Insulflex (with an L between insu and flex) is standard fare. Don't get Insulon or Superlon as they are nowhere as near in performance. Some places do sell K-flex (Italian) which is also better but pricier.

Thanks sifu halcyon...

So, is it OK for me if I choose York Inverter instead?

No compulsion bro and if I seem pushy, my apologies, entirely your choice. Just sharing what's available out there.

Thanks again sifu.......

You're welcome and please don't call me that. We only share our experience here.

Wow, I've found something new..(as for me)

Fujiaire 1.5HP (R410A) Air Conditioner FW/FL15V9B5 Wall Mount Inverter (Diamond Stars Series) @WIFI

this model, u can control it with ur handphone

juz install the wifi then u can control ur aircond with ur phone, even tho u are at ur office...

Is this an advantage or disadvantage?

There is a device call LifeSmart SPOT which is an IR transmitter shaped in a doughnut LED designer table piece. It works for tv, AC, fans or any devices that uses infrared and within its transmission range. Head over to the Smart Home thread as it is extensively discussed there. There's also a dedicated thread to this brand.

AC is best to stick to cooling performance, economy (measured through energy efficiency ratio), reliability and air hygiene enhancing features.

Hi, I'm using a few R410a York 1.0HP inverters (purchased 2 months ago) and it has gas leaking. We have been doing basic leak test (check bubble @ exterior pipe) & refill gas, after a week and the gas leaked at least 50%.

I'm scratching my head now as I've no clue what's wrong with it as there is no bubble @ the exterior pipe. Would it be leaking in the interior unit?

I wonder if I approach York, will they provide a more advanced testing?

Leakage can develop anywhere even embedded. If the piping had to bend from blower to compressor chances could be where there is a kink at the bend. Get another installer to verify. Are you in KL?

Worst case scenario, change the pipes. Use better insulated piping as well as a skilled installer.

Unfortunately, I'm in Melaka. I wonder what's the normal rate for the insulated piping for pipe leaking?

I think my contractor workers collide the compressor coil while doing renovation thus internal leaking.

Do I have to select York authorized installer? I have York & Daikin over here.

Not necessary but if you want peace of mind you can call them and ask to recommend. I found mine through my supplier and have been employing his services since.

Thanks.

The existing contractor, when asked, he just say the normal layout out, 2 in one insulation is workable for invertor without issue.

K-flex
Insulflex

will ask around next time

No don't go that route. That's mixing. Insist on individual sheathed. I gather you may need to hack to widen. Wrapping two in one works but the AC will operate higher. That's the normal complaint why ppl complain inverter don't save. Two pipes with the refrigerant in different phase wrapped together in one insulation equals mixing. The compressor works harder that way.

my apartment comes with non-inverter piping and wiring.

anyone know if i want to install inverter ac do i need to hack wall to redo piping and wiring?

thanks in advance!

care to share ur contractor? or can you ask him if he install in senawang? how much he charging for installation of 1.5hp daikin inverter.

since i will be moving to new area and i do not know any reputable installer, might as well try the one recommended by experienced guy here.

Thanks, then I think I can only ask them to hack the one beside the wall, only add in one more hole.

For living room, compressor and FCU is located back to back, so very easy to reinstall the pipe. But since the space is big, I don't have any plan to upgrade into inverter AC, cause the AC will work harder but will never reach optimal temperature.

Commonly many models of 2.0 copper piping internal diameter utilize 1/4"(6.25mm) liquid and 1/2" (12.5mm) gas.

Not all models utilize this size for the rated cooling capacity HP ie some manufacturer's models can use larger than typically found e.g. Sharp 1.5HP uses 2.0HP pipes of others. Others even could be smaller than the typical e.g. Daikin 2.5HP can be drop in upgrade for other 2.0HP as their gas pipe internal diameter is 1/2" (12.5mm).

If you like, upgrade piping to one size bigger ie 2.5HP which commonly utilise 1/4" (6.25mm) liquid and 5/8" (15.8mm) gas. This way you can still use 2HP then upsize to 2.5HP next time. Some like the Daikin runs 3.0HP on this common 2.5HP pipe diameter esp the FTKV70.

Useful note: copper pipes connecting the compressor and FCU can be bigger than spec but never smaller. Always follow manufacturer drain hose size. For new I would always go for 19mm (3/4") internal diameter. Typically some use 5/8" (15.8mm) but larger ones have better clog free assurance.

I've pmed you one based in Kajang/Semenyih. Not sure if that's near. The one who did my kids room inverter with Smartco Paircoil piping is no longer in this line having injured himself in 2013. The contact is the still active colleague that he had given me in 2015.

One way you can ask for installers contact is to go to AC/ refrigeration equipment suppliers around the area and ask each to recommend. It's good to have two or three that are near the locale where you're located but to vet if they're good is purely by luck. I've to admit that the one I engaged the first time was very good, honest and conscientious but is limited to within Klang Valley esp MK, PJ, Subang and Puchong.

Anybody using those portable airconds? Came across an Acson 1.0 hp yesterday and was impressed, thinking it would be more than sufficient for a small room. Anybody using one?

The hot air as a result of the rejected heat must go somewhere. If not mistaken, they have a ducting which must position elsewhere to vent the rejected heat?
