Patryk Mikiciuk is installing an air conditioning system using the Carfix 5-in-1 kit

Tests and reviews

Every driver knows the feeling: the first hot day of spring, you get in the car, set the fan to “Low,” and instead of an icy blast, a warm reminder of last year’s vacation wafts out of the vents. A trip to the mechanic? Long lines, waiting times, and a bill that can chill you to the bone more effectively than a broken AC.

In Patryk Mikiciuk’s latest video, he introduced a solution that promises to be a “game changer” in DIY car maintenance—Carfix. Does this DIY air conditioning recharge kit really work? We put it to the test using a Range Rover as an extreme example.

Extreme Conditions Test: Range Rover vs. Carfix

Patryk Mikiciuk decided to test the kit on a Range Rover whose air conditioning system was completely empty and was showing a temperature of 33 degrees coming from the vents [00:22:04].

What does the step-by-step process look like?

  • The kit is simple: Inside the box, you’ll find a can, a hose with a pressure gauge, and gloves [00:22:32].
  • Important technical note: Before attaching the tip to the can, make sure the needle is screwed in to prevent accidental leakage [00:22:40].
  • Procedure: Connect the kit, start the engine, and set the air conditioning to maximum cooling.
  • The result? For the massive Range Rover system, two cans were needed (each containing 235g of refrigerant). The end result? The outlet temperature dropped to near-zero or even below-zero levels! [00:24:50].

Why should you choose the Carfix 5-in-1 kit?

Desiccant: Chemically binds moisture inside the system without the need to create a vacuum. Eliminates the risk of internal corrosion and the freezing of expansion valves.

Aluminum sealant: An active formula that fills micropores and small leaks in metal system components (condenser, evaporator, pipes).

Seal Restorer: Restores elasticity to hardened O-rings and rubber components, ensuring a tight seal at connections.

Synthetic oil: Ensures full lubrication and quiet operation of the compressor. It reduces friction, which directly prevents the compressor from seizing up.

Refrigerant: An eco-friendly alternative to R134a with higher thermal efficiency. It operates at a lower working pressure, which effectively reduces the load on the entire air conditioning system.
