Is this a sound of gas leak? The technician mentioned it's part related and expected as this is a really old AC. Can someone please diagnose if that's the case? I have 90 days warranty to call him back if it's a gas related issue, since I refilled this.
This is an 18 year old LG, oldboy was our 1st one.
