Air Conditioning Leak Diagnosis: What You Need to Know

Why Is My Car A/C Not Blowing Cold? 

At some point in your vehicle’s life, especially in warmer climates, your air conditioner may stop blowing cold air. When that happens, a professional Air Conditioning system diagnosis becomes essential to identify the problem—and one of the most common culprits is a refrigerant leak.

Can I Drive with an A/C Leak? 

Yes—you can still drive with a discharged A/C system. However, running the system without refrigerant long-term can cause seals to dry out, leading to more extensive and expensive repairs down the road. If caught early, a small leak is much more affordable to repair.
