Super Tech Premium R-134a Refrigerant vs Interdynamics Arctic Freeze R134a Refrigerant

The Super Tech Premium is the better pick for most DIY recharges because it bundles a reusable hose and gauge, so you can charge and check pressure without buying tools. The Arctic Freeze AF6V adds a leak sealer and moisture eliminator, which helps a system that is slowly losing charge or has a small leak. Super Tech scores 4.1 from about 1,049 ratings; owners like the included gauge and the PAG oil with conditioner, though some report the gauge reads roughly. Arctic Freeze is a plain can with no hose or gauge, so factor in a separate charging kit.

• Choose the Super Tech Premium if you want a complete recharge kit with hose, gauge and PAG oil in one can and your system holds pressure.
• Choose the Interdynamics Arctic Freeze if your A/C is weak from a small leak or moisture and you already own a charging hose and gauge.
