Here's why you should leave it to a professional:
* System Diagnostics: Before adding refrigerant, a technician needs to diagnose the problem. Low refrigerant could be a symptom of a leak, and adding refrigerant without fixing the leak is a waste of money and could damage the compressor. They'll use specialized tools to identify leaks and pressure check the system.
* Specialized Tools and Equipment: Adding refrigerant requires a refrigerant recovery and recharge machine. This machine vacuums out the existing refrigerant (important for environmental reasons and system health), checks for leaks, and then adds the correct amount of refrigerant and oil. These machines are expensive and require training to use safely.
* Safety: Refrigerant is under high pressure and can cause serious injury if handled improperly. Improper handling can also lead to environmental damage.
* Refrigerant Type: Using the incorrect type of refrigerant can severely damage your AC system. A professional will know the correct type for your vehicle.
Instead of trying to do it yourself, take your Buick Century to a qualified mechanic or an automotive air conditioning specialist. They have the proper tools, knowledge, and experience to safely and effectively diagnose and repair your AC system. The cost of professional service will be far less than the cost of repairing damage caused by a DIY attempt.
