I had my brother help me charge my AC with artic freeze, long story short he overfilled it, instead of psi 45-55 it's at over 100. How do I reduce the pressure?
I would think you'd need a proper R14 pressure manifold setup to lower the pressure to a set amount, and I don't recommend venting to atmosphere for obvious reasons. What damage can be done if the system is overcharged? How are you measuring the pressure?
