By my car AC if it’s blowing warm air with a kit
Over time, all cars lose some of the refrigerant gas that makes their air conditioning systems work. This happens because hoses and seals wear out, and the refrigerant leaks out. Depending on the age and condition of your car, you may need to recharge its A/C system. A DIY kit can do this job, but there are things you should know before trying it at home.
First, you need to know what type of refrigerant your car’s A/C system uses. Many kits include a can of R-134a refrigerant with a hose and gauge attached. This is the refrigerant that most modern vehicles use. Older vehicles used a different type of refrigerant, called CFC-12 or Freon. This type of refrigerant is no longer made because it depletes the ozone layer and poses health risks. Your owner’s manual can tell you what kind of refrigerant your vehicle’s A/C system uses.
The gauge on the a/c recharge kit for car tells you when to stop adding refrigerant. It also indicates the pressure of the A/C system. A professional technician can measure the system pressure with a special tool and determine how much refrigerant to add by weight. This ensures that the system has the correct amount of refrigerant, so it won’t be under or overcharged.

Once you’ve added the correct amount of refrigerant to your car, you can turn on the A/C and enjoy ice-cold air. If the air doesn’t cool, you may have a larger problem that needs professional attention. Check the compressor (the part that looks like a pulley system near the low-side port) to make sure it is spinning. If it isn’t, you probably have a big leak that needs to be fixed with an AC repair specialist.
One final thing to consider: Most recharge kits also include a “stop-leak sealer.” These products can do one of two things: they may not work at all, or they may temporarily plug leaks but then cause other problems by interfering with the compressor and hoses. This can lead to higher costs down the road and is why it is best to leave these kinds of repairs to a professional.
In summary, while you can use a recharge kit to get your car’s A/C system up and running, it’s best to let an experienced technician handle the professional repair of any major leaks or other problems that can be found when an expert inspects the A/C system. Don’t take any chances at home; it is too easy to damage your A/C system and end up paying more in the long run. Besides, DIY recharging won’t get the coldest A/C.
Professionals have specialized equipment that lets them evacuate and vacuum the A/C system, which is necessary to remove any contaminants. This helps the refrigerant to flow properly through the system and into the evaporator and condenser, where it will blow cool air. A professional recharge will also provide the most accurate and efficient results.
