DIY car AC recharging is risky because there is no way to know if the system is overcharged or undercharged, and sealants can damage AC components.

Existing DIY AC recharge kits do not provide any feedback on refrigerant pressure or charge level, leading to potential overcharging or undercharging and long-term damage to AC components.
