Refrigerant can leak slowly from your car’s air conditioning system over time, but recharging the system so it once again blows cold air is an easy DIY task and takes just about 15 minutes.
Are Air Conditioning Recharge Kits Worth It? No, they are not because they don’t fix broken AC systems. Instead, they simply recharge refrigerant and leave the cause of the problem unattended. So while a recharge may get cool air blowing again, it masks the real issue as it worsens.
AC recharge kits come in a variety of prices and capabilities. Some are just refrigerant in a can with a hose and a gauge. Others include supplies to diagnose issues beyond a low refrigerant pressure and make further repairs. Some of those can even be used to diagnose and recharge home HVAC systems.

Why is my car AC blowing warm air?
One of the most common reasons your car AC is blowing hot air is because of a refrigerant issue—specifically, a loss of refrigerant. This loss of refrigerant can occur either due to a leak or because your car’s refrigerant levels are too low.
Most cars hold between 28 and 32 ounces of refrigerant (or about 2—3 12oz cans), however larger vehicles and those with rear A/C will likely hold more. Check your vehicle manual for the system capacity for your specific vehicle.
What happens if you put too much Freon in a car?
If there is air and you fill it with Freon, you can expect your air conditioning system to not work properly. If you drive your car with an overcharged AC system, the compressor undergoes a lot more strain. Over time, it can possibly even damage the system.
What happens if I put too much Freon?
The Compressor: Excess refrigerant creates a danger called slugging. This is when extra refrigerant floods into the piston cylinders of the compressor when in a liquid state. Slugging can create many different problems such as broken valves, broken connecting rods, and significant damage to the compressor.

Compressor
If your car A/C stopped blowing cold air all of a sudden, it’s likely your compressor needs to be replaced. The compressor is the engine that drives the entire A/C system. If the compressor is not working or is lacking in oil, it has a tendency to break down and cause the entire system to fail.
