For the last month I have been in southern Spain and have a rented flat which is near the air-conditioning fans for a big complex. Normally, this is so quiet that we do not notice it. Suddenly, earlier this evening, it was making so much noise that it was like a jumbo jet taking off!

I vaguely recall that this may be part of a cycle and is to do with de-icing or something? Are we likely to get more such noise as the weather gets hotter? If this is just a few hours per week then no problem but if all the time we will have to move!

Sounds like a call to a service engineer would be the way to go...

Does it sound like something is speeding up and then suddenly slowing?

If it is then the bearings on one of the fans is goosed.

Does it sound like a loud whooshing?

In this case it is the defrosting and would be time to move...lol
