  • CU => A4UQ266FA0
  • BED ROOM BLOWER => 3 x AMNC09GD4L0 (9000 BTU)
  • LIVING ROOM BLOWER => 1 x AMNC18GD5L0 (18000 BTU)
  • K-Flex Class 0 Insulation (Not stated size of insulation)
  • 23' grade copper pipe
  • 16mm drain pipe
  • 2 time installation (F.O.C)
  • 36 mths workmanship warranty
  • $200 servicing voucher

Hi pal,

I believed all brands are the same as long as they are covered with at least 5 years warranty. Whether the compressor can last a not depend on luck. I have a friend that has a LG that last a couple of years. Some even use Mit electric, kaput in less than a year....

I like Daikin the most BUT just that it's price is one of the highest so :(

Make sure they used at least 1/2" insulator for r410a, ofcause 3/4" is the best :s13:

Copper pipe wise, G23 is ok (said by the installer) but G22 will be the best. Thicker can last longer and harder to have 'kick' during installation. I did copper pipe bending test for G22, G23, G24 pipes while they were doing the installation, each increase in gause made a great difference in strength of the pipes while bending them.

Finally, make sure they use new complete new coils of copper pipe for each fan coil. NO joining of copper pipes if can be avoided.

good luck

Mine is a single split. Brought from gain city for 989 with free 5 years extend warranty. Upgrade to 22awg add 20, upgrade to 3/8" armaflex add 20

Usage: 9pm to next morning 9am everyday. Electricity usage alone is down by 30%, i am using electricity usuage not by $ to calculate, cos the price per unit will increase/decrease.

i will monitor for the next few months and update again. Savings could be more

hi all, me again, forgive my noobness but i've some
questions on how to choose air con.

other than horsepower (BTU) & energy efficiency ration(EER)
what other factors should i consider when selecting air con?
good brands would be daikin, toshiba, wat else? & does color
of piping matter? seems like black is preferred. & if nxt
time for air con maintenance is go back to the manufacturer
correct? if have extended warranty worth it to sign? usually
air con warranty is 1 yr? 3 yr? thanks a lot for answring :s12::s12:

issit this model SRC25ZG-S / SRK25ZG-S (shown in coolserve)? then 989 is cheaper with 5 yrs extend warranty.

On avg ur monthly bill is agar how much? i just wanna have a rough idea.. cos i dun wan later my parents complain high increment on elect bill.

understand from the previous posts that AWG22 is needed for R410 gas due to pressure, may i ask wats the purpose of upgrade to 3/8" armaflex?

Thanks

default manufacturer recommend is 3/8". but for R410 gas, use 1/2" would be better, as the gas is alot colder than R22 gas. normally upgrading to 1/2" is enough.

another factor would be total compressor BTU enough for all fcu.

example, sys 3 - 3 x 9000 = 27,000. so if u wan the room to cool faster for all 3 rooms together, than hav to choose compressor which is around 26,000BTU n above.

i guess u mean colour is the insulation. any insulation they provide is ok. gd one is armaflex.

becos all the parts other than compressor is 1 year warranty. so if u scare tat the parts spoil after 1 year,than jus get lor. its all up to u to decide.

my samsung air con recently spoilt.

when i turn it on, it just off immediately. the LED light keep flashing. I call samsung service centre, they said the repair work may cost 100-200 + 50 for labour cost.

any recommended technician for repairing the aircon?

Ur Samsung aircon might ne the case of a faulty gas sensor for light blinking.
