About Our HVAC System Repair Services
HVAC problems can make a truck uncomfortable to operate and may affect visibility when heating or defrost performance is poor. Our team delivers HVAC system repair services at our Calgary shop, with a dedicated service bay for diagnostics, air conditioning service, heating repair, and electrical testing.
Mobile HVAC repair is also available when a truck or piece of equipment cannot easily be brought to the shop. Our technicians can inspect many HVAC problems on-site and determine whether the repair can be completed in the field or requires in-shop equipment.
HVAC Repair for Trucks & Heavy Equipment
Our Calgary shop supports heating, air conditioning, ventilation, and climate control systems on commercial trucks and applicable heavy equipment. Service can include diagnostics, leak checks, component repair, and system maintenance.
HVAC repair services can include:
- Climate Control System Inspection: Inspect the air conditioning, heating, blower, controls, and ventilation system to identify performance problems.
- Air Conditioning Repair: Diagnose refrigerant leaks, compressor concerns, poor cooling, and other faults that reduce AC performance.
- Heating System Repair: Inspect heater cores, coolant flow, controls, and related components when the cab does not warm properly.
- Blower Motor Repair: Test blower motors, resistors, wiring, and controls when airflow becomes weak, intermittent, or stops completely.
- Ventilation Repair: Inspect ducts, vents, actuators, and airflow controls when air does not move or distribute properly through the cab.
- Cabin Air Filter Replacement: Replace restricted filters that can reduce airflow and place additional demand on the blower system.
- Electrical HVAC Diagnostics: Test switches, sensors, wiring, relays, and control circuits when electrical faults affect heating or cooling.
- Mobile HVAC Repair: Complete suitable HVAC diagnostics and repairs at yards, job sites, and other accessible locations.
Signs Your HVAC System May Need Repair
Changes in temperature, airflow, or climate control operation can point to a problem developing within the HVAC system. These signs matter because poor heating or cooling can affect operator comfort, while weak defrost performance may also reduce windshield visibility.
Common signs include:
- AC Blows Warm Air: Poor cooling can indicate low refrigerant, compressor problems, electrical faults, or restricted airflow that prevents the system from cooling properly.
- Weak Airflow From the Vents: Reduced airflow can point to a clogged cabin filter, blower motor problem, damaged ducting, or ventilation control issue.
- Heater Blows Cold Air: Lack of heat can indicate coolant flow problems, heater core concerns, control faults, or other issues that prevent warm air from reaching the cab.
- Intermittent Fan Operation: A blower that cuts in and out may indicate a failing motor, resistor, relay, wiring connection, or control circuit.
- Poor Windshield Defrosting: Weak or uneven defrost performance can affect visibility in cold or wet conditions and may point to airflow, heating, or control problems.
- Unusual HVAC Noise: Clicking, rattling, squealing, or grinding can indicate blower motor wear, actuator problems, or debris inside the ventilation system.
- Refrigerant or Moisture Concerns: Poor cooling, oily residue around AC components, or repeated loss of cooling performance may indicate a leak that needs inspection.
