Find Problem

Inspect air flow problems: If you're experiencing insufficient air flow from your vents, ensure that there are no blockages. Your cabin air filter might be dirty or completely obstructed. While the engine air filter is well-known, the cabin air filter can also impede air flow. Another potential cause is a malfunctioning blower motor. Before jumping to replace the AC compressors, always check the fuse box for air flow issues.

Conduct a comprehensive check: If you're unsure about the problem with your AC system, perform a thorough inspection. This is a cost-effective method that could save you money in the long term. Start by turning on your car's AC and eliminate any other distracting noises. Listen for any abnormal sounds from behind the console panel or within the engine. Additionally, assess the cooling efficiency of the AC. Look out for unusual odors as well, as they could indicate faulty components or blown fuses. Therefore, it's important to inspect the fuses too.

Monitor your AC's temperature: Similar to measuring internal body temperature with a thermometer during a fever, diagnosing potential issues with your car's AC compressor requires checking its temperature. Specifically, pay attention to the AC compressor clutch. While the AC is running, locate the compressor and identify the clutch, which appears as a small circular gear responsible for engaging the compressor belt. If the AC compressor clutch remains still despite the AC running, it indicates a problem with the compressor. You can try adjusting the belt tension or opt for a complete replacement of the AC compressor.

Detect refrigerant leaks: Just like a closed brake system in your car, any leaks in the AC system can have a detrimental impact. This can result in temperature fluctuations or even complete failure of the system. Although refrigerant leaks can sometimes be caused by a faulty AC compressor, it is not always the case. AC compressors, like any other car part, can eventually fail. While some are manufactured with the highest quality standards and rarely require replacement, most AC compressors will eventually fail.

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
