A/C Pro Ultra Synthetic R-134a Car AC Refrigerant Kit ACP001, 18 oz

4.4· 1,482 ratings

Choose the A/C Pro Ultra Synthetic if your system is low and you want one 18 oz can with leak sealer, acid and moisture eliminators, and anti-wear additives, plus a reusable braided hose and dial gauge.

Pros
  • 18 oz can delivers more refrigerant per kit than the 12 oz Super Tech can.
Leak sealer can fix small leaks in hoses, gaskets and O-rings instead of just topping off.
  • Reusable braided hose and dial gauge stay useful for later checks.
  • Anti-wear additives and moisture and acid eliminators protect the system.
    • Cons
    • Cannot be sold or shipped to Washington, Vermont or California.
    • No price was given, so you cannot compare cost directly here.
    • Lower rating than the Super Tech kit: 4.4 vs 4.6.

    R-134A Auto A/C Recharge Kit – Refrigerant + Charging Hose with Gauge

    4.6· 2,493 ratings

    Choose the Super Tech kit if you want the cheapest way to top off a system that holds pressure, and a 12 oz can plus gauge is enough.

    Pros
    • Lowest recent price was $22.32, well below most 18 oz kits.
    • 4.6 out of 5 from 2,493 ratings, higher than the A/C Pro kit.
    • Self-sealing can mates directly to the included hose.
    • Gauge helps avoid overcharging during a top-off.
    Cons
    • Only 12 oz, so a fully empty system may need a second can.
    • No leak sealer listed, so it will not fix a leak.
    • No written warranty.
    • Some reviewers report cans arriving not full or stopping spray after about 15 seconds.

    What reviewers say

    A/C Pro Ultra Synthetic R-134a Car AC Refrigerant Kit ACP001, 18 oz

    Owners generally report cold air returning after a top-up and like the gauge and hose. Complaints center on cans that ran out before the system was full and on leaks that came back.

    Pros
    • Restores cold air on cars that had slowly lost charge
    • Gauge is easy to read and reusable
    • Hose feels sturdier than other kits
    Cons
    • One can often is not enough for a fully empty system
    • Leaks return when the real problem is a bad component
    • Price per ounce is high versus plain refrigerant

    R-134A Auto A/C Recharge Kit – Refrigerant + Charging Hose with Gauge

    With 4.6 out of 5 from 2,493 ratings, most owners find the kit easy to hook up and say it gets the A/C cold again. A few report a can that arrived partly empty or a unit that stopped spraying after about 15 seconds.

    Pros
    • Easy to hook up and use
    • Works as described and gets the A/C cold
    • Included gauge helps avoid overcharging
    • Good value for what you get
    Cons
    • Bottle arrived not full
    • Stopped spraying after about 15 seconds
    Reviews
    • Useless

    Questions and answers

    Which kit is better for a system that has slowly lost charge?
    The A/C Pro kit. Its 18 oz can plus leak sealer treats small leaks in hoses, gaskets and O-rings while it recharges. The Super Tech kit only adds refrigerant.
    Is the Super Tech kit worth the lower price?
    Yes, for a simple top-off on a system that holds pressure. At $22.32 to $24.96 it costs less, but you get 12 oz and no leak sealer.
    How much refrigerant does each kit contain?
    A/C Pro has an 18 oz can. Super Tech has a 12 oz can. A system that is fully empty will likely need more than one Super Tech can.
    Can I buy either kit in Washington, Vermont or California?
    The A/C Pro kit is not sold or shipped to WA, VT or CA. The Super Tech listing shows no state restrictions, only a Prop 65 warning.
    Which has better ratings?
    Super Tech: 4.6 out of 5 from 2,493 ratings. A/C Pro: 4.4 out of 5 from 1,482 ratings. Both are close.
    Do both work on any car?
    Only on vehicles that use R-134a, which is most 1994 and newer cars. Neither works on R-1234yf systems.
