Need help identifying strange AC Noise *Video Included*
Recently had all sorts of issues with my AC.
After a re-gas and chasing an non existent sensor I have now developed strange AC behavior.
Seems that on occasions the econ light comes on. When it's off and the AC is running a sound of gas running through the pipework can be heard whilst on low fan setting.
I have attached a video and press the econ button mid way which stops the noise, byt once the AC is started again the noise starts up again.
Here's the vid let me know what you think.
