Heavy-Duty A/C Compressors for Semi Trucks – Used Parts for Reliable Cooling

Keep your drivers cool and comfortable mile after mile with high-quality A/C compressors engineered for heavy-duty and medium-duty trucks. The A/C compressor is the heart of the air conditioning system – circulating refrigerant, maintaining system pressure, and ensuring strong cold airflow even in high-heat, long-haul conditions. When a compressor begins to fail, it leads to warm air, reduced fuel efficiency, and costly downtime.

We carry OEM and aftermarket units compatible with major commercial truck manufacturers, including Freightliner, International, Kenworth, Peterbilt, Volvo Trucks, Mack, Western Star, and more.

Common Signs of a Failing A/C Compressor

If you notice any of the following issues, it may be time to replace the compressor:

• Warm or weak airflow from the vents.
• Loud grinding or squealing noises when A/C engages.
• Oil or refrigerant leaks around compressor housing.
• A/C system cycles on and off frequently or won’t start.

Replacing a faulty compressor protects the entire HVAC system – including the condenser, evaporator, and expansion valve – from further damage.
