HVAC Repair in Lac La Biche, AB
Your truck’s HVAC system isn’t just about comfort—it also plays a role in safety, defrosting, and driver alertness. When your system fails, it can quickly turn into a serious issue, especially in extreme Alberta weather. At Ethos Mechanical, we offer complete HVAC diagnostics and repairs for heavy-duty, medium-duty, and light-duty diesel vehicles. Our HVAC services include:
- Compressor Replacement – The compressor is the heart of the AC system. If it fails, your cabin won’t cool. We replace faulty compressors to restore proper air conditioning function.
- Blower Motor Replacement – A malfunctioning blower motor prevents airflow through the vents. We replace worn motors to ensure proper circulation for heating and cooling.
- Heater Core Repair – If your cabin isn’t warming up, a clogged or leaking heater core could be the issue. We restore heat flow by flushing or replacing the core.
- AC Leak Detection and Recharge – Low refrigerant levels from leaks reduce cooling performance. We locate leaks, seal the system, and recharge refrigerant to optimal levels.
- Control Panel and Sensor Diagnostics – Electrical issues in HVAC systems can cause erratic performance. We diagnose faulty controls, actuators, or sensors and perform targeted repairs.
