my car’s AC system

When your car’s AC system begins to blow hot air rather than cool, it likely means you need a recharge. Performing this DIY service is an easy task with the proper guidance and quality tools. However, if you choose the wrong refrigerant type for your vehicle, you could cause unintended damage and void any warranty protection on your vehicle’s components.

The car ac recharge kit you choose should include the correct refrigerant for your vehicle. Look for the refrigerant type listed in your owner’s manual or on a sticker on the front frame of the engine compartment. You should also confirm that the recharge hose and coupler are compatible with your vehicle’s system. If the kit does not include a pressure gauge, you’ll need to purchase one separately. This is an essential tool to ensure that you deliver the right amount of refrigerant and don’t overfill your system.

Many cheap recharge kits also feature a stop leak sealer. The claim is that these chemicals can plug small leaks as the refrigerant and compressor oil run through your system. In reality, these sealers can clog hoses, compressors and pumps and damage your air conditioning system.

Recharge kits also fail to remove old refrigerant from the system. This is a critical step that needs to be completed before adding new refrigerant. A professional mechanic will clean out the existing refrigerant and moisture from your system before completing an ac recharge.

If you are unable to find an appropriate a/c recharge kit for your vehicle, a professional mechanic will be able to safely remove the existing refrigerant from your vehicle’s system and then add the correct amount of new refrigerant to restore your air conditioning’s function. They will also be able to identify the source of any leaks and replace any defective parts.

While a/c recharge kits make the job seem simple, it is actually considered a professional repair due to the use of hazardous liquids. A certified technician or mechanic is trained to safely handle this type of repair and dispose of the hazardous materials properly.

If you’re able to locate an appropriate a/c recharge kit for the type of refrigerant your vehicle requires, a simple do-it-yourself project can save you some money on a professional repair. With the right kit, you can have colder air again in no time. Just be sure to follow all safety instructions when working with refrigerant and remember that a complete inspection is still necessary by a certified mechanic to ensure your car’s A/C system is in good working order. You’ll enjoy your summer drives with a cool, comfortable ride and avoid the costly repairs that come with improperly performed DIY auto repair.
