AC working intermittently

[MADT]

Hi all.

Just wondering if anyone has experience intermittent faults with the AC?

AC usually works fine but occasionally it simply wont get cold. I have to turn it on and off and the heat up and down and eventually it will get cold. I haven't been able to work out what triggers it to start working again, I just switch things on and off and up and down.

I have had it re gassed and it has made no difference. I had them check it when it failed last time and they confirmed that the compressor was actually running but no cold air was being created.

Any similar experiences???
