How do I know if I might have a leak?
If your vehicle’s A/C isn’t blowing cold, it’s probably due to low refrigerant as a result of a leak. Most leaks are in rubber components such as O-rings, hoses, and gaskets.

Does refrigerant go bad?
No. The refrigerant in your vehicle’s air conditioning system never goes bad and never gets “used up,” so if your vehicle’s A/C system pressure is low it means there is a leak. This will need to be repaired in order for your vehicle’s system to hold refrigerant. If the system is able to maintain a charge for a period of two weeks or longer, it is possible to seal the leak with sealant such as A/C Pro® Super Seal. If it will not hold a charge for at least two weeks, it is recommended that a professional technician is sought out to help find and repair the leak.
