For anyone using panasonic, how is the noise level of the compressor (those staying in master bedroom)? If the sound level is within tolerance level, i might want to purchase system 2 or system 3 of this..

I consult with coolserve and they say that Mitsubishi is still the most quiet compressor among all brands. I have verified this when I visit my friends place, ME and MHI has a very quiet compressor. You almost hear nothing... at most you hear your upstairs neighbor's noisy compressor

mine lor, same as the one in the above post... just that mine is single split

so the compressor makes a big difference.. i guess maybe sys2-3 will be bigger hence "louder" noise than single split?

mine also almost cant hear anything.... opened the window n hear... very slight noise .....if window closed very hard to notice also...

Actually it's quite silent. I'm running the same model above too.. But system 2.. When i got back from work and when about go into my master bed room for bath and i never heard any sound ..so I thought that it was switched off the window is wide open btw.. But when I go to my other room I notice my air con are actually running

Hi all, my case is different.

I don't know for me if it's worth investing in inverter as I strictly stick to timer and use only 2-3 hrs per night. Room a bit cold can liao, once I sleep and it switches off, heck care the temp after that.

My home is System 3. All in bedrooms only. Will prob be moving out in 2 yrs if getting married. After I move out, prob only my mom will be left and she won't use the aircon much, maybe once a month for a few hrs if weather gets very hot...

Was thinking of 2 theories... 1: buy the cheapest possible (e.g. Samsung $1399 2 ticks from Carrefour this kind) and treat it nicely, few hrs per night and hope in 3 yrs it's still working
2: buy a more reputable brand with 3 ticks e.g. Toshiba which cost $1800+ , if it turns out more reliable or really more efficient then at least can say I recover back the "savings" (but I would never know)

Anyone have any opinions?

P.S. Would love to hear recommendations or complaints on aircon contractor too.

Steel bracket

Hi,

My outdoor unit has been mounted on a steel bracket for the past 13 years. Of late, I noticed it slants about 5 degrees to one side, i.e. its not completely level horizontally.

My service guy noticed corrosion/rust on the inside when he removed the side metal cover for servicing. He advised to replace the outdoor unit (effectively the entire aircon system) for safety reasons. When I looked at the bottom of the outdoor unit from a few floors down, there is no rust.

I would like to ask if its possible or practical to get an installer to do a check / replace just the steel bracket. Anyone knows?

Appreciate any relevant info.

Thanks & Regards!

Our factory reported the following;
1) The reason why pre-heat is necessary
• Compressor pre-heat function is equipped to MXY series in order to prevent liquid refrigerant accumulation in compressor that causes damage to compressors.
• Pre-heat function improve the reliability of compressors and contribute to reduce the defect caused to compressor. (some may impact long term energy performance also).
2) Pre-heat pattern and power consumption
• Pre-heat is switched “ON” for 20 min and “OFF” for 40 min in an hour when ambient temp is over 21 degree.
• Average standby-power is 20w (when pre-heat is “OFF”) and 80w (when pre-heat is “ON”)
• Of course stand-by power is not applicable during operation.

Exclamation

Any bros & sis using this brand & model now?

Panasonic Non-Inverter System 3 (CU-3C20KKZ / CS-C9KKZW x 3)

Is it noisy & how's the peformance? Is it better than Toshiba or Mitsubishi?


HI All,

I just brought & installed Panasonic Non-Inverter System 3 ( CU-3C20KKZ ) on Thur, 16 Sept & already encountered 2 problems on Friday & today! I am so angry & total regret buying this system.

First - Problem with my aircon system - not cold at all even if you switch to less than 20 degree! We are all perspiring in the room. It turns out that the gas was not enough!

Problem today - the timer keeps blinking even if I have not touch or set any timer at all. The system switch off in the mid of the night automatically. I on it again & it switch off another 30 mins later. On again & off again ... I am so piss off! Worst, the technican can only come back again on Monday! I will have sleepless night today & tmr just to on & off the stupid system.

Any same user facing the same problem? Can pls advice how to solve it? I have reset the remote controller, take out batt, use another controller - all useless.
Pls advice? Thanks

Well, im using the latest panasonic system 3 inverter, previously i was on non-inverter sanyo system 3, electric bill dropped from 290 average to current 200 a month with the same amount of usage...
Hi,

You are using Panasonic System 3 Inverter CS-S9JKZWx3(CU-3S27JKZ) or CS-3S27KKZ?

How's the performance and the Compressor is quiet?

Hope to hear you comments as I plan to install it also.

Thanks.
