If you’re concerned, Eric, it may be worth taking it to an Aircon specialist.  Catching a problem early is always cheaper than rectifying it later.

But did the loud sound gradually go away?  Just wondering if it was as simple as the aircon set on auto and having to work particularly hard to lower the internal temperature?

What sort of a sound - screechy, clicky, rumbly? Can you take a recording of it and post it up in here so that we can hear what's going on?

Just started suddenly last night, very rumble!

I will just try aircon specialist.

[Eric71]

Very rumbly!

Hi it is me again. Strange loud noise from aircon has just stopped ! I don't understand. One way or another I will visit aircon specialist. Thanks for your replies.

Might be worth pulling the filter and seeing if there's anything stuck in there that might have been causing the noise, which has since moved.
