Buying Guide: Best AC Refrigerant for Cars

When your car’s air conditioning system isn’t cooling as it should, the problem might lie with the refrigerant. Choosing the right AC refrigerant is crucial for ensuring peak performance and prolonging the life of your vehicle’s AC system. Here’s a comprehensive guide to help you find the best AC refrigerant for your car.

Understanding AC Refrigerants

1. What is AC Refrigerant?

   • Refrigerants are substances used in HVAC systems to absorb heat and provide cooling. In cars, they circulate through the AC system, changing from gas to liquid and back to gas to facilitate cooling.

2. Types of Refrigerants

   • R-134a: The most commonly used refrigerant in vehicles manufactured before 2017. It’s relatively eco-friendly compared to older types but still has some environmental impact.
   • R-1234yf: A newer refrigerant that is more energy-efficient and has a lower environmental impact. It’s commonly used in newer car models post-2017.
   • R-12: An older refrigerant that’s no longer manufactured due to its harmful environmental effects.

Factors to Consider When Buying AC Refrigerant

1. Compatibility

   • Always check your car’s manual to find out which type of refrigerant it uses. Using the wrong type can cause damage to your AC system.

2. Environmentally Friendly Options

   • Look for products that are eco-friendly, especially those using R-1234yf, which has a lower global warming potential.

3. Included Accessories

4. Quality and Brand Reputation

   • Choose reputable brands known for quality, like A-CDelco, Red Angel, or AC Pro. Reading reviews can give insight into reliability and effectiveness.

5. Capacity

   • Ensure that the refrigerant you choose matches the required capacity for your vehicle’s AC system. It’s typically measured in ounces.

6. DIY vs. Professional Use
