I'm actually wanting to find out on the copper and aluminum pipe thingy
aluminium is least efficient in heat transfer then copper, it is actually a downgrade.
Gold > silver > copper > aluminium.
It's material is lighter then copper which suggests during installation, the chances of refrigerant leak is much higher due to bending
Class 0 insulation is an overkill, class 1 will suffice, and always run the electrical wires in a separate conduit as some contractor will use cheapo china copper wire to run ur indoor unit which sometimes will catches fire, witness b4.
Got it, i rang them up and they say it got higher PSI than copper, produce less condensation. think i will call them up to revert back to copper since its a free upgrade.

Any problem installing a 15A air con system that exceed 8.5A provided in old HDB flat??
is it better in the long run to pay the $180 for the copper pipe?
$180 should be for copper + insulation (1/2 inch) upgrade.
