Interdynamics Arctic Freeze R134a Refrigerant vs EZ Chill Auto AC Recharge & Seal

Buy the EZ Chill kit if you want to recharge a system yourself without buying extra tools. It includes a reusable in-line gauge with a temperature dial and a push-button dispenser, so you can watch the low-side pressure as you fill. The Arctic Freeze can is a plain 19 oz R-134a refill with a leak sealer and a moisture and acid eliminator, but no gauge and no hose, so you need your own manifold or charging kit. Both are California-compliant R-134a products for older systems. Owners of either type report that a can only helps when the system still holds some charge; a system that is empty or losing refrigerant fast needs a leak repair first.

• Choose the Interdynamics Arctic Freeze if you already own a gauge and charging hose and want a straight R-134a refill with a leak sealer plus moisture and acid treatment.
• Choose the EZ Chill Auto AC Recharge & Seal if you want a self-contained kit with a reusable gauge and temperature dial so you can charge and monitor the system in one step.
