Warranty on fancoil:

Manufarturing defect or product faiks to work within warranty. No including flap. Of they go and say ur aircon how long never service, show then the receipt to prove. If not have = dun have

Compressor warranty: 5 years

Condenser is the whole unit which has motherboard and such built in. Pcb dies, compressor running = no warranty.


Hope this clarifies ur doubt
hmmm, l hvnt checked with GC.. but i heard other co hv such term & charge not cheap for regular servicing, like 350++ per year.

To herman8210,

Some companies practise running both pipes in one 1/2 insulation.
Should be ok.
Another better option is the discharge pipe in 3/8 and suction pipe in 1/2.
As condensation usually comes from suction pipes.

In a dilemma now - old Daikin System 3 outdoor unit got error H8, understand that it won't be worthwhile to repair as there are quite a number of possible reasons for this error.

The problem is that the old Daikin outdoor unit is only 790mm wide, and I can't seem to find any current models that can fit into this dimension. There's probably only an extra 5cm or so space on the aircon ledge.

Anyone knows of any suitable replacement R22 brand/model which is small in width?

1/4 is too thin, min should be 3/8 insulation.

Not sure if OT so do let me know if I not supposed to post it here. For 2 trip installation, are we supposed to sign any documents after the piping and wiring are done?

3 fan coil aprox service charge 4 times a year is only $250 ma..
so cheap meh...luckily i did not sign for that 350...

i just checked GC 5 years Extended warranty. they say no hidden terms & condition or obligation. no need to engage them for servicing.
can engage 3rd party to do servicing. but if got problem, need to check if it is due to 3rd party.

and saw their promotion today. got Mitsubishi Heavy Industry System 3 on sale for $2499 with standard installation, is it reasonable price?
according to coolserve and the catalogue, this system (SCM60ZJ-S) has a maximum capacity of 25000+ BTU, but GC list it as 20500BTU..
am confused on this....if just 20500, then not enough for all of my bedrooms.
if 25000+, will be enough i guess.

please help to clarify this...

i was quoted Mitsubishi Heavy Industry System 3 for around 2600$+, with removal of old a/c and piping.

I would like to know whether this Mitsubishi Heavy Industry and the strongly advertised Mitsubishi Starmex are the same or not?

I was told by the Dr. Cool staff that both from the same manufacturer, but different dealer who market it differently.

If so, are the performance of both same specification of their aircon system the same?

Anyway, I just bought a resale flat that comes with Toshiba RAS-3M20UAX5. Searched on the internet revealed that this is a 1 tick non-inverter. My concern is whether this system 3 very power guzzling?

I also have a small upgraded utilty room at the back of my kitchen. The dimension is around 2.3 by 2.2 m, which I intend to use it as my gym room. I'm wondering what kind of cooling system I can install that would not take any space in the room?

Please advise.

Thanks.
