I suspect your wiring between compressor and fcu broken/shorted.
thanks for your help.
actually i did get the service man to check and was told to change compressor pcb and all the wiring.
i like to confirm the pcb fail or else is purely wiring problem then no point spend the extra money for pcb or change whole system.
it look like 1 of the wire burned out as it had darkened color.
the other 2 wires look ok
i cut off one of the look ok wire to do test/trouble shoot and think likely the compressor pcb and 2 fcu failed.
i change the wire and try switch tested around different connector outlet to different fcu.
only 1 fcu able to on but after awhile it will shut down and fault code come out. the other 2 fcu totally cannot on.
think it time for a new system.

I found this shop in Toa Payoh last year. The guy is a nice guy and no hard selling. Believe he was a Mitsubishi Heavy Ind dealer as he kept recommending this brand. But generally he leave me to make a decision on which brand over the weekend before committing.

I took MHI System 3 aircon ($2,880) on his recommendation

Toshiba Aircon is under Carrier if I'm not wrong, thus not affected with Toshiba withdrawal from Singapore.

To cannotliao,

Then better assess first before replacement.
What brand is your aircon?

Hi,

Is this quotation reasonable?

Model: MXY-4A28VA / MSY-GE10VA X2 + MSY-GE13VA + MSY-GE26VA (30,367Btu) - $4,450 incl 7% GST

To supply labour & material to install 1 set of Mit StarMEX inverter multi split wall mounted type A/C complete with 1/2" Thermaflex class "O" insulation, refrigerant copper piping, diameter 16mm drainpipe, 3 core 40 Keystone control wire, 2.5mm wiring from condenser to isolator, PVC casing at expose area, vacuum system, charging in refrigerant gas, testing and commissioning

Compressor 5 yrs, Fancoil/Spare Parts 1 yr warranty by agent.
Installation workmanship 1 yr warranty.


From the same company,
MXY-4A28VA / MSY-GE10VA X3 + MSY-GE24VA - $4,390


Price difference of only $60 for following changes:
MSY-GE26VA => MSY-GE24VA
MSY-GE13VA => MSY-GE10VA
Err... so little price difference? But in the first place, is the quote considered reasonable?

Also, can any air-con guru advised if 9000btu enough for all bedrooms & 24000btu enough for living room based on the following area?

Currently air-con is on mainly in master bedroom but with kids having their own room in future, all 3 bedrooms may on air con at the same time at night. As for living room, currently doesn't have any air con at all, so may just on if there's any gathering or when weather is extremely hot/hazy, which probably only on during the day time. At max, living room cum 1 bedroom will turn on at the same time. Is 28VA compressor enough?

Master bedroom - 14.4m2
Bedroom 2 - 13.5m2
Bedroom 3 - 13.68m2
Living room - 33.6m2
