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.

Symptoms of a Bad HVAC System

Your truck’s HVAC system gives clear signals when something is not working properly. Ignoring the symptoms impacts focus, safety (especially as colder, wetter weather arrives), overall performance, and turns a simple fix into expensive truck repairs.

Watch for these common HVAC warning signs:

  • Weak, uneven, or no airflow from vents
  • Air conditioning blowing warm air
  • Heating system producing cold air
  • Moisture buildup, foggy windows inside the cabin
  • Poor defrosting performance
  • Foul or mould odours coming from the vents
  • Strange noises (clicking, grinding or squealing)
  • System won't turn on or have issues with controls
  • Refrigerant leaks under the truck
  • Faulty or stuck compressor clutch

If you notice any of these signs, schedule a truck HVAC system repair before it turns into a breakdown.
