Comfort in the cab affects driver alertness and safety, whether it's a summer heat wave or an Ontario winter. Ontario Truck Repair repairs air conditioning, heating and ventilation systems on commercial trucks at our Mississauga facility.

What we repair and service

For AC systems we offer AC compressor replacement, refrigerant recharge, condenser repair or replacement, evaporator core service and complete AC system diagnostics.

We also work on ventilation, including duct cleaning, vent repair and replacement, cabin air filter replacement, air flow diagnostics and AC control repair.

Signs your truck may need AC or heating service

  • Weak cooling or air that never gets cold
  • Little or no heat from the vents
  • A defroster that won't clear the windshield
  • Odd smells or noises when the system runs
  • Weak airflow even with the fan on high

Why it pays to fix it early

An AC system that cools poorly usually has a leak, a failing compressor or a blocked condenser, and running it that way can damage the compressor. In winter, a weak heater or poor defrosting is a visibility and safety issue. Having the system checked before the season starts avoids rushed repairs when the weather turns.

Why Mississauga fleets choose Ontario Truck Repair

Climate control systems combine mechanical, electrical and cooling parts, so accurate diagnosis comes first. Our certified technicians receive regular training and we invest in state-of-the-art diagnostic equipment. We use OEM or premium aftermarket parts backed by strong warranties (coverage depends on the repair and parts used), and each repair goes through multiple quality checks. Book ahead of the seasons, and have your system working before you need it.
