A/C & DPF Systems

Truck A/C Repair & DPF / Emissions System Service

Western Truck Exchange specializes in commercial truck A/C system repair and diesel emissions system service, including DPF diagnostics, cleaning, and repair. Modern trucks rely heavily on properly functioning emissions systems and climate control to remain compliant, efficient, and comfortable for drivers.

Our technicians diagnose and repair A/C performance issues such as refrigerant leaks, compressor failures, airflow problems, and electronic control faults. At the same time, we address DPF-related issues including regeneration failures, sensor malfunctions, soot accumulation, and fault codes that can place vehicles into derate or shutdown modes.

Using advanced diagnostic equipment and OEM-approved procedures, we restore emissions system functionality while ensuring compliance with California emissions regulations. Our A/C and DPF services are designed to keep trucks operational, compliant, and comfortable under real-world working conditions.
