thx bro~

Heads up: was informed by contractor friend whose friend in the trade shared something interesting about newer installations of AC. Some AC in particular require 4 wires over the traditional 3. The additional wire is an extra neutral from DB box to compressor.

Samsung AR triangle series is one prime example. If the fourth wire is not present, they start and after 5 minutes the following error flashes across the led display "E 01".

So for new renovation or if hacking out and fitting in new pipes, put in 4 wires. You never know when it's going to come in handy.

Dear Sifus...a good day to all, I'm going to start to renovate my house, thus I'm looking out for shops which sells AC units at reasonable price around KL Kepong or nearby areas. i haven't surveyed as yet. Planning for split units.

Any recommendation where to get at reasonable price and good service would be much helpful thanks

Does all of the new AC unit need the 4th wire? abit confused why need additional Neutral when there is already one??

I prefer Yorke instead Panasonic.

Thanks will check out ESH :-)

After 2 yrs = noisy wow

Need go for service frequently for avoiding noisy sound

No mater how you service, but the parts just last you around 2 yrs usage only

It all depends on brand and model. The older AC thread here way back in 2012 on pg 109 and pg 110 where Kelv and skng03 also talks about this. At least 4 wire some 5 for inverters. 3 core for LNE. Extra 1-2 wires perhaps for interconnect and advanced signaling.

If there's no need for it, all's hunky dorry. The problem is when it's required like the situation I was told about. The point is about future proofing. Most times it's not needed except when that odd situation arises because of a peculiar brand and model. In this case, it was for Samsung 1 and 1.5 HP inverter AR[09/12]HVSDBWKN. Both utilize 4 core wiring at the least which was a bit unusual as most other R410a inverters are only 3 core of the same HP.

4 wires & used 0.6mm copper pipes G23 will be more save.

If wanna used G22 = 0.7mm also can.

Hey guys,

my budget is below 1k...

can recommend me good and energy efficient aircond?

right now i'm eyeing on

ME SRK09CM 1HP
Sharp AHA12PCV 1.5HP
Panasonic PC12KMH

I'm really noob, dunno nothing yet about air conditioners.

How bout York inverter 1hp?

i need a 1HP air cond, budget around 1k or less, which saves energy and less maintenance in long run.

any brand?

Panasonic, York Cooling King, Midea, Haier, ME, MHI, Daikin, Electrolux, Sharp, Hitachi

Which one TS Prefer?

wah still a lot of options... inverter or not hmmm

All brand have inverter, but only top up another Rm300 extra then you can enjoy 50% energy saving

I heard there's 2 inverters..

Digital and Linear/Analog inverters..

what are the difference?

I'd really love some recommendation for

a really good BTU : EFFCIENCY : PRICE ratio

with a price tag <1k or 1k++

I knew was DC or AC only.
DC more energy efficient and quiet.

AC nobody used already, even autogate or water heater was running DC now.
