If you hear your air con making noise suddenly, you should switch off the air con as soon as possible.
In our experience, it have few reasons cause the noise,
> some lose parts
if the fan, the cover or some plastic or screw is not tight enough or if you unit is too old/ ageing it have this problem.
> something stuck inside the machine
If you are living in the country side, you might find some Gecko / Lizard inside your room, it will go inside your air con sometime, make sure you clean the filter and check the machine regularly to avoid lizard live inside it. Sometime the rust form the coil part will fall in the indoor fan to create the noisy. If you stop the machine can avoid it damage the air con as well.

While technician install the new air con, they should avoid install the water pipe directly to the main dirty water pipe. They can connect it with U-shape trap.
