Your manufacturers often recommend you get an oil change every ~6 months. Most vehicles need a brake fluid flush every few years. However, you will not find any manufacturer recommendations about AC refrigerant refills. This is because most vehicles do not need refrigerant refills unless there is an issue.

Your refrigerant exists in a sealed system between your compressor, condenser, expansion valve, receiver/drier, and evaporator. It uses the same refrigerant over and over for the lifespan of your vehicle. As such, low refrigerant is a sign that there is a leak somewhere in your system. Repairing your cars air conditioner involves finding and addressing the source of this leak.

Why You Should Leave It To The Professionals

There are various types of at-home A/C recharge kits on the market. However, adding new refrigerant without evacuating the old, potentially contaminated refrigerant won’t ensure that you are getting the best performance from your vehicle’s A/C system. Just topping off the refrigerant may or may not bring the cold air conditioning back and if it does bring the cold air back, the question will be for how long because the leak was never fixed. Without diagnosing the root cause of the problem, any benefit will be short term at best. Further, be aware that adding too much refrigerant can reduce the system’s cooling ability and potentially cause the whole system to shut off.
