Our Truck HVAC Services

HVAC System Inspection
Our skilled mechanics start every truck HVAC system repair with a full inspection and precise diagnosis. The first step is checking different components, such as the compressor, condenser, evaporator, blower motor, and all electrical connections. Then, we test air conditioning, heating, and ventilation performance to locate leaks, electrical faults, or worn parts. You get a clear report of what is working and what needs to be repaired. A thorough inspection ensures we fix it right the first time and saves you money by catching small issues before they become major problems.
Repair and Replacement of HVAC Components
Once the problem is identified, we repair and replace any failing component in your truck's HVAC system, including compressors, thermostats, condensers, cabin filters, and blower motors. Using high-quality parts, we restore your truck’s heating and cooling to peak performance, whether at our Coquitlam truck shop or through our mobile services. Our technicians complete most repairs the same day, since we stock common components to give you a reliable climate control system that works when you need it most.


Truck HVAC Maintenance
The best way to avoid expensive breakdowns and extend your truck's HVAC system's lifespan is through regular maintenance. We change filters, clean coils, check refrigerant levels, inspect belts and hoses for damage, and test all components to keep air ducts clear and performance steady. With our regular maintenance services, your truck’s HVAC system works year-round, keeping your drivers comfortable, your cargo safe, and reducing emergency repair costs.
