Fundamentally, recharge kits are not bad. However, they often do more harm than good. They are designed with a stop leak which plugs small leaks as the refrigerant and compressor oil run through the system. Unfortunately, this method can easily clog the air conditioner components like the pump, hose, and compressor.
Are DIY AC recharge kits bad for your car?
This process can take many years — but, eventually, every vehicle will need its A/C system recharged. When you use a DIY canister to add more refrigerant, you can’t be sure how much is remaining in the system! This can lead to overcharging the system, which can cause significant damage.
Is it bad to use a AC recharge kit?

What happens if you add too much Freon to your car?
As a common side effect, excess freon gas can prevent the compressor from working at its capacity. In some cases, extra freon accumulates inside the compressor and results in subcooling or undercooling. In the worst of cases, the freon gas may even damage the internal mechanism of the compressor.
How do I know if my car AC needs recharging?
The most obvious symptom that a vehicle needs to be recharged is that there will be a noticeable loss in the overall cooling capability of the AC system. The AC system operates by circulating pressurized refrigerant, so if the amount drops too low it will eventually begin to affect the operation of the system.
Do you add Freon while the car is running?
You should use your car’s running engine and A/C when adding freon because: Opening up the air conditioner’s lines while not on will cause the freon to turn into a gas too quickly, causing your engine to run poorly or shut down.
