Special Tools Required to Use a Car AC Recharge Kit

A car AC recharge kit can help you keep your cool by letting you add refrigerant to the system when it runs low. They contain a canister of the appropriate type and a hose with a gauge, so you can easily monitor the pressure when adding refrigerant.

You can find these kits at auto parts stores, online and even in some grocery store aisles. The best ones will include a detailed owner’s manual and an easy-to-read temperature chart. They also come with a can of the appropriate refrigerant, LeakStop sealant to eliminate small leaks and gloves. They’re an inexpensive option that can save you the cost of professional service.

The most important tool in a car air conditioning ac car recharge kit is the can of the correct refrigerant. You can find this in the specifications section of your vehicle’s owner’s manual, or by checking the front frame of the engine compartment or the inside of the hood. You can also read the label on the front of the refrigerant can for this information.

If you don’t have the manual for your vehicle, check the specifications section of other cars with similar models to see what type of refrigerant is in use. Some recharge kits also include an ac recharge gauge, which is a handy way to make sure you’re not overfilling the system and damaging the compressor or hoses.

One of the biggest mistakes people make when using a DIY AC recharge kit is adding too much refrigerant to the system. The hose and gauge in these kits only measure the pressure on one side of the system, so it’s easy to overcharge the AC and end up with hot air blowing instead of cold.

A recharge kit can get your cool air flowing again, but it’s not a solution to a broken AC system. A certified mechanic will clean the entire system of old refrigerant, moisture and contaminants before charging it with new refrigerant. This will remove the causes of leaking and reduce the likelihood that you’ll have to pay for a more expensive repair job in the future. Unless you’re a seasoned automotive mechanic, it’s usually better to leave the AC repairs to the pros.

A licensed mechanic can use a visual inspection and may run a fluorescent dye to more easily find any leaks. Once the problem is found a professional can fix it and then return your car’s AC to its proper operation.

A faulty AC pressure switch will usually cause the AC compressor to not turn on. This is a relatively common problem in older cars. The solution is to disconnect the electrical connection on the compressor clutch and connect it to a power source that will provide constant current to the switch. Alternatively, you can use a jump wire to jump the switch to bypass the electrical connections and engage the compressor clutch. If this does not work you will need to replace the AC pressure switch.
