of compressor? also check that your piping routing is meeting the recomended distance.

Recommendation for low cost system 3

hi all,

i live in a 35 yr old flat, with a single unit + condenser in master bedroom. It is about 15 yrs old from previous owner and due to old piping, gas is leaking + unit is pretty old.

any recommendations for a low cost system 3, 1 for master bedroom, 1 for spare room and 1 in living room. Only the master bedroom one will be used every night, the other 2 hardly, only if there are guests.

will probably need piping work etc and retrunking.

i've seen many posting reviews on Hong Tar and All Best in IMM, what about places like Carrefour and Giant and Courts? Has anyone gotten their systems from there?

Am considering as they offer installments... easier on the pocket.

(if u are a dealer etc, feel free to contact me also) - h#e#n#g#s#h#e#n#w#u#i@gmail.com (remove #)

Thanks

wat fan speed did u set?

I set the fan speed at super high lever (4 bar) and 22 degree. After switch on for whole night the operation indicator light still have 2 light, which means air conditioner is operating to reach the target temperature.

Only raining day, cool day the aircon indicator light will only have 1 light which means room temperature is approaching the target temperature.

We din check for the other 2 smaller rooms. I din see any water leaking from the pipes as all seal up with big casing and silicon, if leaking also not easy to noticed.

As the power point and piping routing should be check by Gain City, we don't know about this.

even the trucking is seal, if got leaking, there should be swelling or water vapour on the surface of the trucking.

not true. water vapour may not be visible from external trunking, for my case the sweating insulation pipes were noticed when the air-con installer removed the trunking cover. poor pipe joint connection and improper cutting edges may also cause gas leakage.

Hi, got a rude shock when I called Hong Tar in Enterprise Hub on Wed. Request 4 offer 2 replace my aircon. Quoted $2650 but bcos it concealed piping, the salesgirl inf they hv to make a visit to my plc. If I do not order frm them, they will charge me $30 for the sales call! State this is their policy and best I contact GainCity if I do not want to pay 4 sales visit. Ask to speak to her supervisor but "all r busy". Probably business too good. Contact GanCity - offer price $2140. Sales visit - no obligation. Sign with Gain City aft their salesguy visit.

which gain city branch u visited?

went to recee prices for non inverter aircon, was told that from 2011 onwards applicances with <3ticks will not be sold. mitsubishi non inverter also dun have energy saving 3 ticks (i went to website see also only got 2 ticks) & R410A gas type non inverter is new, store dun have. & the difference between the old gas R22 & new gas R410A is only a couple of hundred $$ how true any experts?

juz sharing my unpleasant experience wif IMM GC.
was there 2 weeks ago, served by this salesperson kelvin.
he has given us the quote (on a piece of rough paper - $4.9k) for starmex system 4 and i had indicated to him i am installing it at condo, meaning it will be concealed piping.
after 2 weeks of research, decided to go back GC for confirmation.
looked for the same fella and shockingly, he given us another quote which is $400 more, wif the exact same things i had asked for.
he say the other time he was not aware its concealed piping!!!
and concealed piping requires another $400 more?
was really pissed off by his attitude as well, he told us no stock for starmex island-wide. if i want, i will have to queue up.
i stood up and walked away.

aniwei, i will be going down to cck GC this evening, asking for the same thing again.
the reason y i am choosing GC is becos mainly of the $359 extended warranty.
most forum replies on GC oso fairly ok.

wish me gd luck lah!

my encounter GC sales is consistent in his quotations despite several visit i made before purchase... very patient, knowledgeable and professional. during installation find one ot the installer is not very approachable, abit negative and rude, reckless and rought in the workmanship. overall experience on their installation services - average only.

if dat sales guy refers to his so-called "bible", the price shld be stardard.
the most funny part is, he was referring to another brand price quote page, while telling me the price of starmex!!
then when i ask y the diff of $400, he says becos of concealed piping!
hope i can get some GC sales guy recommendation from here lah
thx!
