@Imsonali0 Every year it was just top up of gas. Now the Urban Clap guy says, he has to drain the earlier gas and fill it fresh. Otherwise there is a risk of a 'blast'.
I have politely sent him away.
Nevertheless almost all ACs' gas 'leaked' according to them.
@SandeepMall Heartiest congratulations on the splendid organization of the Bhagwat Katha! Your dedication shines through every moment. I'm catching up on the katha bit by bit on YouTube each day—truly inspiring.🙏🏻
