These referring to York's model equivalent? Even those are ok.
If they refer to high fan mode noisy, all are like that. Use only set temp and compare.

In my old condo, bedroom no fan point. Relied on then Thai made Daikin R22 inverter. Set to 26°C. Very quiet at set temperature which it maintained. I hear traffic from outside my window than my AC (rated 26dB). That AC has sleep mode and compressor quiet mode. Slept right under AC.

That AC has five fan levels and fan only (air circulation) mode. Only thing is not equipped is anti mould cleaning after use which the newer R410 gas inverters have.

Btw, all AC compressors are noisy outdoors. None below 44dB as far as I've surveyed. That's quieter than many washing machine if putting things in perspective.

The implementation of anti mould cleaning is straight forward, where the fan rotate at the very slow speed after you switch OFF for 1-2 hours until the condenser fin dried up. You can simply switch to fan only mode (air circulation) after used at slow speed for 1-2 hours will do the same thing.

Your R22 unit is one of the best production. Keep it up to maintain. Pretty sure is more than 5 years

Yes, eleven years ago but sold with the condo but used its 2.0HP Thai R22 F???50GVM, a newer generation sibling in another place after that. Sold that place and moved to a condo now using Samsung Triangle inverter and Sharp Inverter. Both have clean mode with ionizer.

Wow, good to know and thanks for sharing that tip.

QUOTE(krayzie @ Jul 7 2017 @ 06:04 PM)
no problem with that.
I'm more curious if daikin was really that bad? As in really that loud and that many strange noise as they'd mentioned from user experience?
*
And lastly, sometimes noisy could be attributed to vibration. Vibration dampening pads could help also. If possible if you've not installed or laid pipes, use Inaba Denko's Paircoil. These are individual insulation sleeved copper pipes that are very durable as long as installed rightly. High quality copper. That very likely will eliminate vibration due to pipes knocking about in their embedded space inside the wall. Individual sleeve combining both gas and liquid pipe will experience knocking against each other in addition to mixing hot and cold refrigerants. This can cause the compressor to work harder in coolong and damage the cooling fins in the indoor unit where you see ice forming and causing the fins tip bend with tak tak sound. Individually sleeved jacket causes the AC to run at its rated power.

Thx for all feedback.
Just want to make sure it is 'money' in play here that those electrical shops trying to damage daikin brand. Went to 3 shops all said the same thing despite not trying to push for the same brand.

They are found in many AC / refrigeration specialist (not the regular electrical appliance) at least from PJ. Usually Superlon is widely available but that's roll on or slip in which is still very loose fit. Try Allco Parts in Kelana Jaya. There's a Korean one same trade name made by Smartco. Get the one meant for inverter or R410a.

8 units still can consider split type. Vrv unless you have more than 20 units or if you're loaded you can consider.  The outdoor already cost about a low spec myvi. I've installed about 2 system in a bungalow. The quote is already 300, 000++

The mix and match would be depends on how many hp you need in each room or hall. Then only they will select the outdoor.

If you're interested in vrv system you can go for the mini vrv. Is just a compact model of vrv the outdoor also smaller than the usual vrv

If I'm not wrong daikin has this model for 12hp or maybe higher. You need to check with them.
*
Just get more information about vrv system. You are partially right
Based on the information given, the price does not cost about a low spec myvi, maybe you are referring to commercial type vrv, for a residential type,
a 9 to 12HP is about 10k for the outdoor unit, maybe this is your so call mini vrv.
For my specification, the quotation runs to about RM50k, or maybe slightly less.
But compare to normal air cond, the cost will only run 20k. so vrv system is till 30k more expensive

The good thing about a vrv system is 1 compressor can drive up to 10 units or more, and the piping length can be very long. Good for condo with not much ledge to place aircond
The system get economical if you need to cool large area, 2HP and above is the place they shine, anything less is expensive.

Just asking, my existing house got 1 aircon. If I want to install extra 1 aircon, do I need to upgrade the electricity box??

Just add a mcb point and wiring to the aircon. Std procedure.

Your installer might tap from your room wall socket. If the aircon is 1hp.

But you have to check by yourself are the room wall socket is fully occupy or heavy loaded with electrical appliance.

I'm looking to buy a new aircon and i thought daikin is good brand. But some how went to a few shops they kept commenting that Daikin aircon is very noisy.
Asked them what noise is that, they said the inside unit wind blowing sound and compressor also very noisy.

Is that true Daikin AC very noisy?

By the way, a few shops kept pushing for Electrolux. I hardly heard of Electrolux famous for aircon. Any opinion about their AC?

All 3 different electrical shops tried to convinced me it's noisy and try to ask me to switch regardless which any other brand seems to be better than Daikin.
I guess is the commission.

Hitachi also except when put to silence mode. Even at auto, it's just as noisy even when reached set temperature.

Dear All,

Headache now.

How to hide all those drainage piping if the current is not allowed to be hacked?

Any solution? Do not want those piping expose outside. My contractor told me aircond drainage pipe must below the aircond position due to water flow reason, thus it cannot be hidden at above and inside plaster ceiling.

Even now plaster ceiling also cannot resolve this. Anyone staying in condominium have faced this issue before? How uou guys resolve it?

Appreciated for your suggestion. Thanks.

AC pipe will sweat (condensation of moisture in the air) and naturally the drain is there to conduct the condensate away otherwise the room will flood. Hence drain always positioned lower than pipe due to gravity affecting where condensate flows: downwards.

Why cannot hack? If AC pipe too low vs drain, solution is to hack where the drain pipe is and position it lower than AC pipes. What's the constraint?
