If our Window AC is Leak how we can find leak and fix. We will give AC pressure 300Psi to 350Psi , we need some tools for pressure
one Line connect with gas charging valve and second connect with vacuum pump, if we dont have vacuum pump we can do with any old compressor and pressure should be 300Psi to 350Psi (1.5 ton window ac)
After pressure we need Foam water and spunch, now we drop water with spunch on joints and from where will be leaked there will be make bubble and we can repair with gas welding.
