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 cabi

Warning sign

• The Compressor Isn't Activating: If your car's AC system is not producing cold air when it is turned on, the compressor may be the issue. To check if power is reaching the compressor, use a multi-meter. If no power is reaching the compressor, it is recommended to take your car to a mechanic or an auto electrician for further diagnosis and repair.

• Warm Air Instead of Cold Air: Another common indication of a failing AC compressor is when the air conditioner starts blowing warm air instead of cold air. This could be due to a refrigerant leak or insufficient refrigerant gas levels. In some cases, replacing the entire AC system may be necessary to resolve this problem.

• Loud Noises Emanating from the Compressor: A failing AC compressor may produce loud noises, a clear sign of its deteriorating condition. These noises could be a result of a faulty clutch or worn-out bearings. They are often described as grinding sounds coming from under the hood when the AC system is activated.

• Oil Leak Under the Vehicle: An AC compressor in poor condition can lead to oil leaks. This occurs due to excessive heat and pressure within the engine bay, leading to worn-out compressor seals over time. If you notice any liquid leaking underneath your car, it is essential to have it inspected promptly to prevent further damage.
