  1. price $280 to $350. what is the btu of your air con?
  2. if you live in HDB i think u can consider to change a/c , daikin non int is 3ticks price is around $1800 to $2100. if you live in condo then you must do a pressure test to find out the point of leak. due to air con pipe is hidden in wall/ceiling pressure test for your system 3 i believe is about $390.
  3. wah... you really have a big problem.. it really cost you alot to settle is problem.. ic board, wiring, or compressor either one also will cause trip. only when on all three air con then cause trip? how about you on one by one.....? on 1st a/c wait 15min after cooling, if no trip then switch off now try on 2nd a/c wait 15min after cooling if no trip then switch off then on 3rd a/c wait 15min after cooling if no trip then switch off if tested one by one no trip then wiring should be safe. now left with PCB or compressor ? compressor over amp or shorts Earth also trip.. you need to check compressor amp and mutli meter to test. wat your daikin model? 3mk75 or 4mk75? on on 2nd
  4. what is the (brand of ur air con / age / model if you know)? can be compressor PCB faulty or base expansion valve that control the gas flow or contactor jam. not easy first must know what ur air con ? http://www.bencoolservices.com.sg
  5. i believe i can help u with that, can u take some photo to show me the water mark is? on the casting? i believe u run system 3 = 6 copper pipes squeeze in the casting, cause the inslulation press again each other then condensation http://www.bencoolservices.com.sg
  6. easy. 1) this the unit on almost every days? as i believe it might need chemcial wash($70) off your air con pull the swing flag and use light shine in side the air con is the fan blower chock? Air con heavily dripping i still believe is choke. 2) have to on another air con to stop water leaking main pcb faulty? come diy your self. on the bedroom 2 air con only. 5min later compressor run. walk to the driping air con step on a chair lift up front cover by two hand, then take out filter touch the coiling coil freezing or nothing? driping air con is off mode so coil shouldnt be freezing. if yes 70 percent gone liao. if no haha lucky pcb working fine, change company to svc ur air con. Bencool Services. visit my blog http://www.bencoolservices.blogspot.com/ see what is chemcial wash b4 and after. new toshiba air con....erm.... got one problem is water tray is fixed so maybe the tray got choke block the water flow down the drain.
  7. If thermistor sensor faulty, daikin air con will blinking when u on the a/c for out door thermistor faulty error code is C4. to check error code when blinking press and hold "mode" and "up" "down" button together.
  8. example system 1 run at 68PSI R22 gas. and your system 1 left between 30psi to maybe 48psi it will cause ice form on the coil, when a/c running at high speed the blower in-take the air from the coil, its puts again the ice from coil and blow it out. if gas level low maybe between 30 to 48 psi, cause ice on coil, and it cause the copper pipe on the left side of the condensor unit have ice too. and if condensor unit no ice, only fan coil unit have then most likly is ur fan coil unit need chemical wash $70.
