U tried to stick at both clip area and center put thicken rubber to be touch to inside front cover.

Ok will give it a try again.

Btw, do you think i can ask panasonic to give 1-1 exchange for the condensing unit?

B'cos yesterday even after they paste sound proof insulation inside the condensing case covering, the sound still exist. It is like coming out from the compressor itself.

B'cos if the sound problems exist fm the coverings then it will definitely solve it, but it does not.

Can try to write letter or email to the main service center and requested to exchange for outdoor condenser unit.

Because it is still new all of the times to solve and service and didn't solving for you, and very dissppointed for all those panasonic product I won't continous for support anymore.

Just using 3-4 months right now and get the worse product from panasonic.

Make more complain.

Panasonic came again.

Their specs stated for outdoor unit is 56db & indoor unit is 36/26 for high & low respectively.

And guess what they told us for outdoor unit they will measure fm indoor 1m away fm room window so for our case is 46db so consider normal?

But we don't agreed & feel that they are giving some excuses etc. Then what is the purpose for them to classified outdoor unit sound level & indoor unit sound level?

But even though they paste sound proof insulation surrounding the compressor, the sound still persist? We asked them if it is due to the grille in front of the fan but they say they check

and it is ok.

because panasonic non-inverter compressor will be have much more vibration to compared others brand.

below i show the photos can be added additional insulation sheet into compressor.

so can be reduce much more noise when compressor are runing.

non-inverter model look like.

just to share with my experience,

i stay with my mum for a year before i shifted house recently, her 8 years old Carrier aircon was so noisy that i had to stop my brother from using the aircon in his room as i am stay in the Master room where the compressor is installed outside the window. Its like whao whao whao sound everytime the air con is on....imagine i suffered for at least 5 years.... eith that kind of sound.

When i installed the Panasonic inverter system 3 CS-MK27KKWZ at my new house (a resale flat) . This kind noise disappeared even i switch on all 3 indoor unit.... it is surprisingly quiet.....

maybe the installation of your air-con have some issue that generate noise . For me i had got a very reliable air-con specialist to do the installation job.

So far this panny air-con is super quiet and do not disturb my sleep less my neighbour above me always walked like elephant gong gong gong.........

If you need to ask my air-con installer to take a look at your aircon let me know.... u need to ask how much he charge you first hor...

Check this forum http://singapore-aircon.blogspot.com/

i had checked the website and maybe the fact that using non-inverter air-con can contribute to more noise that inverter version.

i think so as my mum's air con is the non-inverter version which is so noisy....

for all those inverter compressor is difference technology can be runing variable speed.

even u set in 25C or lower temperture for the compressor can be follow your setting speed.

condenser fan speed also can be variable +/- 3 dB-A. speed.

to compared non-inverter everything runs in fixed speed.

when operation is longer for compressor will getting hot and have much more vibration in whao whao whao sound.

without reduce compressor speed and condenser fan speed are fixed also.

so you can't near to the fan blower grilles it is heat air same like hair dryer.

not like inverter fan speed is +/-3 dB-A. you can touch to the fan blower grilles it is cold.

so you can imaging why non-inverter will be using heavy energy and noisy because all in runs for fixed speed in same RPM until you switch off your aircon.

non-inverter compressor still using AC type, for inverter are using DC rotary type.

I was using Carrier non-inverter system 3 (68CNMR321) for 5 years plus before i change to Panasonic non-inverter.

For Carrier set the compressor is quiet, what i mean quiet is it does not generate any unwanted sound into the room when in operation. As for the fancoil i think is relatively quiet too.

I am not sure if it is due to installation or machine fault. Gain city blame on Panasonic & Panasonic say installation + pipe problems as i am re-using existing piping. The masterbedroom previously piping is for 12,000 btu fancoil whereas now Panasonic piping is for 9,000 btu fancoil. But during the day of installation, Gain City technicians did not mention anything.

However if i on the 3rd room which use the small compressor, the drumming & vibrating sound is there although the pipe is correct. The compressor sound fm this room is relatively lower than the masterbedroom but it will still emit into the room from somewhere, don't know fm where?

Now we got no choice but to sleep in 3rd common room so that not able to hear the compressor runny noise only the fancoil sound.

Yes panasonic technicians did wrap insulation around the compressor but it did not solve the problems at all.

If you say non-inverter will have more noise or vibration, then how come the Carrier brand non-inverter that i use previously not noisy at all. Or maybe only panasonic brand non-inverter more noisy then other brands coz the unit is very big and tall?

What's the difference between 2.5hp & 3.0hp.

And i read the specs for Panasonic non-inverter for compressor it stated as rotary (1 cylinder),rolling piston type and as for Carrier non-inverter is 2/Rotary with fixed speed.

Will all this contribute to more noise etc.

Actually panasonic currently non-inverter compressor all made in china already.

They just used the same previous technology until now never changed.

All those Aircon companys already focus into inverter compressor. If you can get the eco scroll compressor it is the best in markets for most quiet runing operations without any vibration and noisy.

Cause non-inverter compressor still used the AC motor and single rotary type.

As now Carrier taken over by Toshiba, what do you think of Toshiba non-inverter aircon? Their specs stated twin rotary and if i am not wrong, Carrier previously non-inverter aircon uses twin rotary as well fixed speed for non-inverter.

How abt Daikin, is it better?

Yap daikin is better their using own technology called hermetic sealed swing compressor.

For outdoor fan can be reduce -3 dB for night time.

So totally very quiet.

So do you mean for both non-inverter or inverter Daikin will be quiet as compared to other brands? Pls advise. Thanks!

I cant confirm daikin will be most quiet for brand new yes after due to usage every day switch 8 hrs I think the noisy will be problem again.

To compared non-inverter and inverter more quiet operates cause it is using DC motor compressor and twin rotary. Mitsubishi starmex inverter also very quiet at 46db only for outdoor.
