Heavy-Duty Diagnostics That Find the Real Fault
Truck AC problems are not always “low refrigerant.” We run pressure, temperature, and electrical checks to pinpoint the failure so repairs solve the cause, not the symptom.
Truck AC Repair Calgary
Truck drivers spend long hours in their cabs, and a failed air conditioning system affects comfort, alertness, and safety. City Wide Radiator provides professional truck AC repair Calgary fleets and owner-operators rely on for semi-trucks, delivery vehicles, buses, and heavy equipment. Whether you need aluminum radiator repair Calgary services or complete cooling system diagnostics, our team brings over 50 years of experience working on commercial cooling systems to quickly identify AC issues and repair heavy-duty equipment.
Heavy-Duty Air Conditioning Service for Commercial Vehicles
Truck AC systems operate under harsher conditions than passenger vehicles. Larger cabs, constant vibration, high engine heat, and long run times require components and service methods designed for commercial duty.
Many trucks also use dual systems for cab and sleeper areas or auxiliary power unit (APU) air conditioning. We service these systems correctly so drivers stay comfortable on the road and at rest.

Heavy-Duty AC Systems Require Specialized Service
Higher Capacity Systems – Truck cabs are larger and experience more heat soak from engine compartments. AC systems must work harder and longer.
Dual System Configurations – Many trucks run separate AC systems for the cab and sleeper. Some have APUs with their own AC.
Extended Service Intervals – Commercial vehicles rack up miles quickly. By the time AC problems become noticeable, component wear may be extensive.
