🚙❄️Recharging the AC is simply the process of adding more refrigerant to the system. A recharge kit is really just a can of R134a refrigerant with a little bit of leak sealer mixed in, a hose that connects it to your car, and a gauge to measure how much of it is in your car. These kits cost around $20 to $50 in any auto parts store and are easy to use. At the repair shop, the average cost of an AC recharge is ~$123-$155, so you can save a lot of time and money by doing it yourself. Although recharging the AC on your car is the first thing to try when it stops working, this isn’t a guaranteed fix. The leaks may be too large for the recharge kit to fix, or perhaps your AC compressor has failed. If that is the case, your best bet is to take your car to a professional who is equipped to repair and refill air conditioning systems.
