When paired with the Smart Chip Pro, the A/C Recharge Assistant provides you with a quick and accurate A/C recharge, so you can have cold air blowing through your vehicle again - without any worry of overcharging the system.

Overcharging your system produces the same result as undercharging: hot air in the vehicle cabin. So getting your refrigerant fill level correct is the key to recharging your A/C system.

SMART CHIP PRO (REQUIRED)
The Smart Chip Pro wirelessly pairs with the A/C Recharge Assistant and calculates optimum refrigerant fill level in real time based on outside temperature and humidity. The Smart Chip Pro is available exclusively at NAPA Auto Parts. Use the store locator to find the store nearest you: napaonline.com/en/-store-locator
