Anyone have approach contractor or aircon installer for the copper to be conseal into wall before aircon installation?
I have 3 bedroom + 1 Living room. I would like to know what is the price per feet for below:
1 HP aircond (non-inverter type) (Guestroom)
1.5 HP aircond with inverter type (master room)
2 HP for living room (Non-inverter type)

I find majority of lowyatian mention that non-inverter will use different copper right?
