Super Tech Premium R-134a Refrigerant vs Super Tech R-134A A/C Recharge Kit

Both are Super Tech R-134a recharge kits with a hose and gauge, so the real split is can size and rating. The Premium kit carries a full 18 oz can with 17.7 oz of refrigerant plus 0.3 oz of PAG oil and conditioner, which suits a system that lost a lot of charge or a compressor that needs lubricant. The Recharge Kit's 12 oz can is the better pick for a small top-off, and its 4.6 rating from 2,493 ratings beats the Premium kit's 4.1 from 1,049. Owners of both call the process easy and credit the gauge with preventing overcharging; a few report cans arriving short or the spray stopping early.

  • Choose the Super Tech Premium R-134a kit if your system is low enough to need a full can, or if you want PAG oil and conditioner added along with the refrigerant.
  • Choose the Super Tech R-134a Recharge Kit if you only need a partial top-off and want the higher-rated, simpler 12 oz can.

  • Super Tech Premium R-134a Refrigerant: $32.80 at Walmart (last seen Nov 10)
  • Super Tech R-134A A/C Recharge Kit: $24.96 at Walmart (last seen Nov 1)

What reviewers say

Super Tech Premium R-134a Refrigerant

  • 4.1 / 51,049 ratings

Rated about 4.1 out of 5 across more than a thousand ratings. Owners mostly report cold air after a top-up and like having the gauge and hose included. Complaints center on cans that ran out before the system was full and on the gauge being hard to read.

What people mention
  • Cooling resultPraisedMany owners say the AC blew noticeably colder after charging.
  • Included gaugeMixedBuyers like having a gauge and hose in the box but some find the gauge hard to read.
  • Can quantityCriticisedSome owners needed more than one can to bring the system up to pressure.
  • LeaksCriticisedA few buyers found it did nothing because their system had a leak.

Super Tech R-134A A/C Recharge Kit

  • 4.6 / 52,493 ratings

Reviewers who got a good can call the kit easy to hook up and effective at getting the A/C cold again, and they like that the gauge helps prevent overfilling. A minority report a can that arrived not full or a unit that stopped spraying after about 15 seconds.

What people mention
  • Ease of usePraisedOwners say the can and hose connect quickly with no special tools.
  • Cooling resultPraisedReviewers report the A/C blows cold again after a top-off.
  • GaugePraisedThe built-in pressure gauge is credited with helping avoid overfilling.
  • ValuePraised

Questions and answers

Which kit is better for a system that is completely empty?
The Premium kit. Its 18 oz can delivers 17.7 oz of refrigerant plus PAG oil, which is closer to a full charge on most cars. The 12 oz kit is sized for topping off.
Do I need PAG oil?
Only if the system lost oil along with refrigerant, such as after a leak or component swap. For a simple top-off, the 12 oz kit without added oil is the safer choice.
Which one lasts longer?
Neither is a repair. Both are single-use cans, and the hose and gauge are reusable. How long the charge lasts depends on your system's leak rate, not the kit.
Is the 12 oz kit worth stepping down to?
Yes if you are only slightly low. It has the stronger rating record, and the smaller can lowers the risk of overcharging a system that only needs a little.
Can I use either kit on an R-1234yf system?
No. Both are R-134a only. Check the label under your hood before buying.
Why can't the Premium kit ship to some states?
R-134a sales are restricted in Washington, Vermont and California. The 12 oz kit carries an EPA registration number but still follows your state's rules.
