New Starmex Aircon Condenser Unit Noisy

[blwc 0]

Hi ,

Just installed ME StarMex Inverter System 4 and the condenser unit is not as quiet as claimed ...

Living Room FC = GA22

3x bedrooms FCs = GA10

Condenser Unit = 4A28

Living room is only abt 6m x 4m (LxB).

Upon switching on living room Fancoil (GA22) with lowest fan speed ... Condenser unit will slowly become noisier and noiser ... it's loud in the night especially. If fan speed is changed medium or high ... Condenser unit immediately operate loudly.

For bedrooms (3m x 4m), if only 1 bedroom fancoil is switched on with any fan speed, the condenser unit is operating at an acceptable noise level. However, if 2 bedrooms fancoils are switched on, the condenser start to operate loudly.

The noise level is worst than my previous 9 years old Fujitsu non-inverter system 3.

The ME starmex inverter system is installed by Gain City.

Is this normal for inverter air-con system?

Anyone having the same problem when using 4A28 outdoor condenser unit? Is this an installation problem or hardware problem?

Confused.
