"Het Pumps not suited to warmer climate"
This is not true. The principle is that a heat pump grabs available energy from the air from -273 degrees (0 degrees Kelvin), the warmer it is the more energy available to grab the more efficent the heat pump becomes.
As for the noise there are only two moving parts in a heat pump the fan and the compressor. Of the two the fan could make a screeching noise if it was running a bearing, otherwise it would be reasonable to assume the noise is not fan related. Therefore in all likelihood the noise is from the compressor.
A noisy compressor usually indicates the gas pressures are not correct in the unit. If the gas pressures are not correct in very little time at all the compressor will fail.
In your position I would suggest to the property owner his first step should be to employ a refrigeration mechanic to check the gas pressures this may solve the noise issue for you and should only cost a few hundred dollars. He can then take the builder to task through the BRB or whatever on the basis that the unit should have been checked post installation anyway.

The heat pumps are for the warmer climate but as Mark wrote before, they are not suitable to run during the night.
After a long battle we pushed the installation service to check the unit and they said everything was fine.
Within a fair distance of 1.5 to the fence, 3m from the fence to the side of the house and another 3metres to the window the level of the noise inside our bedroom was 42 decibels and I am deadly serious.
Normally we have 22 decibels.
The thing is:
-always buy a good brand and always check specification of the appliance.
Be smart then you will save money.
