    4.75 Stars for an EZ AC Fix

    I'm not an expert, so I really liked that the refilling process was simple.1. Wait until the weather outside is between 75F to 85F (because that's what temperature gauge was calibrated to(some other refrigerants have a variable weather adjustment, but not this company)).2. Turn your car on, set the AC to full blast and wait a few minutes.2. Screw the small end of the hose to the refrigerant can head.3. Attach the big end of the hose to the low side port by holding back the quick release of the hose and then letting go of it when the hose is on the port.4. Let the gauge measure the pressure. If your gauge is not working correctly, it's probably because your compressor is not spinning (it stops spinning when your car is really low on refrigerant). You need to add a bit of refrigerant at this point just to get a pressure reading.5. Take the blue cap off the can and spray for a couple minutes. Make sure to have the... 5/5 P - See all my reviews Verified Purchase(What's this?) This review is from: Interdynamics MAC-134 EZ Chill Refrigerant Refill with Charging Hose and Gauge - 18 oz.

    2003 Jetta TDI A/C Recharge Success

    My A/C pump was not engaging and the dual radiator fans were not turning on when I had the key in the on position and the AC button pressed in. I used this product and now the A/C pump is turning on and the AC is running somewhat cold.Instructions are a little vague so I will share with you my process.TO TEST: I tested with the car engine off to see if the pressure was low. Pressure was low so I turned the car on to fill the system.TO FILL: Car engine must be running the entire time (regardless of vehicle). The 134a refrigerant cannot enter the system with the car engine off. When you press the button to fill the gauge jumps up to the red 'danger' level. This is normal all you do is release button to see the effects of your fill. During the fill, I pressed the button on for 4 seconds and released the button to check my progress. Once I noticed the system pressure did not change much (when button was not pressed in) I incresed the button on time to... 4/5 Danielle "daniellec81" (Walla Walla, WA USA) - See all my reviews This review is from: Interdynamics MAC-134 EZ Chill Refrigerant Refill with Charging Hose and Gauge - 18 oz.

    Great stuff and yes you can order it without a license...

    0 5/5 Handy Technician - See all my reviews Verified Purchase(What's this?) This review is from: Interdynamics MAC-134 EZ Chill Refrigerant Refill with Charging Hose and Gauge - 18 oz. (Automotive) I was very pleased to be able to receive this product from Amazon, I know that the EPA has lifted restrictions on the sales of Freon to only certified technicians but surprisingly the Automotive stores in my area told me they still wouldnt sell it to just anyone... I told them I'ld get it on-line, good luck with that was their response. I received and installed this product and my AC works good as new!!! 0 Help other customers find the most helpful reviews  Was this review helpful to you? , July 29, 2011
