Emergency situations

Some emergency indicators that something is wrong with your compressor include:

• Weird noises: This could be caused by a worn or broken belt/pulley. There are several other issues that may need to be addressed immediately.
• Burning smell: The compressor wiring may be damaged or burned.
• Leaking dashboard: It could be caused by a clogged hose or drain. Age and moisture can also cause your system to leak.

If you notice any of these issues, it's important to fix the problem as soon as possible.

General system

Each system may vary slightly per vehicle. For example, some may include an orifice tube whereas others have an expansion valve. This means the system has up to 7 components including:

• Compressor: compresses cool refrigerant gas into hot refrigerant gas
• Condenser and fan: converts hot refrigerant gas into a hot liquid at high pressur
• Receiver Dryer: temporarily stores refrigerant when not needed by the system
• Expansion (TX) Valve / Orifice Tube: regulates refrigerant flow / creates pressure drop
• Evaporator: cools air before entering cabin
• Heater Core: warms air before entering cabin (uses engine coolant rather than refrigerant)
• Blower Motor: fans hot or cold air into the cabin

Troubleshooting and DIY Checks

Performing basic checks and troubleshooting for common AC problems can help identify issues and potentially resolve them. However, it’s important to prioritize safety and consult a professional technician if needed. Here is a step-by-step guide to troubleshooting and performing DIY checks on your car AC system:

• Safety First: Before starting any checks, ensure that the engine is off, the car is in a well-ventilated area, and the AC controls are set to off.

• Inspect Fuses: Begin by checking the AC system’s fuses. Locate the fuse box, usually found in the engine compartment or under the dashboard. Refer to the owner’s manual or fuse box cover for the specific AC fuse location. Inspect the fuse visually to see if it’s blown or damaged. If you find a blown fuse, replace it with a new one of the same rating.

• Check Refrigerant Levels: Insufficient refrigerant levels can result in reduced cooling performance. Locate the low-pressure port of the AC system, usually marked with an “L” or labeled as low-side. Attach a pressure gauge to the port and check the reading. If the pressure is below the recommended level, it may indicate a refrigerant leak. In such cases, it’s best to consult a professional technician for further diagnosis and repair.

• Inspect the HVAC system's components for any visible signs of damage or leaks. Begin with the compressor, located near the engine. Look for oil stains or refrigerant residue, which can indicate a leak. Next, examine the condenser, usually positioned in front of the radiator. Check for bent fins or debris that may block airflow. Also, inspect the HVAC hoses for any cracks or leaks. If you notice significant damage or suspect a leak, it is advisable to seek professional help.

• Test the HVAC System: Start the engine and turn on the HVAC to its maximum setting. Observe the system's behavior. Pay attention to the airflow from the vents, the air temperature, and any unusual noises. Weak airflow or warm air could indicate a problem with the blower motor, cabin air filter, or ductwork. Strange noises may point to a faulty fan or compressor. Unpleasant odors could be a sign of mold or bacterial growth. If you encounter any of these issues, it is recommended to consult a professional technician for a detailed inspection.

• Recharge the HVAC System (if applicable): Some HVAC systems may require recharging if the refrigerant level is low. It is important to note that handling refrigerant requires specific equipment and expertise. If you believe a recharge is necessary, it is recommended to consult a qualified technician to ensure proper procedures are followed
