1. Compatibility: It is crucial to ensure that the leak sealer you choose is compatible with your car’s AC system. Check the product label or consult with an expert if you are unsure.

2. Type of Sealant: There are two types of sealants available – liquid and tape. Liquid sealants are poured into the AC system, while tape sealants are applied onto specific areas. Consider which type would be more suitable for your needs.

3. Effectiveness: Look for products that have been tested and proven to be effective in sealing leaks in car AC systems. Reading reviews from other customers can also give you an idea of its effectiveness.
